Sr. Product Marketing Manager

Cambridge, MA

Sr. Product Marketing Manager

2025 is set to be a huge year for Proton. We just wrapped up our best year yet in 2024, and now we’re going all in. The GTM team is growing fast—more BDRs, two founding AEs, and additional CSMs—so alignment and enablement are more important than ever. At the same time, we’re introducing significant updates to our offerings, which means we need someone to lead the charge in getting these to market.

That’s where you come in. As our Sr. Product Marketing Manager, you’ll own the rollout of our biggest features, making sure they land with customers and get prospects excited to buy. You’ll make sure Sales and CX have everything they need—messaging, battlecards, training—to crush their goals. And you’ll help us stand out in a crowded market by turning what we build into something people can’t wait to use.

Your success will be measured by key performance indicators such as revenue growth, market share, competitive win rates, and expansion. You’ll have the opportunity to make a real difference—from influencing product strategy and roadmap to delivering insights that will position Proton as a leading CRM in distribution.

What you’ll do:

  • Product launches: Work with Product to ensure every feature and add-on we release—ranging from major launches to minor enhancements—has a clear plan for success. You’ll take the lead on developing messaging frameworks, planning launches, and ensuring customers see the value in both significant updates and iterative improvements right away.
  • Sales & CX enablement: Equip Sales and CX teams with the training, tools, and resources they need to succeed. You’ll create onboarding materials, build a library of content like solution briefs and use-case guides, and help teams confidently communicate product value.
  • Pricing & packaging: Launch and support our new pricing tiers, making it easy for customers to understand the benefits of upgrading and aligning pricing with value.
  • Positioning & messaging: Develop sharp, no-nonsense messaging that explains what Proton does, why it matters, and how we’re different.
  • Customer insights: Get inside the minds of our buyers. Talk to customers, shadow users, and listen to discovery calls to understand their challenges, needs, and how they describe their problems. Use these insights to refine messaging and inform our marketing strategy.Competitive insights: Keep tabs on the market and create materials like battlecards to give Sales the edge in competitive deals. Make sure everyone at Proton knows how we stack up and can communicate it clearly.
  • Collaborate across teams: Be the go-to expert on our customers—key personas, their pain points, and what makes them tick. Partner with Product, CX, and Sales to make sure everyone is aligned and equipped to deliver on Proton’s potential.
  • Customer Advisory Board (CAB): Set up and lead a CAB to create stronger feedback loops with customers, learn what’s working (and what’s not), and shape our product and go-to-market strategy based on what they need.

What you’ll need to succeed:

  • 5+ years of experience in product marketing at a high-growth SaaS company.
  • A knack for building go-to-market strategies that make new product features and releases resonate with customers.
  • The ability to write clear, concise product copy and craft stories that connect features to real customer problems and outcomes.
  • Strong communication skills—you can take something complex and explain it simply, without oversimplifying.
  • A head for numbers—you know how to track what’s working, optimize what’s not, and use data to drive decisions.
  • You’re organized and can juggle multiple projects without dropping the ball.
  • A bias for action—you roll up your sleeves, figure things out, and make things happen, even with a small team.
  • You thrive in the unknown. Ambiguity doesn’t stress you out—it motivates you.
  • Bonus points if you’ve had success creating and managing initiatives like customer advisory boards.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
