A new and exciting opportunity has arisen for a Digital Marketing Officer (0.6 FTE / 22.5hrs per week) with strong digital marketing skills and passion for engaging content.
You’ll be joining the only independent charity in the UK dedicated to improving the nation’s numeracy. It’s a fantastic opportunity within a small but ambitious and dynamic organisation making a real difference to people’s lives and livelihoods.

Harris Hill is thrilled to partner with Christian Aid, to hire their new Digital Performance Advisor, to work in either London, Cardiff, Edinburgh or Warrington. The Digital Performance Advisor will be the driving force behind understanding and improving their online performance. This role is central to how they use data and insight to make impactful decisions across digital, fundraising, campaigning and supporter engagement.
You will strengthen Christian Aid’s digital measurement, analytics and reporting capability, enabling colleagues to ask questions, understand user behaviour and act on clear, actionable insights. This role focuses on analysis, interpretation and strategic advice — ensuring digital activity is informed by robust evidence and aligned with organisational values and goals.
This is a specialist analyst role and the organisation’s subject matter expert in Google Analytics 4 (GA4).
About you:
You are an experienced digital analyst with deep expertise in Google Analytics 4. You specialise in analytics, insight and performance measurement, and you enjoy making sense of complex data to answer real organisational questions.
You are confident explaining how GA4 works, how funnels and lifecycles are structured, and how campaign activity translates into meaningful outcomes.
Essential skills and experience:
- Proven expertise in digital analysis and insight, with experience producing data-driven reports and actionable recommendations
- Advanced GA4 knowledge, including funnels, segmentation, lifecycle reporting and (where relevant) e-commerce tracking. Strong understanding of the transition from Universal Analytics (GA3) to GA4 and its implications
- Experience using tools such as Looker Studio, Power BI, and behavioural analytics tools (e.g. Hotjar, Contentsquare)
- Ability to interpret A/B testing and experimentation results to inform optimisation decisions
- Experience managing tracking requirements, tag management and integrating digital data with CRM systems
Why this role is unique:
- True GA4 ownership: You will be Christian Aid’s subject matter expert in Google Analytics 4, with real responsibility for how GA4 is used, developed and embedded across the organisation. This is not a shared or junior analytics role — your expertise will shape best practice.
- Strategy over button-pushing: This role focuses on insight, interpretation and influence, not day-to-day campaign optimisation. You’ll answer the “why” behind performance and help teams make better decisions, rather than simply reporting metrics.
- Built, not starting from scratch: GA4 is already implemented, giving you a strong foundation to improve structure, governance and reporting, and to unlock deeper value from existing data.
Do you want a voice at the table? Your analysis will directly inform strategic decisions, helping colleagues across the organisation understand users, test improvements and optimise digital experiences.
