Senior Blockchain Engineer / Protocol Engineer

We’re looking for a Blockchain Engineer with deep expertise in building and deploying blockchain infrastructure—specifically someone capable of architecting and launching an Avalanche Subnet–based Layer 1 blockchain. You’ll own the full lifecycle of our chain: design, configuration, validator orchestration, performance tuning, and long-term maintenance. This is a highly technical role defining the foundation for our protocol.

What You’ll Do

• Design, deploy, and maintain an Avalanche Subnet (custom L1 blockchain).
• Including chain configuration, genesis generation, Subnet-EVM customization, and P-Chain registration.
• Build and extend custom Virtual Machines (VMs) or modify Subnet-EVM parameters to meet product, performance, or economic requirements.
• Stand up validator infrastructure, including node configuration, staking logic, testnet/mainnet deployment, and automated onboarding flows.
• Develop and maintain chain tooling (CLI scripts, SDK integrations, monitoring infrastructure, DevOps pipelines, health checks).
• Design and implement chain-level parameters such as gas strategy, block time, chain ID, fee structure, and upgrade mechanisms.
• Manage end-to-end network lifecycle: local testing, Fuji testnet deployments, migration, validator coordination, and production readiness.

Required Skills & Experience

• 5 years of experience in blockchain engineering, distributed systems, or protocol development.
• Strong proficiency in Golang (Avalanche VMs & node implementations) and familiarity with EVM internals / Solidity tooling.
• Hands-on experience running or developing validators, blockchain nodes, or similar distributed systems.
• Experience deploying and managing Subnets, Cosmos chains, L1/L2 infrastructure, or EVM-based networks.
• Deep understanding of consensus mechanisms, P2P networking, state management, and blockchain security fundamentals.
• Proficiency with DevOps tooling: Docker, Kubernetes, Terraform, CI/CD, observability stacks, reverse proxies, and RPC hardening.
• Experience with cryptography basics: key management, signing, multisig workflows, secure secrets handling.
• Ability to debug performance issues across VMs, RPC layers, networking, and state/database layers (e.g., LevelDB/RocksDB).
• Experience writing reliable documentation, runbooks, and automation scripts.

What We Offer

• Opportunity to design and launch a production-grade, custom L1 blockchain.
• A highly collaborative environment with protocol and product teams.
• Full Healthcare Benefits and unlimited vacation
• Competitive compensation Equity.
• Chance to influence architecture decisions at the earliest stages.
