Senior Validator Engineer (Solana)

We are reengineering blockchain infrastructure from first principles to make global digital markets as precise and dependable as physical systems.

We believe financial infrastructure should behave like physics: fast, reliable, and predictable—every time, without exception.

As a Senior Validator Engineer, you will spearhead our engineering efforts surrounding the Solana Validator (both Agave and Firedancer), driving the innovation and implementation of next-generation high-performance distributed systems. You will join a highly proficient team of core engineers who have all contributed to foundational network components.
