About the role
Ruby Labs is a leading technology company specialising in innovative consumer products across multiple technology sectors. The company focuses on D2C (Direct-to-Consumer) subscription products. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ We are looking for a Senior Growth Product Manager to launch new funnels from zero to one for one of our core D2C subscription products. You will join a growth squad where each Growth Product Manager owns one funnel end to end, working closely with the Head of Product, creative, and analytics. You will be fully responsible for the full lifecycle of your funnel - market and competitor research, offer and funnel design, build and launch, acquisition angles, and post-launch conversion growth. This is a hands-on role suited for someone who has already built and launched high-converting web funnels and treats every funnel decision as a hypothesis to be tested. Opinions without data, experiments without decisions, and effort without measurable impact are not acceptable. You are expected to move fast, use AI tooling as a core part of your workflow, and own outcomes from first concept to production. The bar is high and so is the upside - performance here is directly and significantly rewarded, and strong operators take on bigger scope fast.
Responsibilities
- Research & Funnel Strategy
- Run market, audience, and competitor research to define funnel concepts and offers.
- Tear down competitor funnels, extract structural insights, and design superior user experiences.
- Define the value proposition, pricing hypothesis, and funnel structure ahead of the build.
- Funnel Build & Launch
- Launch new funnels end to end - structure, copy, wireframes - from first concept to live.
- Use AI tools to produce copy variants, UX concepts, and functional prototypes quickly.
- Brief design and engineering with clear specs, owning quality, tracking, and launch readiness.
- Acquisition Angles & Creative Concepts
- Develop the selling angles, hooks, and messaging for how your funnel is sold to customers.
- Work closely with the creative team to turn angles into ad concepts for paid social.
- Feed funnel and audience insights back into acquisition messaging.
- Post-Launch Growth & Experimentation
- Build and run the A/B testing roadmap prioritised by expected revenue impact.
- Scale CVR and ARPU through structured experiments - pricing, flows, and retention mechanics.
- Identify and act on drop-off and friction points using Mixpanel funnel and cohort analysis.
Requirements
- Must-Have Experience
- 2+ years in growth product management, CRO, or funnel ownership with verifiable conversion results.
- Track record building and launching at least one web funnel from zero to live, with measurable results.
- Competitor research and teardown work that directly shaped a shipped funnel.
- Strong funnel copywriting and offer-development skills - able to write and structure a funnel independently.
- Experience developing acquisition angles or creative concepts for paid social.
- Hands-on proficiency in Mixpanel: funnel builds, cohort analysis, and event-level reporting.
- Active daily use of AI tools (Claude or equivalent) to accelerate concept, copy, and prototype work.
- Leadership Attributes
- Operates with full ownership - takes a funnel from concept to production without hand-holding.
- Thinks in systems: builds repeatable processes around research, launch, and testing.
- Analytically rigorous - conclusions are supported by data, not intuition or effort narratives.
- Communicates findings clearly and concisely across product, creative, data, and leadership stakeholders.
- Location
- Ruby Labs operates within the CET (Central European Time) zone. Applicants from any country are welcome to apply for the position as long as they are located within approximately ± 4 hours of CET. This ensures optimal collaboration and communication during working hours.
