Back End Node.JS Developer (Remote)

About the Role

• TrendSpider is looking for a seasoned Node.js engineer to help evolve the backend systems that power their trading and analytics platform.
• Work will involve infrastructure behind algorithmic trading tools, data pipelines, backtesting engines, and the custom scripting environment.
• Opportunity to build high-performance systems, wrangle massive data flows, and work close to the markets.

What You’ll Do

• Design, optimize, and maintain Node.js microservices handling tens of thousands of messages per second.
• Connect new data sources and maintain existing ingestion pipelines.
• Improve observability across the data stack—logs, metrics, traces, and alerts.
• Write the business logic that powers charting, scanning, backtesting, and custom scripting.
• Implement automated tests and uphold the standard of clean, maintainable code.
• Manage infrastructure with Terraform—AWS RDS, Lambda, SQS, and related services.
• Work with PostgreSQL and MongoDB directly (no ORMs), scaling both high-read and high-write systems.
• Tune performance and memory efficiency in complex, event-driven systems.
• Collaborate with traders, data scientists, and product teams to translate trading ideas into working software.
• Continuously learn, experiment, and refine how market data and automation come together.

What You Bring

• Deep expertise in Node.js and experience debugging memory leaks, profiling performance, and fixing event-loop jams.
• Experience writing and maintaining Terraform configurations (AWS RDS + Lambda + SQS).
• Solid command of PostgreSQL and MongoDB, handling large-scale datasets efficiently.
• Understanding of both object-oriented and functional programming concepts—and when to use each.
• Familiarity with Kubernetes—at least configuring clusters, bonus points for creating and managing them.
• Comfort working in a microservice architecture (30+ services, all ECMAScript).
• A disciplined approach to testing, CI/CD, container orchestration, monitoring, and alerting.
• A genuine curiosity about markets and trading; hands-on trading or strategy design experience is a major plus.

Why This Role

• Opportunity to build the backbone of a platform used by thousands of serious traders and quants.
• Systems touch real-time data firehoses, multi-terabyte backtests, and live automation.
• A rare chance to combine engineering precision with market intelligence and learn from both worlds.
