Job Description:

This role is for a software engineer working on Codex, with a specific focus on enabling team-scale adoption across a wide spectrum of environments, from internal teams at OpenAI to external customers ranging from startups to large enterprises. You’ll work directly with customers, Go To Market (GTM) teams, and other engineers and researchers across Codex and OpenAI. You will turn diverse team requirements into products that scale across organizations. The role bridges what teams with Codex’s capabilities, ensuring that they are robust, repeatable, and deeply aligned with how developers work in real-world environments. You’ll own systems end-to-end (architecture, implementation, production operations) with a strong bias for both quality and velocity.

Job Responsibility:

  • Ship fundamental capabilities including analytics dashboards and APIs, compliance and audit surfaces, workspace RBAC and admin controls, managed configuration and constraints, and rate limits, usage, and pricing primitives for teams
  • Design and build robust, full-stack services and APIs that power Codex across surfaces (web/app, CLI/local, IDEs, CI/CD) with strong observability, reliability, and security
  • Enable standardized team deployments by building team configuration packaging and distribution patterns
  • Integrate with enterprise identity and governance systems (e.g., SSO/SAML/OIDC, SCIM, RBAC, policy enforcement), and build data-access patterns that are secure, performant, and compliant for large customers
  • Partner with GTM to work hands-on with teams through deep engagements to accelerate adoption, iterate rapidly, and translate real-world feedback into scalable product and platform improvements

Requirements:

  • Strong software engineering fundamentals and experience turning ideas into productionized systems, thinking holistically about speed, performance, and user experience
  • Proficient in one or more backend languages (e.g., Python, Go, Rust) and distributed systems concepts, with a focus on reliability, observability, and security
  • Experience building cross-cutting platform capabilities
  • Experience with team/enterprise foundations such as identity and access (SAML/OIDC), SCIM, RBAC, audit/compliance logging, policy enforcement, and data governance controls
  • Experience building developer tools and workflows (CLI/IDE/SDK), automation systems (triggers/scheduling), or integration platforms
  • Enjoy working directly with users/customers and translating diverse requirements into scalable implementations
  • Enjoy 0 -> 1 environments, can navigate ambiguity, and bring crisp product thinking to technical trade-offs
