UX Designer — Evlo AI, Boston, MA

About The Role

The role sits at the intersection of product strategy, interaction design, and user research - owning how complex workflows translate into interfaces that feel obvious to real users. The scope covers a B2B SaaS platform with dense, data-heavy screens where usability is a competitive moat, not a nice-to-have.

This is a hands-on design role: the person hired will run discovery sessions, ship production-ready design specs, and validate decisions through usability testing. Expect close daily collaboration with product managers and frontend engineers, not design work done in isolation.

Key Responsibilities

• Own end-to-end design for major feature areas: discovery, wireframes, high-fidelity mockups in Figma, and annotated specs for engineering handoff

• Plan and run moderated usability studies and user interviews (5-8 participants per round), synthesizing findings into prioritized, actionable recommendations

• Design and iterate on the shared design system - components, tokens, and patterns - ensuring consistency across web and mobile-responsive surfaces

• Partner with product managers to frame problems, define success metrics, and pressure-test scope before engineering work begins

• Conduct rapid usability testing on prototypes (Figma, Maze) to validate flows before build, and run post-launch evaluations on shipped work

• Analyze behavioral data (Amplitude, Hotjar, session replays) to identify friction points and inform the design roadmap

• Present design rationale to cross-functional stakeholders and leadership, defending decisions with evidence from research and testing

What We Are Looking For

• 3–6 years of professional UX design experience, with a portfolio demonstrating shipped work on complex, data-dense B2B or productivity products

• Expert-level Figma skills, including component libraries, auto-layout, and collaborative prototyping

• Demonstrated experience planning and conducting both qualitative research (interviews, usability tests) and quantitative analysis (surveys, funnel data)

• Strong grasp of accessibility standards (WCAG 2.1 AA) and responsive web design principles

• Experience working with design systems - contributing to or maintaining a shared component library

• BA/BS in HCI, Interaction Design, Psychology, or equivalent practical experience

• Bonus: experience with front-end fundamentals (HTML/CSS fluency), motion design, or building design tokens in a multi-platform environment
