Wells Fargo is seeking a Lead Specialty Software Engineer (Protocol Engineer) 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. As a Lead Protocol Engineer, you will be responsible for architecting the core settlement engine. You will work at the intersection of distributed systems and applied cryptography, translating complex mathematical proofs into high-performance, production-grade Go code.
Why Join Us?
- Work on "Hard" Problems: You won't be building another yield farm copycat. You'll solve fundamental privacy/compliance contradictions in the global financial system
- High-Impact Engineering: Your code will secure high-value institutional transactions
- Technical Autonomy: You'll play a key role in architectural decisions, choosing the right curves, libraries, and design patterns
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:
- 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 withBFT consensus algorithms, P2P networking, and state replication; reliable, distributed systems experience
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
Job Expectations:
- This position offers a hybrid work schedule
- Relocation assistance is not available for this position
Locations:
- 194 Wood Ave S, Iselin, New Jersey
- 3075 Loyalty Circle, Columbus, Ohio
- 1755 Grant Street, Concord, California

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
