Forward Deployed Engineer (FDE)

TL;DR

An experienced software engineer who works directly within a client's context — as part of the team, not as an external advisor. Delivers code, not slides, and takes ownership of architecture decisions.

What is a Forward Deployed Engineer?

A Forward Deployed Engineer (FDE) is a senior-level software engineer embedded in a client’s team who builds concrete features to production and takes on strategic and architectural ownership. The term originated at Palantir and was adopted by OpenAI, Anthropic, Scale AI, and Lovable. Today it’s the standard model at AI-first companies in the US.

Unlike a traditional consultant, an FDE delivers code rather than recommendations. Unlike a regular freelancer, an FDE thinks alongside the team instead of just working through tickets.

Example Use Case

A B2B SaaS company wants to add an AI co-pilot to their product. The internal team has strong full-stack engineers, but no one has hands-on production RAG or agentic experience. Instead of waiting 9 months to hire a senior AI engineer or briefing an agency, they bring in an FDE for three months. He builds the feature to production, documents the architecture, trains the team — and steps back once it runs independently.

When This Is Relevant for You

I work exactly in this model — as a Forward Deployed Engineer for software companies, scaleups, and mid-market firms. More on the FDE service page.
