Braid Technologies

We are developing a cutting-edge platform for automated advanced engineering design that transforms high-level problem descriptions into geometry that is optimized and ready for manufacturing. Consider: not just code, but compilers for physics problems. To assist us in developing our core stack, which includes high-performance geometry kernels and DSL compilers, we are seeking senior systems engineers with solid backgrounds in computer science. A close-knit, highly technical team with expertise in physics, mathematics, compilers, C++, Rust, and optimization will be yours to join. You will be working on systems-level architecture and backend infrastructure; high-performance geometric algorithms (meshing, optimization, constraints); a bespoke compiler stack for our engineering DSL; and cooperative work with academics, designers, and domain specialists. 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. Our team is international, and we work in English.
