Job summary

Affim is seeking a seasoned Engineering Manager to lead the Resilience Engineering team, focused on production load testing and chaos engineering to ensure safety and reliability of critical systems.

You’ll mentor engineers and partner with infrastructure, product, and security leaders to embed resilience validation into the SDLC, establishing guardrails and end-to-end observability for all experiments.

Qualifications

• Proven experience leading engineering teams in reliability, infrastructure, or distributed systems.
• Hands-on experience with production load testing, chaos engineering, or large-scale system validation.
• Experience with leveraging a chaos engineering vendor such as Gremlin, Harness, or something similar.
• Strong understanding of failure modes in distributed systems, including latency, partial failure, and cascading outages.
• Experience building or operating systems with strong safety guarantees (isolation, rate limiting, guardrails, auditability).
• Familiarity with cloud-native environments (AWS, Kubernetes) and observability tooling.
• Strong programming background (e.g., Python, Kotlin, Java, or similar).
• Excellent problem-solving skills and the ability to balance long-term resilience investments with immediate business needs.
• Strong communication and leadership skills, with a track record of influencing engineering practices across teams.
• This position requires either equivalent practical experience or a Bachelor’s degree in a related field.

Responsibilities

• Define and drive the vision for resilience engineering at Affim, with a focus on production load testing and chaos engineering as first‑class engineering practices.
• Lead and mentor a team of engineers building platforms and tooling for safe production experimentation.
• Partner with infrastructure, product, and security leadership to embed resilience validation into the software development lifecycle.
• Establish best practices for safely testing system limits and failure scenarios in production.
• Own the design and evolution of platforms that enable safe, controlled production load testing and fault injection.
• Ensure strong safeguards are in place, including isolation boundaries, approval workflows, and automated rollback mechanisms to protect real users.
• Build systems that provide end-to-end observability, traceability, and auditability for all resilience experiments.
• Drive reliability improvements by systematically identifying weaknesses through load testing and chaos experiments.
• Establish monitoring, alerting, and incident response practices tailored to proactive resilience validation.
