We're looking for a Senior Backend Engineer who owns systems, not just services. You'll design the backend that moves money for millions of people — which means correctness, resilience, and performance aren't nice-to-haves, they're the job.

You'll work close to Product and to other engineering teams, shaping how our platform scales as we grow. This is hands-on: you'll write code, make architectural calls, and be on the hook for how your services behave in production. The growth path here rewards engineers who go deep, raise the bar around them, and make the system better than they found it.

Design and build robust, scalable backend services in Node.js and NestJS (Express).

Create and maintain high-performance RESTful APIs that other teams can build on with confidence.

Build for financial correctness — idempotency, reconciliation, retries, and well-defined failure states.

Model and manage relational data, primarily in PostgreSQL, with performance and integrity in mind.

Make architectural and system-design decisions, and own the trade-offs behind them.

Ensure optimal service performance and own production deployments end-to-end.

Raise the engineering bar through code reviews, pairing, and clear technical standards.

Mentor engineers and lead technical discussions, leaving the team stronger than you found it.

Move fast across multiple workstreams in a dynamic, high-growth startup environment.

Bachelor's degree in Computer Science or a related field, or equivalent practical experience.

5+ years of backend development experience, with solid depth in Node.js and NestJS (Express).

Proven experience designing and operating RESTful APIs in production.

Advanced knowledge of relational databases, preferably PostgreSQL.

Experience writing unit and integration tests, and treating quality as part of delivery.

Strong grasp of design principles and architectural patterns.

Track record of shipping features independently and owning service performance in a fast-moving context.

Ability to communicate complex technical concepts clearly, and to mentor others effectively.

Excellent problem-solving and analytical thinking, with genuine curiosity about new technology.

Experience with cloud platforms, specifically Google Cloud Platform (GCP).

Knowledge of containers and orchestration, such as Docker and Kubernetes.

Experience with messaging and queuing systems like RabbitMQ, Kafka, or Pub/Sub.

Experience building in fintech, payments, or credit.

With AUSD, stablecoins become programmable, composable, and ubiquitous by default.

We believe digital dollars should be a public good: trusted, accessible, and built for real-world utility. Our mission is to drive adoption through customizable, user-friendly on-ramps that make stable, dollar-based value available onchain.

We're backed by world-class investors including Paradigm and Dragonfly, and we're growing a team to reimagine how value moves online.

We're intentional about who we bring on. If you're passionate about stablecoins and want to help create more open, intuitive ways for people to engage with money, let's talk.

We bring the discipline of high-performance finance teams and the creativity of a fast-moving crypto-native startup. We're a small, mission-driven group of builders who move fast, sweat the details, and hold a high bar for excellence, in product, code, and culture.

You'll be joining a tight-knit team that values clear thinking, extreme ownership, and high-velocity decision making. We operate in short feedback loops, support one another without ego, and are deeply motivated by the opportunity to build foundational infrastructure for the future of money.

 to take end-to-end ownership of features and products across the stack, from Agora interfaces to reliable backend infrastructure. You'll work closely with product, design, operations, finance, and our external partners and customers to gather requirements, prototype quickly, and ship with confidence. You have strong product taste, a bias toward MVP thinking, and you're as comfortable reasoning about user experience as you are about backend systems, API designs or database schemas. Our stack includes TypeScript, React, REST APIs, Docker, Kubernetes, Prometheus, and Grafana. This is a role where you’ll own it end to end, from the first prototype through launch, iteration, and beyond.

We value real-time collaboration and prefer candidates located close to Eastern Time, while welcoming exceptional engineers across Pacific Time through ET+2. Regardless of where you are located, your working hours will need to have a majority overlap with ET business hours.

5+ years of fullstack development experience, with 3+ years in TypeScript/Node.js and a modern frontend framework (React preferred)

Fluency with relational databases and SQL

Proven ability to ship production systems, frontend and backend, with high uptime and minimal maintenance burden

Strong product instincts and an eye for good design; you can work from a Figma file but you'll also push back when something doesn't feel right

Comfortable working directly with external partners and customers on requirements gathering, integration, and iterative feature development

MVP mindset: you know how to scope a milestone, ship it, learn from it, and iterate fast

Strong commitment to clean code principles and automated testing

Deep understanding of API design, versioning, documentation, and modern authentication patterns

Excellent communication skills and experience collaborating across product, design, and operations in remote, asynchronous environments

Experience in fast-paced, high-growth startup environments where you've worn many hats

Familiarity with performance profiling, latency reduction, and service-level adherence

Background in designing and operating event-driven architectures

Expertise in Docker, Kubernetes, Prometheus, and Grafana

Passion for building tools, internal or external, that meaningfully improve how people work with money
