About this role

Developers in this position build advanced AI coding workflows, integrations, automations, and evaluation systems by writing code directly and often utilizing Codex within their own development process. Partnership with leading engineering organizations defines the core mission, focusing on taking ambitious ideas from workflow selection through prototyping, evaluation, production rollout, and scaled adoption.

OpenAI's Applied AI Engineering team helps organizations transform software development lifecycles by turning frontier AI capabilities into reliable production systems. Professionals who thrive here combine deep technical judgment, hands-on engineering, and customer leadership to guide technical decisions regarding model behavior, agentic workflows, and developer environments.

What you will do

  • Partner directly with engineering leaders and hands-on developers to design and deploy AI systems that transform software development.
  • Work hands-on in code to build prototypes, evaluation harnesses, reference implementations, integrations, and production accelerators.
  • Help customers progress from promising experiments to reliable production workflows and sustained developer adoption across organizations.
  • Design systematic approaches for evaluating AI coding systems using representative tasks, automated graders, and production signals.
  • Make sound technical decisions across models, agents, tools, reliability, observability, security, and operational readiness.
  • Gather high-fidelity insights from real-world deployments and translate them into clear product proposals and technical requirements.

What you need

  • Demonstrated track record of designing, building, and delivering software or AI systems in enterprise environments from prototype to production.
  • Substantial personal contributions in code, architecture, evaluation, debugging, integrations, or production engineering.
  • High proficiency in Python along with comfort working across modern software development environments.
  • Active use of AI coding tools with a strong perspective on improving developer productivity and software engineering workflows.
  • Ability to navigate enterprise production requirements including tooling integrations, reliability, security, privacy, performance, and cost.
  • Fluency in both English and German.

Nice to have

  • Experience with JavaScript, TypeScript, or another relevant language

Benefits

  • Relocation assistance to new employees
