Job Description

• Design, implement, and operate the core software of the Moca Chain—focusing on reliability, performance, and the identity‑specific features of our L1. • Work on client/runtime components, networking, cross‑chain identity flows, and ZK integrations that enable private verification at scale. • Partner with protocol researchers, ZK engineers, and infra/DevOps to run testnets, ship upgrades, and launch features like zkTLS proofs, verifiable credential issuance/verification, and our identity oracle.

Job Requirements

Strong systems engineering in Go or Rust (or similar); solid concurrency/async, profiling, and performance tuning skills.
Experience building backend or protocol‑adjacent infrastructure that runs in production.
Practical familiarity with blockchain client internals (any of: EVM/WASM runtime, Cosmos SDK/Substrate modules, or rollup nodes).
Comfortable with Web3 interfaces and ops: RPCs (JSON‑RPC/gRPC), node configuration, validator/sequencer operations, snapshots/state sync.
Sound engineering practices: testing, code reviews, CI/CD, reproducible builds, and clear documentation.
Security mindset: input validation, DoS/eclipse awareness, rate‑limiting, key management basics.
Nice-to-haves: Zero‑knowledge integration experience (using/verifying proofs, e.g., PLONK/Groth16/FRI) or prior work on verifier precompiles.
Exposure to identity/credentials standards (VCs/VPs), replay protection, nonce/sequence management, and capability/permissions models.
Cross‑chain experience: light clients, optimistic/validity bridges, IBC/XCM, or L1↔L2 messaging.
Database/storage tuning in high‑throughput chains; experience with state growth and archive modes.
Contributions to open‑source blockchain clients or identity/zk tooling.
