Founding Backend Developer

Founding Backend Developer (Node/NestJS & Microservices)

Equity Only | Pre-Seed Stage Startup | India Only

About Us

We are building an industry-leading FinTech 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. 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 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.

What You'll Do

- 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.
- Collaboration & Startup DNA
- Work 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 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.
- Collaborate with a small, elite founding team across AI, Data, and Frontend.
- Equity-based compensation at pre-angel stage: high risk, high reward, massive ownership potential.
- Shape the core product and technology stack at the ground floor.
