Job Description

Are you organised, proactive, and enjoy being a reliable support to a busy team?

Join NASS as our Administrative Assistant and provide essential administrative support that helps our team work towards better diagnosis and care for people living with axial SpA - an invisible, often misdiagnosed inflammatory condition affecting the spine.

WHAT MAKES THIS ROLE SPECIAL

This is an exciting time to join our small but dedicated team as we approach our 50th anniversary in 2026. We're passionate about transforming lives for people with axial SpA, and this varied role provides essential administrative support that helps us deliver on our mission. The role is 21 hours per week with flexible working arrangements across the week to suit your needs, with at least one day par week in our London office. We need someone who enjoys variety, is comfortable working independently, and takes satisfaction in contributing to the team's success.

WHAT YOU'LL DO

You'll provide varied administrative support including managing correspondence, processing post, sending membership materials, and helping with event administration. You'll maintain accurate records by entering data into Salesforce- our customer database, checking reports match, and organising documentation. You'll also help keep the office running smoothly by liaising with suppliers and assisting with health & safety compliance.

WHO WE'RE LOOKING FOR

You'll have experience in general administrative roles with strong organisational skills and excellent attention to detail. You'll be proficient in Microsoft Office (particularly Excel), reliable, proactive, and able to work independently whilst being a supportive team player. Experience with Salesforce is desirable but not essential.

NASS is the only UK charity dedicated to axial SpA. Recently shortlisted for Medium Charity of the Year, we campaign for early diagnosis, work with the NHS, and support thousands across the UK.

Benefits: Competitive salary, flexible working, 10% pension contribution, 15 days annual leave, plus bank holidays and additional leave over Christmas, hybrid working, professional development, employee assistance programme, and more.

Our culture: We truly value our people. You'll become part of a dedicated team doing meaningful work that directly impacts the lives of people living with axial SpA. This is a role where you will be supported to succeed and genuinely appreciated for your contributions.

We aim for a truly inclusive culture with talented, diverse teams that represent a variety of backgrounds, perspectives, and skills.
