Full-stack Engineer Job at OpenAI (San Francisco)

Job Description

As a Full-Stack Engineer, you will design and build end-to-end web systems that serve both customers and internal teams. You’ll own the design and implementation of full-stack solutions—from early prototypes to production-ready systems—making thoughtful trade-offs around usability, security, and long-term maintainability. We’re looking for pragmatic builders with strong product instincts who move fast without compromising quality or security. You’ll work closely with designers, engineers, and cross-functional partners to identify pain points, prototype solutions, and take them from zero-to-one into reliable systems.

Design, build, and maintain web applications for external customers
design, build, and maintain internal tools used across hardware, research, design, operations, and software teams
rapidly prototype and iterate on new tools in close collaboration with stakeholders
architect and deliver full-stack solutions with a strong emphasis on usability and security
evaluate third-party and open-source solutions and make sound build vs. buy decisions
establish best practices for internal tooling, including code quality, reliability, and security

Requirements

7+ years of professional software engineering experience, with a focus on full-stack web development
proficient in rapidly building user-facing products and internal applications
experience working from zero-to-one on early-stage products and iterating quickly based on feedback
strong understanding of security principles and best practices for protecting sensitive data
familiar with a broad range of modern front-end and back-end frameworks and tools

Nice to have

experience building internal tools for multidisciplinary teams (hardware, research, operations)
track record of effectively selecting and integrating third-party or open-source solutions
strong design instincts and experience collaborating closely with designers
familiar with infrastructure and deployment for internal systems (e.g., containerization, CI/CD)
