Senior Software Engineer – Systems

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.
