About Bite Back

We’re surrounded by junk food. From the moment we're born, every second of every day, children are being targeted. Giant companies manipulate them with colourful, cuddly, clever marketing, deceive them with packaging claims and pump products at them that are full of junk. It's become the cultural wallpaper. Now, it risks destroying the health of a generation.

Over a third of 10/11-year-olds leave primary school with an increased risk of developing food-related conditions like type 2 diabetes and heart disease in their future.

The good news is, it's totally preventable. And we're biting back.

Bite Back is a youth activist movement challenging a food system that's been set up to fool us all.

We do this by:

1. Calling out the manipulation of the junk food giants.
2. Demanding higher standards from food marketing and from everyday food itself.
3. Mobilising and equipping young people in the fight for better food.

We do all this so we can bite back against a global epidemic of food-related ill health.

Role Description

In this new role the Impact and Evaluation Manager will be critical to helping Bite Back demonstrate and strengthen the difference we make for young people, funders, partners, and wider society. You will lead the organisation’s approach to measuring, evaluating and learning from our work — ensuring that youth voice is at the heart of how we design, assess and communicate our impact. You will manage Bite Back’s relationships with external evaluators, develop and track organisational KPIs, and work closely with programme and fundraising colleagues, trustees and funders to ensure we can evidence our outcomes clearly and compellingly. This role will also develop creative ways to tell the story of our impact — from robust evaluation reports through to case studies that bring young people’s voices to life.

Responsibilities

The Impact and Evaluation Manager is accountable for:

Strategy and Theory of Change

• Working closely with the CEO to lead Bite Back’s organisational impact strategy, including refining and maintaining our theory of change.
• Translating our theory of change into clear outcomes, indicators and learning questions that guide programme design, campaigns and organisational priorities.
• Designing and overseeing Bite Back’s impact measurement framework.

Data Systems and Standards

• Leading on the collection, analysis and reporting of both quantitative and qualitative data, ensuring that youth voice and lived experience shape Bite Back’s evaluation approaches.
• Supporting the development and monitoring of KPIs across the organisation, providing clear insights and recommendations to the Leadership Team.

Donor monitoring and evaluation

• Working with fundraising and programme teams to design robust monitoring, evaluation and learning plans for funding bids, including developing outcomes frameworks, indicators, and evaluation budgets that align with Bite Back’s broader organisational impact framework.
• Working closely with the Senior Grants and Fundraising Manager to ensure Bite Back meets its impact and reporting commitments to funders.
• Leading on the development of Bite Back’s annual impact report and supporting the production of other compelling case studies, impact reports and evaluation outputs to communicate Bite Back’s effectiveness to funders, trustees, partners, the media and wider audiences.

Building a Learning Culture

• Managing relationships with external evaluators, ensuring projects are delivered on time, on budget and to a high standard.
• Building evaluation capacity across the team, providing tools, training and support to colleagues to embed a culture of learning and continuous improvement.
• Embedding equity, diversity and inclusion principles in Bite Back’s impact and evaluation work, ensuring methods are inclusive, accessible and reflective of the communities we work with.
• Acting as a champion for a learning culture, communicating clearly and accessibly about impact, data and evidence, and supporting colleagues through changes to systems and ways of working.
• Staying up to date with best practice in youth-led evaluation, impact measurement and social change movements, and bringing innovative approaches into Bite Back’s work.

Skills and Experience

The ideal candidate would have the following:

Essential

• Experience of designing and delivering monitoring, evaluation and impact measurement, including both qualitative and quantitative methods.
• Understanding of youth voice and participatory approaches to evaluation — particularly with young people and/or marginalised groups.
• Strong analytical skills, with the ability to turn complex data into clear, actionable insights.
• Experience of creating compelling case studies and impact reports for different audiences (including the media, funders, trustees, policy makers and of course young people).
• Strong commitment to DEI: experience in designing or implementing evaluation methods that are inclusive and equitable, ensuring marginalised voices are heard.
• Strong project management skills, able to manage multiple projects and external relationships at once.
• Excellent communication skills — written and verbal — with the ability to engage and inspire different stakeholders.
• A commitment to Bite Back’s values: Fresh, Resilient, Respectful, Energetic, Real.

Desirable

• Experience of managing relationships with external evaluators, researchers, or consultants.
• Knowledge of impact measurement in campaigning, advocacy or youth engagement contexts.
• Familiarity with digital tools for data collection and analysis (e.g. survey software, data visualisation tools).
• Experience of working in a charity or social movement environment.
