I’m currently working with an early stage blockchain infrastructure company preparing for mainnet launch who are looking for a Head of Protocol Engineering to lead the design, build, and scale of a genuinely differentiated blockchain architecture.

 

This is a pivotal role reporting directly to the CTO, owning the core protocol stack and leading a small but highly capable engineering team. The business is building a new approach to on-chain data accessibility, removing the need for indexers and external query infrastructure through protocol-native architecture.

 

You’ll remain hands-on technically while driving engineering standards, roadmap execution, and team growth.

 

This is a rare opportunity to join at the right stage and shape both the technology and engineering culture of a protocol with significant upside.

 

Responsibilities

  • Own protocol engineering across nodes, storage systems, smart contracts, SDKs, and L2/L3 integrations.
  • Lead development of modified execution clients and queryable storage systems.
  • Drive performance optimisation across high-throughput distributed systems and database workloads.
  • Partner with the CTO on technical strategy, hiring plans, and roadmap execution.
  • Lead, mentor, and grow a team of engineers while staying close to the codebase.
  • Own protocol specs, developer tooling, and technical documentation standards.
  • Support production incidents where needed and continuously improve system reliability.

 

Requirements

  • Strong background in systems programming using Rust.
  • Deep distributed systems knowledge including consensus, replication, and failure modes.
  • Experience working on blockchain nodes, execution clients, or protocol-level systems.
  • Strong understanding of databases, storage engines, and query optimisation under load.
  • Previous leadership experience managing and growing engineering teams.
  • Hands-on mindset with the ability to lead while actively shipping code.
  • Excellent communication skills and ability to operate in a fast-moving environment.
