Senior Software Engineer, Platform Reliability

<p>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 Asana's platform, not just responding when things go wrong.</p> <p>You'll build core platform systems like load shedding, rate limiting, circuit breakers, and traffic controls that protect Asana 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.</p> <p>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.)</p> <p></p> <p>Why this role?</p> <ul> <li><strong>Reliability as a first-class feature</strong>: You won't be patching things up after the fact. You'll build the systems that make Asana resilient by design.</li> <li><strong>Foundational work</strong>: Load shedding, traffic management, ingress/egress – these are the building blocks that protect everything else. You'll own them.</li> <li><strong>Strong collaboration, reasonable hours</strong>: You'll work closely with infrastructure teams in Warsaw and Reykjavik, making deep collaboration practical without constant timezone gymnastics.</li> <li><strong>Room to grow</strong>: This is a new team, and you'll help shape what Platform Reliability Engineering looks like at Asana – whether that means leading projects, mentoring others, or defining our technical direction.</li> </ul> <p>In this role, success means shipping systems that other teams rely on by default – because they make the platform safer, not because they're mandatory.</p> <p></p> <p>We're especially interested in people who think like backend engineers but obsess over failure modes, capacity planning, and building systems that degrade gracefully under pressure.</p> <p>This role is based in our Warsaw office with an office-centric hybrid schedule – in-office days are Monday, Tuesday, and Thursday. </p> <p>We offer a Contract of Employment (UoP) for our employees in Poland.</p> <p><strong>What you'll achieve:</strong></p> <ul> <li>Design and build core platform systems – load shedding, circuit breakers, rate limiting – that protect Asana at scale.</li> <li>Own critical platform concerns like ingress and egress, shaping how traffic flows through our systems.</li> <li>Define stable interfaces and libraries that other platform teams build on.</li> <li>Lead end-to-end projects, from scoping and design through to rollout, working across multiple platform teams.</li> <li>Partner with other infrastructure teams to embed reliability into Asana's architecture – not as an afterthought, but as a core design constraint.</li> <li>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.</li> <li>Share knowledge through code reviews, design discussions, and mentorship.</li> </ul> <p><strong>About you:</strong></p> <ul> <li>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.</li> <li>5+ years of experience building and operating backend systems at scale.</li> <li>Familiarity with distributed systems patterns – you've thought about things like backpressure, graceful degradation, and capacity planning.</li> <li>Experience with major cloud platforms (AWS, GCP, or Azure), Terraform, and monitoring tooling like Datadog or similar.</li> <li>Ex ...
