Senior Full-Stack Real-Time Systems Engineer

This a Full Remote job, the offer is available from: United States At Tradeify.co, we are a fintech company developing sophisticated infrastructure for real-time data analysis and decision-making. This is not a typical web app role — it’s about designing and delivering mission-critical, multi-service systems that power sophisticated, large-scale data processing. We’re looking for a pragmatic engineer who can integrate into a team, follow sprint ceremonies, and deliver high-quality code under pressure. We value collaboration, process, and accountability over lone-wolf coding. A competitive compensation package will be offered to the successful candidate. What You’ll Do • Design and maintain multi-region microservices that ingest, deduplicate, and replay futures market data streams with sub-millisecond ordering guarantees. • Build a hybrid persistence layer leveraging PostgreSQL, TimescaleDB, Redis, and ClickHouse and know when to apply each in real time. • Architect backpressure-aware pipelines across Kafka, NATS, and Pulsar simultaneously, with seamless failover strategies. • Implement an AI and anomaly detection service consuming millions of events per second without packet loss. • Deliver a multi-monitor Electron desktop shell embedding a proprietary charting platform, with hot-reloading and drag-drop layout persistence. • Collaborate in a Scrum sprint process: participate in planning, estimation, stand-ups, and retrospectives. • Write integration harnesses that simulate exchange disconnects, order fills, tick sequence gaps, and user recovery scenarios. What You’ll Bring • 5+ years of engineering experience across Go, Rust, Node.js, TypeScript, Kotlin, and C++, with production code in all of them. • Deep expertise in WebSockets, gRPC, FIX, and custom binary protocols. • Prior experience in high-frequency trading. • Proven ability to ship React/Electron apps with real-time state synchronization across thousands of widgets. • Experience running stateful microservices with rolling upgrades and zero downtime. • Working knowledge of Scrum/Agile, delivering increments under tight deadlines and stress. • Ability to thrive under pressure, communicate clearly, and collaborate with teammates rather than work in isolation. Bonus Points • Built or operated Kafka clusters moving >10M events/sec. • Familiar with CRDTs vs Lamport clocks for ordering ticks across unreliable streams. • Implemented your own message broker or time-series database “for fun.” • Strong awareness of WCAG AA accessibility in multi-pane trading dashboards. • Deployment experience across AWS, GCP, Azure, and bare-metal Kubernetes simultaneously.
