About The Position

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. We're looking for a Developer Advocate 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 builder. That means creating integrations, and tools that showcase what AI native development can really look like. You'll create compelling content, engage deeply with the community, and help developers understand what's possible when they build with Tessl.

Requirements

Already in the conversation: You're an active voice in the AI developer community, on social channels, where AI discussion is happening. You post, reply, spark discussions.
Active at events: You speak at meetups or conferences, engage in developer communities, and have a point of view worth hearing.
A builder's mindset: You get excited about making things. Whether that's a slick integration, a creative app, or an experiment that no one's tried yet, you'd rather ship something than just describe it.
Strong communicator: You can write clearly and engagingly about technical AI topics.
Development skills: You're comfortable enough with code to build and hack on things yourself. You don't need to be a full-time engineer, but you ship.

Nice To Haves

Experience with open-source communities and contributor ecosystems
Existing network in the AI developer tooling space
Comfort operating in a fast-moving, early-stage startup environment

Responsibilities

Build with Tessl: Go beyond writing about the product, build with it. Create apps, integrations, and creative projects using Tessl that inspire and enable the developer community to do the same.
Content Creation: Write articles, tutorials, and guides, and produce videos that give developers practical, actionable insights into AI native development with Tessl.
Community and Events: Be an active, visible presence in the AI developer community, speaking at events, participating in forums, engaging on social, and helping highlight what developers are building with Tessl.
Ecosystem Exploration: Constantly explore the AI developer tooling landscape, identifying integration opportunities and ways to connect Tessl with the broader ecosystem.
Show Up Where Developers Are: Run webinars, appear on podcasts, and make yourself at home in other people's communities. That means Discord servers, Slack groups, subreddits, newsletters, and anywhere else developers are gathering.
