LightSource is building a next-generation operating system for Procurement—SaaS software that helps procurement leaders discover vendors, manage negotiations, and buy intelligently. The company is backed by top-tier investors, already winning enterprise customers, and has a team that includes alumni from Tesla, Waymo, McKinsey, and Google X.
You will be LightSource's first Growth & Demand Generation Manager, tasked with building the marketing function from the ground up. This is not a role where you execute someone else's playbook; you will help write it. You'll work closely with leadership and Account Executives to design the inbound and outbound marketing motions that fuel the next phase of growth.
Key responsibilities include:
- Build the demand generation playbook from scratch, including AEO, paid campaigns, lifecycle campaigns, ABM programs, and the attribution stack
- Own top-of-funnel pipeline generation and be directly accountable for MQLs and sourced pipeline
- Partner closely with sales to define ICP tiers, score inbound leads, and design tight MQL-to-SQL handoffs
- Build and run account-based marketing campaigns targeting key verticals: manufacturing, industrials, and supply chain-heavy sectors
- Manage and optimize budget allocation across channels, continuously testing and cutting underperformers
- Own HubSpot workflows, landing pages, and campaign operations end to end
- Coordinate with content and product marketing to ensure campaigns are backed by strong messaging and relevant assets
- Help hire and mentor future marketing hires as the team grows
You are someone who wants to build, not maintain. You've been a top performer and are seeking more ownership. You enjoy constructing demand engines from scratch and thrive in environments where initiative matters more than process. You're disciplined with metrics but lead with creativity.
Requirements:
- 5+ years of experience in demand generation or growth marketing, ideally at a B2B SaaS or data-driven company
- Track record of running paid campaigns on LinkedIn and Google, including budget management and optimization
- Comfortable with HubSpot—you know how to build workflows, not just use templates
- Strong analytical instincts: you track CAC, MQL volume, and pipeline sourced, and can diagnose why numbers move
- Ability to write clear, direct copy when needed and brief agencies or contractors effectively
- Thrive in fast-moving startup environments with high autonomy and high expectations
- Want to grow into leadership and help build a team over time
- Value direct feedback and continuous improvement
Bonus qualifications:
- Prior experience in industrial tech, supply chain, or manufacturing SaaS
- Familiarity with ABM tools (6sense, Demandbase, or similar) and intent data platforms
- Experience building first-party audience strategies
