The Opportunity

We're looking for a UX Design Engineer to own and perfect the end-to-end user experience. The ideal person for this role obsesses over the details and can deliver improvements to the product.

Most engineering teams treat UX refinement as an afterthought squeezed between feature work. We have a dedicated role for it because we believe the difference between "works" and "delightful" is what separates good products from great ones. You'll have the space to really care about craft. We're a technical team building for technical users. Your job is to make the experience of using our product enjoyable!

What You'll Do:

Own the "look and experience" of the product end to end:

User Research

• Identify pain points
• Watch real users in Fullstory, identify friction points, and fix them

Design Solutions

• Prototype interaction alternatives rapidly (in Figma or code) to test different approaches
• Create, refine, and iterate on UX flows and interaction patterns

Implement Solutions

• Work closely with our Senior engineers who own feature architecture - they build the foundation, you perfect the interface
• Run lightweight usability tests to validate improvements
• Build reusable interaction patterns that the team can leverage

A typical week might include:

• Watching 10 user sessions, identifying common friction points
• Meeting with users to get deeper on new product features feedback
• Prototyping different flows in Figma
• Implementing design improvements with smooth transitions and helpful inline guidance
• Pairing with Staff engineers to refactor a complex form into a multi-step wizard
• Running a quick usability test with 5 users on the new onboarding flow

You're a great fit if:

• You have an engineering background - you’ve either been an frontend developer, have an engineering degree, or you have used Claude Code/Cursor to make impactful design changes.
• You've worked on complex tools (dev tools, data tools, B2B SaaS) where UX really matters
• You've made products noticeably better through refinement (show us!)
• You’ve built or contributed to design systems and animation libraries.
• You've used feedback collection tools and incorporated user feedback into designs
• You can work in Figma to wireframe and create flows to share with fellow engineers
• You think about edge cases, loading states, and empty states automatically

The estimated annual salary for this role is between $165,000 - $200,000, plus a competitive equity package. Actual compensation is determined based upon a variety of job related factors that may include: transferable work experience, skill sets, and qualifications. Total compensation also includes a comprehensive benefit package, including: medical, dental, vision, 401(k) plan, unlimited paid time off, generous parental leave plan, and others for mental and wellness support.
