Job Description

We're looking for a curious, analytical, and collaborative Junior CRO Manager to join our growing Conversion Rate Optimization (CRO) team. You'll help drive our experimentation programme by identifying opportunities to improve the customer experience and business performance. You'll work across the full experimentation lifecycle, from ideation and test setup to analysis and iteration, working closely with Product, UX, Design, Engineering and eCommerce teams to deliver measurable impact.

This is an excellent opportunity for someone looking to develop their CRO expertise while learning from an experienced team in a fast-paced, data-driven environment.

What you'll do:

• Generate and prioritize A/B test ideas based on customer insights, data, research, and business objectives.
• Develop clear hypotheses and experiment plans.
• Configure, QA, launch, and monitor A/B tests using our experimentation platform.
• Analyse experiment results and translate findings into clear, actionable recommendations.
• Conduct data deep dives to uncover customer behaviour, identify optimisation opportunities, and support business decisions.
• Iterate on previous experiment learnings to continuously improve customer experience and conversion performance.
• Partner closely with Product, UX, Design, Engineering and eCommerce teams to identify opportunities, prioritize experiments, and ensure successful delivery.
• Present experiment results and recommendations to stakeholders in a clear, concise, and compelling way.
• Maintain accurate documentation of experiments, insights, and best practices.
• Contribute to building a strong culture of experimentation across the business.

Who we are looking for:

• 2–4 years' experience in CRO, digital optimisation, web analytics, UX, or a related field.
• Strong understanding of the CRO process, from identifying opportunities through to analysing results and sharing recommendations.
• Hands-on experience with Google Analytics (GA4) or another analytics platform.
• Experience using an A/B testing platform (e.g. AB Tasty/VWO, Optimizely, Adobe Target, Dynamic Yield ).
• Experience in analysing quantitative and qualitative data to generate test hypotheses.
• Experience writing clear test plans, hypotheses, and success metrics.
• Strong stakeholder management and communication skills, with the confidence to present recommendations and results.
• Basic knowledge of HTML, CSS, and JavaScript (enough to understand implementation constraints, not necessarily to code).
• Experience working in agile, cross-functional teams alongside designers, developers, and product managers.
• Fluent English (written and spoken); additional languages are a plus.

Nice to have

• Experience working with e-commerce websites.
• Understanding of UX principles and customer journeys.
• Familiarity with heatmaps, session recordings, and user research tools (e.g. Hotjar, Microsoft Clarity, Contentsquare ).
• Experience prioritizing testing opportunities using frameworks such as ICE, PIE, or RICE .

What we offer:

• Maturing Scale-Up : We’re part of the 13–20% of start-ups that transition to scale-up. This is a rare stage where we refine systems without losing agility. It’s where start-up energy meets scalable impact - and where people can build the next version of Emma.
• Empowerment to Impact : Every Emmie owns part of our success with accountability. It’s about seeing it, owning it, doing it – something that is valued and measured in development.
• Growth & Learning Journey : We live by the 70/20/10 model – with 70% on the job, 20% from others, 10% structured training. We invest in your growth with trainings and coaching to get you to the top of your game.
• Emma-zing Community : We hire selectively which means working with smart, collaborative people who care deeply. It’s a community built by Emmies for Emmies.
• Next Level Global : With 60+ nationalities across 4 offices, global collaboration is part of our values. You’ll work across cultures, perspectives, and time zones.
• Flexibility : Our Technology team's remote work policy allows for great flexibility. (Please note that the role requires being based in Portugal or Germany)
