Sales Engineer (Pre-sales Engineer)
Technical expertise in service of closing: advanced demos, POCs and architecture answers that win complex deals.
Why this hire matters.
On complex technical sales, the sales engineer is often the real reason a deal is won or lost: they convince the prospect's technical team — the one holding a silent veto over the decision. Their presence changes the cycle's economics: higher close rates on deals they join, scoped POCs that conclude instead of dragging on, architecture objections handled before they become blockers. Without one, your AEs improvise technically (and lose credibility) or drain your product engineers. The usual ratio is one SE for 2-4 AEs on mid-market/enterprise segments. In interviews, test both registers under real conditions: an improvised demo on a prospect case, and handling an aggressive technical objection.

Hiring this profile.
Typical background
An engineer who moved client-side, or a technical consultant. The tech + commercial dual skill is rare — that's what prices the profile.
When to hire
As soon as close rates drop in technical evaluation or POCs drain your product developers — moving upmarket to mid-market/enterprise, Series A/B.
Career path
Senior SE → Lead/Director Presales → VP Solutions, or a move to product/field CTO.
