Manager, HR and Office Management
This is a pivotal role at the heart of ISEAL, bringing together strategic and operational HR leadership and effective office management to create an inclusive, well-supported workplace. The Manager, HR and Office Management will translate our new organisational strategy into forward-looking people practices, while ensuring that colleagues are supported by the policies, systems, resources and working environment they need to thrive.
Working closely with directors, the leadership team, line managers and two HR Coordinators, the postholder will shape the employee experience across the full journey—from recruitment and induction to development, progression and exit. The role will also oversee workplace services, internal communications, budgets and legal compliance across multiple jurisdictions (UK, Netherlands, Sweden, Switzerland, Belgium, and Canada), helping a hybrid and remote workforce stay connected, informed and confident. As an additional resource, an experienced HR consultant delivers recruitment campaigns and other special projects.

Above all, you will be collaborative, resilient and motivated by ISEAL’s mission to accelerate positive change for people and the planet.

- Cultivate a workplace where wellbeing is embedded in everyday practice and open, constructive dialogue flows well between employees, line managers and across the organisation
- Foster and continually enhance an inclusive employee experience across the full journey—from recruitment and induction to performance, progression, learning and development, and exit
- Navigate emerging employee matters with care, sound judgement and consistency, equipping line managers to confidently address both routine and complex HR situations
- Serve as a trusted strategic adviser to directors and the leadership team, bringing forward progressive HR practices that strengthen organisational effectiveness and employee engagement
- Coordinate support of a dedicated external HR consultant for recruitment and special projects
