Senior UX Designer

Summary:

The Product Design team at Cosm is looking for a Sr. UX Product Designer to bring real craft and ownership to our internal tools - the applications our teams depend on to operate our venues.  This is a high-impact role for a seasoned designer with sharp UX/IA instincts, strong product thinking, and a genuine appetite for untangling complex workflows and systems.

You'll take a critical look at how our tooling and information architecture is structured today, and shape where it goes. If you thrive on 0-to-1 challenges, sweat the details, and want your fingerprints on the infrastructure as well as the interface, this role is for you.

Responsibilities:

• Define and drive the design direction for our internal and B2B backend tools, from information architecture and system design through to polished, production-ready interfaces.
• Audit and organize our existing backend toolset - mapping how features, workflows, and systems relate to one another and identifying where consolidation, clarity, or restructuring will have the most impact.
• Leverage AI tools and prototyping to build and validate ideas directly - you're comfortable getting your hands into production, not just handing off specs.
• Lead features end-to-end: partnering with product managers and engineers to gather requirements, frame problems, iterate on solutions, and deliver organized, well-documented work.
• Hold a high bar for the UX of every tool you touch, with each one feeling considered and purposeful, not just functional.
• Own the full arc from strategy to pixels, exercising your own judgment to move work from concept to implementation.
• Present and defend design decisions clearly to stakeholders, grounding your rationale in user needs and business impact.
• Collaborate closely with engineering and data teams to design interfaces that make complex, high-density information legible and actionable
• Mentor other designers on the team, offering direct and constructive feedback that raises the quality of the work.
• Foster a culture of honest, empathetic communication and high craft.

Experience:

• 7+ years of technical product design experience in software, with a track record of shaping complex products, ideally tools, ops, or B2B applications.
• Deep UX and IA chops: you can untangle messy workflows, rethink information hierarchies, and design systems that scale.
• Strong product thinking: you understand the "why" behind the work and can hold your own in conversations about strategy, tradeoffs, and prioritization.
• Experience shipping work with AI tools; you treat them as a creative and technical accelerator, not a novelty.
• Experience maintaining or contributing to a design system used across multiple product surfaces.
• A portfolio that shows evidence of systems thinking, end-to-end ownership, and work built in fast-paced product organizations.
• High proficiency in Figma and a habit of pulling in new tools and technologies when they make the work better.
• Excellent communication and presentation skills: you can walk a room through a complex system and make it legible.
• A bachelor's degree or equivalent combination of education and experience in design, HCI, or a related field.

The annualized base salary range for this position in California is $150,000- $175,000. The base salary offered will factor in internal equity and may also vary depending on the candidate's geographic region, job-related knowledge, skills, and relevant experience, among other factors.
