Full Job Description
About this Role:

Wells Fargo is seeking a Lead Specialty Software Engineer (Cryptography 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 Cryptography Engineer you will be responsible for architecting the core Key Management Service (KMS). You will sit at the intersection of applied cryptography, hardware security, and distributed systems, implementing threshold signing protocols inside attested execution environments.

Responsibilities:
  • MPC Protocol Implementation: Architect and implement high-performance threshold signature schemes (specifically DKLS23 or similar) for ECDSA key generation and signing
  • Confidential Computing Architecture: Design and build services that run inside Trusted Execution Environments (TEEs), specifically targeting AMD SEV-SNP and Intel TDX via Confidential Containers (CoCo)
  • Attestation Framework: Implement the RATS (Remote ATtestation procedureS) architecture (RFC 9334) to ensure that no key share is released until the requesting node proves its hardware and software integrity to a Key Broker Service
  • Hardware Security Integration: Design "Cold Ceremony" workflows that integrate offline hardware tokens as offline Key Encryption Keys (KEKs) for disaster recovery and deep storage
  • Secure Enclave Development: Write and optimize memory-safe code (Rust/Go) that operates on key material exclusively within encrypted memory regions, ensuring zero leakage to the host OS or hypervisor
  • Policy-to-Cryptography Binding: Design mechanisms to cryptographically bind business logic approvals (e.g., WebAuthn assertions) directly to the MPC signing session, eliminating the gap between "approval" and "execution"


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
