Full-stack quantum computing: From quantum hardware to software layers and beyond, we build across the full-stack. High-performance playground: We aim high, and we know sustainable performance only works when life outside work does too—hybrid setups, flexible hours. Never the smartest: Expect to learn constantly. You won't always be the smartest person in the room, and that's the point. Approachable leadership: Flat hierarchy, direct access. Feel free to approach any leaders. They're friendlier than they look! The sweet spot: Big enough to matter. Small enough to move fast. Growing between a startup and a corporation. We’re in the phase where top performers get noticed. Bigger than IQM: Our people build know-how for the entire quantum ecosystem. We publish papers, run hackathons, and help shape a market that's still being defined. The future of computing won’t build itself. You might be one of the few who do. Meet our people and learn more about IQM on our stories page. Explore our scientific publications.
