Software Engineer, Codex Cyber

Details

Codex is OpenAI's software engineering agent. Codex Security extends that work into helping organizations find, validate, prioritize, and fix vulnerabilities in the software they build and depend on.

The Codex Cyber team is building product and platform foundations for AI-native application security, including Codex Security product experiences, cloud-based security analysis, platform controls across Codex, customer deployment and support tooling, and infrastructure that helps security researchers and cyber models improve over time.

This role is for a strong full-stack or product-minded software engineer who can own ambiguous product and platform problems end to end. Security experience is helpful, and security curiosity is important, but the role is focused on building software across user-facing product surfaces, developer workflows, backend services, security analysis pipelines, cloud infrastructure, and internal tooling.

Responsibilities

• Build end-to-end product features for Codex Security, including developer-facing interfaces, APIs, backend services, and workflow tooling.
• Own ambiguous 0-to-1 projects across product pods, platform security controls, customer deployment workflows, and cyber model infrastructure.
• Translate security research and model capabilities into intuitive workflows that help teams find, validate, prioritize, and remediate vulnerabilities with high signal.
• Design scalable and observable systems for long-running analyses across large codebases and enterprise environments.
• Partner with product, security research, infrastructure, and customer-facing teams to iterate quickly based on real-world feedback.
• Help shape the technical direction and architecture of Codex Cyber as the team and product surface area grow.

Requirements

• Excellent software engineering skills and strong fundamentals, with enough range to work across product, backend, infrastructure, and developer tooling.
• Experience building high-quality product and platform experiences across the full stack.
• Ability to own features from concept through production in a fast-moving environment.
• Experience with developer tools, workflow-heavy platforms, security products, internal infrastructure, or product features for technical users.
• Strong product instincts and the ability to make complex technical systems understandable and useful.
• Comfort with ambiguous 0-to-1 work and turning messy requirements into clear, scalable systems.
• Excitement about security and AI.
• Direct experience in product security, application security, vulnerability research, defensive security, identity, SSO, or secure developer workflows is a plus, but not required.

Goals And Impact

• Build AI-native security products that help users find and fix important vulnerabilities in real software systems before attackers do.
• Increase the usefulness and trustworthiness of Codex Security by turning research insights into dependable workflows, product surfaces, platform controls, and remediation tooling.
• Help define a new category of security tooling where models reason over real code, validate exploitability, and propose fixes directly in developer workflows.

Key Technical Challenges

• Combining model outputs, security analysis, and user workflows into one cohesive product experience.
• Designing high-confidence validation and remediation flows that distinguish real issues from noisy or speculative findings.
• Scaling product and platform infrastructure for large repositories, complex enterprise environments, and long-running analyses.
• Creating developer-friendly interfaces and APIs that make advanced security capabilities understandable and actionable.
• Building platform controls and internal systems that enable rapid development while meeting OpenAI's standards for safety, security, and reliability.

Benefits

• Base salary of $230,000–$325,000, plus equity.
• Medical, dental, and vision insurance, with employer contributions to Health Savings Accounts.
• Pre-tax accounts for health, dependent care, and commuter expenses.
• 401(k) retirement plan with employer match.
• Paid parental, medical, and caregiver leave.
• Paid time off, paid company holidays, office closures, and paid sick or safe time as required by applicable law.
• Mental health and wellness support.
• Employer-paid basic life and disability coverage.
• Annual learning and development stipend.
• Daily meals in offices and eligible meal delivery credits.
• Relocation support for eligible employees.
