OpenAI's Applied Foundations team, part of its Applications Engineering organization, is hiring backend engineers to build the platform layers behind ChatGPT and Codex. The work covers scalable backend services and APIs, identity and access, safety, payments and commerce, plus storage, retrieval and compute. The posting asks for strong experience with distributed systems, APIs, production services and data pipelines, in Go, Python, Rust or C++. The role sits on shared product foundations rather than model research, and includes designing defenses against adversarial attacks without hurting user experience.
