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
