Are you a Staff Fullstack Engineer who loves solving complex problems end‑to‑end and shaping systems that actually matter? At HERO, your work won't just power another app — it will become the digital backbone of Europe's trade and field‑service industry. Thousands of craftspeople rely on our cloud platform every day to run their entire business: from first quote to finished job, from the office to the job site.

We build software for people who wear boots, not suits — and we take that seriously. Our goal is to remove chaos, paperwork, and admin overload so trades businesses can work smarter, faster, and more sustainably. AI is becoming a core part of that mission: we're turning complex workflows into intuitive, assisted experiences that genuinely improve life for the people doing the real work.

As a Staff Fullstack Engineer at HERO, you'll be the technical force multiplier in a cross‑functional product squad. You'll collaborate closely with Product, Design, and fellow engineers from the very first discovery conversations through to rollout — shaping architecture, guiding systems decisions, and ensuring the things we ship are robust, observable, and built to last.

If you're looking for a role where you influence product strategy, elevate engineering culture, and build software used by thousands of craftspeople every single day — Welcome to HERO.
