About Us:

The wholesale distribution industry is ready for a revolution, and Proton is leading the charge. The world relies on distributors to sell nearly every physical product, but despite its massive contribution to the global economy, this industry has been left behind in terms of technology. Proton is changing that. With AI-powered sales software, we’re breaking through the complexity of selling millions of products and making it easier for distributors to anticipate customer needs. Our mission is to bring the distribution industry into the modern age and the results speak for themselves. Distributors using Proton see 10x ROI, faster new hire ramp-up, and happier sales teams.

In 2022, we raised a $20M Series A backed by Felicis Ventures (investors in Twitch, Shopify, Opendoor, and many others) and Battery Ventures. This year, we’re laser-focused on driving customer growth. If you’re excited about the opportunity to wear multiple hats, and continuously learn and experiment, now’s the time to join the Proton team.

The Role:

Why you should apply:

Proton is at an inflection point. We started as a CRM for distributors, and now we’re expanding into a multi-product platform. More products to take to market. More problems to solve. More opportunity for a product marketer to make a real impact. We’re looking for a strategic product marketer who knows how to turn product into pipeline. You’ll own go-to-market for new capabilities, sharpen our positioning in a competitive space, and arm Sales with stories that win.You’ll report to our Head of Marketing and work closely with Product, Sales, and our CEO. From day one, you’ll be executing on the core pillars of product marketing—positioning, messaging, enablement, and launches.We move fast, bias hard toward action, and stay close to the customer. If you want real ownership and the chance to directly shape how a startup makes the leap from product to platform, this is the role. 

Comp: $100k-$160k

Note: We care more about drive than a perfect résumé. Maybe you’re running content, sitting in customer success, or doing something else entirely — and you’ve been itching to break into product marketing. If you’re hungry to learn, curious about customers, and not afraid to hustle, apply anyway.

What you’ll own and run with:

• Positioning & messaging: Develop sharp, no-nonsense messaging that explains what Proton does, why it matters, and how we’re different.
• 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.
• Enablement: Create talk tracks, collateral, and resources that help Sales confidently explain and sell what we offer.
• 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 intelligence: Track market shifts and competitor activity to inform messaging and differentiation.
• 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.
• AI leverage: Figure out how AI can make you better at your job—whether it’s scaling customer insights, accelerating launches, or uncovering competitive angles.

Who you are:

• 3–5 years of product marketing experience in B2B SaaS
• You thrive in the unknown. Ambiguity doesn’t stress you out—it motivates you.
• A knack for building go-to-market strategies that make new product features and releases resonate with customers.
• Bias for action—you dive in, figure things out, and make progress, even when it’s your first time tackling something.
• 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.

Benefits:

• Competitive salary, quarterly performance bonuses, and meaningful equity
• Company-sponsored 401(k) program
• Health, dental, and vision insurance
• Unlimited PTO (and we mean it—we want you to take time off)
• Professional development (get that book, take that course, attend that conference)
• Encouragement to explore and adopt new AI tools that make your work faster and smarter
• Incredible training and career growth opportunities
• A friendly, inclusive, human-first team culture with a strong mix of hustle, productivity, and fun

We're Proton. We build AI-native software for the distribution industry—an $8 trillion market that tech forgot.

We're the #1 AI-powered CRM for distributors. And we're not stopping there. Our second product is live and growing fast. Another new product launches in March. Then more.

We’re hiring a Professional Services Manager to own and scale implementations at Proton. This is a hands-on leadership role managing a team of 7, guiding technically complex implementations, and owning onboarding from kickoff to go live. You’ll be a part of the Customer Experience team as our first Professional Services leader, reporting into the Head of CX.

Our Professional Services work ranges from $30k to $200k and regularly involves custom integrations, including building APIs that don’t already exist. This role sits directly between customers and engineering, taking on complex delivery problems and writing the playbook as you go. The salary will be between $150k-180k + equity.

