Job (35h, UK): Mobilisation Expert


About more onion

More onion is a digital mobilisation agency supporting progressive non-profits all over Europe with digital campaigns and fundraising. Our team is based in Austria, Germany and the UK.


Our agency work combines strategy consulting, creative communications and hands-on delivery of campaigning and fundraising projects. More onion also offers a software platform for organisations, called Impact Stack.

We have adopted an organisational structure where every client has a main contact person who is a Mobilisation Expert. Your role will therefore be both to manage client relationships and deliver projects. 

Your role

You will:

  • Work with clients to develop robust strategies for their campaigns, fundraising and communication projects
  • Work with clients to execute those strategies including in many cases hands-on work to build, test and optimise pages and email journeys
  • Monitor and analyse the performance of supporter communications and work to optimise them against their objectives
  • Collaborate with the wider team on large projects, from copywriting, design and technology to create engaging and impactful supporter experiences
  • Work with our Business Development Director to help shape projects before they begin
  • Develop and maintain strong client relationships
  • Develop and deliver trainings to charity sector professionals, both online and in person.
  • Provide input into the future development of our mobilisation platform Impact Stack, to ensure it continues to be as effective as possible for our clients
  • As a team member you participate in activities of the wider organisation, support colleagues, learn together, improve our process and provide input into business development

What we're looking for

  • Minimum of 2 years of experience in the charity sector in the field of mobilisation, digital campaigning and/or digital fundraising
  • Hands on experience delivering digital campaigns
  • Fast learner
  • Flexible when it comes to specific tasks and the types of projects you deliver
  • Excitement about working with non-profits, NGOs, charities, unions and progressive organisations
  • Clear, pro-active communications in writing as well as conversations
  • Ability to work fairly independently as a member of a tightly knit team
  • Ability to confidently manage your own time
  • Strong project management skills
  • Fluency in both written and spoken English

Nice to have:

  • Knowledge of the UK political systems and influencing strategies
  • Strong understanding or and/or connections within the UK charity sector

You don't meet all of these criteria? Feel free to reach out and tell us why you think you are the right candidate anyway.

What we can offer:

  • A fairly independent role at an innovative company, where we practice what we preach and we're never afraid to try new things
  • Working for well-known international charities and helping them create impact
  • A team that has established processes, many years of experience and a very detailed understanding of the sector and clients need
  • A wonderful team with a friendly culture and supportive colleagues
  • A work environment where learning, innovation and improvement is celebrated
  • Flexible working hours (as long as clients and colleagues are happy)
  • Flexible choice of workplace within the UK, with a preference for London
  • 25 days of annual leave (pro rata), increased by one day annually up to 28 days
  • A salary depending on experience and location: £38,000- £44,000 pro rata*, plus £3,000 London weighting where applicable

*Full time is 40 hours. We are also open to candidates looking to work the full 40 hours a week instead of 35.
