We are seeking a highly skilled Blockchain Developer with 3+ years of hands-on experience writing Solidity smart contracts for EVM-compatible chains and 2+ years building blockchain clients or cryptographic libraries in Rust. You'll help evolve our Ethereum-forked, PoS consensus layer, secure key-management tooling, validator deployment pipelines, and staking-deposit CLI

Key Responsibilities

  • Develop and maintain our consensus client (Rust) powering block proposal, attestations, and fork-choice logic
  • Harden our node-setup tooling (Bash/Ansible/Docker) for turnkey validator deployment
  • Extend the wagyu-key-gen library (Rust) for secure BLS key generation & threshold signatures
  • Build & support the Staking-Deposit-CLI (Node.js/ethers.js) to batch ETH/ERC-20 deposits
  • Audit and author Solidity contracts for token economics, governance modules, and bridge logic
  • Collaborate on consensus upgrades, testnet launches, and mainnet hard forks
  • Write unit & integration tests and automate CI/CD pipelines for zero-downtime upgrades
  • Optimize P2P networking, slot-timing, and validator liveness under high throughput

Required Skills & Experience

3+ years writing Solidity smart contracts on Ethereum or EVM-compatible chains

2+ years building blockchain clients or cryptographic libraries in Rust

Deep understanding of PoS consensus protocols (Beacon chain, fork choice, attestations)

Experience building Node.js CLI tools with ethers.js, yargs, dotenv

Solid grasp of BLS signature schemes, HD key derivation, and secure key-management

Linux server administration, Docker, and scripting for automated node provisioning

Proven track record in open-source blockchain contributions or running validator nodes

Strong testing discipline: unit tests, fuzzing, CI/CD (GitHub Actions, GitLab CI, etc.)

Nice to Have (Bonus Skills)

Hands-on experience with cross-chain bridges or Layer-2 rollups

Knowledge of libp2p, gRPC, or custom P2P protocols

Prior work on staking-deposit contracts or validator dashboards

Contributions to Ethereum Foundation, Polkadot, Cosmos, or similar ecosystems

Performance tuning in Rust (async, Tokio, CPU profiling)

Kubernetes or Terraform experience for large-scale validator clusters

Who We're Looking For

A proactive problem-solver passionate about decentralized systems, eager to own critical components of our PoS stack, and comfortable collaborating in a fast-paced environment.

We encourage applications only from candidates who feel this role is the right fit. If you meet these requirements and are excited to push the boundaries of PoS blockchains, we'd love to hear from you
