Forward Deployed AI Engineer (f/m/x)

You sit with the business, not behind it. As a Forward Deployed AI Engineer, you’ll work side by side with our clients’ teams, find the problems worth solving, and ship AI products that solve them in weeks, not quarters. Part of the job is telling clients honestly what makes sense and what doesn’t, and explaining why. You own the whole path: from the first conversation with a business owner, through scoping, estimating, and budgeting the work, to a working prototype and a product in real use. Can’t remember how to derive the backpropagation formula? Last saw a partial derivative in your second year at university? Don’t worry, nobody here will ask you to prove your loss function is differentiable. In this role, success means business impact. You’ll use foundation models, APIs, and modern AI frameworks to build products that solve real problems. You’ll prototype quickly, put things in front of users early, and use what you learn to decide what to build next. The AI landscape changes every few months, so you’ll need to pick up new tools and approaches as fast as they appear and judge which ones matter. You’ll have a lot of autonomy and real influence. We’re looking for someone who spots opportunities, proposes solutions, and drives them forward without waiting to be told what to do. You’ll also help shape the strategy and growth of our AI business unit, so what you learn on projects will directly influence where we go next.
