Sr. Content Marketing Manager

Proton.ai • Cambridge, MA

7h

About The Position

Proton is building the AI infrastructure for wholesale distribution, embedded in the workflows that move nearly every physical product on the planet. Distribution is a $9 trillion industry, and the software that has been stuck in the past for decades — most tools create more work than they eliminate. We unify CRM, PIM, eCommerce AI, and Order & Quote Entry AI into one platform with one data layer and one AI brain, so reps spend their time deepening customer relationships, not entering data.
We hire people with high agency and high urgency. At Proton, everyone is a builder who owns problems end to end and ships AI-native software faster than anyone else in the category.
The median Proton customer reports 3x profit return per dollar spent, an extra day of sales per rep per month, and “the best ROI of any tech investment in 30 years.” Hundreds of leading distributors — from family-owned shops to publicly-traded enterprises across industrial, HVAC, and electrical — run on Proton. We’re backed by Felicis Ventures (Twitch, Shopify, Opendoor) and Battery Ventures.
If you want to build the brand and the content engine that shape how trillions of dollars of physical goods move through the economy, Proton is the place to do it.

The role
Content is how Proton earns the trust of an industry that doesn’t buy software from people it doesn’t already respect. At any given moment, only 5% of distributors are in-market for a CRM — our job is to be the obvious choice for the other 95% when their moment comes. The Senior Content Marketing Manager owns that job.
This is a senior IC role. You’ll own our content strategy, write the work, run the podcast, ship the case studies, build the AI workflows that make all of it scalable, and partner closely with Benj (our CEO) to make him the most recognized voice in distribution. You’ll work alongside our events lead, BDR, and CX team — but content is yours, end-to-end. Today, much of this work runs through Katie and a content agency. You’ll absorb that scope, exceed it, and go far beyond — into AI-native production, SEO/AEO, and a real editorial point of view that compounds quarter over quarter.
Events are owned by a separate role — you can focus on content.

Requirements

• You’ve built (not just managed) a content function — calendar, voice, AI workflows, distribution playbook, measurement
• You can write in someone else’s voice better than they can. You’ve ghostwritten for a founder or CEO and have the receipts
• You have a deep passion for AI: you keep up with the latest releases, experiment constantly, have fully integrated AI into your workflows, and have strong opinions about which model writes which voice best
• You have production experience with Claude or comparable models (custom projects, prompt chains, transcript pipelines, brand-voice editing, AEO research)
• You can hold your own in a room with executives — interviewing a CEO on a podcast, pushing back on Benj’s first take, pulling the angle out of a 60-minute customer call
• You’re curious about wholesale distribution — or at least curious enough to be fascinated within a week
• You measure content the way Sales measures pipeline: outcomes, not impressions
• You bias toward ownership, urgency, and shipping in ambiguity

Nice To Haves

• If AI and modern content workflows are something you’ve been meaning to get around to, we’re not the place to figure it out. You should be experimenting already.
• Wholesale distribution is the audience. If “HVAC parts and electrical supply” makes you tune out, this isn’t your role.

Responsibilities

• Own the content strategy end-to-end: editorial calendar, channels, voice, distribution, measurement. Decide what we ship, what we kill, and what we double down on
• Ghostwrite thought leadership for executime team: long-form articles, LinkedIn posts, op-eds in trade publications (Distribution Strategy Group, MDM, IndustryWeek), keynote outlines. His voice, your craft
• Run the Proton podcast: guest research and booking, interview prep, post-production coordination, show notes, blog adaptations, social cutdowns, and the BDR follow-up motion that turns episodes into pipeline
• Partner with CX to turn every customer win into a multi-format asset — case study, blog, LinkedIn carousel, podcast clip, sales one-pager — within 30 days of close
• Own SEO/AEO strategy: rank for the queries our buyers ask Google, and become the cited answer when they ask Claude or ChatGPT. Coordinate with Engineering and our content agency on execution
• Build the AI content stack: Claude projects trained on our voice, transcript-to-outline pipelines, brand-voice editing prompts, automated repurposing workflows, AEO research agents. Ship it, document it, share it
• Run the monthly nurture newsletter: write it, design it, segment it, and measure what it does for pipeline
• Drive our LinkedIn presence: 4–5 posts a week, comment strategy, and a system that turns every customer call, podcast, and internal Slack take into content
• Produce demo-on-demand and product narrative content alongside Product and Demand Gen: scripts, talking-head videos, walkthroughs that convert browsers into demos
• Instrument content performance: pipeline influenced, opportunities sourced, AEO citations, BDR follow-up volume. Kill what isn’t working
• Stay on the cutting edge of AI for content: new models, prompt techniques, voice cloning ethics, AEO, generative search. Bring what you learn into production fast

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
