    Description

    Hybrid Product Marketing & Content Marketing Manager


    Who We Are


    LightSource is the next-generation operating system for procurement. We build SaaS software for procurement leaders—the people responsible for managing suppliers and vendors.

    Sales has Salesforce. HR has Workday. And now, finally, procurement has LightSource.

    Think of us like a CRM, but instead of helping sales professionals find customers, we help procurement managers find vendors, manage negotiations, and buy intelligently.

    Our team is small but growing quickly. We're (exceedingly) well-funded by top-tier investors and already punching well above our weight-class with enterprise logos—despite having no dedicated sales professionals on our team to date.

    The Team


    We're a driven, high-caliber team who've helped build some of the world's most innovative companies (Tesla, Waymo, McKinsey, and Google X). Now we're tackling one of the biggest and thorniest problems in enterprise.

    Our team is small, but our ambitions are big. We only hire the best and are obsessed with learning every day—while having a lot of fun along the way.

    You'll report directly to the Head of Marketing and work closely with leaders across Product, Sales, and Customer Success.

    About You

    • Skilled at translating product roadmaps into compelling narratives, campaigns, and GTM strategies

    • Adept at supporting new feature launches and customer-facing enablement

    • Experienced in creating high-impact content (whitepapers, exec briefs, videos) for enterprise buyers

    • Comfortable conducting persona interviews, win/loss analysis, and competitive research

    • Strong collaborator who can align cross-functionally with Product, Sales, and Customer Success

    • Analytical mindset with the ability to assess performance and iterate on content and GTM initiatives

    • Able to work with analysts and industry stakeholders to elevate visibility

    Role and Responsibilities


    We're seeking a strategic Product Marketing Manager (PMM) with strong Content Marketing (CM) expertise to drive go-to-market initiatives for our enterprise B2B SaaS platform.

    This is a hybrid role weighted 70% toward Product Marketing and 30% toward Content Marketing, focused on targeting key procurement and supply chain leadership personas at large enterprises—CPOs, VPs of Procurement, CSOs, and Digital Transformation leaders.

    You'll partner cross-functionally across Product, Sales, Success, and Marketing, shaping how we position our offerings, generate pipeline, and build lasting thought leadership in our market.

    What You'll Do


    Product Marketing (70%)

    • Craft compelling narratives and differentiated value props for enterprise audiences

    • Build messaging frameworks, battlecards, and positioning materials

    • Own GTM planning for new features and launches

    • Create sales enablement assets (decks, objection handlers, customer stories)

    • Conduct persona research, competitive analysis, and win/loss interviews

    • Bridge Product, Marketing, and Sales with consistent messaging and enablement

    • Support analyst relations through submissions, surveys, and briefings

    Content Marketing (30%)

    • Drive a content calendar aligned to enterprise personas and funnel stages

    • Oversee creation of blogs, whitepapers, videos, case studies, and infographics

    • Optimize assets for SEO, UX, and conversion

    • Partner with SMEs and external vendors to scale content production

    • Distribute content across owned, earned, and paid channels

    • Produce thought leadership aligned to industry trends and buyer pain points

    You've Got the Goods If You've Delivered On…

    • Increasing qualified pipeline and sales enablement engagement

    • Driving growth in content engagement and share of voice

    • Accelerating product adoption post-launch

    • Shortening sales cycles with persona-aligned messaging

    • Building strong analyst and influencer presence in-market

    Qualifications


    Must-Haves

    • 5+ years in B2B SaaS product marketing, with an enterprise customer focus

    • 2+ years leading or supporting content marketing strategy

    • Proven success targeting technical and skeptical enterprise buyers (CFO, CTO, CPO, CSO)

    • Portfolio of content and enablement work

    • Strong cross-functional collaboration and communication skills

    • Comfortable with Notion, Google Workspace, CMS platforms (Webflow/WordPress), SEO tools (Ahrefs/Moz)

    • Bachelor's degree required (MBA a plus)

    Nice-to-Haves

    • Experience in procurement, finance, or supply chain SaaS

    • Familiarity with Hubspot, Gong, Outreach, Salesloft

    • Exposure to GenAI tools like ChatGPT, Perplexity, Gemini, Gamma, Manus

    Why This Role Is Exciting


    You'll shape the narrative and GTM execution of a fast-scaling SaaS platform transforming enterprise procurement and supply chains. From crafting thought leadership to enabling sales, your work will directly influence how Fortune 1000 companies discover, evaluate, and adopt our solutions.

    Bonus Points

    • Based in (or open to relocating to) San Francisco, CA.
