Join Innolume Working Student HR Operations & Digitalization (f/m/d) Help us turn Personio into a modern, well-engineered backbone for HR Location: Dortmund, Germany (on-site preferred; remote by arrangement) Employment Type: Working Student | Up to 20 hours/week, 16 euros per hour | Starting immediately At Innolume, we develop innovative optoelectronic semiconductor technologies for next-generation communication, sensing and photonic applications. Just as we push our technology forward, we want our HR processes to be modern, efficient and well-engineered. To strengthen our HR team, we are looking for a Working Student HR Operations & Digitalization (f/m/d) who wants to do more than support day-to-day HR tasks – someone who wants to help shape, digitalize and improve how we work.
This is not a role for simple support tasks: from day one, it comes with real responsibility and genuine room to make an impact. Our HR department is currently migrating to Personio, and we're using this step not just to move existing processes into a new system, but to question, simplify and automate them. This is exactly where you come in: you will help us develop Personio as our central HR platform and take on, step by step, responsibility for the system and the processes behind it.
Your workplace is preferably with us on-site in Dortmund; remote work is possible by arrangement. We coordinate your working days flexibly around your class schedule – we won't dictate fixed weekdays – and during semester breaks, a higher weekly hour count is possible on request. Your responsibilities Personio & Product Ownership: You actively work on the introduction and further development of Personio.
You get to know our requirements, translate them into sensible system solutions, and increasingly become a central point of contact for our HR system. Digitalization & Automation: Onboarding, offboarding, absences, documents, approvals and recurring administrative tasks: you analyze existing workflows and help us make them more digital, leaner and more automated. Optimize HR processes: “We've always done it this way” is not a convincing argument for you.
Together we look at our workflows and consider what can be simplified, what can be automated, and where we can create a better employee experience. Personnel administration: You get to know the operational foundation of professional HR work, support us with administrative HR processes, and help ensure that data, documents and workflows run reliably. Take on your own projects: We're explicitly not looking for someone who just works through a task list.
Once you're settled in, you should take ownership of your own topics, develop solutions and bring in your ideas. Your profile Required Enrolled student, for example, in business administration, HR management, business psychology, business informatics, or a comparable field – how you approach topics matters far more to us than your specific field of study Interest in the intersection of HR, processes and technology Quick grasp of new software and digital tools A structured way of working and enjoyment in getting to the bottom of complex workflows Enjoyment in questioning processes and developing better solutions Reliability and care when handling sensitive personnel data Ability to work independently and enjoyment of teamwork Fluent German and English, written and spoken – English is our corporate language Nice to have Experience with Personio is a plus – but explicitly not a must. What matters far more to us is your willingness to get deeply familiar with the system.
What we offer Up to 20 hours per week, flexibly arranged – no fixed weekdays, and more hours possible during semester breaks on request Start immediately A modern workplace in Dortmund Remote work by arrangement, though we prefer working together on-site Real responsibility and your own room to shape things Very good chance of being kept on with us after you finish your studies Deep insight into modern HR operations Hands-on experience with Personio, process design and automation Short decision-making paths and the chance to actually implement your own ideas A role in which you can grow professionally and build valuable experience for your career Ready to make an impact? Join Innolume and help us turn HR digitalization into a smooth, modern experience for our whole organization. We look forward to receiving your application .
