What you will do

• Build and own observability, SLO, error-budget, and burn-rate tracking capabilities using OpenTelemetry and distributed tracing.
• Establish 24/7 operational readiness through automated deployments, blue/green and canary releases, zero-downtime patching, and automated rollback.
• Engineer self-healing and traffic-management capabilities, including auto-remediation and error-budget-gated recovery.
• Design and execute controlled chaos experiments across AWS to identify and address reliability gaps.
• Build CI/CD and automation tools using software engineering practices, including version control, code reviews, and testing.
• Set reliability standards, support architecture and capacity reviews, facilitate blameless incident reviews, and mentor SREs and engineering teams.

Requirements

• Extensive production experience with OpenTelemetry, observability platforms such as Honeycomb, Datadog, Dynatrace, or Grafana, and direct instrumentation of Java or Python services.
• Proven ability to design meaningful SLIs and SLOs, configure multi-window burn-rate alerts, and manage error budgets with development teams.
• Experience building safe CI/CD pipelines with blue/green or canary releases, automated rollback, and DORA metrics.
• Kubernetes is required, together with cloud networking and infrastructure as code; Terraform is preferred. HashiCorp Nomad experience is advantageous.
• Production-quality Java and/or Python development experience and strong knowledge of distributed-system resilience patterns, including circuit breakers, bulkheads, idempotency, graceful degradation, and load shedding.
• Production on-call experience, blameless post-incident review facilitation, chaos engineering, strong troubleshooting, technical communication, and a bias toward automation.

Nice to have

• Experience in financial services, trading platforms, or other high-throughput, low-latency mission-critical environments.
