Job description

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

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;

What We're Looking For

Must Have

• 5+ years of professional software engineering experience

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

REST APIs

• Experience with relational databases (PostgreSQL preferred) — schema design, query

• 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

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 Client Company

• 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
