About LightSource
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.
About the Role
We're looking for a Senior Product Marketing Manager — someone who can own how LightSource is understood in market and help build the PMM function from the ground up. This isn't a typical PMM role. You won't inherit someone else's positioning — you'll sharpen and own it. You'll work closely with product, sales, and leadership to craft messaging that lands with procurement and operations leaders, and produce the content that puts those ideas in front of the right people.
The right person will combine strategic depth with a writer's instincts and a builder's work ethic. You know how to market technical products to skeptical industrial buyers — and you've found a way to do it credibly. You will be the person who defines how LightSource is talked about, sold, and remembered.
Role & Responsibilities
Own and continuously refine LightSource's positioning, messaging architecture, and ICP definition
Develop buyer personas grounded in real customer and prospect research, win/loss interviews, sales call analysis, and market study
Drive product launches end to end: messaging, internal enablement, external assets, and coordinated rollout with sales and demand gen
Build and maintain a core sales enablement library: one-pagers, battlecards, objection handling guides, and ROI frameworks
Own the content strategy and editorial calendar — set priorities, write or commission key pieces, and maintain quality across all formats
Write thought leadership content (long-form, point of view, research-backed) that builds LightSource's credibility in supply chain and procurement circles
Partner with demand gen on campaign messaging, AEO visibility, and analyst and press narratives
Track competitive positioning and maintain clear, current battlecards
Help hire and mentor future PMM and content hires as the team grows
About You
You're not looking to maintain a positioning doc someone else wrote — you want to own the narrative. You've done this for a technical product with a complex buying process and you know how to bring rigor and creativity to both. You're a strong writer who doesn't lose precision when translating capability into value. You thrive in environments where strategic thinking and getting your hands dirty are equally expected. You might be a great fit if you:
Have 5–8 years in product marketing or content marketing at a B2B SaaS company
Are a strong writer who can translate technical capabilities into business value without losing precision or credibility
Have a track record of conducting and applying buyer research to improve messaging and win rates
Have experience supporting enterprise or mid-market sales cycles with high-quality enablement materials
Are comfortable leading cross-functional workstreams — you know how to align product, sales, and marketing without owning everything
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
Comp & Benefits
Top-of-market base compensation with meaningful early-employee equity
Platinum-level healthcare, 100% covered for employees
Dental and vision, 100% covered
401(k) program
Unlimited vacation and sick days
Free food (3 meals a day, if desired) in office locations
Frequent team offsites, events, dinners, and weekend trips
Bonus Points
Located in (or willing to relocate to) San Francisco, Boulder/Denver, or Seattle
Background in or deep familiarity with supply chain, procurement, or industrial operations
Experience marketing AI or data intelligence products to non-technical buyers
Analyst relations or media experience
You can code in Rust (kidding... unless?)

Step 2
Worth raising before applying or in the first recruiter conversation.
01How is success measured for this role?
Why ask this: Useful when the posting doesn't name success metrics. Triggered by the posting’s mention of baseline (always asked when metrics are missing).
02Which channels own the largest part of the growth or pipeline target today?
Why ask this: Triggered when paid search or paid social signals appear in the posting. Triggered by the posting’s mention of paid acquisition / demand gen signals.
03Which systems and attribution models are considered the source of truth?
Why ask this: Triggered when marketing ops, attribution, or analytics tooling is named. Triggered by the posting’s mention of marketing ops / analytics tooling.
04How is the ICP / persona work structured between product marketing and sales?
Why ask this: Triggered when product marketing or sales enablement signals appear. Triggered by the posting’s mention of product marketing / enablement signals.
Step 3
Each angle below starts from a real signal in the posting. The phrase “if this reflects your real experience” matters — don’t invent experience you don’t have.
Angle 01
SEO / organic angle
If this reflects your real background, emphasize: technical SEO and content production, organic traffic and pipeline contribution, and tools (Search Console, Ahrefs, Semrush)
Why we suggest this: posting mentions seo / content.
Keyword stuffing, fabricated bullets, or borrowed metrics tend to backfire in the first screen. Use these as a checklist, not a script.
