We're hiring a Senior Infrastructure Engineer at Buffer
Job Description
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.
Keeping the lights on at a higher bar. 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.
Modernizing the foundation. 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.
Responsibilities
- You've worked as an Infrastructure Engineer, SRE, or in a DevOps or platform engineering role, on systems real people depended on.
- You've run production Kubernetes. You've authored and maintained Helm charts, tuned autoscaling and resource requests, and kept it standing under real traffic.
- You know AWS and Terraform well. You default to modules, keep the code readable and adaptable, and can say what happens when a plan touches something load-bearing.
- You've operated production CI/CD and GitOps, including a rollback path you'd trust when something breaks in production.
- You've carried the pager for something you built. You've run an incident, written the follow-up, and turned off the alert nobody trusted anymore.
- You've built internal developer tooling. CLIs, dev environments, per-PR environments. You've felt the difference between something that ships and something that gets used.
- You thrive in remote, async environments. You're clear in your thinking and generous with context.
- Slow and flaky bothers you. You ship something rough teammates can react to, then keep going until the whole class of problem is gone, not just the one bug in the ticket.
- You're fluent with modern AI tools. You use them to debug, document, and reduce toil, not just to generate code.
- You make pragmatic build-vs-buy calls, you weigh what things cost to run, and you revisit both when conditions change. You'd rather invest in fundamentals that compound than chase the newest tool.
- You have a personal stake in making and publishing things. What that looks like is yours to choose: writing, video, code, photos, music, a niche account with twelve followers. Audience size is not the point. We're a Team of Creators, and infra gets better the closer it sits to that experience.
