Mern Stack Develope

About the Role

Qiro is building the infrastructure powering the next generation of underwriting, credit analytics, and tokenized private credit markets.

As a Senior Full Stack Developer, you’ll design, build, and scale systems that bridge complex financial data, decision logic, and investor interfaces. You’ll work across the stack — from backend APIs and data systems to high-performance frontends for credit operations and analytics.

You’ll join a small, high-ownership founding team where every engineer contributes directly to product direction, architecture, and delivery. This is a hands-on, in-office role for builders who thrive in fast-paced startup environments and want to shape how institutional credit infrastructure is built from the ground up.

What You’ll Do

• Lead design and development of scalable backend systems and APIs using Python / TypeScript for underwriting, repayment, and investor workflows
• Build data-rich, interactive interfaces with React, Next.js, and React Query, powering analytics and workflow automation
• Implement form-driven, validation-heavy systems using Zod and Formik for onboarding, KYC, and investor flows
• Architect API-first frontends that integrate seamlessly with credit models, smart contracts, and data pipelines
• Write clean, maintainable, and well-tested code, and set technical standards for the team
• Collaborate with product, design, and data teams to translate complex financial logic into intuitive user experiences
• Own features end-to-end — from planning and architecture to deployment and monitoring
• Mentor and guide junior developers as we expand the engineering team

Who You Are

• 5+ years of professional full-stack experience, with 2+ years in senior or lead roles
• Strong proficiency in Python, TypeScript, and React, with experience in both backend and frontend architecture
• Skilled in RESTful API design, state management, and component-driven UI development
• Hands-on experience building data-driven or fintech products
• Familiar with validation, CI/CD, testing, and monitoring best practices
• Excellent communicator with a strong product sense and ownership mindset

Bonus Points

• Experience with AWS (Lambda, API Gateway, DynamoDB, RDS) and serverless architectures
• Familiarity with FastAPI, Pydantic, PostgreSQL, or similar frameworks
• Exposure to underwriting, lending, or credit analytics systems
• Prior experience in early-stage startups or 0→1 product environments

Why Join Qiro

• Be part of the founding engineering team shaping the future of credit infrastructure
• Work directly with founders, designers, and data scientists to ship impactful products
• Work from office only — collaboration, iteration, and speed are core to how we build
• Flat hierarchy and high autonomy — your work directly impacts direction and outcomes
• Competitive salary and meaningful equity
• Location: Bangalore

Our Culture

We believe in first-principles thinking, craftsmanship, and fast execution.

Everyone at Qiro is part of the core — we design for transparency, build for scale, and execute with ownership.

If you’re a builder who thrives in hands-on, high-ownership environments, and loves turning financial logic into elegant systems — we’d love to meet you.
