Behind the Scenes

We are crafting an industry-leading FinTech mobile application that brings hedge-fund-grade trading intelligence to everyday investors.

Think Robinhood, but powered by AI-driven insights, ultra-low-latency systems, and transparent user experiences. As part of our founding technical team, you will architect and implement the backend foundation that powers our entire platform — from trading services and portfolio management to real-time data streaming and user-facing APIs.

The Role

We are seeking a skilled developer with in-depth expertise in Node.js, NestJS, and microservices architecture to design and deliver high-performance backends powering our trading platform. This is a hands-on role: you will create systems that handle real-time financial data, low-latency execution pipelines, and mission-critical APIs that integrate with frontend apps, AI engines, and external brokerage APIs.

You will bring a DIY founder mindset, taking ownership of backend reliability, security, and scalability in an equity-only environment.

Key Responsibilities
  1. Backend Architecture & Development
  2. Design and implement low-latency, high-throughput microservices using Node.js and NestJS.
  3. Build real-time APIs and services over REST, WebSockets, and gRPC to support live trading, portfolio updates, and event-driven alerts.
  4. Optimize systems for sub-100ms response times where required, enabling trading-grade performance.
  5. API-First Development
  6. Define clear API contracts and generate Swagger/OpenAPI documentation.
  7. Ensure seamless integration with mobile frontend, AI/ML services, and data pipelines.
  8. Security & Compliance
  9. Implement authentication and authorization (JWT, OAuth2).
  10. Integrate secure practices for handling financial and personal data (KYC, 2FA, PCI/DSS awareness).
  11. Establish logging, monitoring, and audit trails for regulatory alignment.
  12. Scalability & Reliability
  13. Design systems that can scale horizontally under heavy load.
  14. Ensure fault tolerance, failover mechanisms, and efficient resource utilization.
  15. Build observability into services with metrics, tracing, and alerts.
  16. Collaboration & Technical Leadership
  17. Work closely with the Frontend, AI, and Data Engineering teams to build seamless end-to-end flows.
  18. Take full ownership of backend development: from initial design to deployment and monitoring.
