• Help define engineering best practices in a growing team and contribute to the long-term architecture of our platform

You'll Be Successful in This Role if You Have/Are

• Strong experience writing high-performance systems code, ideally in Zig or similar low-level

• Deep understanding of computer systems, compilers, and performance tuning

• Proven ability to thrive in startups or high-growth environments—comfortable with ambiguity, fast iteration, and rapid scaling

• Excellent written and verbal communication skills, especially when documenting and discussing technical tradeoffs

You May Also Have
