Job description

Position: Blockchain / Protocol Engineer
Location: Iselin NJ
Duration: Contract
Job ID: 177733
Only W2
Are you passionate about blockchain protocols, distributed systems, and applied cryptography? We are seeking a Lead Protocol Engineer to help build a cutting-edge Digital Asset Platform focused on solving one of the biggest challenges in institutional finance-delivering regulatory compliance while preserving transaction confidentiality.
This role sits at the intersection of cryptography, blockchain infrastructure, and high-performance distributed systems, offering the opportunity to design and develop core protocol components from the ground up.
Key Responsibilities
Core Protocol Development
  • Architect and develop a custom blockchain application using Go (Golang), Cosmos SDK, and CometBFT (Tendermint).
  • Design scalable and secure protocol components for institutional-grade digital asset settlement.
Cryptographic Engineering
  • Implement and optimize privacy-preserving cryptographic primitives including:
  • Pedersen Commitments
  • Bulletproofs (Range Proofs)
  • Ensure cryptographic solutions operate without requiring a trusted setup.
Consensus & Distributed Systems
  • Develop custom ABCI++ extensions including:
  • Prepare Proposal
  • Vote Extensions
  • Build and support an on-chain Multi-Party Computation (MPC) mixing network.
State Machine Design
  • Design and maintain custom KVStore state machines.
  • Manage homomorphically encrypted balances using Elliptic Curve cryptography rather than traditional plaintext accounting models.
Performance Optimization
  • Optimize cryptographic operations such as:
  • Scalar multiplication
  • Point addition
  • Improve throughput, latency, and scalability across distributed environments.
Regulatory Auditing Infrastructure
  • Develop secure off-chain query layers.
  • Implement \"view key\" mechanisms enabling permissioned regulatory oversight while maintaining privacy.
Required Qualifications:
  • 5+ years of Software Engineering experience.
  • 3+ years of backend or systems programming experience.
  • Expert-level proficiency in Go (Golang).
  • 1+ year of experience building reliable distributed systems.

Experience with:
  • BFT Consensus Algorithms
  • P2P Networking
  • State Replication
  • 6+ months of hands-on experience with Elliptic Curve Cryptography (ECC).
  • Strong understanding of distributed architecture, performance optimization, and systems design.

Ideal Candidate:
  • Deep interest in blockchain protocol development.
  • Experience building low-level distributed systems.
  • Strong understanding of applied cryptography and privacy-preserving technologies.
  • Ability to translate mathematical concepts into production-grade software.
  • Comfortable operating in highly complex, research-driven engineering environments.

Preferred Experience:
  • Cosmos SDK
  • CometBFT / Tendermint
  • Blockchain protocol engineering
  • MPC (Multi-Party Computation)
  • Zero-Knowledge Proofs (ZKP)
  • Cryptographic protocol implementation
  • Financial services, digital assets, or fintech platforms
