Oscar Health is seeking a Senior Software Engineer to join the Core Technology team, which builds and maintains the foundational platform supporting all Oscar engineering. The role focuses on cloud infrastructure and site reliability engineering (SRE), with responsibility for architecting resilient systems on AWS/GCP, Terraform, and Kubernetes.
You will become a domain expert in DevOps, site reliability, and cloud best practices. Key responsibilities include leading the planning and execution of complex technical projects across multiple teams, mentoring junior engineers, and independently owning large technology capabilities. You'll work with product managers and cross-functional partners to solve challenging infrastructure problems, actively identify and reduce failure domains, and design resilient systems that minimize business impact during outages.
The role emphasizes technical leadership without direct people management—you'll guide development of Service-Level Objectives (SLOs), drive technical roadmap prioritization, and own medium-to-large infrastructure projects from design through completion. You'll also facilitate cross-team collaboration and contribute to organization-wide initiatives.
Required qualifications include 6+ years of professional software engineering experience with increasingly impactful accomplishments, demonstrated expertise in leading technical contributions, experience mentoring junior engineers, and a track record as a major contributor to cross-pod or cross-company deliverables. You should set and enforce standards for stable, correct, and maintainable code.
Bonus qualifications include deep expertise in AWS or GCP production environments at scale, advanced experience with Terraform or similar Infrastructure as Code tools, proven track record with Kubernetes and ArgoCD, strong SRE background including SLOs and incident management, experience building CI/CD pipelines via GitHub Actions, proficiency with observability tools like Prometheus or Grafana, knowledge of cloud-native security and service mesh technologies, programming capability in at least one language, and a B.S. in Computer Science or related field.
