Job Description
Lead UX Designer
Billtrust
• 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.
Job Requirements
- 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.
Benefits
- comprehensive health coverage
- competitive retirement
- generous PTO and parental leave
- flexible work options
- meaningful investment in your professional development

NineTwoThree StudioWe build AI, Web & Mobile apps for Established Brands and Funded Startups.
• Lead the end-to-end design process, for client projects and the NineTwoThree brand, from concept to developer-ready handoff. • Work inside our existing component system (Chakra UI and its Figma UI Kit): reuse and extend it, customizing per client with minimal divergence and minimal engineering rework, instead of reinventing components. • Produce wireframes, prototypes, and high-fidelity UI in Figma to communicate solutions and test hypotheses. • Conduct competitive analysis and usability testing to validate decisions, favoring familiar, proven patterns over trends. • Treat developer implementation cost as a first-class design constraint: prefer the solution that ships fastest from our component library over the one that looks the most novel. • Innovate in information architecture and layout: decide what to surface, what to hide, and where things live, so the main workspace gets the screen space rather than endless menus, filters, and navigation. • Collaborate with product managers, engineers, and stakeholders to translate complex requirements into usable designs, and defend your decisions with user needs and business goals. • Speed up the design process with AI tools, and help raise the team's craft and design culture.
• Own end-to-end design across multiple product areas from concept through delivery • Translate complex product and technical challenges into intuitive, high-quality user experiences • Balance speed, experimentation, and craft across fast-moving initiatives • Design for engagement, retention, monetisation, and conversion at scale • Create and iterate on visual content (image + video) to support product exploration, in-product experiences, and marketing/growth surfaces • Contribute original product ideas and creative concepts • Identify opportunities beyond the immediate brief • Help shape new features and interaction patterns through proactive exploration • Push ideas further through experimentation and thoughtful challenge • Communicate design reasoning clearly and confidently • Defend ideas thoughtfully • Push back when needed • Collaborate effectively with Product, Engineering, and Leadership
