Job description

• Write short-form, conversion-focused copy across direct mailers, email, text, display ads, outbound calling scripts, and digital surfaces (landing pages, app, portal).
• Design and run structured A/B and multivariate tests on messaging, offers, and creative, with a clear hypothesis and defined metric for every test.
• Build and maintain agentic workflows using insights-driven value proposition messaging to produce and personalize campaign copy at scale, with a human checkpoint.
• Partner with Product, Analytics, and Member Experience to turn proven copy patterns into repeatable, configurable templates.
• Use performance data and member feedback loops to retire ineffective approaches and scale successful ones.
• Monitor campaign performance dashboards and channel-level conversion metrics to determine what gets tested next.
• Maintain shared style, voice, and compliance checklists so AI-generated variants remain on-brand and audit-ready.

• Direct experience designing and reading A/B or multivariate tests, including ones that lost, and the ability to explain what you did with the result.
• Hands-on experience using AI tools to build a repeatable production or QA workflow, not just to draft copy faster.
• Comfort working from data and being wrong in public - you'd rather ship a testable hypothesis than defend a favorite line.

• Nice to have: familiarity with Salesforce Marketing Cloud or comparable ESPs/CDPs.
• Nice to have: experience writing for contact-center scripts.
• Experience writing short-form, conversion-focused copy rather than long-form articles, blog posts, or internal communications.
