Why its hard to evaluate what makes a great Forward Deployed Engineer.

There’s a lot of craze over the Forward Deployed Engineer role in tech right now. A ton of interest, and in many places very little clarity or consistency around what the job actually entails.

Most job descriptions for FDE roles read like a generic senior SWE posting with "customer-facing" tacked on. But the engineers who actually thrive in the role have a pretty specific combination of traits that doesn't show up cleanly on a resume or in a standard technical interview.

From what I've observed, strong FDEs tend to share a few things:

They're comfortable with ambiguity. An FDE at a customer site might debug a data pipeline at 9am, write a quick internal tool by lunch, and explain architecture tradeoffs to a non-technical stakeholder by 3pm. A lot of breadth, and many different hats throughout the day.

They bias toward shipping over perfection. The feedback loop is fast and customer-driven. Engineers who need to "finish" something before showing it tend to struggle. This can be incredibly enjoyable but also quite daunting and naturally comes with a lot more “failure”.

They have strong written communication. A lot of FDE work happens asynchronously across customer orgs. The ability to write a clear technical summary that a VP can understand without losing the engineer reading it is underrated.

The frustrating thing is none of this shows up in a LeetCode score or even a typical system design interview.

I've been building a tool called Trait that tries to surface FDE signal differently — you upload a few simple documents and do a short voice conversation, and it gives you a confidence-weighted fit score. It's early, but I'd love feedback from people who've worked in or adjacent to FDE roles on whether the framing resonates.

Curious whether others have thoughts on what actually separates strong FDEs. I think it’s a role that is just beginning to truly take shape but will be wildly impactful for the next ten years.
