About this role
Join Proton and build a better internet where privacy is the default
Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right . Since then, we've built the world's largest encrypted email service (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar - tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives.
We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 700+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics.

The Role
Proton runs a growing portfolio of SaaS products: Mail, VPN, Drive, Pass, and Calendar - each generating its own signals about how users adopt and engage. Today, communication across that portfolio is built product by product, which means users can receive fragmented or overlapping messages instead of one coherent experience. This role exists to fix that: build the lifecycle strategy, systems, and operating model that turn user behaviour and product data into coordinated, automated journeys across the whole portfolio. It's a senior individual contributor role reporting into Head of Digital Marketing, working daily with Product, Data, Engineering, and Marketing. You'll thrive here if you'd rather build the operating system for lifecycle marketing than run campaigns inside one that already exists.
What You'll Do
• Own end-to-end B2C lifecycle strategy and operating model: from onboarding and activation through engagement, conversion, retention, cross-sell, and reactivation (starting with onboarding, activation, and engagement before expanding scope).
• Design and orchestrate multi-product customer journeys across Proton's SaaS portfolio: define who receives which message, through which channel, and when, with sequencing, frequency, and suppression rules that prevent conflicting or overlapping communications.
• Translate behavioural and product signals into automated, triggered journeys, partnering with Data and Engineering to define the events, attributes, and integrations lifecycle marketing depends on.
• Build the operational foundations for lifecycle marketing to scale: segmentation architecture, campaign and journey processes, and testing, QA, and governance standards.
• Set measurement frameworks across activation, engagement, conversion, retention, cross-product adoption, and customer lifetime value, and use experimentation to continuously improve journey performance.
• Act as the connector across Product, Growth, Data, Engineering, and Marketing — turning loosely defined problems into scalable programmes and leading through in
