[Remote] Lead UX Designer

Note: The job is a remote job and is open to candidates in USA. Billtrust is a leader in B2B accounts receivable workflow and payment software, providing AI-powered solutions for finance leaders. The Lead UX Designer will drive product design strategy and execution, focusing on creating high-quality, AI-native product experiences and mentoring junior designers.

Responsibilities

• 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

Skills

• 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
• Experience designing AI-powered product features (conversational UI, predictive interfaces, AI error/confidence states)
• Hands-on use of AI design tools — generative UI, AI-assisted prototyping, synthetic user research methods, or similar
• Background designing for fintech, payments, or financial operations workflows
• Experience leading or mentoring other designers in a cross-functional product team

Benefits

• Comprehensive health coverage
• Competitive retirement
• Generous PTO and parental leave
• Flexible work options
• Meaningful investment in your professional development
• Extra incentives like equity, commissions, or other variable performance-related bonuses (if qualified)
