Engineering$119k–$224k/yrFull-time

About This Role

Wells Fargo is seeking several Senior Specialty Software Developers (Protocol Engineers) to contribute to a next-generation Digital Asset Platform designed to solve the most critical challenge in institutional finance: achieving strict regulatory compliance without compromising transaction confidentiality. Wells Fargo is moving beyond standard public blockchains to build a custom, application-specific infrastructure. Our platform utilizes advanced cryptography to enable "auditable privacy"-allowing regulated institutions to settle digital assets securely while preserving strategic confidentiality, without relying on centralized intermediaries.

Responsibilities

  • Core Protocol Development: Architect and build a custom blockchain application using Go, Cosmos SDK, and CometBFT (Tendermint)

  • Cryptographic Implementation: Implement and optimize privacy-preserving primitives, specifically Pedersen Commitments and Bulletproofs (Range Proofs), ensuring no trusted setup is required

  • Consensus Customization: Engineer custom ABCI++ extensions (specifically PrepareProposal and Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing network

  • State Machine Design: Design a custom KVStore state machine that manages homomorphic encrypted balances (Elliptic Curve points) instead of plaintext integers

  • Performance Engineering: Optimize cryptographic operations (scalar multiplication, point addition) for low latency and high throughput in a distributed environment

  • Auditing Infrastructure: Build secure off-chain query layers and "view key" mechanisms that allow for granular, permissioned regulatory auditing

Required Qualifications

  • 4+ years of Specialty Software Engineering experience, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education

  • Systems Engineering: 3+ years of experience in backend or systems programming, with expert-level proficiency in Go (Golang)

  • Applied Cryptography: 6+ months of experience with Elliptic Curve Cryptography (ECC)

  • Distributed Systems: 1+ year of experience withBFT consensus algorithms, P2P networking, and state replication

Desired Qualifications

  • Blockchain Core: 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)

  • Math-to-Code: 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
