Remote | Full-time

Compensation: $75K - $85K

Our client is a fast-growing, enterprise-grade software organization committed to supporting, developing, and servicing a leading open-source, proof-of-stake distributed ledger platform. As an EVM-compatible network built to meet the rigorous demands of global developers and institutions, the platform prioritizes speed, security, stability, and sustainability, and is governed by industry-leading organizations across multiple sectors and regions.

As the platform scales with new protocol upgrades, EVM-compatible services, cross-chain infrastructure, and cryptographic primitives, managing the expanding attack surface is paramount. The Product Security Engineer will be responsible for embedding security directly into the product development lifecycle, ensuring that security remains a first-class property of every protocol upgrade, smart contract, and node shipped to production. This role focuses on hands-on vulnerability discovery, adversarial testing, and proactive threat mitigation before code reaches production.
