Backend Developer C# (.NET)

At Chift, we’re building the future of financial integrations for SaaS.

Founded in 2022, we’ve already grown from 4 to 30 people and work with leading SaaS companies like Revolut, Qonto, Pennylane, and many more.

Our goal? Become the European leader in financial software integrations by 2027 🚀

We build Unified APIs that help B2B software companies connect instantly to accounting, invoicing, e-commerce, and POS tools. Saving them months of development and unlocking new growth.

We’re a fast-growing startup with big ambitions and a humble, hungry team. Now is the perfect time to join us.

As a Backend Developer C# (.NET) at Chift, you’ll be at the heart of what we build. You’ll work closely with one of our co-founders and take ownership of new connectors, API features, and improvements to our core platform.

Your work will directly impact how dozens of SaaS companies integrate with financial tools and scale their own products.

This is a great opportunity for someone who wants to build real things, fast, and grow in a high-trust, high-ownership environment.

You’ll play a key role in building and maintaining our integrations and platform:

• Develop backend services and connectors in C# (.NET)
• Build new endpoints for our Unified APIs
• Integrate with external software (accounting, invoicing, e-commerce, POS...)
• Design efficient data models
• Contribute to a scalable and robust API architecture
• Document your work and collaborate with the team
• Analyze business logic: we don’t just code features, we understand why they matter
• You’ll also have the opportunity to grow into a tech lead role if that’s something you’re aiming for

• Solid experience in C# / .NET (Web API, Entity Framework...)
• 3+ years of experience in backend development
• Good understanding of relational databases (SQL Server, PostgreSQL...)
• Comfortable with REST APIs, authentication flows (OAuth), and backend performance
• Curious and business-minded — you enjoy learning how things work behind the scenes
• Eager to build things from scratch, iterate fast, and own your work
• Entrepreneurial spirit — you thrive in a startup environment where everything moves fast
• Languages: French fluency required, English is a plus. Spanish or Dutch? Even better!
