Overview
We are looking for engineers who combine technical depth with real‑world impact and who are keen to grow into broader architectural and leadership responsibilities. OpenAI is central to our work, but we also value curiosity and awareness of the wider LLM ecosystem to help make thoughtful, well‑rounded technical decisions.
Responsibilities
- Design and build AI applications using OpenAI and related technologies.
- Develop production-ready systems across APIs, backend services, and user-facing applications.
- Deliver GenAI solutions including RAG pipelines, tool use, and evaluation frameworks.
- Contribute across the full solution lifecycle: design, build, testing, deployment, and iteration.
- Support development of agentic systems (multi‑agent workflows, orchestration, human-in-the-loop).
- Optimize performance, cost, and maintainability in cloud environments (AWS/Azure).
- Work closely with clients to shape practical, business‑aligned solutions.
- Communicate technical decisions clearly to technical and non‑technical stakeholders.
Candidate Qualifications
- Strong hands‑on software engineering experience, particularly with Python and backend/API development.
- Proven experience building production-ready systems and practical delivery of LLM / GenAI applications (e.g., RAG, tool use, structured outputs, evaluation).
- Ability to work across the full delivery lifecycle.
- Cloud experience in AWS or Azure.
- Strong engineering practices (testing, CI/CD, version control, secure development).
- Comfortable in client‑facing environments, translating business needs into solutions.
- Experience with OpenAI or similar LLM platforms and exposure to agentic architectures (multi‑agent systems, orchestration, HITL workflows).
- Experience with vector databases and familiarity with PyTorch or TensorFlow.
- 0–1 product development experience.
