About The Position

Genesis10 is seeking a Lead Protocol Engineer for a hybrid role with a Global Financial Institution in Iselin, NJ. This is a 12+ month contract opportunity. The role involves contributing to a next-generation Digital Asset Platform and architecting the core settlement engine. The engineer will work at the intersection of distributed systems and applied cryptography, translating complex mathematical proofs into high-performance, production-grade Go code.

Requirements

5 years of Specialty Software Engineering experience, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education
3 years of experience in backend or systems programming, with expert-level proficiency in Go (Golang)
6 months of experience with Elliptic Curve Cryptography (ECC)
1 year of experience with BFT consensus algorithms, P2P networking, and state replication; reliable, distributed systems experience

Nice To Haves

Deep experience with Cosmos SDK and CometBFT; comfort building custom modules and modifying consensus logic, not just deploying smart contracts
Pedersen Commitments (Homomorphic encryption properties)
Zero-Knowledge Proofs (specifically Bulletproofs or Sigma protocols)
Demonstrated ability to read academic whitepapers/preprints and translate mathematical specifications into functioning code
Experience with MPC (Multi-Party Computation) or Verifiable Secret Sharing (VSS) schemes
Familiarity with the Ristretto255 curve or libraries like gnark-crypto
Background in FinTech, payment systems, or high-frequency trading platforms
Understanding of the Account Model vs. UTXO Model trade-offs in privacy-preserving ledgers

Responsibilities

Architect and build a custom blockchain application using Go, Cosmos SDK, and CometBFT (Tendermint)
Implement and optimize privacy-preserving primitives, specifically Pedersen Commitments and Bulletproofs (Range Proofs), ensuring no trusted setup is required
Engineer custom ABCI extensions (specifically PrepareProposal and Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing network
Design a custom KVStore state machine that manages homomorphic encrypted balances (Elliptic Curve points) instead of plaintext integers
Optimize cryptographic operations (scalar multiplication, point addition) for low latency and high throughput in a distributed environment
Build secure off-chain query layers and "view key" mechanisms that allow for granular, permissioned regulatory auditing

Benefits

Access to hundreds of clients, most who have been working with Genesis10 for 5-20+ years.
The opportunity to have a career-home in Genesis10; many of our consultants have been working exclusively with Genesis10 for years.
Access to an experienced, caring recruiting team (more than 7 years of experience, on average.)
