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.

The Performance Marketing Team at Proton for Business serves organizations that genuinely can’t afford data leaks—journalists, activists, government bodies, and enterprise security teams. The Performance Marketing team owns paid acquisition across all of Proton’s products, with B2B now a strategic growth priority. You’ll work directly with the Performance Marketing Lead, running campaigns end-to-end across Google, LinkedIn, and beyond—while managing an external agency and partnering with the Ad Tech, Brand, and B2B product teams.

What You’ll Do

  • Own end-to-end paid B2B campaigns across Google, LinkedIn, and Meta—from brief to creative to budget to optimization—with full accountability for CPL, ROAS, and CAC.
  • Manage and performance-manage an external performance marketing agency: set briefs, oversee execution, evaluate results, and hold them to the same bar you hold yourself.
  • Implement and maintain privacy-first tracking and attribution frameworks that work without relying on third-party cookies.
  • Forecast quarterly budgets and KPIs, own the delivery, and report performance with clear insights and recommendations to the Performance Marketing Lead.
  • Identify and fix conversion bottlenecks across B2B funnels in collaboration with product teams across Proton Mail, Drive, VPN, and Pass.
  • Partner with the Ad Tech team to automate reporting and campaign processes, reducing manual overhead and improving data quality.
  • Drive creation of campaign assets across B2B product lines to acquire new business leads and clients.

Who You Are

  • 4+ years of hands-on performance marketing experience with a clear focus on B2B user acquisition.
  • Deep platform expertise across Google Ads, LinkedIn Ads, and Meta.
  • Proven track record of delivering measurable ROI (CPL, ROAS, CAC) through paid campaigns for B2B tech or SaaS products.
  • Experience managing an external performance marketing agency.
  • Comfortable designing and implementing privacy-preserving attribution.
  • Strong Excel skills for budget forecasting, reporting, and tracking.
  • Experience with marketing automation and lead nurturing tools (HubSpot or comparable).

Nice to Have

  • Familiarity with CMS tools and landing-page A/B testing.
  • Basic coding or automation skills for reporting efficiency.

  • A Great Team: Diverse, collaborative, and tight-knit.
  • Technology: The right hardware and software to do your best work.
  • Learning & Development: We invest in your growth.
  • Employee Benefits: Strong health coverage, solid retirement options, generous leave, and wellness support.
