Software Engineer, Infrastructure
San Francisco, New York City$260k - $300kFull-timePosted 6mo ago
About the role
Infrastructure Engineers at Cognition build the systems that everything else runs on, enabling Devin, Windsurf, and related platform components to operate at scale with reliability and real-time developer tooling.
Responsibilities
- Own agent execution infrastructure: Design and operate the sandboxed compute environments that power Devin's task execution, including VM orchestration, container management, resource scheduling, and isolation at scale.
- Build and maintain the developer platform: Create the internal infrastructure that Cognition engineers depend on every day: CI/CD pipelines, deployment systems, developer tooling, and the abstractions that let product teams ship fast.
- Drive reliability and observability: Define SLOs, build monitoring and alerting systems, lead incident response, and close the loop on postmortems so the same failure never happens twice.
- Scale with the product: Anticipate capacity and architecture needs before they become bottlenecks; make deliberate infrastructure investments that stay ahead of product growth.
- Partner across engineering: Work closely with product engineers and researchers to understand what the systems they are building require, and design infrastructure that meets those needs without creating unnecessary complexity.
Qualifications
- Deep systems engineering: Experience designing and operating large-scale distributed infrastructure; strong opinions about reliability, failure modes, and operational excellence.
- Cloud and container expertise: Hands-on proficiency with Kubernetes, cloud platforms (AWS, GCP, or Azure), and infrastructure-as-code tools like Terraform.
- Strong software engineering fundamentals: Proficiency in Python and comfort owning complex systems codebases.
- Observability instincts: Knows how to instrument systems, build meaningful dashboards, and design alerts that surface signal without noise.
- Security and isolation mindset: Experience with sandboxing, network isolation, and secure multi-tenant compute, particularly relevant for agentic workloads running arbitrary code.
- Relevant industry experience: Prior experience at a frontier AI lab, applied AI company, or developer tools company.
- Degree from a top-tier university: BS, MS, or equivalent in Computer Science, Mathematics, Engineering, or related technical discipline from a highly selective program.
