Advisory & Business Collaboration

• Deliver accurate, compassionate, and professional HR guidance to managers and employees as a first point of contact.
• Partner with People Partners and cross‑functional teams to provide timely administrative support.
• Support core cyclical activities, including performance appraisals, compensation planning, and HR audits.
• Contribute actively to team meetings, sharing knowledge and collaborating across the wider People team.
• Lead on assigned projects with support from the People Operations Partner.

• Professional proficiency in English; additional EMEA language proficiency is welcome.
• Proficiency with Gen AI tools relevant to HR and administrative work, used to improve output quality and efficiency.
• Experience building personal AI workflows to streamline how you work.
• An agentic approach — you break down complex tasks and find efficient solutions independently.
• Ability to critically evaluate AI outputs and apply human judgement before acting on them.
