- Collaboration: Work closely with cross-functional teams, including designers, researchers and business stakeholders, to align technical solutions with business objectives.
- Code quality: Write clean, efficient and maintainable code, participate in code reviews and contribute to continuous improvement initiatives.
- Problem Solving: Find creative solutions to technical challenges and continuously explore new tools and methods to improve the platform.
- Experience with Python (for Django) and JavaScript (for React).
- Experience building and maintaining RESTful APIs and integrating front-end and backend systems.
- Good understanding of relational databases, especially PostgreSQL.

- Previous experience in a startup environment or scaling digital products.
- Competitive salary, with growing bonuses depending on the success of the company.
- An opportunity to shape the future of geoFluxus and directly impact sustainability.

- A 36-hour work week, where you have a Friday off every other week - without it affecting your salary!
- A hybrid work environment, with office hours in Rotterdam from Wednesday to Friday and flexible options for working from home.
- Quarterly offsite in the Netherlands or abroad, where we plan, brainstorm and get to know each other better!
Language and office
Excellent command of the English language is required for effective communication within our international team. Our team combines working from home and working from our office in Rotterdam next to central station. Ideally we will see you every week in our Rotterdam office, but we are also open to candidates from Europe as long as they work in the same time zone. Unfortunately we cannot offer visas or sponsorship.
