Job description

We’re partnering with an innovative organization launching a new AI-powered SaaS platform that enables nontechnical users to build customized business applications through natural-language interaction. This is an early-stage product with significant growth potential and a small, highly technical team building it from the ground up.

We’re looking for a Product Designer who thrives in that kind of environment: creative, technical enough to work closely with engineers, highly autonomous, and comfortable turning ambiguity into thoughtful, intuitive product experiences.

This is an opportunity to have substantial influence over the product’s design language, user experience, and design system at an early stage.

What You’ll Do

• Own product design across complex B2B SaaS workflows, from concept through shipped experience
• Build and evolve the product’s design system, including reusable components, patterns, states, tokens, and usage guidelines
• Design intuitive experiences that allow nontechnical users to interact with AI and create sophisticated applications
• Partner closely with software engineering, data science, and product stakeholders
• Identify patterns in inconsistent or ineffective AI-generated interfaces and develop scalable design solutions
• Design workflows involving permissions, governance, version history, auditability, and other complex product functionality
• Create prototypes and iterate quickly based on user feedback and product needs
• Apply accessibility best practices, including WCAG 2.1 AA standards
• Work comfortably with HTML/CSS when needed to evaluate or refine front-end implementation
• Help establish design processes and standards as the product and team grow

What We’re Looking For

• Approximately 4–6 years of product design, UX/UI, or closely related experience
• Experience designing and shipping complex software products, ideally within B2B SaaS
• Strong Figma skills, particularly components, variables, prototyping, and design systems
• Demonstrated experience building or significantly contributing to a design system
• Working knowledge of HTML/CSS and the ability to collaborate effectively with engineers
• Strong understanding of interaction design, information architecture, accessibility, and responsive design
• Portfolio demonstrating product thinking, workflows, edge cases, and shipped solutions rather than visual design alone
• Ability to operate independently without a large design organization or extensive direction
• Comfortable working in a fast-moving environment where requirements may evolve quickly

Especially Interesting Backgrounds

Experience with any of the following would be highly valuable:

• AI-native or generative AI products
• Conversational UX
• Low-code or no-code platforms
• Workflow automation
• Internal business applications
• Zero-to-one or early-stage product development
• Startup or entrepreneurial environments

Who Will Thrive Here

This role is ideal for someone who enjoys building rather than inheriting.

You should be comfortable walking into an environment where not every answer, process, or design standard already exists. You’ll have the opportunity to create those standards, test ideas quickly, work directly with technical teammates, and make a meaningful mark on a product at a very early stage.

The strongest candidate will combine creativity with structure: someone who can imagine a better experience and then build the system necessary to make that experience consistent and scalable.

Location

Candidates should be located in the Jacksonville, Florida area and comfortable with an increasingly in-person working environment as the team grows.
