Python Developer
Why This Role
You'll build systems that move real money and digital assets โ exchanges, payment rails, crypto processing, and OTC desks โ where every decision touches security, latency, and correctness. The
problems are real: real adversaries, real settlement guarantees, real users who can't afford downtime. If you want ownership over production fintech infrastructure rather than another CRUD app, this is that.
You'll join a small team shipping to production frequently, owning features end-to-end across our backend services, customer-facing products, and internal back-office tools.
Tech Stack
- Backend: Python 3.12, FastAPI, SQLAlchemy + Alembic, Gunicorn/Uvicorn
- Frontend: React 18 + TypeScript, Vite, Tailwind + shadcn/ui, React Query
- Back-office: React 18 + TypeScript, Vite, Tailwind + shadcn/ui
Databases: PostgreSQL 17 + MongoDB
What You'll Do
- Own full-stack features from spec through deployment, monitoring, and iteration
- Build and maintain FastAPI services handling payments, exchange, and crypto-processing flows
- Develop responsive interfaces for both customer-facing products and internal back-office tools
- Model and optimize data across PostgreSQL and MongoDB; manage migrations with Alembic
- Integrate third-party payment, banking, and crypto APIs
- Bake security and compliance into everything โ you'll be trusted with money-handling code, often without a dedicated QA safety net
Must Have
- 5+ years full-stack experience, with at least 3 building production backend services
- Strong command of Python / FastAPI and React + TypeScript
- Solid experience with PostgreSQL (relational modeling, query optimization)
- Advanced, daily use of AI tools in your workflow โ you use assistants like Claude, Copilot, or
- Cursor to scaffold, refactor, and review code, and you can judge when to trust their output and when
to discard it
- Genuine independence โ you take ownership, make sound calls, and drive work forward with minimal oversight (essential on a remote, fast-moving team)
Bonus
- Experience with MongoDB and the wider frontend stack (Vite, shadcn/ui, React Query)
- Fintech background โ payments, banking, PSP, or exchanges
- Crypto / digital assets โ exchanges, processing, custody, or OTC (a strong extra plus)
