How would you explain the Forward Deployed Engineer role and its responsibilities alongside customer and product teams?

Example Answer

An FDE owns engineering work close to the customer: understand the workflow, turn it into a buildable scope, implement the integration or application, and verify that people can operate it. I'd expect to write code and make technical decisions, while staying close enough to users to notice when our design solves the wrong problem.

I'd work with customer engineers on data, access and deployment, and with operators on ordinary and exception cases. Recurring problems could become reusable code or a product proposal. The role may involve AI, but its value is a working customer solution. I'd clarify this employer's coding ownership, production support and handover responsibilities, alongside Product's roadmap and the customer's business authority.

Make it your own

Name the product and customer environment you understand. Ask the hiring team how much coding the role owns and where production support sits.

Why this works

The answer links discovery to implementation, verification and handover. The employer pages illustrate different engineering roles; they do not establish a universal FDE definition or interview format.

Interviewer follow-up

How would you tell whether an advertised FDE role is mostly presales?

I'd ask what engineers deliver after the customer signs, who commits code, and whether the team owns deployments or primarily hands specifications to someone else. I'd request an example project and ask how success was assessed. Demonstrations and technical discovery can be useful work, but I'd clarify their share of the role before treating it as hands-on production engineering.

Assessment criteria

These are practice criteria for this scenario, not an employer's scoring rubric.

• Strong: Connects discovery to code, deployed verification and handover; clarifies this employer's ownership boundaries.
• Adequate: Explains customer-facing engineering and asks about coding or support responsibility.
• Weak: Treats the title as proof of one universal job description.

A tempting weak answer

"I'd mainly demo the product and pass implementation to Engineering."

Why it fails: That may describe another function, but does not demonstrate the hands-on ownership this question asks about.
