Full job description

Salary: £47,040 - £58,800 p.a

Closing date: 15 July 2026

Contract type: Permanent

Interview dates: 1st stage (w/c 20 July 2026), 2nd stage (w/c 27 July)

Wellcome is a global charitable foundation. We improve health for everyone by funding science, leading policy and advocacy campaigns, and building partnerships.

We plan to spend £16bn over the next ten years, funding new discoveries in life, health and wellbeing and taking on three global health challenges: mental health, infectious disease and climate and health.

We are looking for an Executive Assistant who will provide support to Maggy Chan, our Chief Operating Officer (COO).

Where in Wellcome will I be working?

You will help the COO to deliver the mission by ensuring her time is optimised and prioritised for the benefit of Wellcome.

What will I be doing?

This is an exciting opportunity for an experienced Executive Assistant to play a key role in supporting the COO and the broader Operations team in delivering on Wellcome’s inspiring mission. Your primary focus will be using your judgement to proactively anticipate challenges, adjusting schedules, managing stakeholders and working with internal teams and external stakeholders effectively to ensure delivery to deadlines. The role is essential to the smooth running of the COO’s office, being the central point of contact for the team and working closely with the Head of Executive Office, ensuring access to the COO as required.

As an Executive Assistant you will:

Provide comprehensive executive and departmental administrative support to the COO, proactively resolving operational issues and coordinating effectively with the CEO Office, Executive Director offices, and key teams across the organisation.
Manage the COO’s complex diary and scheduling, using sound judgement to coordinate meetings, resolve conflicts, and adapt calendars dynamically to changing priorities.
Prepare and coordinate high-quality agendas, briefing materials, presentations, and meeting documentation, ensuring the COO was effectively supported for internal and external engagements through timely collaboration with stakeholders across the organisation.
Coordinate internal, external, and department-wide meetings and events, managing agendas, documentation, and minutes while collaborating across teams to ensure effective planning and delivery of key organisational initiatives.
Manage complex domestic and international travel arrangements for the COO, producing detailed itineraries and coordinating tailored briefing packs to support effective engagement during business trips.
Ensure compliance with organisational policies and procedures, maintain departmental business continuity plans, and promote adherence to governance, expenses, hospitality, and compliance requirements.
Support departmental budget management by monitoring expenditure, reviewing financial reports, and processing expenses and invoices in line with organisational policies and procedures.
Manage departmental office operations and facilities, coordinating workspace moves, procurement of furniture and supplies, and liaising with facilities teams to maintain an efficient working environment.

Is this job for me?

You will enjoy this role if you thrive in a fast-paced environment, enjoy supporting senior leaders, and excel at managing complex priorities. You are highly organised, proactive, and skilled at coordinating meetings, travel, communications, and operations while building strong relationships across an organisation and ensuring everything runs smoothly.

Minimum Criteria:

Executive Assistant/Office Management experience, supporting stakeholders at a senior level.
Advanced IT Skills – excellent working knowledge of Microsoft Office software, expenses software (e.g. Oracle), CRM (e.g. Salesforce).
Manage calendars effectively while demonstrating strong written and verbal communication, organisation, planning, and the ability to prioritise multiple tasks.
Excellent time management, and project coordination skills to ensure efficient scheduling and delivery of work.

We are currently working 3 days per week (Tuesday, Wednesday and Thursday) from our Euston Road offices (as part of our hybrid Ways of Working) with the remaining 2 days working either remotely or in the office.

Diversity and Inclusion is at the heart of everything we do

Diversity and Inclusion is a priority at Wellcome. We are committed to cultivating a fair and inclusive environment, where everyone can be themselves and thrive. We are happy to discuss flexible working options for all roles. We work to ensure that our recruitment processes are as inclusive as possible to everyone.
