Member of Technical Staff (Platform Leaning)

Descripción del puesto

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 Join our engineering team to build real-time AI Native workflows, tooling, and interfaces that will reshape how developers create and maintain software. This is a product engineering role with a platform twist. Most of your time, you'll do what every Tessl engineer does: design, prototype and ship product features end to end, collaborating closely with product, design and the wider engineering team in a fast-paced, high-autonomy environment. What makes you different is that when the work goes below the application layer, you light up rather than back away: complex networking scenarios such as site-to-site VPN and private connectivity, multi-cloud and multi-region deployments, observability, and the machinery that makes Tessl straightforward to deploy, operate and support wherever it needs to run. We expect you to be relentlessly AI native about it: instead of triaging alerts at 2 am, you'll build or deploy the agent that does it. Instead of reacting to scaling bottlenecks, you'll create systems that spot them before they happen. Deep expertise is the foundation, because you can't automate what you don't know, but your ambition should be to make agents do the bulk of the operational work, with you supervising and steering. We're open on level for this role, from mid-level to senior: trajectory and appetite matter more to us than years. What success looks like: Within your first year, you're shipping product
