The Role

We are seeking a Founding Backend Developer with in-depth expertise in Node.js, NestJS, and microservices architecture to design and deliver the high-performance backend powering our trading platform. This is a hands-on, builder 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, pre-funding environment .

  • API-First Development
  • Define clear API contracts and generate Swagger / OpenAPI documentation .
  • Ensure seamless integration with mobile frontend , AI / ML services , and data pipelines .
  • Security & Compliance
  • Implement authentication and authorization (JWT, OAuth2).
  • Integrate secure practices for handling financial and personal data (KYC, 2FA, PCI / DSS awareness).
  • Establish logging, monitoring, and audit trails for regulatory alignment.
  • Scalability & Reliability
  • Design systems that can scale horizontally under heavy load.
  • Ensure fault tolerance, failover mechanisms, and efficient resource utilization.
  • Build observability into services with metrics, tracing, and alerts.
  • Collaboration & Startup DNA
  • Work closely with the Frontend , AI , and Data Engineering teams to build seamless end-to-end flows.
  • Take complete ownership of backend development : from initial design to deployment and monitoring.
  • Contribute to technical vision and make early architectural choices that define the company’s long-term success.

What We’re Looking For

  • 10+ years of backend 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.
  • 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.

    • Why Join Us

  • Be the founding architect of backend systems that power a next-gen FinTech platform.
  • Build Robinhood-class infrastructure with trading-grade performance and reliability .
