Tessl is the platform for building software factories.

AI coding agents can write code fast, but most teams end up with a pile of one-off automations, not a system they can trust or scale. Tessl gives your team a working software factory without the headache: it extracts automated workflows and agent improvements so you don't have to, built on best-in-class factory components so your time goes into automating your work, not building plumbing.

Your team builds it, one workflow at a time, catching insecure or low-quality skills before they ship, enforcing standards across every agent and repo, and turning one engineer's automation into a reusable asset for the whole org, without locking into a single vendor.

Tessl

Reimagining software development for the AI era, and shaping AI Native Software Development.

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.

About The Role

Events are one of the main ways Tessl builds real relationships with developers, customers, and partners. We're looking for a mid-level Events Marketing Specialist in New York to run our growing US events program on the ground: community meetups, developer chapters, conferences, partner and customer events, and larger Tessl-owned moments.

This is a hands-on execution role, with the opportunity to influence our events strategy as we grow our presence in the US. You'll take an agreed plan and make it real, and you'll be the person in the room making sure it runs. Most of the team sits outside the US, so you'll own your events with real autonomy, while sharing learnings and the impact of events on our growth goals with the wider team.

What You'll Do

Run US events end to end

Own operational delivery once strategy, objectives, and format are agreed: timelines, run-of-show, budgets, vendors, venues, catering, AV, signage, swag, and shippingBe the primary owner on the ground, and troubleshoot calmly when something breaks an hour before doors openMake Tessl events feel considered and consistent, not just staffed

Support the developer community program

Help chapter leaders across the US navigate venues, formats, logistics, swag, and promotionShow up for priority community events and represent Tessl in the roomBuild repeatable resources so local chapters get more self-sufficient over time

Coordinate conferences, partner and field events

Manage Tessl's presence at third-party conferences and developer events, and support commercial B2B activations with Sales and Partnerships: booths, sponsorships, side events, dinners, and co-hosted eventsKeep both sides clear on responsibilities and deadlines on co-hosted events, and support larger programs like US roadshows alongside senior team members

Help fill the room

Work with Marketing, Community, and Sales so every event has a promotion plan and the assets to back itFlag early when registrations track below target, and help identify the local communities and companies worth reaching (audience acquisition matters here, but this isn't primarily a demand generation role)

Keep everyone aligned

Maintain a single source of truth for each event so people know what's happening and what they ownSurface risks and blockers early with a proposed fix, and work smoothly across time zones with the UK-based Marketing and Community teams

What Good Looks Like

US events run smoothly without senior team members managing every operational detailPlans are current and trusted, and everyone knows what's expected of them and whenProblems surface early, with solutions rather than surprisesEvents feel polished and intentional on the groundOur community program expands, with regular, well-attended meetups in key US citiesChapter organisers feel well supported and grow more self-sufficient over timeEvents contribute measurable value to our growth goals, generating sales opportunities and growing our communityAwareness of Tessl and AI Native Dev grows among developers and technical leaders in the US

What We're Looking For

We're looking for a strong operator and doer. You don't need to bring a new events strategy; you need to be very good at turning plans into reality.

Must have:

A few years running events, field marketing, or community events, from planning through to live deliveryExcellent organisation and project management, with real attention to detail across several events at onceA proactive communicator who keeps people informed rather than waiting to be askedGood judgment and the confidence to make sensible calls independentlyExperience managing external vendors, venues, and event partnersHappy to get hands-on: as comfortable talking through a plan with a senior stakeholder as tracking down a missing shipment before doors openComfortable in a fast-moving company and working with a distributed international team

Nice to have:

Experience with developer, technology, or startup community eventsExperience supporting community chapters, ambassador programs, or meetup organisersBoth community-focused and commercial B2B/field event experienceFamiliarity with the New York technology and developer sceneSome experience promoting events through community channels, email, social, or local outreach

Location and Travel

This role is based in New York, with regular travel across the US. You'll be Tessl's primary events operator on the ground, so you should be happy to travel when your presence will make an event materially better. We don't expect you at every Tessl event. You'll also work with the global Marketing and Events team at larger moments and team gatherings.

Salary and Benefits

Salary: We offer a competitive salary based on experience and skills, benchmarked against industry standards.
