We are building a next-generation decentralized exchange with a fully on-chain order book. Our system is built with a custom state transition function and consensus layer, purpose-designed for high-performance, low-latency trading. The goal is to deliver a trustless platform that matches the speed and efficiency of traditional trading engines while providing full transparency by running execution as close as possible to the blockchain itself.\nPosition Overview\nWe are looking for a Senior Rust Engineer with strong expertise in system architecture and execution engines. You will be responsible for designing and implementing the CLOB execution layer, including the order book, matching engine, and blockchain client logic. This role is highly technical and requires end-to-end ownership of critical components, from architecture to optimization. While you’ll primarily collaborate with a remote team of experienced engineers, there will occasionally be opportunities to work onsite during offsite sessions to support onboarding and enable more efficient collaboration.\nJoining at this early stage of development offers a unique opportunity to influence critical technical decisions, achieve career growth, and enjoy competitive compensation.\nKey Responsibilities\nArchitect and implement the on-chain order book and matching engine in Rust.\nDesign and extend exchange-specific logic (order execution, risk checks, account/state management).\nDesign and develop protocol-level components, such as state transition logic, consensus, validator interaction, and transaction processing pipelines.\nImplement integration with oracles, bridges, and external data providers, ensuring correctness and resilience in adversarial conditions.\nOptimize for low-latency execution, concurrency, and gas efficiency.\nConduct benchmarking and stress testing to identify and address potential performance/throughput bottlenecks.\nDevelop and maintain a comprehensive suite of unit, integration, and end-to-end tests to ensure code reliability and functionality.\nRequirements\n5+ years of systems programming experience, with 3+ years in Rust.\nProven track record building trading platforms, execution engines, or exchanges (DEX or centralized).\nContributions to Rust-based L1 protocol projects (e.g., Solana, Cosmos SDK, Substrate).\nDeep understanding of distributed computing principles, including consensus algorithms, peer-to-peer (P2P) networking, and high-performance data structures.\nDeep knowledge of decentralized trading models (on-chain order books, AMMs, hybrid architectures).\nAbility to design and implement complex, production-grade systems independently.\nBig Bonus\nExperience with competitive programming or algorithmic problem solving.\nExpertise in low-latency design, concurrency, and performance optimization.","description_format":"text","description_chars":3073,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Japan","iso":"JP","kind":"country"},{"name":"Singapore","iso":"SG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain
