Site Reliability Engineer (US - Pacific time)

PostHog, Remote (US)

What you will do

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.

What you need

Who we're looking for

We’re looking for people (in the US – Pacific timezone) that like deep ownership of production systems, people that are not afraid of working with stateful infrastructure and love working in AWS, VMs, automation, and making messy systems reliable.

In general we seek SRE’s who are

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 https://posthog.com/handbook/company/grown-ups, 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.

Requirements

Deep hands-on experience with Kubernetes in production (EKS preferred). You've debugged node pressure, networking issues, and deployment failures at scale (thousands of nodes)
Strong experience operating production infrastructure on AWS. Not just one account, but understanding organizational boundaries, IAM, and networking between many
Experience automating infrastructure using Terraform or Terragrunt at scale, including module design and state management
Solid understanding of Linux systems (disk, memory, networking, failure modes)
Experience supporting stateful systems (databases, queues, storage systems, etc.)
Ability to debug and reason about performance and reliability issues in production
You're comfortable owning systems end-to-end, including on-call responsibilities

You don't need to be an expert in every system we run on day one. But you do need to enjoy owning complex infrastructure and learning how the pieces fit together.
