About the role
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.
About the Role
We’re hiring a Product Marketer to define how Tessl shows up to the world.
You’ll sit at the intersection of product, growth, and sales - owning our positioning, messaging, launches, and enablement. You’ll help translate a deeply technical product into clear, compelling narratives that resonate with developers, engineering leaders, and forward-thinking teams.
This is an individual contributor role for someone who thrives in ambiguity, loves shaping category narratives, and wants to define how an AI-native product is understood in the market.
What You’ll Do
Positioning & Messaging
Own Tessl’s core messaging framework and value propositions
Refine and evolve our category narrative as the product and market mature
Develop audience-specific messaging for developers, tech leads, and enterprise buyers
Product Launches
Support go-to-market for new features and major releases
Partner closely with Product and Engineering to shape launch stories early
Create launch briefs, assets, and internal alignment materials
Content & Enablement
Develop high-impact product marketing content (website copy, one-pagers, case studies, blog posts)
Equip sales with compelling decks, objection-handling, and competitive insights
Support community and thought leadership initiatives
Market Intelligence
Conduct competitive research and positioning analysis
Gather insights from users, prospects, and the developer ecosystem
Feed structured insights back into product strategy
What We’re Looking For
Must have:
4–8+ years in product marketing (ideally in B2B SaaS or developer tools)
Experience owning messaging and content development end-to-end
Strong technical fluency — comfortable working with engineers and technical buyers
Exceptional writing skills with the ability to simplify complex concepts
Proven ability to operate autonomously in a fast-moving startup environment
Nice to have:
Experience marketing AI/ML or developer infrastructure products
Exposure to PLG and sales-assisted motions
Experience helping define a new category
Salary and benefits
Office: Our brand new 10,000 sq. ft office is in the AI hub of Kings Cross, London. We have generous catering and have regular social events such as team lunches, drinks and more. We require all staff to be in our London HQ at least 3 days a week on our anchor days of Monday, Tuesday and Thursday.
Salary: We offer a competitive salary based on experience and skills, benchmarked against industry standards.
Benefits: 25 days holiday, health insurance, including dental and vision, which extends to partners and dependents, as well as a company-matched pension. We also provide a commuting stipend for those who live outside London, and a cycle to work scheme.

Final conversation with leadership
We encourage you to apply even if you don’t meet every requirement. We care about talent, trajectory, and mindset, not just checkboxes.
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!
