Distributed Control System Engineer

Role: Distributed Systems Engineer (Cryptography, Golang, Rust)Location: Concord, CA; Iselin, NJ; Charlotte, NC; Columbus, OHDuration: 12+ MonthsType: Hybrid (3 days onsite & 2 days remote)As a Lead Protocol Engineer, you will contribute to a next-generation Digital Asset Platform and 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.Responsibilities:Architect and build a custom blockchain application using Go, Cosmos SDK, and CometBFT (Tendermint)Implement and optimize privacy-preserving primitives, specifically Pedersen Commitments and Bulletproofs (Range Proofs), ensuring no trusted setup is requiredEngineer custom ABCI extensions (specifically PrepareProposal and Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing networkDesign a custom KVStore state machine that manages homomorphic encrypted balances (Elliptic Curve points) instead of plaintext integersOptimize cryptographic operations (scalar multiplication, point addition) for low latency and high throughput in a distributed environmentBuild secure off-chain query layers and "view key " mechanisms that allow for granular, permissioned regulatory auditingRequirements:5 years of Specialty Software Engineering experience, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education3 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 experienceDesired skills:Deep experience with Cosmos SDK and CometBFT; comfort building custom modules and modifying consensus logic, not just deploying smart contractsPedersen Commitments (Homomorphic encryption properties)Zero-Knowledge Proofs (specifically Bulletproofs or Sigma protocols)Demonstrated ability to read academic whitepapers/preprints and translate mathematical specifications into functioning codeExperience with MPC (Multi-Party Computation) or Verifiable Secret Sharing (VSS) schemesFamiliarity with the Ristretto255 curve or libraries like gnark-cryptoBackground in FinTech, payment systems, or high-frequency trading platformsUnderstanding of the Account Model vs. UTXO Model trade-offs in privacy-preserving ledgers
