62 Greenmanpedersen Senior Engineer Jobs Hiring Near You

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 usingGo,Cosmos SDK, andCometBFT (Tendermint)

• Cryptographic Implementation:Implement and optimize privacy-preserving primitives, specificallyPedersen CommitmentsandBulletproofs (Range Proofs), ensuring no trusted setup is required

• Consensus Customization:Engineer customABCI++extensions (specificallyPrepareProposaland Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing network.

• State Machine Design:Design a customKVStorestate 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 inGo (Golang)

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

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

Desired Qualifications:

• Blockchain Core:Deep experience withCosmos SDKandCometBFT. 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 withMPC (Multi-Party Computation)or Verifiable Secret Sharing (VSS) schemes

• Familiarity with theRistretto255curve or libraries likegnark-crypto

• Background in FinTech, payment systems, or high-frequency trading platforms

• Understanding of theAccount Modelvs.UTXO Modeltrade-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
