Job description

Hands-on full-stack lead owning design, development and go-live of client implementations on our AI-driven platform.

Experience

8-10 years

About the Role

We are seeking a highly skilled and hands-on full-stack development lead to own the design, development and delivery of client implementations on our AI-driven platform. Our software goes live inside banks, NBFCs and financial institutions, and every go-live is a project with a client on the other side of it.

You will work closely with the architect, AI engineers, infrastructure teams and product to deliver intelligent, secure and highly available solutions. As a technical leader you will drive engineering excellence, mentor junior developers, and champion AI-assisted development practices while remaining hands-on in the code.

Key Responsibilities

Lead technical design and delivery

Architecture and implementation of client-facing implementations, end to end from design through deployment and production handover.

Build scalable services

Microservices and distributed systems in Python - or Java or Go where it earns its place.

Own the full stack

Backend services plus the frontend the client actually uses - React / Next.js, TypeScript, responsive delivery.

Mentor the team

Code reviews, pair programming, design discussions and raising engineering practice for three to six engineers.

Integrate AI into delivery

Work with the AI/ML function to embed LLMs, agents and AI-powered services into client applications.

Design the interfaces

Scalable REST APIs, event-driven systems and asynchronous messaging against bank and NBFC systems.

Own scope and go-live

Estimate, commit, raise risk early; cutover planning, hypercare and a real handover to production support.

Champion AI-assisted development

Use and set the standard for Claude Code, Copilot and Cursor in day-to-day engineering.

Feed the product

Decide what a client asked for that belongs in the product, and route it there instead of forking.

What You Bring

• 8-10 years building and delivering software, including 2+ years leading a squad through production go-live.
• Strong proficiency in Python; Java or Go additionally is welcome. FastAPI and async service design in production.
• Microservices, REST APIs and distributed systems you have designed, not just worked in.
• Hands-on full-stack capability - React / Next.js and TypeScript; Node.js and the MERN stack is relevant experience.
• Strong PostgreSQL - schema design, query tuning, migrations; plus caching (Redis) and messaging.
• Working knowledge of cloud platforms (AWS preferred), Docker, Kubernetes and CI/CD.
• Client-facing ownership: scope, estimate, escalation and the difficult conversation about a date.
• Integration experience against banking or financial systems, including sandbox and approval realities.
• Familiarity with AI-assisted development tools (Claude Code, GitHub Copilot, Cursor) as part of how you work.

What Would Be Great to Have

• Exposure to LLMs, AI agents, RAG or MCP, or prior AI-platform development.
• Infrastructure as code - Terraform or Ansible - and a working understanding of networking.
• Lending, payments, collections or onboarding domain depth.
• Pre-sales and solution-estimation support.
• Experience of the forward-deployed engineer model.
