Responsibilities
Core Protocol Development: Architect and build a custom blockchain application using Go, Cosmos SDK, and CometBFT (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 PrepareProposal and Vote Extensions) to implement an on-chain Multi-Party Computation (MPC) mixing network
State Machine Design: Design a custom KVStore 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
Qualification
Required
4+ 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
Preferred
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)
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
