Together with the development team, Product Owners and UX/UI designers, you drive the further development of our SaaS solutions (especially integrations and APIs).
You design, test, maintain and continuously improve the software, both independently and as part of your team.
You advise product management on technical matters and discuss functional and technical requirements and their implementation with them and the business units.
In the DevOps area, you increasingly take co-responsibility for architecture, coding and testing.
Through pair programming, code reviews and prototyping you not only develop our products but also grow professionally.
You regularly exchange ideas in “DevComs” or our Architecture Board with our agile, interdisciplinary teams.
You look beyond your own domain, implement your ideas during monthly GreenDays and have the opportunity to contribute those ideas to product development.
