About the role

Key responsibilities & impact

Design, implement, and maintain core components of the GraphTally protocol in Rust.
Collaborate with researchers and protocol engineers to refine and evolve the architecture.
Optimize signature verification, message processing, and batching for high-throughput performance.
Implement secure state transition logic, trust-minimized payment flows, and smart contract interactions.
Work closely with smart contract engineers to ensure seamless on-chain integration (mainly on L2s like Arbitrum).
Write clean, testable, and efficient code with a focus on security and correctness.
Contribute to technical documentation, specifications, and developer tooling to support GraphTally adoption.

Requirements

What you’ll need

3+ years of professional experience writing high-performance, production-quality async code in Rust.
Experience in designing and implementing remote APIs (REST, JSON-RPC, gRPC)
Experience in responsive microservices design and development
Experience with databases (Postgres, Redis)
Experience with Docker.
Deep understanding of cryptographic primitives, especially ECDSA and digital signature schemes.
Proficient with Rust’s async/await model, leveraging futures, tokio, or async-std
Understanding of asynchronous state machines for managing complex protocol flows
Familiarity with zero-knowledge proofs, state/payment channels, or escrow mechanisms is a plus.
Strong grasp of trust-minimized systems, distributed protocols, or payment rails in a web3 context.
Experience working with Ethereum L2s (like Arbitrum, Optimism) and integrating with smart contracts.
Proficiency with testing, benchmarking, and debugging asynchronous Rust applications in the context of web3, using tools like anvil.
Clear communication, curiosity, and a strong sense of ownership.
