The ideal candidate will have hands-on experience building low-latency, high-throughput microservices using Node.js and Nest JS.


The Role

This is a senior-level position that requires a deep understanding of backend development, API-driven architectures, and cloud-native practices.

  • Build real-time APIs and services over REST, Web Sockets, and g RPC to support live trading, portfolio updates, and event-driven alerts.
  • Optimize systems for sub-100ms response times where required, enabling trading-grade performance.
  • Define clear API contracts and generate Swagger/Open API documentation.
  • Ensure seamless integration with mobile frontend, AI/ML services, and data pipelines.
  • Implement authentication and authorization (JWT, OAuth2).
  • Integrate secure practices for handling financial and personal data (KYC, 2 FA, PCI/DSS awareness).
  • Establish logging, monitoring, and audit trails for regulatory alignment.

Requirements

To succeed in this role, you will need:

  • 10+ years of backend development experience, with strong proficiency in Node.js and Nest JS.
  • 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, Web Sockets, g RPC, and event-driven architectures.
  • Experience with Swagger/Open API, API lifecycle management, and contract-first development.
  • Strong understanding of cloud-native practices, containerization, and CI/CD pipelines (GitHub Actions).
  • Familiarity with financial/trading systems is a significant plus.
  • Deep knowledge of security practices (JWT, OAuth2, KYC workflows, PCI compliance awareness).
  • A DIY builder and founder mindset: resourceful, entrepreneurial, and willing to operate in ambiguity.
  • Willingness to work in an equity-only, pre-funding startup environment.
