Principal Product Manager Growth Platform - Lounge by Zalando (all genders)

Role: Principal Product Manager Growth Platform at Lounge by Zalando. The Growth & Lifecycle team owns the growth engine of Lounge, delivering the right message to the right people at the right time to over a million users daily. As Principal Product Manager, you are the marketing-technology expert in the mission's product leadership, owning the product behind the marketing: campaign and product data hubs, the Braze-based lifecycle messaging platform, the layer connecting data-science models to customer communications, server-side tracking and privacy infrastructure, and AI systems that increasingly run marketing autonomously. This is a leading individual-contributor role for an experienced marketing-technology product manager, with the option to mentor senior product managers as the team grows. Responsibilities: - Own the platform product strategy: Define and execute the strategy for Lounge's growth platform — data hubs, messaging infrastructure, feed and content pipelines, automation services — aligned with the mission's charter, commercial goals, and the wider Zalando ecosystem. - Deliver the autonomous-marketing engine: Own the product side of the mission's headline commitment — AI marketing agents for Paid, SEO, and CRM that plan, execute, and optimise campaigns in production — with evaluation pipelines, guardrails, and incrementality measurement. - Build the zero-touch operational backbone: Drive campaign quality assurance from ~50% to fully automated — bots validating deep links, copy, and voucher configurations — and grow the share of revenue driven by automated systems into a headline KPI. - Anchor the product–engineering interface: Represent product in architecture-level decisions with Principal Engineers — APIs, event streams, data models, build-vs-buy — translate technical trade-offs into decisions commercial leadership can own, and manage strategic vendors through evaluation, contracting, and integration. - Make compliance a feature: Ensure personalisation and messaging are GDPR-compliant by design — consent, pseudonymisation, data deletion. - Raise the technical bar of the product organisation: Produce product artifacts that become best practice (PRFAQs, solution designs, KPI frameworks), mentor product managers, and lift the technical fluency of the product team. Qualifications: - Martech understood from both sides: Deep, hands-on experience with modern marketing technology — ESP/CRM platforms (Braze or comparable), customer data platforms, product feeds, campaign automation, server-side tracking — and a real understanding of the marketing practice these systems serve. - Platform product experience: An extensive track record managing marketing or data platforms as products — turning infrastructure into roadmaps, and architecture trade-offs into business decisions. - Technical fluency, without needing to be an engineer: Comfortable in architecture discussions — APIs, event streams, data models, build-vs-buy — fluent enough to represent product credibly with Principal Engineers and lead technical product discovery. - AI-native product leadership: Shipped LLM- or ML-powered products to production — personalisation, triggers, or agentic automation — and can speak concretely about evaluation, guardrails, observability, and what changes when the model changes. - Experimentation rigor: A strong record of hypothesis-driven development — A/B testing at scale, incrementality measurement, and KPI-driven prioritisation. - Bilingual communication: Equally at home in an architecture deep-dive and an executive summary, translating one into the other. - Craft excellence: Written artifacts (strategies, PRFAQs, solution designs) that others reuse as templates; work autonomously in ambiguous problem space. - Scale experience: Built for high-volume consumer products — millions of users, multi-channel, multi-country.
