 is unlocking the value of alternative assets, starting with the $5 B trading-card market. We let collectors buy, sell, vault, and finance their cards in one place and we are backed by leaders at Stripe, Coinbase, Seven Seven Six, and pro athletes like Tom Brady and Giannis Antetokounmpo. Our next frontier is real-time pricing at scale—the Alt Value that powers every trade, loan, and product on the platform.

At Alt, we're flipping the script on investing - starting with trading cards. Our mission is to turn alternative assets
into investable, liquid markets, and we're already making serious noise in a $60B+ category. Think of us as the
modern stock market for culture-backed assets. First stop: trading cards. Next stop: everything else.
With over $100M raised from the likes of Alexis Ohanian, founders of Stripe and Coinbase, and top-tier athletes like
Tom Brady, Candace Parker, Giannis Antetokounmpo, Alex Morgan, Kevin Durant, and Marlon Humphrey, we're
building a platform that powers collectors, investors, and sellers alike.

We are hiring a Controller to build and own Alt's accounting function for the first time. Today Finance is a one-
person team supported by an outsourced accounting provider — you will bring that function in-house, close out our
external audit, lead our conversion to full US GAAP accrual accounting, and take ownership of tax and systems
work, reporting directly to the Head of Finance. Alt is fully remote (US), and this is a build-from-scratch role at an
early-stage company: you’ll write the policies, checklists, and controls Alt has never had, and grow a small team
behind you as volume scales. If you want to own a function end-to-end rather than inherit one, this is that job.

• Own the monthly close end-to-end and drive it toward a 5-day, fully reconciled, audit-ready close, with nothing
aged past 30 days.
• Lead the conversion from mixed cash/accrual to full US GAAP accrual across every revenue stream: auctions,
the fixed-price exchange, lending and cash advances, and partner revenue.
• Own the chart of accounts and revenue recognition policy, and lead the work to tie GL entries back to our
source-of-truth data warehouse (e.g., Snowflake) and feed it directly into QuickBooks or a future ERP, so
revenue postings stop being a manual month-end exercise.
• Be the primary point of contact for our external auditors: own the PBC list, walkthroughs, and full close-out of
open items.
• Own the tax compliance calendar (corporate and fund-level returns, K-1s, state and local filings, 1099s, and the
annual R&D credit study), working with outside tax advisors.
• Own covenant and borrowing-base reporting for our asset-backed credit facility, partnering with the Head of
Finance on lender compliance.
• Own day-to-day accounting operations (AP/AR, reconciliations, fixed assets, spend controls, and corporate card
and vendor administration), and manage our outsourced provider with a mandate to bring the work in-house
over time.
What You Bring
• 8+ years of progressive accounting experience, including hands-on controllership in industry.
• Deep US GAAP knowledge, with direct experience converting a company from cash or mixed-basis accounting
to full accrual.
• Proven ownership of an external audit relationship — PBC lists, walkthroughs, sample testing, and auditor
communication.
• Experience in a marketplace, fintech, or lending environment, with comfort in principal-vs-agent revenue
questions and reserve/receivable accounting.
• Fluency with QuickBooks, a modern spend platform (e.g., Ramp), an HRIS (e.g., Rippling), and enough
SQL/BI comfort to tie GL entries back to source data, ideally including running an integration between a data
warehouse and an accounting system.
• Experience managing an outsourced, fractional, or offshore accounting team.
• Nice to have: asset-backed lending or covenant/borrowing-base reporting, and experience preparing a company
for institutional fundraising or M&A diligence.

• The chance to build and own Alt's accounting function from the ground up, with a clear path to leading a team
as it grows.
• Meaningful early-stage equity in a company backed by top-tier investors and founders.
• $100/month work-from-home stipend
• $200/month wellness stipend
• WeWork office stipend
• 401(k) retirement benefits
• Flexible vacation policy
• Generous paid parental leave
• Competitive healthcare benefits, including HSA, for you and your dependent(s)

Base salary of $165,000 to $190,000, plus equity. Actual offer may vary based on experience and location

Alt is seeking a Senior Recruiter who can find the people other recruiters can't. Our roles sit at unusual intersections — engineers who understand marketplaces, pricing experts who know trading cards, operators who thrive in ambiguity — and filling them takes creative, relentless sourcing, not job-post-and-pray. You'll own searches end-to-end, from intake through close, and treat every candidate interaction as a reflection of our brand, whether or not they get the offer. We're an AI-native company, and we expect this role to be too: you'll lean into Claude and other AI tools daily to source smarter, screen faster, and run a recruiting function that punches far above its headcount.

