Jobs at Ledgeroom

Develop end-to-end decentralized applications, building React and Next.js interfaces, Node.js backend services, REST APIs, wallet integrations, and smart-contract interactions. Responsibilities include indexing blockchain data, processing transactions, managing off-chain logic, securing private keys, and delivering user-friendly Web3 experiences in collaboration with product and design teams.

Build high-load, low-latency Rust backend services for Solana transaction simulation, validation, block building, and lifecycle management. Develop integrations with DEXs, bridges, and staking protocols; create APIs and operational tooling; optimize for throughput, fault tolerance, and observability; and work with PostgreSQL and Redis. Requires production Rust experience, Web3 expertise, blockchain cryptography knowledge, and familiarity with Docker and monitoring tools.

Develop and maintain Python-based blockchain components, smart contracts, APIs, microservices, credentialing systems, and node infrastructure for an educational platform. Integrate with LMS platforms, manage wallets and keys, support CI/CD, document the system, train staff, and ensure FERPA/GDPR-compliant data handling.

Design, implement, deploy, test, audit, and monitor production Solidity smart contracts for DeFi protocols. Lead architecture decisions, security reviews, deployment automation, and CI pipelines while collaborating with auditors, researchers, and frontend engineers. Review code, mentor engineers, translate protocol specifications into gas-efficient implementations, and stay current with EVM changes, standards, and vulnerability classes.

Develop and maintain privacy-focused protocol and wallet infrastructure in modern C++. Responsibilities include implementing transaction, consensus, and P2P components; integrating cryptography; supporting cross-platform libraries and CLIs; writing tests and fuzzers; optimizing performance; addressing side-channel risks; and documenting auditable designs. The role requires collaboration with cryptographers and protocol researchers on secure, reliable blockchain-related systems.