What you’ll do

Build for scale

Define how Professional Services operates at Proton. Create and refine playbooks, processes, and tooling. Identify bottlenecks and put durable solutions in place. Partner closely with Sales, Customer Success, Product, and Engineering to improve handoffs and execution.

Own delivery

Oversee onboarding and implementation projects from kickoff through go live. Stay close to complex integrations and engineering tradeoffs. Act as the escalation point when scope, timelines, or technical decisions need clarity. Ensure customers reach value quickly and confidently.

Lead the team

Manage 3 Project Managers and 4 Implementation Engineers. Run 1:1s and team meetings. Coach both technical and non-technical team members. Set a high bar and help people grow.

What success looks like

• Identification and remedy of delivery bottlenecks
• Stronger retention and adoption driven by better implementations
• High customer sentiment during and after onboarding
• Faster time to value for new customers

Who you are

• You’ve led a Professional Services or Implementation team at a SaaS company.
• You’re comfortable managing implementation engineers and project managers.
• You’ve directly led $50k-$200k implementation projects.
• You’ve worked on integrations where APIs had to be designed and built, not just consumed.
• You communicate clearly, bring structure to ambiguity, and make sound decisions without perfect information.
• You want to be in the office and work closely with your team.

About Proton.ai

Distribution is an $8 trillion industry that technology forgot. 75,000+ distributors globally. Half of their sales reps still don't use a CRM. The ones that do are stuck with generic tools built for tech companies—not businesses managing millions of SKUs and thousands of customer relationships.

We're building the industry cloud for distribution—and every product is AI-native from the ground up. We started with AI-powered CRM. Now we're expanding: our second product is live and growing fast, another product launches in March, with more on the roadmap. We're not bolting AI onto legacy software. We're rebuilding the entire stack with AI at the core. Our vision is to become the operating system for how distributors run their business.

This is a rare opportunity: a massive underserved market, strong product-market fit (120%+ NDR, 93% logo retention), and we're just getting started on the multi-product journey.

$20M Series A from Felicis (Canva, Notion, Shopify) and Battery Ventures.

Team of 70. Cambridge HQ. We’re all in the office Mondays, Wednesdays, and Thursdays. 

Benefits

• Competitive salary and stock options—we want you to feel like an owner
• Unlimited PTO + 10 company holidays
• 401k with 3% company contribution (regardless of whether you contribute)
• Medical, dental, and vision insurance (options with 100% employer-paid premiums)
• 12 weeks fully paid parental leave
• Annual company-paid offsites
• Professional Growth Fund for learning opportunities

The Opportunity

Proton is building the industry cloud for distribution—an $8 trillion market that technology forgot.

Our first product is an AI-powered CRM built specifically for distributors—it helps their sales teams know which customers to call, what to sell them, and when. We're at ~$10M ARR with 120%+ NDR. Our second product, PIM (Product Information Management), helps distributors manage their product catalogs—think millions of SKUs with specs, images, and pricing that need to stay accurate across systems. PIM is growing fast. Another product launches in March, with more on the roadmap.

We're looking for a Senior Financial Analyst to be our finance lead. You'll own the function—building our operating model, running FP&A, managing reporting and compliance, and working directly with the CEO on financial decisions. You'll have one direct report (our bookkeeper) and full ownership of how finance runs at Proton.

If you succeed, you'll have built the finance infrastructure that supports Proton's growth from $10M to $50M+ ARR. 

We are looking to hire someone in the greater Boston area who is open to a hybrid schedule (3 days in office, Havard square). The target salary range for this role is $140,000- $170,000. Final offers will be based on your skills and previous experience.

Partner with the CEO (20%)

• Startup experience. You've worked at a Series A or B stage company and understand the pace and ambiguity.
• Based in Boston. In office 3x/week in Kendall Square.
• Exceptional attention to detail. Your models are airtight. Your reports are accurate. You catch things others miss.

What Sets You Apart:

• You're reliable. When you say something will be done, it gets done—on time and correctly.
• You're curious. You dig into the numbers to understand what's really happening in the business.
• You communicate clearly. You can explain financial concepts to non-finance people and help them make better decisions.
