How to hire a forward deployed engineer

Most hiring starts with a job description. Start one step earlier: write down what has to be true in three months that is not true today. “Our reconciliation runs in production and finance trusts it.” “The AI assistant answers from our own documents, and support uses it.” One or two sentences, in the language of the business.

That sentence does two jobs. It tells you whether you need a forward deployed engineer at all — if the outcome is “ship the next twenty tickets”, you need capacity, not ownership. And it becomes the brief you give whoever you bring in, which is exactly how a forward deployed engineer expects to be briefed.

Many teams do both: an engineer from a firm to own the urgent problem now, and a hire to own the system afterwards, with a handover built into the plan from the start.

A strong forward deployed engineer is a senior generalist whose best qualities rarely show up on a CV:

• —Ownership — they talk about systems they took to production and kept running, not features they worked on.
• —Integration instinct — they have made unfamiliar systems talk to each other, and can tell you where it nearly went wrong.
• —Clear writing — decisions, trade-offs and handovers written so that someone who was not in the room can act on them.
• —Composure with people — they can say “not like that” to a customer or a senior stakeholder, early and kindly.
• —Fluency with modern tooling, including AI coding and evaluation tools, used with judgement rather than faith.

Classic coding interviews test the wrong thing. The job is not solving a puzzle alone in forty minutes; it is understanding a messy problem with the people who have it. Interview for that:

• —Walk them through your real problem, with its real constraints, and let them ask the questions. The questions they ask tell you more than any answer.
• —Ask for a short written plan afterwards: what they would do in week one, what they would need, what worries them. You are testing the writing as much as the plan.
• —Ask about a system they owned end to end — what it was, what broke, what they would do differently. Listen for specifics and for “I” where it was theirs.
• —Include someone non-technical in one conversation. A forward deployed engineer spends real time with users and stakeholders.
• —If you can, run a short paid trial on a real piece of the work. It is the most honest interview there is.

• —Every past project was a team effort they cannot describe their own part in.
• —They ask for a detailed specification before they will say anything useful.
• —They have never been on call for anything they built.
• —They agree with everything — including the parts of your plan that are wrong.
• —For a firm: they cannot tell you who the engineer will be, or the engineer changes after the sale.

Forward deployed engineers are only as fast as their access. Most of the first week is lost when access arrives piecemeal. Have these ready on day one:

• —Repository access, and the ability to open and merge pull requests through your normal review.
• —Cloud and infrastructure access at the level the work needs, on credentials you can revoke.
• —The issue tracker, the team chat, and invitations to the stand-ups that matter.
• —Access to the data the problem lives in — or a clear, fast route to it.
• —One named person on your side who can make decisions and answer “why is it like this?”

Ask for something small in production by the end of the first week. It proves the path from laptop to live works, and everything after it gets faster. That is how every Azenvoc engagement starts.
