Module 1 · The FDE role and mindset · Chapter 1
What an FDE actually does
Three jobs share one title
An analysis of about 1,000 FDE job postings by Bloomberry found roughly 60% were builder roles (writing production code at the customer), about 30% were sales-engineer-plus roles, and about 10% built internal go-to-market tooling. Same title, very different days. This course targets the builder FDE, and shows you how to read a posting so you can tell which one you are applying for.
Where the time actually goes
Click through the roles. The bars are illustrative, not measured: they show where each role spends its attention, and why moving from SDE to FDE feels like a different job rather than a promotion.
The engagement lifecycle
Every FDE engagement moves through the same five stages. Step through it. Notice where the work changes character: a proof of concept is a magic trick, and production is plumbing.
- Sit with the customer. The stated ask ("AI for our supply chain") is rarely the real problem. You leave with a problem statement, a named champion and a measurable success criterion.
- Build the smallest thing that shows the idea working, fast. It runs on sample data and your laptop. Be careful: a good demo creates expectations you now have to meet.
- Real users and real, messy data. Permissions, edge cases and "this doesn't match our process" all appear here. Many projects stall at this stage when nobody owns the move to production.
- Monitoring, access control, security review, runbooks, on-call and a rollback plan. This is where an SDE's habits help the most, and where the customer-facing skills matter just as much.
- A working deployment earns the next team and the next use case. You reuse what you built instead of starting over.
- An FDE does not only deliver. Hacks that worked at one customer get turned into product features, so the next deployment is faster. That loop is what separates an FDE from a consultant.
The gap between a working demo and a system the customer trusts is where projects commonly stall. Demos run on clean sample data and skip access control, monitoring and ownership. Closing that gap is a large part of what customers pay an FDE for, and it is why this course spends whole chapters on the production side (Modules 5 and 6).
Try it: your first customer call
The VP just said "We need AI for our supply chain." Choose how you respond. There is no single right answer, but some choices build trust faster and others quietly set up a failure three months out.

Recap
- "FDE" covers three jobs. Read the posting; this course targets the builder FDE.
- The FDE owns the whole path from discovery to production, not only the build.
- The demo-to-production gap is where most of the value (and risk) lives.
- What you learn in the field flows back into the product. That loop defines the role.
