Backend Developer Position

We are building an industry-leading mobile app 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.

The Role

You will design and deliver the high-performance backend powering our trading platform using Node.js, NestJS, and microservices architecture. This is a hands-on, builder role where 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.

  • Backend Architecture & Development: Design and implement low-latency, high-throughput microservices using Node.js and NestJS.
  • Build real-time APIs and services over REST, WebSockets, and gRPC to support live trading, portfolio updates, and event-driven alerts.
  • Optimize systems for sub-100ms response times where required, enabling trading-grade performance.
  • 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.
  • Collaborate closely with the Frontend, AI, and Data Engineering teams to build seamless end-to-end flows.
  • Take full ownership of backend development: from initial design to deployment and monitoring.
  • Contribute to technical vision and make early architectural choices that define long-term success.

Required Skills and Qualifications

  • 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 highly beneficial.
  • 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.
  • Ability to work in an equity-only, pre-funding startup environment.
