What you will do

We are looking for a Junior Backend Engineer who is passionate about clean, readable and scalable code.

You will be responsible for building high-performance APIs that transform terabytes of data into valuable insights that help over 100.000 hotels worldwide make well-informed decisions. Your team works in close collaboration with our product team and a highly talented group of software engineers, DevOps engineers and project managers to drive initiatives forward.

Where you will have impact

• Work on new feature developments for our existing products as well as creating new products from scratch.
• Architect, code and maintain existing & new Python/Go (micro-)services.
• Deploy and monitor services in a reproducible and scalable way.
• Develop a high affinity with our various, often complex, datasets by crunching large amounts of data on the fly in API implementations and data processing jobs.
• Experiment with, think about and take ownership of a piece of our codebase/infrastructure and find ways to improve it, both in terms of performance/efficiency and structure/best practices.
• Ensure high quality deliverables through extensive testing as part of your development process.
• Be part of the product scrum-teams, creating high performing and efficient APIs related to new feature developments.
• You will be at the forefront of our AI evolution, helping to embed intelligence into our platform. You’ll not only build AI features for our customers but also champion an AI-first development culture within the engineering team.

Who you are

• Bachelor or Master degree in a software engineering field.
• You set a high bar for yourself, and expect others to do the same. You’ll find we have an exceptionally talented team and are constantly looking for the best people to join.
• You are passionate about what you do. What unites us is our passion to do great work that our users benefit from.
• You are creative, entrepreneurial and open to innovation. We strongly believe that everything can be improved. We expect you to think and learn about new technologies, and take initiative to try and suggest new things.
• You are a critical thinker who understands that perfect is the enemy of the good. We don’t over-engineer, but we do whatever it takes to achieve our goals.
• You work well in a team, but don’t mind getting your hands dirty. You’ll quickly learn that we have a very open culture where everyone can be reached out to for help, ideas, feedback and much more. But everyone takes responsibility for their own work.
• You are a forward-thinking builder who views AI as a core component of modern architecture. You have a proven interest (or experience) in working with LLMs, agentic workflows, or AI-assisted coding tools to ship higher-quality code, faster.
• Fluent in English.

We welcome

• Experience writing Python and/or Golang.
• Experience with any cloud platform.
• Fluency in SQL.
• Good software engineering practices, e.g. use of version control.
