Junior CRO specialist

Join the Product Growth Team to develop core CRO skills by designing and running A/B tests alongside experienced mentors. You'll work on hypothesis development, rapid prototyping, and translating data insights into testable ideas while contributing to real business growth for one of Europe's leading EdTech platforms.

What you'll do

• Form hypotheses and design experiments – from data observation to test hypothesis to test launch.
• Create sketches and rapid prototypes to visualize test concepts before handoff to engineering.
• Develop the data-to-hypothesis-to-test flow – build the skill of identifying signals in data and turning them into testing opportunities.
• Collaborate with design, engineering, and analysts to translate testing concepts into implementation.
• Document and present experiment results with support from the team, developing your ability to communicate findings clearly.
• Maintain a clear pipeline of experiments based on impact, effort, and learning value.

What you'll need

• Exposure to A/B testing, user research, or analytics in any capacity.
• 1–2 years of experience in growth, product, UX, or data-adjacent roles.
• Ability to think in hypotheses – not just "what if" but "why would this work?".
• Strong curiosity about user behavior and a desire to learn conversion optimization.
• Comfort with data and ability to interpret it and familiarity with GA4 or Amplitude (or willingness to learn quickly).
• Ability to produce sketches or simple wireframes (Figma, pencil & paper – no advanced design needed).
• Fluent in English.

What they offer

• Flexible working hours and remote-first model.
• Regular team events, both online and in person at Berlin office.
• Public transport subsidies or fitness club memberships.
• Two additional paid days off per year for voluntary work, plus paid time off on Christmas Eve and New Year's Eve.
