Lead Cryptography Engineer (MPC & Confidential Computing)

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).

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 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
• Understanding of the Account Model vs. UTXO Model trade-offs in privacy-preserving ledgers
