We're looking for a confident, curious, and performance-driven Senior Digital Planner to join our team. This role is central to how we deliver media strategy, optimise campaign performance, and evolve our planning frameworks across paid media.
You'll lead planning across a wide range of paid media channels, including paid search, paid social, and programmatic, using the right mix of platforms to meet campaign goals. You'll turn briefs into actionable plans, evaluate performance data to guide optimisations, and collaborate with cross-functional teams to connect media with creative and client objectives.
This is a hands-on, strategic role for someone who can own campaign planning end-to-end, work in-platform, and help shape how we plan, test, present, and report in a transforming agency environment.
Your Responsibilities
- Lead media strategy for campaigns across paid search, paid social, and programmatic platforms
- Build and evolve full-funnel media plans based on client objectives and audience insight
- Write and present campaign plans with clear rationale, budget phasing, and test recommendations
- Present media strategies and performance insights to clients, both in meetings and written reports
- Design, track, and evaluate A/B tests and optimisations across platform, format, and message
- Work directly in-platform to set up, monitor, and adjust campaign performance as needed
- Interpret campaign performance to shape next steps and feed into client reports
- Work with creative, content and strategy teams to connect media with messaging and user experience
- Support campaign build, QA, and trafficking where needed
- Actively contribute to the improvement of our media planning frameworks, processes and tools
- Stay current on media trends and platform innovations — and bring that thinking to clients and team discussions
What we're looking for
- Proven experience planning and optimising campaigns across a mix of digital platforms (e.g. Google Ads, Meta, LinkedIn, programmatic DSPs, TikTok, Reddit or others)
- Strong understanding of digital media KPIs and how to use data to drive decision-making
- Comfortable presenting plans and results to clients and collaborating cross-functionally
- Experience writing media plans and reporting commentary
- Ability to independently lead planning from brief through to wrap-up
- Experience with campaign testing frameworks and performance innovation
- Comfortable working in-platform or overseeing builds in partnership with support roles
- Familiarity with employer branding, recruitment marketing, or talent audience behaviour is a plus
- Knowledge of Google Tag Manager, GA4, and ATS platforms a bonus
Why join us?
We're in an exciting phase of change. You'll help shape how we plan and deliver campaigns, raise the value of paid media, and strengthen the connection between media strategy, performance and creative. This is an opportunity to influence how we work as much as what we deliver.
