About the Role

Clarasight is hiring our first Sales Engineer to help us win the deals that will define the company and category for years to come.

Your primary responsibility is to help us win complex enterprise deals. You will own the technical side of our most important opportunities, turning ambiguous customer problems into clear, compelling solutions that lead to closing deals.

At the same time, you’ll define how we do this at scale: how we run demos, how we prove value, and how customer needs shape the product. If you’ve ever wanted to be the person who writes the playbook instead of inheriting it, and sees the direct impact on revenue and product, this is that role.

What You’ll Do

  1. Win enterprise deals (increase win rates and shorten sales cycles)

    1. Partner with Sales to lead technical discovery, solution design, demo and technical deal strategy

    2. Deliver high-impact demos and proof of concepts that clearly show business value

    3. Act as the technical voice in complex, multi-stakeholder sales cycles

  2. Build how we win

    1. Define and refine our demo, proof-of-value, and technical validation approach

    2. Create repeatable assets and workflows that improve win rates without slowing us down

    3. Establish the foundation of a scalable presales function

  3. Design real solutions

    1. Translate customer needs into data models, integrations, and workflows

    2. Prototype lightweight solutions (scripts, integrations, AI workflows) where needed

    3. Ensure what we sell is grounded in what we can deliver

  4. Shape product and GTM

    1. Bring structured, high-signal feedback from deals into Product and Engineering

    2. Identify patterns across customers that should be productized

    3. Help refine how we position and package the product across use cases

What success looks like in 6–12 months

  • You’ve played a key role in closing our most important enterprise deals

  • We have a clear, repeatable demo and proof motion that consistently wins

  • Customer requirements are clearly shaping product direction

  • You are the go-to technical partner for high-stakes opportunities

Who You Are

  • You’ve been the technical lead on complex enterprise deals (Solutions Engineer, Sales Engineer, or similar) and know what it takes to get them over the line

  • You’re comfortable owning outcomes, taking responsibility for whether deals move forward, not just your part in the process

  • You can run discovery, design solutions, and deliver demos that directly influence buying decisions

  • You’re hands-on: comfortable writing code (Python, JavaScript, or similar) to prototype integrations, manipulate data, or validate workflows

  • You operate well in ambiguity and can move quickly with imperfect information

  • You think in systems - you don’t just solve one deal, you build ways to solve many

  • You communicate clearly and confidently with both technical teams and senior business stakeholders

  • Nice to have: You have knowledge of the tech ecosystem we typically encounter (e.g. TMC, OBT, Expense, Card)
