Asana

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 multiple platform teams. * Partner with other infrastructure teams to embed reliability into Asana'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. About you: * 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. * 7+ 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 At Asana, we're committed to building teams that include a variety of backgrounds, perspectives, and skills, as this is critical to helping us achieve our mission. If you're interested in this role and don't meet every listed requirement, we still encourage you to apply. Important: This is a software engineering role. If your background is primarily scripting, dashboards, or operational playbooks, this likely isn't a fit. What we offer * Generous, transparent and fair compensation system (base salary and generous Restricted Stock Unit for Asana Inc.)  * Contract of Employment (with 50% tax deductible costs for author’s rights usage for Engineers)  * Health insurance with dental and travel coverage (Lux Med)  * Lunch catering on the days that you work from the office * Career growth budget  * Home office setup budget  * Gym/Fitness card * Fertility healthcare and family-forming support with Carrot * Mental health support in Modern Health * Group life insurance * Holiday allowance * MacBooks with all necessary accessories For this role, the estimated base salary range is between 31,000 - 36,000 PLN gross monthly on the contract of employment (UoP). The actual base salary will vary based on various factors and individual qualifications objectively assessed during the interview process. The listed range above is a guideline, and the base compensation range for this role may be modified. Our total compensation consists of base salary and equity (RSUs).  #LI-Hybrid #LI-KM2 About us Asana is a leading platform for human + AI collaboration.
