We create social media and brand-building software for small businesses, creators, and individuals. Our mission is to provide essential tools to help small businesses get off the ground and grow. Through exceptional customer service and uplifting content, we help our customers believe they can succeed and do good along the way.

Buffer is a fully distributed team, and we’ve always aimed to do things a little differently at Buffer. Since the early days, we’ve focused on building one of the most unique and fulfilling workplaces by rethinking a lot of traditional practices. We also default to transparency, so you can read all about our metrics, and our successes and failures along the way on our 

, and we hire and work from all over the world. We strive to create a diverse and inclusive work environment, and we are building a culture where underrepresented groups are welcome and can flourish. Please note that we do travel to work together in person once or twice per year, and those events are highly encouraged to build deeper connections among our small team.

As you get to know Buffer and consider joining the journey, you can learn more about Buffer on our 

 page. Still curious to learn more about the experience on the Buffer team? Feel free to read more from 

 as they share their first experiences with Buffer, as well as from 

, who captured why she still calls Buffer home after 8+ years. 

As Buffer's next Senior Infrastructure Engineer, you'll join two seasoned Infrastructure Engineers on a small, deliberate, high-leverage team. Together, you'll run the platform that lets every Buffer engineer ship, and that indirectly lets millions of creators publish, grow, and earn a living on the social web. When our infrastructure is fast and reliable, creators get features sooner and outages less often.

You'll own a meaningful slice of three shifts the team is making.

 You'll make our CI/CD pipelines faster and even more anti-fragile, ship boring deploys, and turn each incident into a new lesson rather than a repeat.

 Buffer is not new, but our Infra is in continuous improvement. From deploying KEDA and Argo Rollouts to improving our signal-to-noise ratio in monitoring, there is plenty to do. One cannot talk about modernization without mentioning AI. We're already leaning on it for investigations and boilerplate, and want to bring it deeper into our day-to-day.

Treating engineers across Buffer as customers.

 You'll evolve the developer tooling that makes the inner loop fast, with documentation that holds up at 2am or when consumed by an agent.

We're remote-first with a preference for at least 4 hours of overlap with EMEA time zones, but we're open to strong candidates anywhere in the world.

It's an exciting time to join. Buffer is a profitable, 15-year-old company innovating at the edge of AI-assisted development, and there's lots of impactful work to do. 

, the Infrastructure Engineering Manager.

, who have helped build the infrastructure we run on since the beginning of Buffer. We're looking to round out the team with someone who sits between infra and developer experience: deep infra expertise paired with an infra-as-a-product mindset.

You'll also work daily with all of EPD (Buffer's unified Engineering, Product, and Design team). EPD are the internal customers of the platform you maintain, and they contribute to it too.

 the day-to-day reliability of our production platform. Keep EKS, ArgoCD, and the AWS surface area boring, tune autoscaling so the system adjusts well under load, and approach incident response in a way that each incident teaches us something new instead of repeating itself. (On-call is distributed across all engineers at Buffer, a week-long shift roughly once a quarter.)

 progressive delivery into something the rest of engineering trusts. Implement Argo Rollouts with clean rollback paths, so the time between "this deploy is bad" and "this deploy is reverted" measures in seconds to minutes.

 developer tools as products, instead of loose scripts. Evolve our in-house local development environment, 

 (Buffer Isolated Build Environments, per-PR full-stack staging deployments), and our CLI tooling so the inner loop is fast, frictionless, and parallel-friendly for AI agents. Measure adoption, talk to your users, iterate.

 operational toil with AI. Automate low-risk workflows end-to-end so the team spends its time on the hard problems, not the repeat ones. AI doesn't touch infrastructure directly, it speeds up the humans who do.

 the stack current. Drive lifecycle upgrades: application runtimes (Node.js, Python), Kubernetes, EKS, Helm versions, and the Terraform-managed surface area. Own infra-side security vulnerabilities.

 the economics of our platform. Lead visibility work on Datadog, AWS rightsizing, and log filters so observability and cloud spend grow slower than the company does.

with EPD on the platform they build on. Raise the documentation bar with the team, carry your share of weekly security work (dependency and vulnerability management is everyone's job), and help the infra team grow toward shared ownership and fewer single-person dependencies.

