Trekstock Cancer Support is the go-to place for exercise and mental wellbeing support for people in their 20s, 30s and 40s living with and beyond cancer - a group too often overlooked. We exist to help people rebuild their strength, confidence and energy through movement, community and expert-led support, from diagnosis through to life after treatment.

We’re a small, ambitious team building something genuinely transformative, and we’re looking for a passionate and proactive Fundraising Manager to help drive our next phase of growth.

This is a hands-on, relationship-led role at the heart of our fundraising. You’ll take ownership of key income streams including challenge events, corporate partnerships and supporter engagement, helping us grow income while delivering an exceptional experience for everyone who supports Trekstock.

From leading flagship events like Trek This City to developing meaningful corporate partnerships, you’ll play a key role in bringing new people into our community - and keeping them connected to our mission.

If you’re a confident self-starter who thrives in a dynamic environment, loves building relationships, and wants to make a tangible difference to the lives of people affected by cancer, this is an opportunity to take ownership and help shape the future of Trekstock.

About you

You’re a confident relationship-builder who loves making things happen. You’re organised, proactive, and comfortable taking ownership in a small, ambitious team. Most importantly, you care about creating meaningful experiences for supporters and making a real impact.

You’ll bring:

• Experience in fundraising (events, community, corporate or similar)
• Strong relationship management and communication skills
• The ability to manage projects from idea through to delivery
• A self-starter mindset and confidence working independently
• Great attention to detail and experience using a CRM or database

Why join us

• Be part of a small, ambitious charity making a real impact
• Shape the future of Trekstock’s fundraising
• Flexible, hybrid working
• Health and wellbeing support + extra leave (including birthday + Christmas closure)
• A supportive, down-to-earth team culture

Trekstock is committed to building an inclusive team and welcomes applications from people of all backgrounds and experiences.

About Degrees

The Degrees Initiative is a UK-based NGO that builds the capacity of the Global South to evaluate solar radiation modification (SRM) geoengineering, a controversial proposal for reducing some impacts of climate change by reflecting sunlight away from the Earth. Degrees is neutral on whether SRM should ever be used, but we believe that the Global South should be empowered to conduct its own research and to play a central role in SRM discussions. The initiative has been working in different forms for fifteen years, and our work receives worldwide coverage and widespread acclaim. 

We seek a Fundraising / Development Manager to manage relationships with our existing funders and to help bring in new donors and partners to diversify our funding base. This position offers a fantastic opportunity for the right candidate to increase the capacity of a field-leading charity, help empower the Global South, and contribute to one of the world’s most important climate-change debates. If you are an ambitious, relationship-driven fundraising leader with an interest in climate policy, science or global development, this is an opportunity to step into a role with purpose, international influence, and real impact.  

The charity is rapidly scaling up, recently doubling its annual budget to £6 million. Degrees has partnered with leading climate change funders and research partners including the Quadrature Climate Foundation, Open Philanthropy, Crankstart, Navigation Fund, Outlier Projects, LAD Climate Fund and UK Advanced Research and Invention Agency (ARIA). Transparency of funding is essential to our work. We do not accept support from anonymous donors or funding from the fossil fuel industry.

Role

We now seek a full-time team member to build on this base. Reporting to the Chief Operating Officer (COO) and working closely with the Founder & CEO and the Chair of the Trustees, the Fundraising / Development Manager will support and coordinate fundraising efforts aimed at securing multi‑year, diversified funding. He / she will also introduce robust processes for pipeline management and donor stewardship, and will support and coordinate the complete donor lifecycle (from identification to cultivation to solicitation and stewardship) of a portfolio of top prospects. The post holder will receive initial onboarding support from the Senior Philanthropy Advisor. As fundraising grows, the team may expand in the future.

Initial priorities include expansion beyond the current donor pool, with a strong push to engage new funders, and putting in place the systems (CRM, reporting cadence, key performance indicators) to support growth at scale.

As this is a new role, responsibilities are expected to evolve but some key items will include: 

Strategy & planning

• Work with the CEO, COO, Senior Philanthropy Advisor, the Chair of the Trustees, and other senior staff to support the development and implementation of a multi-year fundraising strategy aligned with organisational objectives; 

Pipeline development & new opportunities 

• Maintain and coordinate the fundraising pipeline, supporting the fundraising activities of senior staff and the Chair; 

• Support the identification and development of new funding opportunities from trusts and foundations, government funders, and multilateral donors in the development and climate sectors on an ongoing basis; 

• Reach out to networks of climate philanthropy advisors for referrals; 

• Manage contact with funding opportunities; 

Grant writing 

• Draft and coordinate the preparation and submission of grant proposals; 

Donor stewardship & reporting 

• Maintain excellent relations with existing funders by keeping them informed on charity and sector updates, inviting them to events, and ensuring the delivery of annual reports and notices; 

• Ensure and manage ongoing reporting; 

Events & engagement 

• Working with the Events Manager, help design and deliver fundraising events for existing and potential funders, particularly in the UK and US; 

• Manage invitation lists, track attendance and ensure bespoke follow-up to attendees; 

• Assist in the design of events that will inspire and engage funders while involving Southern experts in the Degrees research community; 

• Coordinate all fundraising outreach and related programming for the Degrees Global Forum (a conference to be held in 2027); 

Processes, systems & administration 

• Support the development and implementation of structured processes across the entire fundraising and donor lifecycle; 

• Develop and track KPIs, providing regular reports to senior staff and the Trustees; 

• Be responsible for fundraising data, contacts and administrative records. 

Qualifications 

Essential 

• At least ten years’ experience in fundraising or transferrable relevant experience;

• Track record of helping secure six- and seven-figure grants income from foundations, major individual donors, and/or public agencies; 

• Strong organisational and project management skills; 

• Experience and comfort with Microsoft 365, fundraising CRMs and other common software tools; 

• Experience organising events; 

• Ability to write clearly and communicate effectively in English with a keen attention to detail; 

• Strong interpersonal and relationship building skills, including an ability to work with people of all levels and backgrounds; 

• Experience creating and maintaining fundraising processes; 

• Ability to adapt and remain comfortable in a dynamic, remote start-up environment in a small organisation; 

• Ability to travel internationally; 

• Legal right to work in the UK. 

Desired

• Experience successfully fundraising from climate donors; 

• Experience with a strong network of international funders; 

• Experience building and scaling a fundraising effort; 

• Experience supervising staff (as we expect the team to grow in future); 

• Tech savvy and eager to work with new software solutions; 

• Knowledge of climate science, policy and SRM. 

Benefits of working at Degrees 

• You will join a growing and dynamic charity operating at the intersection of climate change and global development.

• You will have the opportunity to contribute to a potentially high-impact issue by helping shape global conversations on climate science, empowering researchers in the Global South, and collaborating with some of the world’s leading SRM experts.

• The role is fully remote, allowing you to live anywhere within the United Kingdom. The charity has no central office and offers each employee up to £250 per month (including VAT) to cover co-working space costs. The team meets face-to-face at quarterly ‘awaydays’ in the UK, which are organised and paid for by the charity.

• Degrees provides an 8% employer pension contribution with no required employee contribution, which is generous by the standards of the UK third sector.

• The role includes opportunities for international travel.

• You will receive 36 days of annual leave per year, including UK public holidays.

• Personal development budget of £1,000 per year.
