- Enthusiastic drivers. We need proactive people that can fully own projects and get them done, and know to get help when needed. "Are we there yet?" is the wrong question.
- Optimistic problem solvers. Things get hard here sometimes, whether it's scaling, shipping complex products, handling a stream of support requests, or trying to ship something that touches multiple teams. We need people who won't get disheartened, and will collaborate, iterate, and ship their way out of anything.
- Grown ups. We’re an international bunch of weirdos, but one thing unites us: everyone is kind, considerate, and professional towards each other.This isn't about age or experience, it's about being low-ego, flexible, and respectful.
- Genuine builders. PostHog is full of people who just love building stuff, people who would still be building software even if there wasn't a paycheck at the end. If this sounds like you, we should talk.
What you'll be doing
You won’t be in a typical “keep the lights on” SRE role. The work is about turning a fast-growing, stateful system into a predictable, well-automated platform. (provisioning, scaling, rebalancing, recovery)
That means reducing operational stress, designing safe automation for traffic-heavy workloads, and building the tooling and patterns that let the system scale without scaling human effort.
You'll work on the kind of problems that only show up at large scale (petabytes of data, thousands of cores, constant ingestion) across a multi-region, multi-account AWS platform running many services on Kubernetes.
- Operating EKS clusters across several environments with Karpenter autoscaling, Cilium networking, and ArgoCD-driven GitOps deployments
- Managing and evolving a multi AWS account organization, provisioning, networking, access control, and cross-account connectivity
- Maintaining the Terraform/Terragrunt IaC platform - modules, automated plan-on-PR / apply-on-merge pipelines, and safe patterns for shared infrastructure
- Improving operational tooling around deploys, schema changes, backups, restores, and incident response
- Reducing operational load by identifying repeat pain points and eliminating them through code and self-healing automation
- Optimizing cloud spend as you go
- Participating in on-call and incident response, with a strong focus on making incidents rarer over time
You'll have room to design and automate, not just respond to alerts. You should join this team if you like deep ownership of production systems and enjoy building the platform layer that everything else runs on.
