Job Summary

We re looking for a Senior UX Designer who sees complexity as a design challenge, not a given. You ll be the design voice in our engineering-led company, transforming enterprise software from "powerful but overwhelming" to "powerful and intuitive." You ll need to be comfortable in all stages of the design process—from watching users struggle with workflows to committing the CSS that fixes the problem.

You ll work closely with our design team, collaborate directly with engineers, validate your ideas with real users, and sometimes write the code yourself. You should thrive in ambiguity, love teaching yourself new tools, and get energized by being the only designer in the room. This position reports to the VP of Product.

Responsibilities

• Own the end-to-end design process for a complex enterprise product used by thousands of organizations
• Ruthlessly simplify: identify and eliminate unnecessary cognitive load in workflows, navigation, and UI patterns
• Build and evolve our design system—ensuring every component, pattern, and guideline serves users and scales with the product
• Get close to users: conduct research sessions, watch session recordings, analyze support tickets, and turn insights into designs
• Partner with engineering on implementation—you ll review PRs, provide feedback, and commit your own HTML/CSS fixes when it s faster
• Make strategic design decisions independently while keeping stakeholders informed
• Balance consistency with pragmatism: know when to follow the system and when the system needs to evolve
• Advocate for users without losing sight of business goals and technical realities

Qualifications

Required

• 7+ years designing products (preferably B2B, SaaS, or enterprise software)
• You ve been the only designer before—at a startup, on a product team, or in a similar high-autonomy role
• Portfolio showing how you ve tamed complexity: clear before/after examples, thought process, and measurable impact
• Comfortable with code: you can read HTML/CSS, navigate Git, and make basic commits without hand-holding
• Research-driven: you ve planned and conducted user interviews, usability tests, or contextual inquiries
• Design systems experience: you ve built, maintained, or significantly contributed to a component library or style guide
• Tool-agnostic but proficient in at least one modern design tool (Figma, Sketch, etc.)
• Experience working remotely with in-person teams, or you re based in Denver

Preferred

• You geek out about authentication flows, permission models, or developer tools
• You can write JavaScript or have worked closely enough with React to understand component thinking
• Comfortable using tools like Claude Code or Cursor to quickly prototype and test ideas
• You ve used analytics tools (Posthog, Metabase, etc.) to inform design decisions
• You ve shipped designs in open-source projects or developer-focused products
• You have strong opinions about design but change your mind when presented with better information
• You re comfortable being uncomfortable—startup chaos doesn t stress you out, it energizes you
• You understand that "perfect" is the enemy of "shipped" but never compromise on quality where it matters
• Adaptive to challenges common in a startup with under 100 employees
• Enjoys and thrives in a dynamic startup vibe
• Slight preference will be given to someone working out of the Denver, Portland or Seattle metro areas

Compensation

• $120-150k expected base salary range
