Our mission is to modernize business financing and strengthen the European economy, one platform at a time.
The role
We are hiring a Senior Backend Software Engineer to join our product team on a full-time, hybrid basis. You will help design and scale the server-side systems that power our fintech solutions, working alongside frontend engineers, project managers, and fellow backend developers.
Core responsibilities

- Collaborate with frontend developers to ensure seamless integration between server and client layers while participating in technical solution design.
- Guarantee compliance with financial data security and privacy standards and maintain clear technical documentation for the team.

- Several years of proven experience developing back-end applications with C# and .NET.
- Hands-on experience integrating RESTful web services and applying modern web-development best practices.
- Strong written and verbal communication skills in English and the ability to work effectively within a cross-functional team.
- Prior exposure to the fintech sector is viewed as an advantage but is not required.

We offer equity compensation so you can share in the company’s growth. Additional benefits include hybrid work arrangements, medical insurance, and a dedicated mental-wellness budget. You will also have access to flexible retribution benefits through the Cobee mobile app, annual company gatherings, and bi-weekly team events that strengthen our international community.
