Location: Gurugram
Time zone overlap: Australia / Asia preferred

About the Role

We’re an Australian-based fintech startup building a data-driven finance platform focused on intelligent applications, lender eligibility, and automation.

The frontend is largely established. We’re now looking for a backend-focused engineer to take ownership of our data models, APIs, and platform logic as we scale.

You’ll work directly with the founder on architecture decisions and play a key role in shaping a system designed for long-term growth, AI integration, and complex financial workflows.

Key Responsibilities

· Design and maintain MongoDB schemas for applications, guarantors, assets, lender products, and eligibility logic

· Build clean, scalable Node.js APIs (Express or similar)

· Implement autosave logic, partial form persistence, and validation layers

· Ensure audit-safe data handling and consistency

· Optimise query performance, indexing, and data normalization

· Collaborate with frontend developers to define clear API contracts

· Prepare the backend for AI-assisted form parsing and lender ingestion pipelines

· Write clean, well-documented, production-ready code

About You

· 3+ years professional experience with Node.js and MongoDB

· Strong experience designing real-world data models (not just CRUD APIs)

· Comfortable owning backend architecture decisions

· Experience building APIs consumed by complex frontend applications

· Familiarity with Mongoose or similar ODMs

· Understanding of authentication, authorization, and API versioning

· Startup mindset — pragmatic, outcome-driven, and able to work autonomously

· Clear English communication and documentation skills

Nice to Have

· Experience in fintech, lending, or financial services platforms

· Exposure to rules engines or eligibility / decision systems

· Previous AI or machine learning integration experience

Why Join

· Early hire with genuine architectural influence

· Direct collaboration with the founder on product and technical direction

· Clear path to long-term role or technical leadership position

· Competitive pay with flexible structure
