* 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
