• Drive architectural decisions across core infrastructure codebases, contributing to Ethereum-aligned and Cosmos‑based systems where needed.
• Investigate and resolve deep technical issues in consensus mechanisms, protocol behavior, and state synchronization.
• Champion engineering best practices, including code quality, documentation, automated testing, and performance optimization.
• Mentor and support engineers across the stack, elevating technical standards and fostering a culture of excellence.
• Collaborate cross‑functionally with protocol researchers, DevOps, security, and ecosystem teams to deliver safe, reliable network upgrades.

Requirements

• 7+ years of experience in backend or protocol engineering, including 2+ years in senior or staff‑level roles.
• Deep expertise in Golang and hands‑on experience building distributed systems, consensus mechanisms, or blockchain infrastructure.
• Proven background contributing to or working with Ethereum clients, Cosmos SDK, CometBFT, or similar protocol frameworks.
• Strong ability to lead architecture, complex system design, and large‑scale performance optimization initiatives.
• Excellent problem‑solving, communication, and documentation skills, with comfort working asynchronously across distributed teams.
• Preferred qualifications include open‑source protocol contributions, experience with large‑scale performance tooling, and strong interest in decentralized technologies and Ethereum‑aligned systems.

Benefits

• Fully remote, global‑first work environment.
• Comprehensive medical, dental, and vision healthcare coverage, depending on country and plan.
• Company‑matched retirement plan where applicable.
• Home office setup allowance and monthly internet or phone reimbursement.
