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
