Sophisticated actors systematically front-run all trades (MEV, stat arb), resulting in most high value trading activity remaining within the confines of centralized exchanges that share all the downsides of the system crypto was meant to replace.\nAt Tristero, we're building the world's first performant decentralized darkpool, where your trades are private until they clear, and you maintain full autonomy through the entire trade cycle.\nWhat you'll work on:\nHigh-Performance Matching Engine & Zero-Knowledge Privacy - At the core of our darkpool lies a custom-built, low-latency matching engine that processes orders with microsecond precision while maintaining cryptographic privacy guarantees. You'll work on optimizing order matching algorithms, implementing efficient data structures for order books, and building zero-knowledge proof systems that hide order details until settlement. Our matching engine handles cross-chain order routing across 15+ EVM chains plus Solana, with strict performance targets: Cross-Chain Liquidity Orchestration at Scale - Our liquidity layer intelligently aggregates across Jupiter (Solana), DEX aggregators, Binance, CCTP, and more. You'll build adaptive pathfinding algorithms that dynamically route orders through optimal liquidity sources, implement real-time slippage management systems, and develop cross-chain settlement protocols. The system processes complex multi-hop trades with automatic fallback routing and maintains sub-second response times across 10+ blockchain networks.\nFault-Tolerant Distributed Architecture - Our microservices architecture includes specialized components for real-time pricing, industry-leading order execution, and distributed order routers with Redis-backed state management. You'll work on horizontal scaling patterns, implement circuit breakers and backpressure control, build real-time WebSocket feeds for market data, and design async processing pipelines capable of handling many concurrent orders. All systems include comprehensive telemetry, structured logging, and observability.\nWhat we expect:\n4+ years of professional back-end engineering experience (we’re hiring at multiple seniority levels)\nStrong proficiency with modern back-end systems design\nDeep understanding of API design, databases, and distributed systems\nFamiliarity with DeFi protocols and crypto infrastructure-or a proven ability to ramp up quickly\nStrong ownership of your work\nWe’ve got unlimited PTO, a full suite of healthcare options, and some swag with your name on it. We foster a high-trust, high-autonomy culture. If you’re looking for a no-nonsense team to build groundbreaking financial products with-Tristero may be the place for you.\nWe're looking forward to hearing from you! If you do not have any direct crypto experience, please\nmake sure to include a brief cover letter that explains why you think you can onboard to a new domain smoothly. This can be\nvery short - we do read these.","description_format":"text","description_chars":3147,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Unlimited
