About the role

Key responsibilities & impact

Drive end-to-end design for complex, multi-step SaaS products — from early-stage problem framing through high-fidelity prototyping and handoff.
Lead the creation of cross-platform user flows, interaction models, and design specifications that translate cleanly to engineering.
Design AI-native product experiences — including conversational UI, predictive features, AI output states, and human-AI interaction patterns — with the same rigor applied to any other product surface.
Leverage AI design tools and agentic workflows to accelerate exploration, generate design variations, and reduce time-to-validation.
Champion design quality across the team, establishing patterns and raising the bar on craft, consistency, and usability.
Plan and execute user research — generative and evaluative — to continuously inform product direction.
Synthesize qualitative and quantitative signals (usability studies, analytics, customer feedback, market analysis) into clear design recommendations.
Work fluently with product analytics tools (e.g., Amplitude, Mixpanel) — pull your own data, form hypotheses, and connect design decisions to measurable outcomes.
Identify friction and opportunity in existing experiences; drive validated improvements backed by evidence, not assumptions.
Frame design problems with clarity — connecting user needs to business outcomes and technical constraints.
Actively contribute to product strategy conversations; push back constructively when proposed solutions don't serve users or undermine long-term product integrity.
Collaborate cross-functionally with product, engineering, and stakeholders throughout the full design-to-delivery cycle.
Contribute to and maintain the team's design system, ensuring consistency and scalability across the product surface.
Mentor and coach junior and mid-level designers; provide structured, actionable feedback on work and process.
Model how to use AI tools thoughtfully in a design workflow — not as a shortcut, but as a multiplier for quality and speed.
Help shape team processes, critique culture, and design standards.

Requirements

What you’ll need

8+ years of product design experience, with demonstrated progression into a lead or senior IC role.
Portfolio showing end-to-end ownership of complex B2B or enterprise SaaS product design — design thinking, not just visual execution.
Deep proficiency in Figma, including component libraries, auto-layout, and prototyping.
Hands-on experience with design systems — building, scaling, and governing them.
Strong research chops: usability testing, interviews, synthesis — you know when to do which and how to act on what you find.
Demonstrated data literacy: comfortable pulling and interpreting product analytics to inform and validate design decisions.
Proven ability to influence product direction and navigate stakeholder dynamics with confidence and clarity.
Familiarity with front-end principles (HTML/CSS concepts); enough to design with engineering constraints in mind.
