About the job
OpenAI is seeking a backend engineer to adapt its API platform for strategic cloud environments, starting with AWS. This role involves building backend services, APIs, SDK integrations, authentication flows, and cloud service infrastructure to enable developers to use OpenAI capabilities within their existing cloud environments. You will work across teams, sometimes embedded with partner product groups, to ship products quickly and across multiple platforms simultaneously. This is an excellent opportunity for engineers who have experience building developer tools, particularly AI-powered ones, can communicate effectively across technical disciplines, and can design architectures supporting diverse deployment models.
Responsibilities
- Build backend and infrastructure systems to extend OpenAI's API platform into cloud-native environments like AWS.
- Design and ship cloud-contained products enabling customers to use OpenAI capabilities while keeping workloads and data within cloud environments.
- Help establish cloud-hosted Codex experiences powered by the OpenAI Responses API.
- Develop infrastructure and runtime abstractions for a stateful, cloud-optimized agentic platform.
- Collaborate with external cloud partners and internal teams (Codex, Research, Safety Systems) to productionize emerging capabilities.
- Enhance the reliability, scalability, observability, and operational maturity of underpinning services.
- Contribute to shaping the technical direction of a new and growing team.
Requirements
- 7+ years of professional engineering experience in relevant roles at tech and product-driven companies.
- Proficiency in one or more backend languages (e.g., Python, Go, Rust, Typescript) and distributed systems concepts.
- Experience building developer tools, especially AI-powered tools.
- Excellent technical communication skills.
- Ability to shape architectures supporting different deployment models.
- Experience building cloud services is a strong plus.
- Experience turning ambiguous, fast-moving technical problems into pragmatic, durable systems.
- Experience with cloud infrastructure primitives and production service ownership.
- Experience collaborating cross-functionally with platform, research, safety, or external partner teams is a plus.
- Interest in AI infrastructure, agentic systems, and developer platforms.
- Interest in AI/ML (direct experience not required).
- Proven ability to thrive in fast-growing, product-driven companies by effectively navigating loosely defined tasks and managing competing priorities or deadlines.
