Senior Backend Engineer

Skills

About the Role

You will own and evolve the backend infrastructure that powers high-throughput trading: design architecture, build and operate real-time data pipelines, and implement low-latency APIs (GraphQL, WebSockets). You will work directly with ClickHouse, PostgreSQL, and Redis, optimize queries and caching, instrument services with metrics and alerts, participate in on-call rotations, debug latency and memory issues under load, and collaborate with frontend and mobile engineers to serve analytical data via API.

Requirements

• 5+ years of production backend experience (preferably in TypeScript)
• Experience with real-time systems: WebSocket, event streaming, pub/sub
• Deep familiarity with PostgreSQL and Redis; ClickHouse or similar columnar databases a plus
• Track record operating services at scale with high availability requirements
• Understanding of trading concepts: orders, fills, order book, positions, execution
• Experience designing APIs for latency-sensitive, high-throughput clients
• Strong debugging skills including slow queries, memory leaks, and performance profiling

Responsibilities

• Own architecture decisions for backend systems
• Build and operate real-time data pipelines for order book updates, trades, and market events
• Design and maintain the API layer (GraphQL, WebSocket) serving web and mobile clients
• Work with ClickHouse, PostgreSQL, and Redis to handle high-volume trading data
• Optimize query performance, caching, and schema design as data scales
• Instrument services with metrics and alerting and participate in on-call rotations
• Debug latency issues, memory problems, and reliability under load
• Collaborate with frontend and mobile engineers on serving analytical data via API

Benefits

• Equity
• Stipend for remote setup including laptop, peripherals, and work gear
