• 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.
• 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.)
• Build 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.
• Build developer tools as products, instead of loose scripts. Evolve our in-house local development environment, BIBEs (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.
• Reduce 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.
• Keep 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.
• Improve 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.
• Partner 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.
