SeniorSpecialtyProtocolEngineer

**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. As a Senior Protocol Engineer, you will be responsible for architecting the core settlement engine. You'll work at the intersection of distributed systems and applied cryptography, translating complex mathematical proofs into high-performance, **production-grade Go code**. **Why apply to this job?** * **To work on complex problems:** You won't be building another yield farm copycat. You'll be solving 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 sta
