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