Own full-cycle recruiting across technical and non-technical roles — intake, sourcing, screening, interview coordination, offer, and close

Build creative sourcing strategies for niche, hard-to-find profiles: uncommon skill intersections, passive candidates, and talent pools others overlook

Deliver an exceptional candidate experience at every touchpoint — fast responses, honest communication, thoughtful rejections, and a process candidates rave about regardless of outcome

Run Greenhouse as a power user: pipeline hygiene, scorecards, structured interview plans, automations, reporting, and data the leadership team can act on

Lean into AI across the entire funnel — using Claude and other tools to build sourcing searches, personalize outreach at scale, synthesize interview feedback, and automate the repetitive parts of recruiting

Partner closely with hiring managers to sharpen role definitions, calibrate on profiles quickly, and keep searches moving with clear weekly updates

Use pipeline data to diagnose bottlenecks, improve pass-through rates, and continuously tighten time-to-fill

Help build Alt's employer brand and talent networks in the collectibles, fintech, and marketplace communities

5+ years of full-cycle recruiting experience, with significant time at fast-growing startups where you were finding niche, hard-to-fill profiles — not running high-volume commodity searches

A sourcer at heart — proven ability to build pipelines from scratch through creative search strategies, deep outbound work, and genuine candidate relationships

A track record of exceptional candidate experience, and strong opinions about what great looks like

Deep Greenhouse expertise — you've administered and optimized it, not just logged interview feedback in it

Strong AI fluency, specifically with Claude — you use AI daily in your recruiting work, can show concrete examples of how it's made you faster or better, and are excited to push what's possible

Excellent judgment reading signal on candidates quickly, especially for roles where the ideal profile doesn't fit a standard template

A quick learner, a self-starter able to work autonomously and handle the pressures of an increasing level of responsibility

Experience recruiting in marketplaces, fintech, collectibles, or other trust-sensitive consumer categories

Experience building recruiting processes, tooling, or employer brand from an early stage

Ground floor opportunity as an early member of the Alt team; you'll directly shape the direction of our company. The opportunities for growth are truly limitless.

An inclusive company culture that is being built intentionally to foster an environment that supports and engages talent in their current and future endeavors.

100% remote — work from anywhere in the US

Competitive healthcare benefits, including HSA, for you and your dependent(s) (US only)

Alt's compensation package includes a competitive base salary benchmarked against real-time market data, as well as equity for all full-time roles. The US base salary range for this role is:  $175,000- $180,000 Offers may vary from the amount listed based on geography, candidate experience and expertise, and other factors.

Startup Experience

AI Proficiency

Alt is seeking a Senior Recruiter to lead full-cycle recruiting for technical and non-technical roles. The role focuses on creative sourcing for niche profiles and leveraging AI tools like Claude to optimize the recruiting funnel. The ideal candidate will have deep Greenhouse expertise and a track record in fast-growing startups.

Senior Recruiter 

We're hiring a Senior Machine Learning Engineer who thrives on owning models end-to-end, from research through production. In this role, you'll own productization of Alt's pricing and underwriting models — the systems that turn raw card and market data into the Alt Value and cash advance terms that every buyer, seller, and lender on the platform depends on. You'll be the person who matures models to production-grade services, keeps them accurate and fast at scale, and pushes the boundary of what we can automate.

Alt is at an inflection point — our marketplace is scaling fast, and our pricing intelligence infrastructure has become a genuine competitive moat. We've proven that model-driven pricing works; now we need to push coverage, accuracy, and speed further while bringing down the overhead to run it. This is a high-ownership opportunity to take our pricing and underwriting models from "working" to "excellent" — and to define the ML infrastructure standards that will scale with the company for years to come.

Optimize our pricing models to significantly reduce infrastructure costs while maintaining and improving their accuracy, especially for high-value assets.

Iterate on our underwriting model to maximize cash advance disbursements while maintaining target risk thresholds and default rates.

Lead the full ML lifecycle from model training and feature generation to production deployment and monitoring.

