## Description

About Tessl AI is transforming how software is built, and at Tessl, we're building the infrastructure for what comes next. We're developing a platform that enables engineering teams to build and run AI-powered software factories, where coding agents take on real development work, from picking up engineering tickets to implementing changes and creating pull requests. By combining structured context, reusable agent skills, automated workflows and evaluations, we're making AI-powered development more reliable, repeatable and scalable, while keeping humans in control. We're tackling some of the biggest challenges in autonomous software development, from code quality and security to helping organisations confidently adopt AI agents at scale. Founded by Guy Podjarny, previously founder of Snyk, Tessl is a fast-growing Series A startup backed by over $100 million in funding from investors including Index Ventures, Accel, GV and Boldstart. Joining Tessl means helping define an entirely new category of technology, solving ambitious technical challenges and shaping the future of software development. OVERVIEW OF THE 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 features end to end like any Tessl engineer. When infrastructure work arises, from deployment architecture to networking to observability, you're the one who takes it on and lands it well, with support where you need it. Our deployment and operational practices are stronger because of you, agentic tooling handles a growing share of the toil, and the infrastructure work you touch is compliant by default, keeping our ISO 27001 and SOC 2 journey unblocked. WHAT YOU'LL DO No two days will be the same at Tessl! You'll have a high level of autonomy and be empowered to make decisions based on what you believe will help you deliver the most success. Here's an insight into just a few of the things you would be doing: Product engineering (most of your time) Design and implement new functionality end to end, from initial design and prototypes to fully scoped production implementations, reviewed with the product team Rapidly prototype new capabilities to prove or disprove an idea, then develop a plan for a scalable implementation Pair with designers and other engineers to make the experience intuitive and slick, and integrate third-party services so we can focus our cycles on Tessl's core capabilities Gather requirements from customers and stakeholders, turn ambiguity into agreed plans, and deliver them Platform & infrastructure Lean into infrastructure work as it arises: our AWS estate (EKS/Kubernetes), infrastructure-as-code,
