Lead UX Designer

Salary: $8,000-$15,000 per month

Hybrid: 4 days on-site/1 day remote (Office located in Warsaw)

Full-time position, long-term

Contract type: B2B

We are hiring a Lead UX Designer for an enterprise AI company building a platform that lets AI agents work reliably inside complex business environments. This is a senior individual-contributor leadership role focused on AI experiences: you set the design bar for the whole product and mentor other designers. You report to product leadership and partner closely with engineering.

Responsibilities

• Own the design craft bar for the core product, covering visual quality, interaction quality, and consistency across the product
• Design trustworthy interfaces for complex AI and agentic systems, including streaming responses, uncertainty, confidence and sources, agent actions, error and recovery, and human-in-the-loop control
• Turn ambiguous product problems into clear flows, prototypes, and shipped experiences
• Make complex, technical capability accessible to non-technical business users, and design onboarding that gets them to value quickly
• Apply engagement and light gamification deliberately to keep the product approachable and rewarding to use
• Build and extend the design system so the product stays coherent and the team ships faster
• Ground design decisions in real user understanding through research, usability testing, and direct customer contact
• Partner closely with product and engineering from problem framing through production, so what ships matches the intent
• Mentor other designers and raise the craft bar across the team through critique and example
• Drive an AI-native design workflow, using AI across exploration, prototyping, content, and research synthesis while keeping a high verification bar

Requirements

• 7+ years in a product design role, with a portfolio that proves your craft on the difficult screens too: empty states, loading, errors, and edge cases, not just the clean happy path
• Can explain what makes a design work across layout, type, interaction, density, and motion
• Product instinct that catches broken flows, lazy defaults, and clutter, and that ties every design choice back to what users and the business actually need
• A background in dense, data-rich, or enterprise tools, not only consumer apps or marketing pages
• Proven ability to make hard, technical products feel easy, through onboarding, gradual reveal of complexity, and hooks that get people to their first win fast
• A structural mindset, having created or grown a real design system and thinking in terms of consistency and information architecture at scale
• Evidence-led practice, where your calls come from watching real user behavior, and you can name designs you changed after seeing the data
• A team-first, delivery-focused way of working, tight with engineers and PMs, and honest in critique
• A design process already wired around AI tools day-to-day
• Plain, clear communication, spoken and written

Nice to Have

• Prior work on AI or agentic products, whether copilots, chat and its successors, retrieval with cited sources, knowledge graphs, or similar systems
• The ability to build working prototypes yourself, in code or with current prototyping and AI tools
• A history of steering design direction and coaching peers, even with no direct reports
• A knowledge of enterprise and B2B SaaS constraints: access controls, audit trails, scale, and the workflows of operational users

We Offer

• Competitive salary range of $8,000-$15,000 per month
• Hybrid work model: 4 days on-site/1 day remote
• Office located in Warsaw, Poland
• Full-time position with long-term opportunities
• Collaborative environment with close partnership with product and engineering teams
