[Hiring] Head of UX/UI @Euler

Role Description

EULER is hiring a Head of UX/UI to own the end-to-end design experience across our platform. You'll lead our existing design team from day one while staying just as close to the craft yourself — equally comfortable running a design critique and designing in Figma, and spending real time doing both every week.

Reporting to the CTO, you'll own the UX/UI across every surface of the EULER product, designing for two distinct user types — partnership managers on the customer side, and channel partners on the other.

You'll manage and grow the designers we already have, set the standard for the function, and still contribute directly on the highest-leverage work. Our design work lives in both Figma and Claude (Claude Design and Claude Code), and we are actively evolving it into a workflow that is easier for developers to build from.

Key Responsibilities

• Lead, manage, and mentor our existing team of designers from day one.
• Run regular design critiques and give specific, actionable feedback.
• Own the design process end to end — how work is scoped, reviewed, handed off, and measured.
• Grow the team over time: define roles, evaluate portfolios, and run design hiring.
• Be the connective tissue between design, product, and engineering.
• Guide the team in adopting Claude Design and Claude Code as part of their daily workflow.
• Contribute directly as an individual contributor on the highest-leverage and most complex design work.
• Own the UX/UI vision and execution across all EULER product surfaces.
• Build and maintain a cohesive design system in Figma.
• Prototype and iterate across Figma, Claude Design, and Claude Code.
• Own the engineering handoff: deliver specs precise enough to leave no room for interpretation.
• Run user research and usability testing to ground design decisions in real user behavior.
• Identify friction points across the product and proactively design improvements.
• Track and own design's impact on product adoption and engagement.

Qualifications

• 6+ years of UX/UI design experience in B2B SaaS.
• At least 2 years leading a design team in a fast-paced, small-team environment.
• A track record of both managing designers and personally shipping high-quality product work.
• A strong portfolio showcasing end-to-end product design.
• Expert in Figma — design systems, design tokens, component libraries, prototyping, and engineering handoff.
• Hands-on experience with, or strong enthusiasm for learning, Claude Design and Claude Code.
• Experience designing for multiple user types with different mental models and goals.
• Proven ability to lead research, synthesize findings, and translate them into design decisions.
• Comfortable owning design metrics — adoption, engagement, task completion.
• Collaborative and opinionated — bring a clear point of view.
• Comfortable working in a fast-moving environment.
• Exceptional written and spoken English.

Benefits

• Own the UX/UI function at a profitable, fast-growing SaaS company.
• Lead a design team while staying hands-on in Figma.
• Work at the leading edge of AI-assisted design.
• Design for a product with two distinct user experiences and genuine complexity.
• Build and evolve the design system in parallel with new features shipping constantly.
• Work directly with the founders, with a direct line to product and engineering decisions.
• Real traction: 600% YoY growth, enterprise customers, and a category wide open for disruption.
• A small, high-impact team that values speed, ownership, and craft.
• Competitive salary and benefits.
