Tessl is a fast-growing Series A startup based in London, founded by Guy Podjarny. We’ve raised over $100M from world-class investors including Index Ventures, Accel, GV, and Boldstart, and in 2025 we were ranked #2 in Sifted EU’s B2B SaaS Rising 100 and #20 in Sifted's AI 100. At Tessl, we are building the context layer for AI coding agents, and a platform for AI-native software development. As an early member of the team, you’ll help shape how we build, scale and support a company operating at the edge of AI and software development. OVERVIEW OF ROLE We're looking for a Field Engineer who lives and breathes the AI space. Someone already deep in the AI developer ecosystem, building with it, talking about it, and pushing what's possible with it every day. In this role, you'll be a power user of our product and a trusted technical partner to our customers. That means running deeply tailored demos, designing solutions that map to how engineering teams actually work, and helping developers and platform teams understand what AI-native software development can really look like. You'll engage deeply with the community, and bridge the field back to our product and engineering teams. WHAT YOU'LL DO - 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 in
