Responsibilities
Shape the evolution of Codex itself by identifying how teams actually use (and break) AI-powered software engineering, and driving changes across product, infrastructure, and model behavior to make Codex a truly reliable teammate for organizations
Build the core team and enterprise primitives that make Codex usable at scale including container orchestration, virtual machine provisioning/configuration, execution sandboxes, shared block storage, RBAC, admin and audit surfaces, usage, rate limits and pricing controls, managed configuration and constraints, and analytics that give teams and operators deep visibility into how Codex is being used
Design and own secure, observable, full-stack systems that power Codex across web, IDEs, CLI, and CI/CD, integrating with enterprise identity and governance systems (SSO/SAML/OIDC, SCIM, policy enforcement) and building data-access patterns that are performant, compliant, and trustworthy
Lead real-world deployments and launches by working directly with customers and GTM to roll Codex out across teams, using live usage and operational signals to rapidly iterate and turn messy, real-world feedback into scalable product and platform improvements
Qualification
Required
Strong software engineering fundamentals and experience turning ideas into production-grade large-scale distributed systems, thinking holistically about balancing speed, performance, costs, and user experience
Experience using AI-powered/agentic software development tools and familiarity with their strengths/weaknesses
Experience with orchestration of scaled containerization and/or virtualization systems (e.g. Kubernetes, OCI)
Proficiency in one or more backend languages (e.g. Python, Go, Rust) and concurrency/distributed systems concepts, with a focus on reliability, observability, and security
Enjoy building cross-cutting platform capabilities that unlock product velocity, and comfortable working across services, APIs, and end-user product surfaces
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 that connect products to a broader ecosystem of tools
Enjoy working directly with users/customers (or alongside GTM/solutions teams), and can translate messy, diverse requirements into opinionated implementations that scale across many teams
Enjoy 0 -> 1 environments, can navigate ambiguity, and bring crisp product thinking to technical trade-offs
