This role is for an experienced CRO Specialist who can lead experimentation across client websites and marketing funnels, while acting as the bridge between CRO, PPC and SEO to embed a testing and growth mindset across the agency. You will design and lead tests, translate insights into clear actions for channel teams, and help shape how the agency uses data and experimentation to drive performance.
We are a remote first, Sheffield UK based digital marketing agency that values trust, ownership, and smart, effective work. There is no micromanagement or red tape, just the tools, talent, and support you need to do great work, keep developing, and have real influence on how we grow. We are an award winning conversion focused agency and a Google Premier Partner, with over fifteen years experience helping ambitious brands grow through Paid Advertising, SEO, Creative, and Conversion Rate Optimization. You will join a collaborative, down to earth team where initiative, curiosity, and high standards are genuinely valued.
What You Will Be Doing
- Lead the CRO strategy for a portfolio of clients, from research and hypothesis generation through to test design, implementation, analysis, and reporting.
- Design, lead, and analyse A/B and multivariate tests across landing pages, websites, and key user journeys to improve conversion rates and revenue.
- Act as the bridge between CRO, PPC and SEO, working closely with others to align experiments with traffic strategy, messaging, and technical constraints.
- Develop and champion a cross channel testing roadmap, helping the wider team adopt a structured experimentation framework and growth mindset.
- Use analytics tools, heatmaps, user recordings, and qualitative research to uncover friction points and opportunities across full funnels (from ad click to sale or lead).
- Collaborate with designers, developers, and content specialists to implement winning variants and ensure changes are robust, trackable, and scalable.
- Validate and improve tracking and measurement for CRO experiments in GA or GA4 and ad platforms, ensuring test results are reliable and meaningful.
- Communicate insights and recommendations clearly to clients and internal stakeholders, turning complex data into simple, commercially relevant narratives.
- Contribute to broader agency best practice in measurement, experimentation, and user centric design, sharing learnings across PPC, SEO, and Creative teams.
Remote working and communication
This is a remote first role. For UK residents it would involve one in person team meet up day per month in Sheffield (usually a Friday), plus very occasional client meetings, however, this is not a requirement for non UK based. The team meets via a daily - all day - Google Meet video call for collaboration and planning, so you must be comfortable on camera and in live discussions. You will be expected to maintain reliable internet and be available during 5 hours of the core hours (9am to 5pm UK time), and communicate proactively with colleagues and clients.
What We Are Looking For
- Proven experience in a dedicated CRO, experimentation, or conversion focused role within an agency or in house digital team.
- Strong practical experience with A/B testing and experimentation tools such as Convert.com (ideally), or VWO, Optimizely, AB Tasty, or similar.
- Confident using analytics platforms such as GA or GA4 and Looker Studio to analyse user behaviour and performance data.
- Solid understanding of how CRO interacts with PPC and SEO, including landing page relevance, messaging alignment, and technical constraints.
- Must be a fluent English speaker, with excellent written and spoken communication skills suitable for client facing work and daily video calls.
- Comfortable working with designers and developers. Able to brief UX and UI changes and understand basic HTML, CSS, or JS constraints is a plus.
- A structured, hypothesis led approach to leading experimentation with clear documentation and prioritisation frameworks.
- Curious, commercially minded, and comfortable taking ownership. You enjoy testing, learning, and iterating to find what really moves the needle.
How This Role Bridges CRO, PPC And SEO
- Lead alignment between ad campaigns and landing experiences, ensuring messaging, offers, and user journeys are consistent and optimised for conversion.
- Collaborate with PPC specialists to design experiments that test both traffic and on site elements such as audience, creative, and landing page as a unified system.
- Work with SEO specialists to ensure key pages are both search friendly and conversion focused, balancing technical and UX considerations.
- Coach and support channel teams to adopt experimentation best practices, helping them frame hypotheses, interpret results, and roll out learnings.
Package And Benefits
