Tessl

Field Engineer – Presales

Tessl

Field Engineer engaging customers and defining solutions for AI-native software development at Tessl. Collaborating with engineering teams and driving post-sale success.

Posted 6/30/2026full-timeNew York City • New York • 🇺🇸 United StatesMid-LevelSeniorWebsite

About the role

Key responsibilities & impact
  • Help build field engineering from the ground up — as one of the first field engineers at Tessl, you'll help define how we engage customers technically, shape the playbooks, and establish the systems and processes that scale with the team
  • Own the technical relationship in sales cycles — run demos, answer hard questions, and build trust with engineering audiences ranging from individual developers to CTOs
  • Understand customers' environments — their agent tooling, developer workflows, CI/CD pipelines — and design solutions that map to how their teams actually work
  • Guide onboarding and adoption — work with customers post-sale to ensure they're getting real value from the platform, not just licenses
  • Code alongside the product team — contribute to product development, build integrations, and prototype solutions that inform the roadmap based on what you see in the field
  • Build AI-first GTM tooling — design and ship internal tools that make our go-to-market motion smarter: automated demos, AI-assisted onboarding, technical qualification tooling, and more
  • Surface product insights — act as the voice of the field back to engineering and product; the patterns you see across customers are signal we need

Requirements

What you’ll need
  • A builder first — you write code, not just read it; you're comfortable shipping integrations, tooling, and prototypes as part of the job, not as a side activity
  • Deep sales cycle fluency — you've operated in enterprise technical sales, understand the full arc from qualification to close, and know how to navigate multiple stakeholders, technical evaluations, and POCs without losing momentum
  • Full customer lifecycle ownership — you're as comfortable driving post-sale success as you are closing pre-sale; you care about customers getting real outcomes, not just signing contracts
  • Fluency in the AI tooling ecosystem — you know how tools like Claude Code, Cursor, Copilot, and Gemini work and how engineering teams are adopting them day-to-day
  • Comfort with ambiguity — field engineering at Tessl doesn't have a defined playbook yet; you'll write it, and you're energised by that rather than unsettled
  • Clear technical communicator — you can make complex ideas legible to both skeptical engineers and less-technical stakeholders
  • Collaborative by default — you work fluidly across sales, product, and engineering, and you treat what you learn in the field as shared intelligence
  • 5+ years of experience in a field engineering, solutions engineering, or technical pre-sales role

Benefits

Comp & perks
  • Health insurance which extends to partners and dependents
  • Pension
  • Regular socials such as team lunches, drinks and more
