Senior Software Engineer, Platform Reliability

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.

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.

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.)

Why this role?

• Reliability as a first-class feature : You won't be patching things up after the fact. You'll build the systems that make Asana resilient by design.
• Foundational work : Load shedding, traffic management, ingress/egress – these are the building blocks that protect everything else. You'll own them.
• Strong collaboration, reasonable hours : You'll work closely with infrastructure teams in Warsaw and Reykjavik, making deep collaboration practical without constant timezone gymnastics.
• Room to grow : 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.

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.

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.

This role is based in our Warsaw office with an office-centric hybrid schedule. The standard in-office days are Monday, Tuesday, and Thursday. Most Asanas have the option to work from home on Wednesdays. Working from home on Fridays depends on the type of work you do, and your recruiter can share more about the in-office requirements.

We offer a Contract of Employment (UoP) for our employees in Poland.

What you'll achieve:

• Design and build core platform systems – load shedding, circuit breakers, rate limiting – that protect Asana 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 mu
