Sr Site Reliability Engineer

Sr Site Reliability Engineer (SRE)

Commence is looking for a Senior Site Reliability Engineer to own the reliability, scalability, and operational health of its mission-critical healthcare data platform.

Responsibilities

• Own reliability across the lifecycle: embed reliability as a first-class concern from architecture through deployment.
• Design and operate observability: implement metrics, logging, tracing, and alerting for distributed systems.
• Define reliability targets: establish and enforce SLOs/SLIs and error budgets with product and engineering teams.
• Lead incident response: triage, coordinate remediation, run blameless post-mortems, and drive systemic fixes.
• Build CI/CD pipelines to enable rapid and safe production releases.
• Partner on infrastructure changes and contribute to existing Infrastructure-as-Code (Terraform or CloudFormation).
• Design and operate resilient systems: highly available, fault-tolerant architecture with auto-scaling, failover, and disaster recovery.
• Reduce operational toil via automation and elimination of manual processes.
• Review architectures for operational risk and help establish reliability-first design patterns.
• Operate container orchestration at scale (Kubernetes/container platforms).
• Ensure compliance and security requirements for healthcare data (e.g., HIPAA, SOC 2).
• Mentor engineers on reliability practices.
• Participate in on-call rotation with a continuous focus on reducing the need for it.

Requirements

• 7+ years in SRE, platform engineering, or DevOps.
• Proven ability to solve complex, high-stakes system failures under pressure.
• Deep hands-on experience with AWS services: EC2, EKS/ECS, Lambda, RDS, S3, CloudWatch.
• Familiar with Terraform or CloudFormation to contribute to existing IaC.
• Experience designing/operating distributed systems with strict availability/latency requirements.
• Proficiency in at least one scripting/systems language: Python, Go, Bash (or similar).
• Production experience with container orchestration (Kubernetes, ECS).
• Observability tooling experience: OpenSearch, Prometheus/Grafana (or equivalents).
• CI/CD experience with platforms such as GitHub Actions, Jenkins, CircleCI.
• Ability to define and operationalize SLOs and error budgets.
• Experience with relational and NoSQL databases (performance tuning, replication, backup strategies).
• Strong networking fundamentals (DNS, load balancing, VPCs, TLS).
• Excellent communication skills to translate technical risk into business impact.

Nice-to-have / Additional Requirements

• AWS Certifications (exact requirements appear cut off in the provided text).
