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

- 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.
