The ideal candidate will have in-depth knowledge of microservices architecture, experience with REST, WebSockets, and gRPC, as well as strong proficiency in authentication and authorization protocols (JWT, OAuth2).

You will work closely with our technical team to create fault-tolerant, scalable systems that can handle heavy loads and ensure seamless integration with mobile frontend, AI/ML services, and data pipelines.

  • Build fault-tolerant, scalable systems that can handle heavy loads and ensure seamless integration with mobile frontend, AI/ML services, and data pipelines.
  • Implement authentication and authorization (JWT, OAuth2), secure practices for handling financial and personal data (KYC, 2FA, PCI/DSS awareness), and establish logging, monitoring, and audit trails for regulatory alignment.

Requirements:

  • 10+ years of back-end development experience, with strong proficiency in Node.js and NestJS.
  • Proven expertise in designing and implementing microservices and API-driven architectures.
  • Hands-on experience building low-latency, high-performance systems (sub-100ms response targets).
  • Solid knowledge of REST, WebSockets, gRPC, and event-driven architectures.
  • Experience with Swagger/OpenAPI, API lifecycle management, and contract-first development.

About This Role:

This is a unique opportunity to shape the core product and technology stack at the ground floor. You will work closely with our founding team to create Robinhood-class infrastructure with trading-grade performance and reliability.

What We Offer:

A dynamic and supportive work environment, opportunities for growth and professional development, and a chance to make a meaningful impact in the FinTech industry.
