Copywriter, Performance Marketing

Xometry (NASDAQ: XMTR) powers the industries of today and tomorrow by connecting the people with big ideas to the manufacturers who can bring them to life. Xometry’s digital marketplace gives manufacturers the critical resources they need to grow their business while also making it easy for buyers at Fortune 1000 companies to tap into global manufacturing capacity.

Xometry is seeking a Performance Marketing Copywriter to own the copy that carries a prospect from click to conversion — marketing and lifecycle emails, video/explainer scripts, and the landing pages that sit at the end of the funnel, across both the Xometry and Thomas brands.

Write video scripts for YouTube, paid social, and product explainer videos, translating technical capabilities into clear, credible narratives

Write landing page copy that converts, from hero messaging and value props through to CTAs, aligned with the traffic source and offer

Partner with Lifecycle Marketing to plan and sequence email journeys, and with designers/video producers to align copy with visuals and pacing

Collaborate cross-functionally with Product, Content, and Growth Marketing to keep messaging aligned with campaign goals and brand voice

Use performance data (open rate, CTR, CVR, watch-through rate) and testing insights to refine copy for higher engagement and conversion

Contribute to campaign brainstorms and messaging strategy with a creative, test-and-learn mindset

Maintain and evolve messaging frameworks, email templates, and landing page copy blocks for reuse across campaigns

Build and use Claude Skills to speed up copy production, QA, and A/B test variant generation

Maintain a deep understanding of target audiences across both the Xometry and Thomas platforms
