Your impact

We're looking for an AI-native Performance Marketing Lead to own paid acquisition across three lanes: filling and optimizing our self-serve funnel, running ABM and retargeting across social, and building awareness in a category where competitors have a much larger share of voice.

This role spans paid search and paid social (LinkedIn, Meta, X, Reddit). You’ll work closely with the VP of Marketing, GTM engineering, and sales. It's a hands-on role: you'll build the campaign, write the copy, ship the landing page, and report on the data yourself.

What you'll do

Fill and optimize the self-serve funnel as a feeder for sales

• Own paid search as the primary acquisition engine for self-serve signups - keyword strategy, competitor capture, landing page testing, and continuous efficiency work against high-intent developer queries

• Optimize the full path from click through signup and activation, treating first successful API call and early usage as the qualification signal that routes an account to sales

• Partner with sales to define what makes a self-serve signup worth a conversation, and tune acquisition toward accounts that meet that bar rather than raw volume

• Build the reporting that follows a click through signup, activation, sales handoff, and closed revenue

Run ABM and retargeting programs across social

• Execute account-based campaigns on LinkedIn, Meta, and X against target account lists sourced from GTM engineering - you'll partner with them on what you need and how it's segmented

• Produce the creative these campaigns run on - write the copy and build lightweight assets yourself where you can, and scope, brief, and manage freelancers or agency partners where you can't

• Design multi-touch retargeting sequences that keep us in front of accounts already in the funnel, coordinated with sales outreach rather than running parallel to it

• Measure and report account engagement and pipeline influence using multi-touch attribution tools

Build brand awareness through display and upper-funnel media

• Run display and awareness campaigns that build recognition with developers and founders before they start actively evaluating

• Extend reach through developer-native placements - newsletters, podcasts, technical publications, and community sponsorships

• Develop upper-funnel creative and messaging in partnership with product marketing, and sustain enough variant volume that performance doesn't decay

• Establish sensible measurement for brand work - reach, share of voice, branded search lift, and self-serve signup trends

What you'll bring

• 3–5 years hands-on in performance marketing, with demonstrated depth in both paid search and paid social

• Experience marketing to a developer audience in prior roles

• Experience marketing a self-serve product that feeds a sales motion

• Prior hands-on experience with X and Google DV360 are a plus

• Power user of Claude Code or equivalent, thinking in terms of agents and systems

• We're deliberately open on background. Three paths we'd be glad to see:

  • Agency - you've run search and social across many accounts and budgets, you move fast, and you've seen more experiments than any single in-house role would give you

  • CPG or consumer brand - you understand creative velocity, audience testing, and how to build awareness for something people aren't yet searching for

  • B2B SaaS - you know ABM, LinkedIn targeting, and how marketing spend ladders up to a pipeline number sales will actually accept

Candidates must be based in the SF Bay Area or willing to relocate (you will be working on-site in our South Bay office a few days a week).

The base salary range for this full-time position is $140,000 - $190,000+ bonus + equity + benefits.
