We support stable performance, high engagement, and a strong employee experience.
 

As a Head of HR, you will:

Partnering with the HR team and the broader People Operations function, you will build a people system where strong teams consistently deliver business results.

• Strong business acumen and leadership skills — able to challenge leaders, navigate ambiguity, and make tough decisions that impact delivery.
• English — Upper Intermediate+.
• Alignment with the values of our team (SELECT).
