About The Position

zerohash is seeking an Integration Engineer for its Implementation Services Team. The role leads end-to-end technical execution and onboarding for high-value institutional deals, from technical kickoff through production go-live. It focuses primarily on Central Limit Order Book (CLOB) FIX connectivity and related digital-asset infrastructure, including account funding and payouts, crypto deposits and withdrawals, Request for Quote (RFQ), and staking services. The engineer works directly with client technical teams on integration architecture, testing, API/FIX setup, and go-live readiness. Success is measured by rapid time to production, smooth implementations, and reliable integrations that generate business volume. The role reports to the Head of Implementation Services and is fully remote for candidates based in the United States and/or Canada.

• Hands-on proficiency with REST, WebSockets, JSON/HTTP, and distributed architecture patterns.
• Hands-on SQL experience and proficiency in at least one programming or scripting language: Python, JavaScript/TypeScript, Go, or Java.
• A proven track record of managing technical implementations from kickoff through production launch under tight timelines.
• Ability to lead technical working sessions with client developers, system architects, and technical project managers.
• Strong analytical and troubleshooting skills for real-time order-flow issues, ledger adjustments, and protocol discrepancies across complex multi-product environments.

Nice To Haves

• Direct experience with Order Management Systems (OMS), Execution Management Systems (EMS), Central Limit Order Books (CLOB), or matching-engine connectivity.
• Experience implementing digital-asset custody, crypto rails, deposit/withdrawal sweeping, yield or staking protocols, or fiat payout gateways.
• Experience working alongside prime brokers, proprietary trading desks, fintech brokers, or institutional crypto exchanges.
• Experience using AI-assisted tools for learning, log analysis, code generation, and implementation troubleshooting.

Responsibilities

• Lead end-to-end technical integration workflows for deals approaching contract execution through production go-live.
• Serve as the technical point of contact for clients integrating through CLOB FIX protocols and REST/WebSocket APIs.
• Guide institutional clients through implementing account funding, payouts, crypto deposits and withdrawals, RFQ, and staking products.
• Lead client engineering teams through sandbox environments, connection configuration, order-flow validation, edge-case testing, and production deployment.
• Diagnose, debug, and resolve implementation blockers, API errors, payload misconfigurations, and connectivity issues.
• Partner with Sales, Solutions Engineering, Product, and Core Engineering to hand off client requirements and accelerate features needed for go-live.
• Improve implementation playbooks, client integration documentation, and automated testing tools to shorten onboarding timelines.
