Our client is on a mission to redefine how humans and AI collaborate. By reimagining digital productivity, they're empowering millions of users to unlock new dimensions of creativity, learning, and performance.
They're building a world-class platform used globally - and now they're hiring their first Senior Chaos Engineer to help scale with resilience.
Why This Role Matters
Do you love breaking things on purpose - and making systems stronger because of it? This is a rare opportunity to define and lead chaos engineering from the ground up. You'll design controlled failure scenarios, uncover hidden risks, and build a culture of reliability through experimentation and learning. What You'll Be Doing
- Define the chaos engineering strategy, tooling, safety practices, and roadmap
- Design fault injection experiments across mobile and backend systems
- Simulate real-world issues: latency spikes, outages, cascading failures, resource exhaustion
- Build tooling to automate experiments and improve observability
- Set guardrails and blast radius controls to ensure safe, reversible testing
- Collaborate with engineering teams to stress-test critical flows and assumptions
- Facilitate resilience drills and chaos game days
- Document findings, translate insights into improvements, and influence engineering practices
- Mentor others and help grow the chaos engineering function
Who You Are
- Proven experience with chaos engineering or fault injection in distributed systems
- Strong Swift skills and understanding of iOS platforms and mobile networking
- Deep knowledge of resilience patterns (circuit breakers, bulkheads, retries, etc.)
- Experience with incident postmortems, war games, or reliability reviews
- Comfortable scripting and building tools to automate chaos experiments
- Scientific mindset: hypothesis-driven, curious, and edge-case obsessed
- Excited to build a program from scratch - not just join one
What's In It For You
- Remote-friendly & flexible working hours
- Medical insurance for you and your dependents
- Generous annual leave
- Meaningful equity in a profitable tech startup
- Budget for home office setup, training, and wellness
- Annual company offsite
- Fantastic maternity/paternity packages
- Visa sponsorship and relocation support
