About Harper James
Harper James is a modern, ambitious law firm built to support entrepreneurial businesses with accessible, high-quality legal services. We combine legal expertise with a commercial mindset and a scalable operating model designed for growth. We are one of the first legal services businesses to advertise on OpenAI ads within the UK!
We are now looking for a commercially driven Head of Digital Marketing and Performance to lead and scale our digital acquisition engine.
This is a senior leadership role with significant influence across commercial strategy, growth planning, and performance governance. You will work closely with the CCO, senior leadership team, Business Development, Brand, CRM/Data, Finance, and external partners to build a more predictable, scalable, and commercially effective acquisition model.
The Role
As Head of Digital Marketing and Performance, you will own the strategy, execution, and optimisation of Harper James’s digital acquisition and demand-capture performance.
You will be responsible for improving the quality, efficiency, and commercial value of enquiries across the full digital funnel, from website sessions and qualified enquiries through to SQLs, deals created, and revenue contribution.
This role goes beyond channel management. You will bring commercial rigour, analytical thinking, and strategic leadership to digital growth, ensuring investment decisions are aligned to CAC efficiency, ICP-fit demand, conversion performance, and EBITDA contribution.
You will operate at a senior leadership level, translating digital performance into clear commercial insight, recommendations, and investment cases for executive and Board-level stakeholders.
Key Responsibilities
Digital Acquisition Strategy
- Own and evolve Harper James’s digital acquisition strategy across paid, organic, and AI-led discovery channels.
- Translate revenue targets and go-to-market priorities into commercially governed acquisition plans.
- Drive scalable qualified demand growth while maintaining CAC efficiency, lead quality, and ICP alignment.
- Establish clear operating rhythms including forecasting, reporting, test roadmaps, and performance reviews.
Paid Media and Performance Marketing
- Lead paid acquisition strategy across Google Ads, Microsoft Ads, paid social, YouTube, and emerging AI/search formats.
- Manage agency relationships and performance against commercial outcomes and ROI.
- Optimise channel structure, bidding strategies, conversion signals, and budget allocation to improve efficiency and conversion quality.
- Take ownership of significant acquisition budgets with accountability for performance and revenue contribution.
