Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Lead Protocol Engineer (Go / Cryptography) - **Company:** Wells Fargo - **Location:** Woodbridge Township, NJ, United States - **Experience:** Expert - **Salary:** $159,000.0 - $305,000.0 - **Contract:** Permanent contract - **Skills:** Software Design Patterns, Digital Assets, Distributed Systems, Payment Systems, High-Frequency Trading, Blockchain, Software Engineering, System Programming, State Machines, Backend, Low Latency, Golang - **Published:** August 3, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=355d1acc9a6b55dc ## About the Role * 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 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 ## Description 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 ## Related Videos - [Future-Proofing FinTech With Blockchain Technology](https://www.wearedevelopers.com/videos/808-future-proofing-fintech-with-blockchain-technology) - [Pragmatic Blockchain Design Patterns: Integrating Blockchain into Business Processes](https://www.wearedevelopers.com/videos/1579-pragmatic-blockchain-design-patterns-integrating-blockchain-into-business-processes) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Scoring 2000 Products per Request: Performance Pitfalls in Golang](https://www.wearedevelopers.com/videos/2073-scoring-2000-products-per-request-performance-pitfalls-in-golang) - [Develop a Blockchain Application in JavaScript with Lisk SDK](https://www.wearedevelopers.com/videos/188-develop-a-blockchain-application-in-javascript-with-lisk-sdk) ## Related Articles - [From Hype to Code: Real Blockchain Use Cases for Developers](https://www.wearedevelopers.com/magazine/620-from-hype-to-code-real-blockchain-use-cases-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Why Blockchain?
