Tessl is a fast-growing Series A startup based in London, founded by Guy Podjarny, who previously founded Snyk. We’ve raised more than $100 million from world-class investors, including Index Ventures, Accel, GV and Boldstart. In 2025, Tessl ranked #2 in Sifted’s B2B SaaS Rising 100 and #20 in its AI 100. We’re 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 and scale a company operating at the forefront of AI and software development.
Overview of Role
We're looking for a Developer Advocate to be Tessl's voice in the AI developer community — based in our London office and out in the world where developers actually are. Someone who lives and breathes agentic coding, builds real things with Tessl, and helps other developers do the same. This is a hands-on, high-visibility role. You'll build with the product, create content people genuinely use, speak at events, and be a familiar face across the communities where AI development is being figured out in real time. You'd rather ship a slick integration or a creative app than just write about one.
A big part of this role is education. Alongside the community work, you'll help build and grow Tessl Academy — our home for learning AI native development. You'll turn what you know into structured, hands-on learning that scales beyond any single talk or tutorial, and takes developers from curious to genuinely capable with Tessl.
Key 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.
- Teach through Tessl Academy: Design and deliver structured learning, including courses, hands-on labs, guided projects, and certification paths, through Tessl Academy that take developers from their first agentic build to real fluency. Own the curriculum, keep it current as the product evolves, and pay attention to what actually helps people learn, not just what looks good on a syllabus.
- 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.
What You'll Need
- 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.
- A teacher's instinct: You can break a complex AI topic into clear, progressive steps that meet developers where they are, and you enjoy the craft of helping someone go from lost to confident.
- 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 Have
- Experience building developer education, including courses, curriculum, academies, bootcamps, or technical training.
- Experience with open-source communities and contributor ecosystems.
We care deeply about the warm, inclusive environment we’re building at Tessl and we value diversity – we welcome applications from those typically underrepresented in tech. If you like the sound of this role but are not totally sure whether you’re the right person, do apply anyway!

How to prepare for a job interview at Tessl
✨Brush Up on Your Coding Skills
For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.
✨Know Your Tools and Frameworks
Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If Tessl uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.
✨Showcase Your Projects
Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.
✨Prepare for Behavioural Questions
While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
