We’re building financial data systems that power real business decisions — and we need someone who knows how to make Django, PostgreSQL, Celery, and APIs play nicely at scale.


You know what clean, reliable backend systems look like — because you’ve built them. You’ve handled authentication quirks, rate limits, and webhooks; you build code that’s maintainable, performant, and correct.


If you’re curious about financial data, transactions, and KPIs, and enjoy turning numbers into insight, this role is for you. (Experience with banking or accounting APIs is a big plus.)



What You’ll Do

  • Build and maintain Django-based systems using Celery for async and scheduled tasks
  • Integrate and manage data from multiple APIs (banking, accounting, analytics, etc.)
  • Design and optimize internal APIs
  • Improve reliability, scalability, and performance
  • Collaborate closely with product and frontend engineers


Your Profile

You’re an experienced backend engineer who is strong in all core areas of modern Python development:

  • Python, Django, Django REST Framework
  • Celery and asynchronous / distributed task handling
  • PostgreSQL and robust data modeling
  • Docker and containerized deployment workflows
  • Unit testing (pytest or equivalent) and maintainable test structures
  • Git, CI/CD, and reliable deployment automation
  • API integrations (REST, OAuth, webhooks)
  • Caching strategies & background job handling (preferred Redis experience)
  • Solid understanding of security, permissions, and performance optimization


You’ve already built or scaled production-grade systems and can take ownership from architecture to deployment.


Experience with fintech or data integration systems is an advantage.


How We Work

We’re a small, remote-first team that values ownership over micromanagement.


You’ll have freedom in how you work — what matters is your impact.

Our daily language is English.


About finban

We’re building a platform that helps businesses understand and manage their financial performance in real time by connecting and analyzing data from banking, accounting, and analytics systems.


If you’ve built or scaled production Django systems before and love clean architecture — we’d love to see your work.

About

finban gives small and mid-sized companies a clear view of their financial future. The platform connects bank accounts (PSD2), accounting systems such as DATEV, Lexware Office and sevdesk, payment providers like Stripe and PayPal, CRM systems and spreadsheets — and consolidates them into a single, always-current liquidity plan.


What sets finban apart is how it handles data. Instead of forcing one source of truth, actuals from the bank, open receivables and payables from accounting, and forward-looking budget assumptions coexist side by side. As real payments come in, they replace the plan automatically. The result is a forecast that stays accurate without manual maintenance.


Built in Germany, finban today serves primarily the DACH market — with an integration and banking layer designed to extend across Europe and beyond. It's made for companies of up to around 100 employees: teams that need serious financial visibility but don't have a dedicated treasury department to produce it.