You've worked as an Infrastructure Engineer, SRE, "DevOps" engineer, or adjacent role for long enough to be considered senior.

You have hands-on experience operating production Kubernetes at scale on a managed offering (GKE, EKS, AKS), including authoring and maintaining Helm charts, and you're fluent with autoscaling primitives driving KEDA and the cluster auto scaler.

You have AWS depth across IAM, EC2, S3, SQS, ECR, and ALBs. You may have also used Cloudflare (WAF, Workers, etc.) and GCP (BigQuery).

You have strong Terraform skills. You default to modules for structure, and keep the code adaptable, readable, and self-contained. Bonus points if you contributed an OSS module.

You've operated production CI/CD with GitHub Actions (or equivalent) and GitOps via ArgoCD (or similar). You've authored ArgoCD pipelines and Helm configuration yourself, including canary or progressive delivery systems you'd trust to roll back safely.

You've built internal developer tools (CLIs, dev environments, per-PR environments) and you think about them as products with users, not scripts.

You have a track record of pragmatic build-vs-buy decisions on infrastructure tooling. You can defend a choice and revisit it when conditions change.

You've worked with DataDog, Sentry, or similar observability stacks, and you design logs and metrics with cost in mind. You know observability and cloud spend can grow faster than the company if no one is watching.

You're comfortable with the Cloudflare across Workers, Zero Trust, DNS, and the rest of their platform.

You read and modify TypeScript or Node services well enough to upgrade runtimes and unblock teams (legacy PHP and Python show up too).

You're fluent with modern AI tools. You use them to debug, document, and reduce toil, not just to generate code, and you bring those patterns into how infra runs.

You're proactive and you follow through. You spot what needs doing before you're asked, and you close the loop without being chased.

You turn ambiguity into proofs of concept. You take fuzzy asks, ship something rough teammates can react to, and iterate with them until it lands.

You thrive in remote, asynchronous environments. You're clear in your thinking, generous with context. 

You don't wait for perfect information to start, and you don't wait for perfect to ship. 

You see infra as a force multiplier for engineering, not a gatekeeper.

You care about Buffer's customers. When things are slow for them it's painful for you to see. When errors are flaky you find the root cause and try to eliminate the entire class of problem, because you see the system, not the bug.

You care about performance. If it's too slow to use, it shouldn't exist. You'd rather make it fast than work around it.

You're a generalist engineer with strong spikes: T-shaped folks with depth in infrastructure and the flexibility to pivot as priorities shift. 

You create, not just consume. Open source contributions, a technical blog, conference talks, side projects, or active accounts on the platforms Buffer serves, your pick. We're a Team of Creators ourselves, and the closer infra is to the creator's experience, the better the platform becomes.

You think about infrastructure as a platform with users. APIs, SDKs, CLIs, MCP servers, or developer-facing tooling you've shipped where adoption, not just deployment, was the success metric. You've felt the difference between code that ships and code that gets used.

You play the long game. You'd rather invest in compounding fundamentals than chase the platform-of-the-month.

Bonus points if you're already a Buffer user or familiar with social media management tools.

 AWS, GCP, Cloudflare. Products you'll find in use here: EC2, EKS, S3, SQS, SNS, ECR, IAM, ALB, BigQuery, mostly managed in Terraform.

 Kubernetes on EKS, Helm for charting, KEDA for SQS-driven autoscaling. ArgoCD for deploys from git. An in-house canary system that we want to augment with Argo Rollouts. BIBEs and frontend branch deployments for per-PR previews.

 GitHub Actions, with self-hosted AWS runners (including KVM-capable instances for Android UI tests). Our monorepo is the consolidation target, and we're moving more services into it over time.

 Datadog for logs, metrics, APM, and spans. Sentry for errors. 

 (and a bit of PagerDuty) for the incident lifecycle and postmortems.

 Cloudflare across Workers, Zero Trust, DNS, and more. CloudFront for AWS-side distribution. VPC peering for cross-account connectivity. OctoDNS for DNS-as-code.

 MongoDB fronted by GraphQL, Elasticsearch, Redis.

 Hermes (our in-house environment that mirrors production) running in OrbStack, pre-built production containers from ECR.

 Node.js and TypeScript across most services, Python in selected services and tooling, and PHP for legacy services that are still load-bearing and being gradually replaced.
