The Opportunity
Are you an experimentation specialist who wants to make testing faster, more reliable, and genuinely impactful? Open Partners is looking for a CRO Junior Partner to join our creative optimisation team and power our client growth. Working at the cross-section of data, user experience, and conversion strategy, you will help transform A/B testing from a series of one-off activities into a dependable, scalable engine for performance. You will bring the delivery firepower needed to run high-standard experiments across our portfolio, turning raw results into clear, commercial recommendations that clients trust.
Your Role & Responsibilities
- End-to-End Test Execution: Design, build, QA, and launch live experiments across client websites, ensuring total validity and technical accuracy.
- Roadmap Management: Keep experimentation programmes moving at pace and on scope, preventing blockers and maintaining momentum across cross-functional teams.
- Data-Led Recommendations: Translate raw test data into clear, actionable insights rather than simple readouts, showing clients exactly what to do next.
- Client Advisory: Serve as a trusted point of contact, presenting test strategies, hypotheses, and progress reports to both technical and non-technical stakeholders.
- Process Optimisation: Help build a consistent, repeatable operating system for how experiments are planned, documented, QA'd, and reported across the agency.
- Co-Intelligent Working: Combine your human intelligence with AI workflows to increase the speed, depth, and quality of analysis.

What Success Looks Like in 6 Months
- Trusted Client Relationships: You are seen as a knowledgeable, dependable second point of contact that clients come to directly for optimisation advice.
- Independent Ownership: You independently manage test design, development, QA, and live monitoring alongside your partner.
- Standardised Operations: You have helped establish a consistent operating model that keeps QA issues low, eliminates dropped handovers, and accelerates test velocity.
- Co-Intelligent Output: You routinely use AI-native tools to raise the bar on data reporting, analysis, and strategic roadmap contribution.
What You’ll Bring
- Experimentation Craft: Proven ability to design, build, and QA valid, trustworthy A/B tests from start to finish.
- Analytical Thinking: Strong analytical skills with a track record of turning test data into recommendations that influence decisions.
- Delivery & Coordination: Exceptional organisation skills to hold workstreams together and keep multi-client programmes moving.
- Clear Communication: Ability to explain complex testing concepts and data insights clearly, both in writing and in person.
