Technical CRO Manager (Frontend Experimentation)

I'm hiring a Technical CRO Manager for one of the UK's leading customer acquisition businesses.

This is a rare opportunity to build and own an internal CRO capability from the ground up, taking responsibility for experimentation across multiple high-traffic lead generation brands while helping shape the future of the CRO function.

Unlike many CRO roles, this isn't purely strategy and analysis. They need someone who can combine experimentation expertise, commercial thinking, and hands-on front-end testing skills.

A fast-growing international marketing and technology business operating across the UK, USA, Canada, Australia, and France.

They own and operate their own digital brands rather than acting as an agency, giving them complete control over customer acquisition, experimentation, and optimisation across the customer journey

With 40+ lead-generation journeys and significant investment into paid search and paid social, there is huge scope to drive measurable commercial impact through experimentation.

The business has invested in CRO through external contractors for the last couple of years and is now bringing the capability in-house.

You'll take ownership of:

• The CRO roadmap
• Experimentation strategy
• Testing frameworks
• Front-end test implementation
• Future team growth

As the function matures, there is a genuine opportunity to build and lead a dedicated experimentation team.

• Own the CRO and experimentation roadmap across multiple brands
• Design, build, and analyse A/B testing programmes
• Create a structured, high-velocity testing pipeline
• Build and validate experiments using:
  • HTML
  • CSS
  • JavaScript
• Manipulate the DOM and deploy front-end tests using Convert.com or comparable platforms
• Use behavioural analytics tools such as Mouseflow, Clarity and FullStory to identify optimisation opportunities
• Prioritise testing opportunities based on commercial impact, traffic volumes and lead quality
• Present recommendations and business cases to senior stakeholders
• Work closely with Marketing, Technical and Compliance teams to drive growth

• 5+ years dedicated CRO experience
• Experience running end-to-end experimentation programmes
• Strong A/B testing and experimentation methodology knowledge
• Strong statistical understanding and test analysis skills
• Commercial mindset focused on revenue and profitability
• Excellent understanding of UX and customer journey optimisation

• 3+ years commercial experience using:
  • JavaScript
  • HTML
  • CSS
• Experience implementing front-end tests yourself
• Experience with Convert, Optimizely, VWO, AB Tasty or similar platforms
• Experience using session replay and behavioural analytics tools

• Lead generation experience
• Agency experience
• Previous mentoring or team leadership exposure
• Experience helping build CRO functions

• Build an internal CRO capability from scratch
• Own experimentation across 40+ customer journeys
• Significant leadership backing for CRO investment
• Genuine progression into team leadership
• High levels of autonomy and ownership
• Blend of strategy, experimentation, front-end development, and commercial impact
• International business with ambitious growth plans

• Up to £60,000 salary (potential flex to £65k)
• Bonus scheme
• Remote first working (2 days/month in Macclesfield)
• Private medical insurance
• Gym membership
• Life insurance
• Team socials and events
• Clear progression opportunities

• Initial interview with Marketing leadership
• Practical experimentation framework task and presentation
• Final interview with senior stakeholders

If you're a CRO professional who still enjoys getting hands-on with experimentation code, while also wanting the opportunity to build a function and influence strategy, this is an outstanding opportunity.
