Senior Site Reliability Engineer

Mission Alignment: Drive MX reliability via prevention engineering, AI automation, and SRE excellence

Key Responsibilities

• Incident Response (Hands-On): Triage and mitigate production incidents using observability for Golden Signals (latency, traffic, errors, saturation). Identify root issues in MX architecture (e.g., database sharding, webhook failures), escalating just-in-time under unified command to minimize MTTR <1h.

• Incident Response: Drive a coordinated response to an active incident, ensuring that communication is clear, roles are assigned, and the incident is mitigated efficiently and safely

• Analysis & Pattern Recognition: Analyze incidents, postmortems, and architecture (e.g., RMQ overflows) to identify recurring issues. Develop knowledge bases and AI-driven early warning systems for proactive prevention.

• Prevention Engineering: Identify incident trends and drive projects to prevent repeated incidents cross-org amongst multiple engineering teams. Identify and implement mitigation mechanisms, improve observability, alerting, and runbooks.

• Perform on-call rotations; enforce priority matrix; lead RCAs with client-readable, legal-approved outputs.

• Cross-functional collaboration to enhance observability (e.g., black-box probes) and reduce technical debt.

Required Qualifications

• 7+ years SRE/DevOps; 1+ in AI/ML for reliability (e.g., predictive analytics on incident data).

• Proficient in Datadog, Kubernetes, Python/Javascript for AI/automation.

• Experience reducing MTTR/repeats in distributed systems; familiar with SLOs/error budgets.

• BS in CS or equivalent experience; Americas on-call availability.

Preferred Skills

• Datadog/similar experience

• Fintech experience with MX-like architectures

• Google SRE practices: toil elimination, incident management, automation for self-healing.

• Proficiency in JavaScript for frontend observability/tools.

• Golang, Ruby on Rails experience
