Founding Sales Engineer

Clarasight•Lisbon, MA

55d

About The Position

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 transform prospects into believers not just buyers. 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.

Requirements

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 Haves

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