Job Description

Sustainment is an AI-native software platform that helps US-based manufacturers easily find and work with the critical suppliers they need to build and manage their supply chains. Our vision is to reimagine American manufacturing as a hyperconnected, secure, and resilient ecosystem of local and regional suppliers who can more easily connect, interact, and do business with the industry and government customers that rely on them. We are a dual-use technology platform that supports both DoD and commercial customers in pursuit of our vision.

We’re looking for a curious, driven Marketing Manager who loves to communicate, create, and experiment, and who is excited to grow alongside a fast-moving B2B SaaS startup. This role is ideal for someone who has taken strong early steps in their marketing career, enjoys wearing multiple hats, and thrives in a dynamic, collaborative environment where ideas quickly turn into action.

The Marketing Manager will be responsible for planning and executing content-led initiatives, including lead magnets, sales enablement, blog content, and newsletters. These content forms should attract, educate, and convert prospects into qualified leads for our GTM team. Success in this role looks like driving pipeline growth, improved website conversion rates, and increased engagement with new content forms that support customer acquisition targets.

This is a high-impact opportunity for a marketer who wants real ownership, close partnership with Product, Sales, Marketing Leadership, and RevOps, and the chance to see their work directly influence company growth. If you are energized by learning quickly, trying new things, and helping build fast, this role offers significant room for both personal and professional growth.

What you’ll bring:

• 3+ years of experience in B2B/SaaS marketing, with a strong emphasis on inbound, content, and demand generation
• Excellent written and verbal communication skills, with the ability to create clear, compelling messaging for technical and non-technical audiences
• Proven success using content-first strategies (e.g., lead magnets, newsletters, product content, sales enablement assets, website conversion paths) to drive qualified inbound leads and pipeline
• Strong understanding of B2B buyer journeys and how content supports awareness, consideration, and conversion
• Ability to create high-quality sales enablement content that supports new customer acquisition and deal progression (e.g., one-pagers, decks, case studies, battlecards, testimonials)
• Hands-on ownership of content distribution and social channels, including publishing, performance analysis, and follower growth across platforms such as LinkedIn, X, YouTube, and other major channels
• Proficiency with HubSpot (or similar marketing automation/CRM tools) for campaign execution, reporting, and lifecycle management
• Hands-on experience managing and updating websites using a CMS (e.g., Webflow, WordPress, or similar)
• A data-driven, analytical mindset with the ability to measure performance, interpret data, and iterate quickly
• Comfortable thriving in ambiguous, fast-paced environments where priorities shift and scrappy execution is required
• Background working in early-stage or high-growth SaaS companies
• Familiarity with or strong understanding of manufacturing, industrial, or supply chain audiences is a plus
• Experience with newsletter programs and audience engagement initiatives (e.g., Beehiiv or similar tools) is a plus
• Bachelor’s degree or equivalent work experience

How you will lead:

• Own and execute content-first inbound marketing initiatives that drive awareness, engagement, and qualified pipeline across key buyer segments
• Develop, launch, and optimize content programs including lead magnets, newsletters, product content, sales enablement assets, case studies, and landing pages aligned to B2B buyer journeys
• Create and maintain sales enablement content in close partnership with Sales and Product to support prospect education, objection handling, and deal progression
• Manage and continuously improve the company website and conversion paths, ensuring content, messaging, and UX support inbound lead generation goals
• Partner closely with Product, Sales, Marketing Leadership, and RevOps to align content, messaging, and campaigns with go-to-market priorities and pipeline needs
• Use HubSpot to manage campaigns, lifecycle stages, reporting, and attribution, translating performance data into actionable improvements
• Test, measure, and iterate on inbound programs with a data-driven, experiment-first mindset
• Support industry events, conferences, and field marketing efforts, including planning, content development, on-site execution, and post-event follow-up
• Contribute wherever marketing impact is needed, wearing multiple hats and adapting quickly as priorities shift in a high-growth environment
• Share insights on content performance, buyer behavior, and market trends to inform broader marketing and GTM strategy
• Travel as needed (up to ~20%) to support events, cross-functional initiatives, and key marketing moments
