Unto Labs | Systems Engineer | San Francisco, CA | ONSITE (Hybrid OK), REMOTE (US) | Full-Time | https://jobs.ashbyhq.com/unto-labs/13df6bea-b253-4c80-ae05-5...

We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers. Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. Components are developed in C for maximal control over performance and resource usage.

Interesting problems you’ll tackle:

- Building and testing high-performance subsystems in C (cryptographic routines, consensus primitives, networking protocols)

- Designing robust process isolation on modern CPU architectures and tile-based multi-core layouts

- Optimizing memory hierarchies, cache utilization, and low-level I/O for commodity servers

You:

- 5+ years of systems programming in C/C++, Rust, or similar

- Deep expertise in CPU microarchitecture, memory subsystems, and low-level performance tuning

- Strong understanding of distributed systems design and consensus protocols

- Experience with high-performance networking and protocol design in real-time environments
