Full Stack AI Engineer

Location: Hyderabad, India (On-site)

Type: Full-time

Reports to: Founder / CTO About the Company

We are hiring for a London-based FinTech startup that is building agentic AI solutions for financial services operations. The company is transforming how financial institutions manage data operations by automating the entire lifecycle from data ingestion and transformation to intelligent matching, break detection, and resolution eliminating manual spreadsheet-driven workflows.

As one of the early engineering hires, you'll work closely with the technical founder, contribute to a production-grade AI-powered SaaS platform, and have the opportunity to own features end-to-end while helping shape the product and engineering culture from the ground up. The Role

You will work across the full stack of a production SaaS platform — backend APIs, frontend UI,

data pipelines, and AI-powered features — to build, extend, and ship product capabilities to financial institution clients. This is a high-ownership role where you will design and implement features end-to-end, not just pick up tickets. What You'll Work On

Backend Development — Build and extend Django REST APIs, design data models,

and implement business logic for reconciliation workflows (ETL pipelines, matching engines, break management).

Frontend Development — Develop rich, responsive UI features using React/Next.js with TypeScript — data tables, configuration editors, dashboards, and real-time status views

AI/LLM Integration — Build and improve AI-powered features including intelligent document extraction, AI-assisted matching rules,



conversational configuration agents,

and automated break analysis

Data Processing — Work with high-performance data processing pipelines using

Polars/Pandas for financial data transformation/reconciliation at scale.

Asynchronous Workflows — Design and implement distributed task workflows using

Celery for ETL orchestration, matching execution, and report generation

Testing & Quality — Write comprehensive tests (pytest, Vitest, Playwright) and maintain high code quality in a fast-moving codebase

Production Support — Debug and resolve production issues alongside the founder;

understand the full request lifecycle from browser to database What We're Looking For

Must Have

3+ years of professional software engineering experience

Strong proficiency in Python (Django AND FastAPI), with experience building production REST APIs

Solid JavaScript/TypeScript skills with experience in React (Next.js preferred)

Experience with relational databases (PostgreSQL preferred) — schema design, query optimisation, migrations.

Familiarity with Git workflows, code review, and CI/CD practices.

Ability to learn new domains quickly — you don't need FinTech experience,



but you need the curiosity to understand reconciliation workflows deeply.

Solid problem-solving skills and comfort working independently in a startup environment. Great to Have

Experience with LLM/AI integration in production applications (prompt engineering, API orchestration, LangChain/LangGraph)

Experience with data processing at scale (Polars, Pandas, Apache Arrow)

Knowledge of asynchronous task queues (Celery, Redis)

Familiarity with AWS services (ECS, S3, RDS, CloudWatch)

Experience with Docker and containerised development/deployment

Exposure to FinTech, capital markets, or financial operations (reconciliation,

settlements, NAV, cash management)

Experience with document parsing/extraction (PDF, Excel, SWIFT messages)

Familiarity with component libraries (Radix UI, shadcn/ui, TailwindCSS) Why Join our team

Founding team member — Shape the engineering culture and technical direction from day one

High ownership — You will own entire features end-to-end, from database schema to pixel-perfect UI. Your code ships to production the same week

Work with cutting-edge AI — Production LLM workloads, agentic AI, and intelligent document extraction — not just buzzwords on a slide deck

Direct founder access — Work alongside the technical founder who built the platform;

no layers of middle management

Real impact — Financial institutions are running their daily operations on what you build. Your work matters on day one

Growth trajectory — Early hires at funded startups define their own career paths as the company scales
