Senior Software Engineer, Platform Reliability

About the Role

We're looking for a Senior Platform Reliability Engineer who brings strong software engineering skills and a deep understanding of system behavior under load and stress. This role is a good fit for someone who wants to own reliability as a first-class concern – building the foundational systems that protect the company's platform, not just responding when things go wrong.

You'll build core platform systems like load shedding, rate limiting, circuit breakers, and traffic controls that protect the company under real-world load. This is deep, cross-cutting work that shapes stability and performance of our entire infrastructure – and you'll partner closely with other platform teams to make reliability something that's built in, not bolted on.

Our tech stack includes: AWS, Kubernetes (EKS), CloudFront, Istio, Cilium,  MySQL (RDS), OpenSearch, DynamoDB, Redis, Terraform, Datadog, TypeScript, Scala, Go, and Python. (Yeah, we know this sounds like buzzword bingo – but we want this post to actually show up in your searches.)

Responsibilities

• Design and build core platform systems – load shedding, circuit breakers, rate limiting – that protect the company at scale.

• Own critical platform concerns like ingress and egress, shaping how traffic flows through our systems.

• Define stable interfaces and libraries that other platform teams build on.

• Lead end-to-end projects, from scoping and design through to rollout, working across multiple platform teams.

• Partner with other infrastructure teams to embed reliability into the company's architecture – not as an afterthought, but as a core design constraint.

• Debug hard problems across the stack. When something breaks in a way that matters, you'll be the person who figures out why and makes sure it doesn't happen again.

• Share knowledge through code reviews, design discussions, and mentorship.

Requirements

• Strong software engineering background – you're comfortable writing production code and designing systems. We use Go, Python, Scala, and TypeScript, but we care more about engineering fundamentals than specific language experience.

• 5+ years of experience building and operating backend systems at scale.

• Familiarity with distributed systems patterns – you've thought about things like backpressure, graceful degradation, and capacity planning.

• Experience with major cloud platforms (AWS, GCP, or Azure), Terraform, and monitoring tooling like Datadog or similar.

• Experience defining and working within explicit reliability and performance targets for production systems.

• Clear communicator and strong collaborator – you're comfortable navigating trade-offs with other platform and infrastructure teams.

• Demonstrates curiosity about AI tools and emerging technologies, with a willingness to learn and leverage them to enhance productivity, collaboration, or decision-making
