ABOUT THE ROLE

Lunar is hiring a Senior UX/UI Designer to help lead website and landing page design across our Shopify client roster. You'll own projects end to end: strategy, wireframes, high-fidelity UI, interactive prototypes and dev handoff.

Design at Lunar sits at the center of three areas of work:

  • Onsite design: full-site redesigns, homepages, PDPs, PLPs and carts for DTC brands on Shopify.
  • Landing pages: paid media landing pages and post-click funnels built in our no-code page builder.
  • CRO test design: A/B test variants and experiments, built from hypotheses with our CRO lead and shipped on a steady testing cadence.

This is a hands-on senior role with a strong CRO lens. You'll work closely with our CRO lead, turning test hypotheses into designs and test results into better-converting experiences.

You'll partner with strategy, paid media, creative, development and project management to tie every design decision to client growth goals.

WHAT YOU'LL OWN.

  • Site design: Lead UX/UI for full-site redesigns, homepages, PDPs, PLPs and carts, from discovery and IA through final UI.
  • Landing pages: Design landing pages and post-click funnels for paid traffic, from ad click to checkout.
  • CRO partnership: Partner with the CRO lead on site audits, hypotheses and test roadmaps. Design A/B test variants and help analyze results.
  • Prototyping and handoff: Build interactive prototypes in Figma or HTML/CSS that double as client presentations and developer handoff.
  • Shopify execution: Design responsive, mobile-first experiences that hold up in real builds, including sections, blocks, apps and theme constraints.
  • Design systems: Contribute to component libraries and page-builder section systems used across clients.
  • Content hierarchy: Shape page narrative and provide general copy direction for headlines, offers and buy box messaging.
  • Client presentation: Present concepts, share rationale behind design decisions, and fold in feedback without losing the lens of best practices.
  • Dev collaboration: Work with developers on feasibility, handoff, and QA.
  • Process: Improve design SOPs, file organization and workflows, including AI-assisted design and prototyping.

REQUIREMENTS

  • 5+ years of UX/UI design experience, focused on ecommerce websites and landing pages
  • Hands-on CRO experience: you've designed tests, read the results and can point to conversion impact
  • Shopify knowledge, including themes, sections, metafields/objects, common apps and how designs get built
  • Advanced Figma skills: auto layout, variants, components, tokens and prototyping
  • Agency or multi-client experience
  • A portfolio showing process and shipped ecommerce work, ideally with results
  • DTC or CPG brand experience (supplements, beverage, beauty, wellness) preferred
  • Working knowledge of HTML, CSS and JavaScript preferred
  • Familiarity with GA4, heatmaps, session recordings and A/B testing tools such as Intelligems, Hotjar or Microsoft Clarity
  • Experience with landing page builders and direct-response page structure
  • AI proficiency a plus: experience using AI tools for design, prototyping or front-end code (e.g. Claude, Codex, Figma AI)

WHO YOU ARE

  • A designer who measures good design by how it performs
  • Opinionated, and able to defend a point of view with rationale and data
  • Comfortable presenting to clients and senior stakeholders
  • Fast, organized and able to run several projects at once
  • Detail-obsessed through QA and launch
  • A clear communicator with developers, strategists and copywriters
  • Generous with feedback and interested in mentoring other designers
  • Curious about new tools and quick to put them to work

TOP REASONS YOU’LL LOVE IT HERE:

  • Accelerated career growth and leadership opportunities.
  • Direct mentorship and collaboration with senior leaders across departments.
  • A talented, supportive, and passionate team that loves what we do.
  • Competitive benefits including 100% paid Medical, Dental, Vision, STD, LTD, and Life insurance.
  • 401K with company match.
  • Generous PTO and holidays, plus a day off during your birthday week!
