Responsibilities

Join us and make an impact!
3E is seeking a Senior Portfolio Growth Marketing Manager to help shape the growth of our Chemical & Workplace Safety portfolio, our largest business line, and take ownership of marketing for some of the highest-growth opportunities across our portfolio.
This is a hands-on portfolio marketing role for someone who can turn market, customer, and product insights into action. You’ll develop positioning and messaging, build integrated campaigns, optimize digital experiences, enable our commercial teams, and use performance data to continually improve what we do.
You’ll work at the intersection of Product, Sales, GTM, Regional Marketing, and the broader Marketing organization, helping connect our solutions to the industries, buyers, and business challenges they serve. With colleagues across regions, you’ll have the opportunity to influence how we take our portfolio to market globally.
The environment moves quickly. Products evolve, priorities shift, and marketing needs to keep pace. You’ll need to be comfortable making informed decisions, iterating quickly, and moving work forward without waiting for every detail to be finalized.
AI is also embedded in how this team works. We’re looking for someone who already uses AI as a strategic collaborator, not simply to generate content, but to test messaging and personas, explore campaign angles, challenge assumptions, identify gaps, synthesize information, and work more effectively.
If you enjoy combining strategic thinking with hands-on marketing execution, experimenting with new approaches, and turning ideas into measurable commercial impact, this role offers the opportunity to do all three.
Location: This position supports remote work within the Eastern time zone.
Develop and own portfolio marketing plans that generate and accelerate pipeline, support new customer acquisition and cross-sell, strengthen retention and account growth, and build 3E’s presence within priority industries and target accounts.
Create and continually refine buyer- and industry-specific positioning, messaging, and value propositions for our Chemical & Workplace Safety portfolio.
Translate product capabilities, buyer needs, industry trends, and customer challenges into compelling solution narratives and integrated marketing strategies.
Partner with Demand Generation, Regional Marketing, Events, Brand, Content, and other marketing teams to build, execute, and optimize integrated campaigns across digital advertising, email, social media, events, content, and other relevant channels.
