Senior Validator Engineer (Remote - EU)

This is a remote position.

The company develops a coordination layer and infrastructure protocol built on Solana that enhances network performance, reliability, and scalability. The platform introduces novel transaction types, mitigates MEV, and enables customizable execution environments through features like edge compute zones, guaranteed transaction inclusion, and deterministic execution. It solves a fundamental coordination problem with distributed networks, making crypto apps as powerful, fast, and precise as traditional tech systems.
