Responsibilities

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.
Who you'll work with
Day-to-day you'll work closely with Peter and Steven, 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.
What you'll be working on
Own 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.)
