About Proton
Join Proton and build a better internet where privacy is the default
Proton is one of Europe's fastest-growing technology companies, serving over 100 million users worldwide. Founded in 2014 by scientists who met at CERN, we've built a trusted ecosystem of privacy-first products — Proton Mail, Proton VPN, Proton Drive, and Proton Pass.
Our mission is to create ethical, secure alternatives to Big Tech by putting privacy, transparency, and user trust first. We're profitable, independent, and funded by our community — not venture capital. Today Proton employs 500+ people across 50+ nationalities, headquartered in Geneva with offices across Europe and beyond.
As we scale our B2B business, CRM and lifecycle marketing are becoming critical growth engines. We're looking for a CRM & Lifecycle Marketing Lead to own, unify, and scale lifecycle strategy and operations across both segments.
The role
This is a senior individual contributor role, for someone who can set a B2B CRM & Lifecycle strategy and build it themselves. You'll own Proton's B2B CRM & Lifecycle programs end to end, from first touch to renewal and expansion, and operate as the authority for Proton for Business.
Our B2B motion is hybrid: businesses buy through a self-serve and sales-led motion, and through partners and MSPs. HubSpot is implemented but still early in its maturity. Your mandate is to close the gap between what it can do and what it delivers today, by building the lifecycle architecture, automation and data foundations that turn sign-ups and leads into pipeline, paying accounts, adoption and expansion.
You'll be equally comfortable designing a lifecycle framework, configuring the platform that runs it, and digging into the data to prove it works. You know which product events, account attributes and intent signals each program needs, and you work closely with RevOps, Data and Martech to get them into the CRM. You operate through influence and systems ownership rather than headcount, and you've done this before in a fast-moving B2B SaaS scale-up.
What you'll do
B2B lifecycle strategy
• Own the end-to-end B2B lifecycle strategy across self-serve, sales-led and partner motions.
• Define and operationalise the core programs: lead nurture, trial and admin onboarding, seat activation and adoption, renewal, churn prevention, plan upgrade, cross-sell and win-back.
• Design at both contact and account level, reaching the admin, the economic buyer and end users with the right message at each stage.
• Embed lifecycle thinking across Marketing, Sales, Customer Success and Product.
CRM operations
• Take Proton's CRM from early-stage to mature, fully operationalised use, as owner and primary admin of the marketing side of the platform.
• Establish clean lifecycle-stage and lead-status definitions, robust lead and account scoring, including product-qualified signals from self-serve usage.
• Build and run MQL to SQL orchestration with
