About Litmas AI

Litmas AI is building an agentic litigation platform that helps law firms handle complex litigation work, including legal research, drafting, evidence analysis and case preparation. We are creating software for demanding professional workflows where clarity, trust and quality matter.

The role

We are looking for a multidisciplinary UI/UX Designer to shape both the core application experience and the customer journey around it. You will turn complex B2B AI workflows into products that feel simple, intuitive and trustworthy, while also designing marketing journeys and landing pages that

explain the product clearly and convert interest into action.

This is a high-ownership role. You will work closely with the founders, engineering and go-to-market teams, speak directly with litigation attorneys, and take work from early discovery through production.

What you will do

• Own end-to-end UX and UI design for the Litmas AI web application, from problem discovery and user flows through prototypes, high-fidelity designs and implementation review.
• Conduct user research and workflow discovery with litigation attorneys and internal teams.
• Translate complex, data-heavy and AI-enabled workflows into clear product experiences that support confidence, review and control.
• Build and evolve a consistent design system and reusable component patterns.
• Design marketing journeys, landing pages, product pages and conversion-focused web experiences.
• Partner with the go-to-market team on launches and campaigns, ensuring the brand and product story are expressed clearly across customer touchpoints.
• Work closely with engineers during implementation, maintaining a high bar for usability, visual quality and detail.
• Use customer feedback and product data to iterate quickly and improve the experience.

What we are looking for

• 3-5 years of experience in UI/UX, product design or a closely related role.
• A strong portfolio demonstrating both application UX and polished visual design.
• Experience designing B2B SaaS, AI products or other complex, workflow-driven software.
• Ability to work across user research, journey mapping, wireframing, prototyping and high-fidelity UI design.
• Strong command of Figma, responsive web design and design systems.
• Comfort working in an early-stage environment, navigating ambiguity and taking ownership of outcomes.
• Strong communication and collaboration skills across engineering, product and commercial teams.
• A high level of attention to detail, with the ability to balance usability, speed and visual quality.

Bonus experience

• Experience in brand design, creative design or another visual design discipline.
• Experience creating conversion-focused landing pages, growth journeys or marketing websites.
• Front end coding experience
• Experience in legal technology or another complex professional domain.
• Skills in motion, illustration or visual storytelling.

Why join Litmas AI

• Meaningful equity in a growing startup
• Own parts of the product and customer experience from the outset.
• Work directly with founders, engineers and practising litigation attorneys.
• Help define how professionals use and trust AI in workflows.
• Join an ambitious team building a new category of legal software.

Please submit your CV and portfolio. Your portfolio should include examples of application UX, high-fidelity product design and, where available, marketing or brand work. Please make portfolio links available on CV if submitting directly through LinkedIn, or email "careers@litmas.ai". Only applications with portfolios will be considered.
