Description

You are the technical voice in every deal that matters at Fifth Dimension. As a Founding Technical Pre-Sales Engineer, you will own the technical side of winning enterprise deals across the US. You will report directly to the CPO and be the first dedicated pre-sales hire.

Your day-to-day responsibilities will include:

  • Building the pre-sales playbook, demo environments, battle cards, and competitive positioning from humble beginnings
  • Partnering with AEs to prioritize pipeline, coach on technical positioning, and ensure every high-value conversation has technical depth
  • Bridging won deals to the implementation team with clean handoffs and scoped requirements
  • Carrying the voice of prospect technical requirements into Product and Engineering, shaping the roadmap with deal intelligence
  • Uniting long-term product vision from the founders with daily deal implementation and sales
  • Traveling 25 to 30% to prospect and client sites across the US
