Dalus (YC W25) is hiring a founding engineer for hardware system design software

Summary

Why Dalus Exists At Dalus, we're building AI-powered software to reimagine how complex hardware systems are designed — think rockets, satellites, EVs, aircraft, nuclear plants. Right now, companies building these systems are held back by legacy tools that were never built for today’s fast-paced engineering teams. We’re changing that. Our platform makes hardware development faster, safer, and more scalable, even with smaller teams. We believe that designing atoms should feel more like working with bits — and that the next industrial renaissance needs better software. More on our vision here About the Role We’re looking for Founding Engineer #1 — someone who wants to go deep, build fast, and shape the future of our product and team. You’ll be working across the entire stack (frontend, backend, AI, systems modeling) and helping us deliver real value to some of the most advanced hardware companies in the world. You’ll thrive in this role if you: Love wearing multiple hats and learning new things fast Have strong product intuition and care about UX Are excited to build the future of complex system design, not just work on it Don’t mind getting your hands dirty with hard problems (and hard schedules) Our Stack Frontend: Next.js, Typescript, React Backend: Node.js, Python (for simulation/AI), AWS AI: Different LLMs, Langfuse, agent tooling workflows Who We Are We started Dalus in 2024. Eliot was a test/systems engineer at Aerojet Rocketdyne (L3Harris), where he saw firsthand how siloed communication slowed down hardware teams. Sebastian previously founded a neurotech hardware startup and scaled a software company to exit. We just wrapped up YC W25, have revenue, and are working closely with aerospace, robotics, and defense customers What You’ll Do Own major product features from idea to production Work directly with customers to understand pain points Help shape the architecture and engineering culture Get hands-on with AI workflows, model interfaces, and simulations Scale...
