Product Engineer (AI-Native Builder)

MiddleOn-site (Budapest)€60,000 – €80,000 / yr
Job Description

Traditional engineering roles hand you a task and ask you to implement it. This one hands you a problem and a fleet of AI agents and asks you to ship the solution. 

The Product Engineer / Builder is a Staff/Principal level individual contributor role, for someone who takes a defined problem and owns the solution end to end. You understand the customer and the problem, then design, build, and ship working software, using AI agents as your primary means of turning direction into product. You combine deep engineering craft with genuine product instinct, and act as a force multiplier rather than a single pair of hands.  

How You’ll Work 

Given a problem to solve, you shape the approach and use AI to bring it to life by directing several AI agents in parallel and rigorously reviewing what they produce. An idea sketched in the morning can be a functional prototype by lunch and a working product by the end of the week. You think like a product manager, care like a designer, and build like an engineer. 

This is not a role for someone who waits to be told exactly what to type. 

You bring taste and judgment to every decision. It’s your responsibility to know what to build, what not to build, and to prove — through evals, testing, and review — that AI-generated work is reliable enough to ship. You measure success in customer and business outcomes, not tasks completed. 

Build on What Works, Invent Where It Counts 

Build rapidly by composing solutions from the best available tools, whether internal or external, and apply your own innovation where it matters most. That means drawing on proven platforms, components, services, and models instead of building everything from scratch, then adding original thinking where there are gaps to close, experiences to elevate, or clear opportunities to differentiate. You know when to leverage what already works, when to extend it, and when to reinvent a piece entirely — always with the goal of creating meaningful product advantage, not just more code.
