What the role involves¶
FDE means Forward Deployed Engineer; “Forward Deployed AI Engineer” makes the AI specialism explicit. The central responsibility is getting a useful system working in a customer's environment. OpenAI's Seattle posting spans discovery, implementation and production rollout, with adoption and workflow impact as outcomes. Anthropic's Munich posting combines embedded customer work, production applications, reusable deployment patterns and feedback to product teams. Together they support a delivery role with substantial engineering and customer contact.

Expected evidence therefore spans both code and decisions: a scoped workflow, integrated application, evaluation results, rollout plan and a supportable handoff. The postings require production engineering, communication under ambiguity and understanding of customer systems. Anthropic also names agent development and evaluation frameworks. Travel, languages, seniority and account responsibilities depend on the particular posting; a requirement in one location is not a universal FDE qualification.

For preparation, distinguish four boundaries. A solutions architect may concentrate on design and technical adoption; an FDE remit should be checked for implementation ownership. Presales may centre on winning an evaluation; deployment work continues into operational use. A product engineer usually improves a shared product; an FDE also handles a customer's local integration constraints. A consultant can do overlapping work: the title alone says little about who maintains the result or turns it into reusable product capability. These are comparison questions, not rigid employer-wide definitions.

Preparation¶
Preparation route: take the engineering learning path, deepen customer scenarios, and practise enterprise access design, safe ERP writes and release gates. Add a short discovery conversation: identify the user, current workaround, permitted data, useful outcome and owner after launch.
Practice deliverable: build a small fictional service workflow with one external integration stub. Demonstrate a denied permission, a timeout after a possible write, and a quality regression. Explain the acceptance evidence and handoff. A polished demo without those checks is incomplete preparation. For a target vacancy, clarify who owns implementation, production support, commercial decisions and travel before choosing your strongest real examples.
