Software Engineer, Codex for Teams

Details

About the Team

With Codex we’re building an AI software engineer. One that you can pair with, delegate to, or even ask to take on future tasks proactively. Our team is a fast-moving group within OpenAI, bringing together research, engineering, design, and product. We iteratively build the Codex agent harness and product to get the most out of the model, and we iteratively train the model to be great at complex software engineering tasks.

The Codex team is responsible for building state-of-the-art AI systems that can write code, reason about software, and act as intelligent agents for developers and non-developers alike. We operate across research, engineering, product, and infrastructure; owning the full lifecycle of experimentation, deployment, and iteration on novel coding capabilities.

Codex for Teams builds products and platform capabilities to drive the adoption of Codex in diverse team environments. It is a cross-cutting team that works across the stack to build both delightful product experiences and fundamental platform capabilities. Its customers range from small teams to large enterprises, and our mission is critical to achieving the vision of Codex as a proactive teammate.

About the Role

As we grow, we’re focused on turning Codex from a powerful individual tool into a production-grade teammate for entire organizations. You will work across internal OpenAI teams and external customers, from fast-moving startups to large enterprises, to make it possible to deploy, operate, and trust Codex in increasingly demanding real-world environments.

As Codex’s consumer adoption accelerates, enterprise demand is growing just as quickly and there’s opportunity to continue to drive key workflows, controls, and reliability improvements. This team helps turn messy, real-world team requirements into robust, repeatable, and scalable product and platform capabilities.

You will work directly with a small set of deeply engaged design‑partner customers using their real deployments to surface opportunities, and what’s required for Codex to succeed inside modern engineering organizations. Those insights will drive what you build across product, infrastructure, and deployment patterns for all teams using Codex.

This role owns systems end-to-end: from architecture and implementation to production operations with a strong bias for both quality and velocity.

Responsibilities

• Shape the evolution of Codex 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 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 the Go To Market team (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.

Requirements

• Strong software engineering fundamentals and experience turning ideas into productionized systems, thinking holistically about speed, performance, and user experience.
• Proficiency 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 that unlock product velocity; 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 the ability to translate messy, diverse requirements into opinionated implementations that scale across many teams.
• Comfortable in 0→1 environments, able to navigate ambiguity and bring crisp product thinking to technical trade‑offs.

Benefits & Compensation

• Base pay range: $255,000 – $325,000 (offers equity).
• In addition to salary and equity, total compensation may include performance‑related bonuses for eligible employees.
• Medical, dental, and vision insurance with employer contributions to Health Savings Accounts.
• Pre‑tax accounts for Health FSA, Dependent Care FSA, and commuter expenses.
• 401(k) retirement plan with employer match.
• Paid parental leave (up to 24 weeks for birth parents and 20 weeks for non‑birthing parents), paid medical and caregiver leave, and paid time off (flexible PTO for exempt employees; up to 15 days annually for non‑exempt employees).
• 13+ paid company holidays and periodic company office closures, paid sick or safe time as required by law.
• Mental health and wellness support; employer‑paid basic life and disability coverage.
• Annual learning and development stipend; daily meals in offices and meal delivery credits as eligible.
• Relocation support for eligible employees.
