Do we have your attention?
At Holzkern, we believe that great products need a great operational engine behind them. We are one of the most successful D2C brands in DACH — selling watches, jewelry and accessories made from natural materials to over 2.500.000 customers worldwide. We have more than 170 people, and we are growing.
For that to work, every internal system needs to run well.That is where you come in. We’re looking for a junior talent drawn to HR for the systems , not just the conversations: data, reliable workflows, and processes that you’ll improve month after month. We’re a scale-up, not a corporation. Our systems aren’t perfect, and fixing them is part of the job. You learn by figuring things out and owning the result, with context and clear feedback from the team. If that sounds exhausting, this isn’t your role.
If it sounds like the fastest way to grow, let’s talk.
Your areas of responsibility
You will own the operational backbone of our HR function: the systems, the data, the processes, and the documentation that keeps everything running correctly. This is not a coaching or culture role. It is an operations role that happens to live inside HR.
HR Systems & Personio Administration Maintain employee master data: working time, absences, vacations, sick leave, role and contract information

Process Improvement & Workflow Optimization
This is a core ownership area. Every recurring manual process in HR is in scope — preboarding checklists, document workflows, recurring requests, data correction routines, and more. Identify recurring manual tasks and systematically reduce them
Document how current workflows run before changing them; measure impact after
Build templates, checklists, and automations so the same work is never started from scratch twice
Suggest simpler or automated alternatives for repetitive admin work
