Fundraising manager volunteer roles in Durham, county durham

Constantnople Enterprise delivers AI-enabled HDPE fish cages that boost productivity, reduce pollution, and support sustainable aquaculture across Kenya and the broader African region.

Fish farmers often rely on traditional cage systems that lack real-time monitoring and durability, leading to high mortality rates and inconsistent yields. This inefficiency contributes to food insecurity and environmental degradation, as unmanaged systems can cause water pollution and feed waste. With climate change bringing temperature fluctuations and oxygen depletion, farmers need adaptive technology to protect their livelihoods and freshwater ecosystems.

Constantnople provides a high-tech circular solution by integrating durable High-Density Polyethylene (HDPE) cages with an AI-powered monitoring system. Our sensors track water quality parameters like dissolved oxygen and temperature in real time, while data analytics optimize feeding schedules to reduce waste and detect early signs of fish stress. By combining resilient physical infrastructure with digital intelligence, we empower farmers to increase productivity, improve survival rates, and promote responsible management of aquatic environments.

• Ensure applications and supporting documents are consistent, accurate, and submitted within deadlines
• Coordinate light-touch check-ins, task allocation, and updates (weekly or fortnightly, as agreed)
• Help improve systems and templates so the team can work efficiently (for example trackers, folder structure, and standard wording)

Who we’re looking for

Essential

• Proven experience in fundraising (charity, community interest, education, health, environment, or similar)
• Strong understanding of what makes a successful grant or fundraising case, and how to align it to funder criteria
• Confident leading and supporting a small team, with a collaborative and encouraging style
• Excellent written and verbal communication, with the ability to give clear, constructive feedback
• Highly organised, reliable, and comfortable managing multiple deadlines
• Able to commit around 4 hours per week on an ongoing basis

Desirable

• Experience managing a fundraising pipeline or CRM, or maintaining trackers and workflows
• Experience developing fundraising strategy and prioritisation
• Familiarity with UK trusts and foundations, corporate giving, or community fundraising
