About The Position

LightSource is building the next-generation operating system for Procurement. Sales has Salesforce. HR has Workday. Procurement is next. We build SaaS software that helps procurement leaders discover vendors, manage negotiations, and buy intelligently. Our team is small but growing quickly, backed by top-tier investors and already winning enterprise customers. We're tackling a massive market filled with complex, high-impact problems. The team includes people who've helped build companies like Tesla, Waymo, McKinsey, and Google X. We hire exceptional people, move quickly, give direct feedback, expect excellence, and have a lot of fun doing it. We're looking for a Marketing Generalist — someone who wants to be in the middle of everything and help build the marketing function from the ground up. This isn't a narrow, stay-in-your-lane role. You'll support demand gen campaigns, produce content, coordinate events, and do the connective tissue work that makes a small marketing team punch above its weight. The right person is sharp, organized, and genuinely curious about AI and industrial tech. You're not a specialist yet — and that's fine. What matters is that you deliver quality work across a range of formats without much hand-holding, and that you're excited to learn fast in an environment where the scope is wide and the feedback loop is short.

Requirements

2–4 years of marketing experience, ideally in a B2B environment — startup experience essential
Organized and dependable: you manage your own workload, hit deadlines, and communicate proactively when things shift
A clear, concise writer who can adapt tone to format without losing clarity
Comfortable in HubSpot or similar CRMs — you've used them to run campaigns or manage contacts, not just look things up
Genuinely curious about AI, supply chain, or industrial technology
Team-oriented and low-ego: you're happy doing the work that makes others more effective
Value direct feedback and continuous improvement

Nice To Haves

Located in (or willing to relocate to) San Francisco, Boulder/Denver, or Seattle
Experience with tools like Canva, Notion, or Figma for lightweight asset production
Exposure to ABM or field marketing programs
Prior experience at an early-stage or Series A startup
You can code in Rust (kidding... unless?)

Responsibilities

Support campaign execution across channels — help build assets, coordinate approvals, and monitor performance
Own social media presence (LinkedIn primarily), including scheduling, community management, and lightweight content production
Coordinate logistics for field events, trade shows, and webinars: vendor management, collateral, registration, and follow-up
Draft, edit, and format content across formats: emails, blog posts, one-pagers, and social copy
Manage HubSpot list hygiene, campaign setup, and basic reporting so the team has clean data to work from
Maintain the marketing asset library and keep internal wikis and templates current
Handle vendor and agency coordination, track invoices and deliverables, and flag issues early
Take on ad hoc projects across demand gen, PMM, and ops as priorities shift
