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 Comet. BFT (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 Prepare. Proposal and Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing network. State Machine Design: Design a custom KV - Store state 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 in Go (Golang)Applied Cryptography: 6 months of experience with Elliptic Curve Cryptography (ECC)Distributed Systems: 1 year of experience with BFT consensus algorithms, P 2 P networking, and state replication. Desired Qualifications:Blockchain Core: Deep experience with Cosmos SDK and Comet. BFT. 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 Ristretto 255 curve or libraries like gnark-crypto. Background in Fin. Tech, payment systems, or high-frequency trading platforms. Understanding of the Account Model vs. UTXO Model trade-offs in privacy-preserving ledgers.
