• Good knowledge of relational databases, SQL, and Entity Framework or a similar ORM
• Experience designing REST/HTTP APIs and implementing backend business logic for production systems
• Ability to write clean, maintainable, and testable code while making pragmatic technical and design decisions
• Ability to translate complex business requirements into reliable technical solutions
• Practical use of AI-assisted development tools and good written and verbal communication skills in English

What you’ll get in return

• Exciting project. We work with some of the most innovative companies that literally change the world. If space exploration excites you, then you will not feel bored with us.
• Hybrid working model: We value working in the office and at home, so we offer a hybrid working arrangement - 3 days a week from the office.
• Comprehensive healthcare including life insurance, and a Multisport Card.
• Impact. We give you an opportunity to work for an organization where you will have the ability to make an impact and ability to access and interact with the product owners, management team, and clients.
