Impact You'll MakeFlightline started as an AI-native start-up built to rethink how consulting work gets done: how research is gathered, how analysis comes together, and how insight reaches the people making decisions.In October 2026, Stout, a global advisory firm with more than 30 years of experience and 1,000+ professionals, acquired Flightline to put itself at the forefront of how AI is changing knowledge work. Flightline teamed up with the firm's strategy consulting practice, Stout Strategy. For 20+ years, Stout Strategy has advised private equity firms and global Fortune 1000 corporates on investment diligence and growth strategy, with over 500 PE processes and more than 1,000 corporate growth strategy assessments behind it.The combination is rare: technology built the way a start-up builds it, with deep domain expertise in-house to define what great work looks like. That's how we intend to be the fastest to market, with the highest-quality work.As a Senior Full-Stack Engineer in our Applied Innovation Group, you get the best of both worlds: working at the frontier of AI and knowledge work, inside a firm with the clients, expertise and scale to make it succeed. Teams across the firm are adopting Flightline quickly, and we're growing our small team to keep pace. You would join as the third engineer, in a team where everyone covers a lot of ground. You will work closely with the Managing Director, Applied Innovation, who leads the group, and collaborate day to day with the other engineers and our UI/UX and product colleagues, while owning meaningful elements of the platform. * Work on a real product that consultants use on live client work, across the whole stack, and see the effect of what you ship quickly. * Own real areas of the platform and grow with them as more teams across the firm adopt it. * Learn quickly: new domains, new parts of the system and new AI tooling, alongside a small team that will help you get up to speed. * Turn expert judgment into engineering: the evals, tests and checks that make AI-generated work trustworthy. What You'll Do * Ship features from refined requirements to production across the frontend and the backend. * Take ownership of areas of the platform, such as a data pipeline, a service or a part of the UI. * Work on the LLM-backed core of the product, including extraction, retrieval, chat and content generation, and help measure and improve output quality. * Use AI coding agents as a core part of the development workflow: break work into well-specified tasks, review agent output closely, and take over when writing the code by hand is faster or safer. * Build the tests, evals and checks that make AI-assisted changes quick to verify and safe to ship. * Pick up whatever the team needs next, whether that is a bug in unfamiliar code, a new integration or a quick tool for consultants, and learn what you need to do it well. * Partner with consultants, product and design to sharpen requirements early. What You'll Bring * Five or more years of professional software engineering across the full stack: user interfaces, server-side logic, APIs, data stores and background processing, including running what you build in production. We care more about what you've shipped and run than about the number of years. * Experience in the languages and frameworks you know best. We use React, TypeScript and Python today, but we don't require any of them. What matters is that you can pick up a new stack quickly, as
