Job details:
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.
- Strong 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
