Senior Site Reliability Engineer

What You’ll Do

Reliability Engineering & System Ownership

• Define and implement SLIs, SLOs, and error budgets across core services.
• Own production system health: uptime, latency, and availability targets.
• Improve system resilience through proactive reliability work.
• Find and mitigate single points of failure across distributed systems.

Production Operations & Incident Response

• Take part in and improve on-call rotations and incident response.
• Lead incident triage, mitigation, and resolution in real time.
• Run blameless postmortems and follow through on action items.
• Build tooling and automation to cut MTTR (Mean Time to Recovery).

Observability & System Insight

• Design and evolve observability across metrics, logs, and distributed tracing (OpenTelemetry), using tools like Datadog, CloudWatch, Grafana, and Sentry.
• Improve signal quality to cut noise and alert fatigue.
• Build dashboards and alerts that reflect real system health and user impact.
• Use observability data to drive performance and reliability improvements.

Performance & Scalability

• Analyze system performance under load and find bottlenecks.
• Optimize latency, throughput, and resource use across serverless (AWS Lambda), containerized services (ECS), and data systems (Aurora Postgres, ClickHouse).
• Partner with engineering teams to improve system efficiency and scaling behavior.

Automation & Reliability Tooling

• Build automation that eliminates repetitive operational work.
• Improve deployment safety through reliability checks and safeguards.
• Contribute to CI/CD pipelines (GitHub Actions) with a focus on stability.
• Build tools for incident response, debugging, and capacity planning.

Security, Compliance & Operational Maturity

• Partner with security and compliance to keep systems meeting operational standards.
• Support audit readiness and reliability-related compliance requirements (Vanta).
• Integrate monitoring and alerting into security and SIEM workflows.
• Help mature operational practices across engineering.

You May Be a Fit If

• You've spent 5+ years in Site Reliability Engineering, SRE-adjacent roles, or production infrastructure.
• You've operated and debugged distributed systems in production.
• You have hands-on experience with observability tooling (Datadog, Grafana, OpenTelemetry, or similar), incident response and on-call practices, and performance and reliability debugging.
• You've defined and worked with SLOs, SLIs, and error budgets.
• You're familiar with AWS environments, serverless and container-based architectures, and Postgres or similar relational databases.
• You can write code or scripts (Python, Bash, etc.) for automation and tooling.
• You think in systems and reason clearly about failure modes.

Bonus points for

• experience in high-growth or high-scale environments
• background in regulated industries like healthcare or fintech
• experience with ClickHouse or analytical systems at scale
• familiarity with chaos engineering or load testing
• exposure to ML infrastructure or data platforms
