Unto Labs

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, 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 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.
