Senior Product Manager - Customer Facing (m/f/x)

We are looking for a Senior Product Manager to join one of our Customer Facing teams, working along a cross-functional group of engineers, designers shaping how millions of customers buy and sell pre-owned electronics and media on rebuy.

At rebuy, we deeply value collaboration, empathy, and a culture of honest feedback. In this role, you'll own the buying and selling experiences for one of our categories. You'll use data and continuous customer discovery to identify the opportunities that matter most, make smart trade-offs, and ship iteratively to learn fast. You'll work closely with engineering and design to turn insights into measurable outcomes, while keeping stakeholders aligned through clear communication and well-reasoned strategy.

If you thrive on understanding real customer problems, making evidence-based decisions, and balancing speed with quality (and you want your work to directly contribute to making circular living accessible to all) we'd love to hear from you.

Ready to become part of the most important mission on this planet? We are rebuy, pioneers in the sustainable reuse of electronics and media, and we are looking for you! Our mission: to make circular living accessible to all, one transaction at a time. By giving products a second chance, we reduce resource consumption and avoid unnecessary e-waste.

Our team of 600 comes from all corners of the world; we drive things forward collaboratively, take personal responsibility, value positive critical thinking, and persistently serve our customers and planet.

Key Responsibilities:

• Lead Customer Discovery and Validation: Uncover underlying customer needs through regular research, synthesizing qualitative and quantitative insights to identify key opportunities

• Own Product Strategy and Roadmap: Develop a clear, business-aligned roadmap, making prioritization decisions with explicit trade-off reasoning and documenting your thinking

• Drive Iterative Development and Learning: Break down problems into testable increments, sequence releases for rapid learning, and design rigorous experiments to inform next steps

• Make Data-Driven Decisions: Define success metrics, analyze performance data to uncover insights and build business cases, combining all evidence to tell a complete story

• Ensure Cross-Functional Alignment: Collaborate closely with engineering and design teams, and communicate strategy, progress, and expectations with clarity across all audiences

• Identify Opportunities: Proactively spot and build business cases for opportunities beyond your immediate scope without derailing core objectives

• 3+ years of experience in Product Management, ideally in e-commerce, marketplace, or consumer-facing digital products

• Strong analytical skills: comfortable working with data to size opportunities, define metrics, and build business cases

• Experience with continuous discovery practices: customer interviews, assumption testing, and experiment design

• Familiarity with A/B testing platforms and statistical concepts for experiment design

• Proven ability to collaborate with engineering and design teams throughout the product development lifecycle

• Clear, structured communication skills with the ability to tailor messages to different audiences

• Comfort using AI tools (e.g., Claude AI, Gemini, etc) to accelerate daily work such as research, analysis, writing, and prototyping

• Fluency in English (German is a big plus)
