Job Description

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.
• Familiarity with financial/trading systems is a major 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.
