About the role

Senior Product Manager for the B2B segment of the Mail & Calendar (Inbox) product, leading strategy and roadmap to serve organizational buyers while preserving Proton’s privacy guarantees.

Responsibilities

  • Own the B2B product strategy for Mail and Calendar in partnership with central B2B leadership and other business units - identify what organizations need (admin controls, org management, integrations, compliance features) and sequence it against consumer priorities
  • Lead features from first principles through post-launch measurement, working directly with Engineering, Design, Marketing, Sales, and Data
  • Talk directly with admins, IT buyers, and org end users to build a first-hand view of workflows, pain points, and buying criteria that shape the roadmap
  • Drive product-led growth initiatives that expand our self-serve B2B flywheel, from trial-to-paid conversion to seat expansion within existing accounts
  • Partner with Sales on pricing, packaging, and feature requirements for larger deals, including scoping what's needed to win against competing offerings
  • Own the integration and ecosystem roadmap (SSO, directory sync, and other tools admins expect to plug into their existing stack)
  • Define and report on B2B-specific health metrics (e.g., seat activation, org retention, expansion revenue) to track product health and inform roadmap trade-offs
  • Anticipate growth ceilings before they arrive: recognize when the product needs foundational investment (tooling, infrastructure, customer engagement platforms) and make the case for it with data

Qualifications

  • 6+ years of PM experience in B2B SaaS, with a track record of shipping features that moved engagement or retention metrics
  • Deep B2B SaaS background: you've owned product for organizational buyers, understand admin and IT workflows, and know how enterprise feature decisions differ from consumer ones
  • Analytically rigorous: you define success metrics before building and can construct a model to pressure-test a roadmap decision, grounding decisions in evidence
  • Technically fluent: comfortable designing solutions with engineers, challenging technical assumptions, and making the right trade-offs when scope and timeline conflict
  • Experienced with freemium or subscription models, with a clear view of how product decisions translate to revenue outcomes
  • A direct, structured communicator who can align skeptical engineers, a growth team with competing priorities, and senior leadership within the same week
  • Background in productivity software, with an understanding of user habits, switching costs, and what makes people come back daily
