Senior Validator Engineer (Solana)

Location: Remote - Europe only

Compensation: $180K - $300K

We are reengineering blockchain infrastructure from first principles to make global digital markets as precise and dependable as physical systems. Built on Solana, our platform delivers deterministic execution, guaranteed inclusion, and low-latency performance—solving the foundational failures that cause transactions to miss and systems to collapse under pressure.

By placing high-performance compute close to where transactions happen and coordinating execution through our advanced scheduling engine, we empower developers to build scalable applications and give institutions the reliability they demand. 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.
