Lead Infrastructure Engineer
About The Position
Onos Health is seeking an experienced infrastructure engineer to become their first dedicated platform hire and the owner of the infrastructure the Onos platform runs on. Onos is in production with the nation's largest health plans, which comes with contractual uptime SLAs, disaster recovery commitments, and a security bar (SOC 2, HIPAA) that clients audit. This role will own infrastructure end to end. The role involves leveraging AI coding agents to specify work and direct them, making prior tech lead or engineering management experience directly transferable. As an early team member, this role will set the patterns for future platform engineers at Onos.
Requirements
- Deep AWS experience — you've owned production cloud infrastructure end to end (IAM, networking, KMS, containers, managed databases)
- Strong Terraform/IaC and CI/CD expertise; you treat pipelines and environments as products with users
- Taken a company through at least one SOC 2 (or HITRUST/ISO 27001) audit cycle with your hands on the technical controls
- SRE fundamentals — SLOs, incident management, DR design — with the judgment to right-size reliability for a startup with enterprise contracts
- Prior experience leading engineering teams as a tech lead or engineering manager — you can break down ambiguous goals, delegate (to humans or AI agents), and communicate crisply with non-technical stakeholders
- Customer obsessed and motivated to make an impact in the healthcare space
Nice To Haves
- Significant experience in healthcare or another regulated industry, with HIPAA fluency
- Policy-as-code (OPA, Kyverno) or compliance automation (e.g., Vanta, Drata) experience
- Been the first infrastructure hire, or helped found or lead a platform team
- Built internal tooling or infrastructure for LLM/agent systems
Responsibilities
- Own our availability, disaster recovery, and backup commitments to enterprise clients — multi-region failover architecture and the recovery exercises that prove it
- Stand up production monitoring, alerting, SLOs, and our on-call rotation and incident response process
- Own the technical controls behind SOC 2 and HIPAA: cloud security posture (AWS org guardrails, IAM least-privilege, KMS/encryption), vulnerability remediation, and continuous audit evidence through Vanta, with a path toward HITRUST
- Build the CI/CD pipelines, Terraform/IaC foundations, preview environments, and test infrastructure the whole team ships on
- Build the guardrails that let AI coding agents ship safely — policy-as-code, deploy verification, and agent-operated operations tooling
- Set the strategy and operating rhythm for platform work: priorities, status, and what we deliberately defer
Benefits
- Hybrid arrangement: 3 days/week at San Francisco office (Financial District)
- Unlimited vacation policy
- Paid parental leave
- Medical, dental, and vision insurance
- Pre-tax commuter benefits
- 401(k)
- Significant equity as an early employee
- Direct mentorship from experienced founders
- Ground-floor opportunity to help build a team and culture
- Regular team events and offsites
- Company-provided equipment and home office setup
