Software Engineer, API Multimodal

OpenAI is hiring a software engineer for its API Multimodal team to build and operate the developer-facing products and infrastructure behind its image, audio, and real-time APIs. The role involves designing low-latency streaming and model integration systems, partnering with research and safety teams, and shipping frontier multimodal capabilities to developers. This hands-on backend engineering role combines systems depth with product judgment.

• Design, build, and ship developer-facing APIs and backend services that serve frontier models.
• Architect low-latency streaming, request, session, and model integration systems that make complex multimodal interactions reliable and intuitive at scale.
• Work directly with Research to bring new model capabilities into production, shape the systems around them, and incorporate feedback from real-world developers and customers.
• Own the availability, latency, scalability, and cost efficiency of the services you build.
• Own projects from technical design and implementation through launch and ongoing iteration, while raising the team's engineering standards.

• 7+ years of professional experience, excluding internships, in backend, infrastructure, platform, or product engineering roles.
• A track record of designing, building, and operating production backend services, developer-facing APIs, or distributed systems.