Collaborate closely with our Expert Pricers to become a domain expert in the trading card market and inform model improvements.

Design and execute experiments and backtesting to discover and validate new features that improve the models’ predictive power and coverage.

Own the models’ AWS infrastructure, writing code for our pricing APIs to ensure the models can serve at scale and with low latency.

 Model-Based Pricing Coverage (% of cards confidently priced by models vs. manually)

Pricing Freshness (End-to-End Model Orchestration Time)

Underwriting Performance (Advance disbursement rate vs. Target default rate)

Shipped leaner, more accurate pricing models. 

You've cut infrastructure cost meaningfully while improving accuracy, especially on high-value assets.

You've iterated on the underwriting model to increase cash advance disbursements without breaching risk thresholds.

You're a go-to partner for the pricing team — you understand the domain deeply enough that your model changes reflect real market judgment, not just data.

The pricing APIs are faster, more observable, and easier to reason about, with monitoring in place to catch model drift or degradation before it hits customers.

7+ years of engineering experience, with 5+ years building and shipping production ML/AI models.

Deep proficiency in production-grade Python and SQL, including building custom feature-engineering pipelines (not just off-the-shelf scikit-learn). Think time-decay weighting, leakage-safe k-fold cross-validation, and cascading fallback/imputation logic.

Experience training and validating gradient-boosted or ensemble estimators against strict accuracy/error tolerances, with segment-specific tuning (e.g., by category or asset type).

Experience leveraging LLMs, foundation models, and AI dev tools for both internal tooling and user-facing product use cases in production.

Experience with MLflow or a comparable tool for experiment tracking and model registry/versioning.

Comfortable owning production model-serving infrastructure on AWS — capacity planning, auto-scaling, and diagnosing memory/timeout failures at scale.

Experience with CI/CD pipelines, orchestrating production workflows, and IaC for provisioning and modifying cloud infrastructure.

Pragmatic and focused on delivering value incrementally rather than pursuing perfection.

Experience with real-time or low-latency models serving at scale.

Previous startup experience — you understand and thrive on the pace, adaptability, and ownership required in a fast-moving environment.

Interested in or knowledgeable of trading cards, collectibles, or alternative asset markets.

A seat at the table to help shape the future of Alt and the alternative asset space

Autonomy and ownership on projects that matter

Competitive healthcare benefits, including HSA, for you and your dependent(s)

 $235,000-250,000 plus equity. Offers may vary based on experience, location, and other factors.

We’re looking for a Senior Fullstack Engineer who wants to build the financial engine of our platform. You’re not just building a checkout flow; you’re 

 that makes this marketplace work. You’ll join a high-impact team responsible for our custom double-entry ledger, payment provider integrations, and our core lending products.

If you have a "measure twice, cut once" mindset for backend integrity but still move with a bias toward action on the frontend, you’ll thrive here.

 Build and maintain our custom-built double-entry ledger system to ensure every cent is accounted for across the platform.

 Design and scale our lending products—from the logic of credit disbursements to the automated lifecycle of loan management.

 Design and implement robust integrations with payment gateways and banking partners, ensuring 99.99% reliability and seamless reconciliation.

 Create high-trust user interfaces for payments and lending that make complex financial actions feel simple, transparent, and secure.

 Make thoughtful trade-offs between rapid feature shipping and the uncompromising correctness required for financial systems.

 Level up the team through rigorous code reviews, technical documentation, and mentorship.

 You understand that in payments, "mostly working" is a failure. You think deeply about idempotency, race conditions, and data consistency.

 You don't just build a "pay button"; you understand the flow of funds and how to communicate financial status clearly to the user.

 You’re energized by the challenge of building a ledger or a lending engine from the ground up.

 You know when to build a custom internal solution and when to leverage a third-party API to get the job done.

 with a heavy focus on backend systems (Python, Postgres, AWS) and a proven ability to build modern frontends (React, TypeScript).

 You’ve worked with ledgers, payment processors, or lending products and understand the complexities of moving money.

 You are an expert in SQL and relational database design—you know how to write a transaction that won't fail under load.

 A track record of taking a complex financial feature from a technical design doc all the way to a polished UI in production.

 Experience with distributed systems, credit/risk modeling, or the alternative asset space.

 $140,000-$180,000, plus equity. Offers may vary based on experience, location, and other factors.
