Position Summary

You will provide high-level administrative and operational support that keeps the Onyx team running smoothly, day to day and across the globe.

This is a role for someone with excellent organisational skills, sharp attention to detail, genuine discretion, and the confidence to juggle competing priorities in a fast-paced environment. We value clear communicators who lead with empathy, act with integrity, and focus on impact for patients and science. This role offers growth, visible impact and a chance to help unite science, technology and talent to get ahead of disease together.

• Onboarding and people support — co-ordinate the onboarding of new starters and guide them through their first weeks; liaise with Line Managers, HR, IT and Facilities to ensure a smooth joining experience, from GSK system access and hardware to office passes and meeting invitations; keep distribution lists and organisation charts accurate and up to date.
• Office administration — provide general administrative support across all Onyx locations, including guest access, and maintain the Onyx ‘Trip Wiki’ so colleagues have practical, current advice for every site.
• Travel and expenses — arrange domestic and international travel via Concur, including flights, accommodation, visas and itineraries; manage expense reports and reconciliation, ensuring accuracy and full policy compliance.
• Finance and vendor management — raise purchase orders in line with company procedures using Ariba; track invoice payments and follow up on outstanding balances using Fiori; partner with the Onyx Finance partner, Procurement and external suppliers.

• Proven experience as a Personal Assistant, Executive Assistant, or in a similar role.
• Demonstrated experience of complex diary management and booking domestic and international travel.
