Node Engineer / Backend

We are a venture-backed fintech company building a next-generation platform for automated technical analysis and trading workflows. Our software brings institutional-grade analytics-pattern recognition, signal generation, backtesting, and automated execution-to professional traders, quantitative analysts, and investment teams.

We're looking for a senior Node.js engineer to help evolve the backend systems that power a high-performance trading and analytics platform. You'll work on the infrastructure behind algorithmic trading tools, data ingestion pipelines, large-scale backtesting engines, and a custom scripting environment used by thousands of active market participants.

Required Skills & Experience

• Design, optimize, and maintain Node.js microservices processing tens of thousands of messages per second
• Build and maintain data ingestion pipelines for market, fundamental, and alternative datasets
• Improve observability across the platform (logging, metrics, tracing, alerting)
• Implement the business logic behind charting, scanning, backtesting, and scripting engines
• Write clean, well-tested, and maintainable code with a strong focus on performance
• Manage cloud infrastructure using Terraform, including AWS-managed services
• Work directly with PostgreSQL and MongoDB (no ORMs), scaling both read- and write-heavy workloads
• Diagnose and resolve performance bottlenecks, memory leaks, and event-driven system issues
• Partner with cross-functional teams to translate trading ideas into production-grade software
• Continuously experiment, learn, and refine how market data and automation intersect

Desired Skills & Experience

• Deep experience with Node.js, including performance profiling, memory management, and event-loop optimization
• Hands-on experience managing infrastructure as code with Terraform (AWS RDS, Lambda, SQS, etc.)
• Strong working knowledge of PostgreSQL and MongoDB at scale
• Solid grasp of object-oriented and functional programming paradigms-and when to use each
• Familiarity with Kubernetes (configuring clusters required; building and managing clusters is a plus)
• Experience working in a microservices architecture with many independently deployed services
• A disciplined engineering mindset around testing, CI/CD, containerization, monitoring, and alerting
• Genuine curiosity about financial markets and trading; hands-on trading or strategy development experience is a strong plus
• Bonus: Experience with systems programming or performance-critical components using C and/or Java
• Bonus: Fluency or professional working proficiency in Russian or Ukrainian
