Braid Technologies

We’re building a next-generation platform for advanced engineering design automation – a system that goes from high-level problem descriptions to optimized, manufacturing-ready geometry. Think: compilers for physics problems, not just code. We’re looking for senior systems engineers with strong computer science foundations to help us build our core stack – from DSL compilers to high-performance geometry kernels. You’ll join a tight-knit, deeply technical team with backgrounds in C++, Rust, compilers, optimization, physics and mathematics. What you'll work on: - A custom compiler stack for our engineering DSL - High-performance geometric algorithms (meshing, optimization, constraints) - Systems-level architecture and backend infrastructure - Collaborative work with researchers, designers, and domain experts. You might be a fit if you: - Have strong CS fundamentals and systems programming experience - Know your way around C++, Rust, Python of functional languages - Enjoy writing performant, well-architected code for real-world math problems - Are excited by geometry, compilers, or simulation engines. We’re based in Tokyo and this role is on-site. We’ll sponsor your relocation and visa. Our team is international, and we work in English.
