With human‑centered, healthcare‑relevant, and value‑based solutions, we create new possibilities with data. We provide proof beyond the concept and performance beyond the scope with a focus on efficiencies that transform the lives of those we serve. With a culture driven by purpose, straightforward communication and clinical domain expertise, Commence cuts straight to better care.

• Design, implement, and own observability infrastructure including metrics, logging, tracing, and alerting across distributed systems.
• Define and enforce SLOs, SLIs, and error budgets in partnership with product and engineering teams.
• Lead incident response: triage, coordinate remediation, conduct blameless post‑mortems, and drive systemic fixes.
• Build and maintain CI/CD pipelines that support rapid, safe delivery of changes to production.
• Collaborate with engineering teams on infrastructure changes; able to read, modify, and contribute to existing infrastructure‑as‑code (Terraform or Cloud Formation).
• Design and operate highly available, fault‑tolerant systems—including auto‑scaling, failover, and disaster recovery strategies.
• Reduce operational toil through automation; eliminate manual processes before they become habits.
• Collaborate with software engineers to establish reliability‑first design patterns and review architectures for operational risk.
• Manage Kubernetes or container orchestration environments at scale.
• Ensure systems meet compliance and security requirements, particularly those applicable to healthcare data (HIPAA, SOC 2).
• Provide technical mentorship and guidance to engineers across the organization on reliability practices.
• Participate in on‑call rotation with a commitment to continuously reducing the need for it.

• 7+ years of experience in SRE, platform engineering, or Dev Ops roles.
• Exceptional problem‑solving under pressure—demonstrated track record of diagnosing complex, high‑stakes system failures and building durable solutions.
• Deep hands‑on experience with AWS services including EC2, EKS/ECS, Lambda, RDS, S3, Cloud Watch, and related tooling.
• Familiarity with infrastructure‑as‑code (Terraform or Cloud Formation)—able to contribute to existing configurations.
• Experience designing and operating distributed systems with strict availability and latency requirements.
• Proficiency in at least one scripting or systems language (Python, Go, Bash, or similar) for automation and tooling.
• Experience with container orchestration (Kubernetes, ECS) in production environments.
• Expertise in observability tooling (Open Search, Prometheus/Grafana, or equivalent).
• Hands‑on experience with CI/CD platforms (Git Hub Actions, Jenkins, Circle
  
  CI, or similar).
• Proven ability to define and operationalize SLOs and error budgets.
• Experience with relational and No
  
  SQL databases—performance tuning, replication, and backup strategies.
• Strong working knowledge of networking fundamentals: DNS, load balancing, VPCs, TLS.
• Excellent communication skills—able to translate technical risk into business impact for non‑engineering stakeholders.

• AWS Certifications (Solutions Architect, Dev Ops Engineer, or Sys Ops Administrator).
• Experience in healthcare technology or other regulated industries (HIPAA, SOC 2, FedRAMP).
• Familiarity with chaos engineering practices and tooling.
• Experience with data pipeline reliability (ETL/ELT workflows, streaming systems).
• Exposure to AI/ML infrastructure and the reliability challenges unique to model serving.
• Familiarity with additional cloud platforms (Azure, Google Cloud).
• Contributions to open‑source reliability or infrastructure tooling.
