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
