Protocol Engineer; Golang

We are seeking an experienced Lead Specialty Software Engineer (Protocol Engineer) to design, develop, and optimize a next-generation Digital Asset Platform supporting secure, confidential, and regulatory-compliant institutional financial transactions.

The ideal candidate will have strong experience in Golang, distributed systems, blockchain protocols, elliptic curve cryptography, and consensus algorithms.

This role involves architecting a blockchain settlement engine, implementing privacy-preserving cryptographic solutions, and developing high-performance distributed applications.

• Golang (Go): 3+ years of backend or systems programming experience, with expert-level Go development skills.
• Elliptic Curve Cryptography (ECC):
  Minimum 6 months of hands‑on experience implementing or working with ECC.
• Distributed Systems: 1+ year of experience with BFT consensus algorithms, peer‑to‑peer networking, and state replication.
• Software Engineering: 5+ years of professional software engineering experience.
• Database Technologies:
  YugabyteDB, PostgreSQL, and/or Liquibase, as highlighted in the top skills.

• Design and develop custom blockchain applications using Golang, Cosmos SDK, and CometBFT (Tender mint).
• Build and optimize core blockchain settlement protocols for institutional financial transactions.
• Implement cryptographic techniques such as Pedersen Commitments and Bulletproofs (Zero‑Knowledge Range Proofs).
• Develop custom ABCI++ extensions, including Prepare Proposal and Vote Extensions.
• Implement Multi‑Party Computation (MPC) mixing networks.
• Design KVStore‑based state machines supporting encrypted balances.
• Optimize elliptic curve operations, including scalar multiplication and point addition.
• Develop secure off‑chain query mechanisms and permission‑based regulatory auditing capabilities.
• Ensure high availability, low latency, scalability, and transaction confidentiality.

• Hands‑on experience with Cosmos SDK, CometBFT, or Tender mint.
• Knowledge of Zero‑Knowledge Proofs (ZKP), Bulletproofs, and Sigma protocols.
• Experience with Pedersen Commitments and homomorphic encryption.
• Familiarity with Multi‑Party Computation (MPC) and Verifiable Secret Sharing (VSS).
• Experience with Ristretto
  255 or gnark‑crypto.
• Strong understanding of blockchain consensus architecture.
• Ability to translate mathematical research papers into production‑grade code.
• Knowledge of Account Model versus UTXO Model.
• Experience in financial services, Fin Tech, payments, or trading platforms.
