Lead People Operations & Strategic HR Business Partner (m​/f​/d

About us

ATOSS Software SE is one of Germany's most successful tech growth stories. As the market leader in Workforce Management Software, we help companies work more intelligently, creatively, and humanely optimizing the balance between profitability and people.

We're a rare company: according to Handelsblatt (10/24), just 309 public companies worldwide achieved over 20% return on sales for ten consecutive years. Only one based in Germany: ATOSS Software SE.

With 20 years of record breaking growth, over €2 billion market cap, and listings in SDAX and TecDAX, we're scaling globally and we're growing.

If you're ready to drive impact in a high-performing B2B SaaS environment, this is your chance to elevate your career.

At ATOSS, we hire for both character and skill, seeking individuals who embody resilience, a pioneering spirit, and the passion to grow.

We value those who:
Think like entrepreneurs - taking ownership, pushing boundaries, and driving impact. Challenge the status quo - bringing fresh ideas and bold execution to the table. Thrive in change - seeing growth as a lifelong journey, both professionally and personally.

We don't just equip you for work - we prepare you for life.

We are looking for a strategic and hands‑on Senior HR Business Partner & Lead People Operations to serve as a trusted people advisor to our Finance, IT, Legal, and Digital Transformation functions. This is a dual‑impact role: you will drive forward‑looking HR strategy at the business unit level while simultaneously owning operational HR excellence through a small HR Admin team. An ideal candidate will bring deep expertise in German labour law - a qualification as a German lawyer would be a distinct advantage - combined with a proven track record in fast‑paced, technology‑driven environments.
