Performance Marketing Engineer

Moritz is an AI-native legal services company (backed by YC, 20VC and +20 unicorn founders) building the layer between Big Law and pure AI tools.

We're hiring a Performance Marketing Engineer in San Francisco to own paid acquisition end-to-end and build an AI-native growth engine that fuels our enterprise pipeline.

Success in this role means defensible CAC, a steady flow of qualified pipeline for the GTM team, and a paid program where AI is wired into every layer - creative, targeting, analysis, and reporting. You'll report to the CEO and work closely with GTM and the founding team.

Responsibilities

• Own strategy, execution, and budget for all paid channels (LinkedIn, Google, and emerging B2B surfaces)
• Build internal tooling, scripts, and AI agents to automate campaign ops, reporting, and creative iteration
• Use LLMs and generative tools to produce, test, and refine ad creative and landing pages at high velocity
• Build and maintain attribution and reporting infrastructure to measure pipeline impact end-to-end
• Run a continuous, AI-assisted testing roadmap across creative, audiences, landing pages, and offers
• Partner with GTM to align campaigns with target accounts and pipeline goals
• Forecast spend, model CAC and payback, and report performance to the founding team weekly

Qualifications

• 3–5 years in performance marketing, with experience at an early-stage startup and/or an established firm
• Proven track record driving B2B growth — measured in pipeline and revenue, not impressions
• AI-native operating skills
• Deep fluency in LinkedIn Ads and Google Ads; experience with multi-touch attribution tools
• Exceptionally analytical; can defend every dollar of spend with data
• Self-directed operator who can go from strategy to execution without handoffs
