• Plan, enable, and drive Chaos initiatives across Engineering teams, based upon internal priorities.
• Develop, deploy and manage tools to systematically run chaos experiments and measure impact.
• Enjoy working on, and gaining a deep understanding of, large‑scale distributed systems.
• Study the problems in the software resilience, operational, and delivery spaces.
• Extend our entire backend to enable Chaos Engineering techniques in the system.
• Observe running systems, and determine/prioritize innovative ways to disrupt them.

About you

• You have 6+ years of relevant software development industry experience building and operating scalable, fault‑tolerant, distributed systems.
• Software development experience in Go, C/C++, Java, or similar.
• Experience with concurrency, multithreading, and the deployment of distributed system architectures.

• You have excellent communication skills and the ability to work well within a team and across engineering teams.
• You are a strong problem solver and have solid production debugging skills.
• You are passionate about efficiency, availability, scalability, and data governance.
• You thrive in a fast‑paced environment, and see yourself as a partner with the business with a shared goal of moving the business forward.
