Location: Remote (US preferred) Level: Staff / Principal Competitive base salary ($175K - $225K) We are hiring on behalf of our client, a high-growth, venture-backed crypto company is hiring a Staff Backend Engineer to help build next-generation autonomous trading infrastructure. This is a senior, ownership-heavy role working on real-time trading systems, wallets, and execution infrastructure operating under extreme market conditions. The client is highly responsive and only interviewing candidates who meet all criteria. 🚨 Non-Negotiable Hiring Criteria Candidates must have all of the following: - Hands-on experience with crypto wallets, tokens, and/or trading systems - Deep production experience with Golang, Node.js, and TypeScript - Strong understanding of distributed systems, performance, and reliability - Deep familiarity with trading APIs, execution flows, and transaction lifecycles If any of the above is missing, this role will not be a fit. The Role You’ll own core systems inside the Agent Runtime — the infrastructure that prevents autonomous agents from destroying capital. Specifically: - Hyperfeed data pipeline — executing the enrichment roadmap: OI velocity, funding history, liquidation data, cross-asset flow detection. Server-side computation at scale. - Runtime execution layer — serial signal processing, atomic state management, idempotent order submission, risk enforcement against live exchange state - DSL exit engine — the trailing stop-loss state machine that protects every open position. Two-phase architecture, exchange reconciliation, state recovery - Scanner subsystem — building new scanner types, optimizing the provider layer, wiring new Hyperfeed signals into the confluence scoring system - Learning agent infrastructure — building the systems that let agents observe every trade, identify failure patterns, propose runtime improvements, and launch new experiments autonomously - Scale — taking the runtime from hundreds of agents to tens of thousands
