Forward deployed engineer is one title for three different jobs

An analysis of 1,000 job postings with the title found three jobs under one name. 60% write production code inside a customer's systems, 30% are sales engineers with a new label, 10% build internal tools. Before hiring, the question is which job you need.

Scaling AI past the first team: organizations with 15 to 99 engineers merge nearly twice as much per engineer

DX's quarterly report across more than 500 engineering organizations. Small organizations merge 2.2 pull requests per engineer per week against 1.2 at organizations of 750 or more, and while throughput rose 37% in four quarters, developer experience and change confidence fell.

AI coding assistants are in almost every engineering team, and write about 27% of the code that ships

Developers at more than 500 organizations report each quarter what share of their merged code an AI wrote. The average is 27.4%, and 30.8% among daily users. Adoption says who has a license; the merged share says who changed how they work.

AI in engineering teams, the people on call see the cost and the enthusiasts see the wins

Charity Majors, cofounder of Honeycomb, on why every engineering team has two camps about AI, why both are right, and why the line between them follows the on call rotation. What closed the gap in one client team was one page of shared numbers.

Keeping AI coding agents in line, written rules that tighten rather than sandboxes

One engineer ran 50 to 60 AI coding agents on a single codebase and ended up with 450 written rules, over 100 of them fences. A fence is any mechanism that turns an agent away when it is not supposed to be there. Rules tighten each time they are broken again, until a program enforces them.

Why a controlled study of AI productivity had to change its design

METR's February 2026 update lists four reasons its AI productivity experiment stopped working. Each one is what changes inside a team once agent adoption is real.

The forward deployed engineer role is posted ten times more, and few engineers want it

Job postings for the forward deployed engineer role grew more than tenfold in a year and about one in ten engineers wants the job. The title is not the hard part; the test is.
