Senior Product Designer, AI

Lattice is a unified people platform dedicated to building the next generation of its AI-native product suite. They are seeking a Senior Product Designer to join their new AI team, responsible for creating innovative user experiences that integrate AI into the workflow of managers and employees.

Responsibilities:

• Shape and ship a reimagined way of capturing your work and growth, aligned with your manager and the business
• Work side-by-side with Product, Engineering, Data, and customers to land experiences that are loveable, measurable, and scalable
• Partner with engineering to craft and fine-tune the AI outputs themselves so they align with the ideal user experience
• Build a strong understanding of our entire product suite and collaborate with designers across teams to make sure AI strengthens, not fragments, the jobs our customers are already getting done

Requirements:

• 3 to 5+ years of product design experience, with meaningful time spent designing and shipping AI-powered experiences (chat, agents, AI-assisted workflows) or adjacent domains where you've designed for unpredictable outputs
• A 0→1 mindset that lives close to the customer: you've brought new experiences to life by forming hypotheses, prototyping, validating, and iterating to a shipped product, and you're energized by working with design partners, first-customers and beta programs, ongoing dogfooding, and the heavy validation we do before GA
• Curiosity and a love of figuring things out: AI is going to keep evolving, and a lot of today's best practices will be stale in a few months. You stay curious, experiment with new tools and patterns as they emerge, and treat every novel problem as an opportunity rather than a blocker
• Self-starting through ambiguity: autonomous and highly collaborative, comfortable driving your own discovery and synthesis with consultation from our research team, and willing to step into projects that are moving quickly and shifting under your feet
• An ability to think across multiple personas (managers, employees, admins, HR leaders) and help create a cohesive system for AI experiences across a broader product suite
• Experience designing for non-deterministic systems: you have a point of view on AI output quality and have shipped patterns for trust and graceful failure (hallucinations, confidence, citations, fallbacks, “I don't know” states, human-in-the-loop), thoughtful output formatting and tone, and streaming/latency so experiences feel fast and legible even mid-response
• A POV on AI voice, tone, and persona: you can help define who the assistant is and keep it consistent across surfaces, so AI feels like a coherent character rather than a scattered set of widgets
• Experience designing within complex, multi-product workflows: you can design scalable, durable, complex workflows, identify where AI should meaningfully augment a customer's job (or get out of the way), and slot new affordances in without breaking the broader experience
• UX craft: you shape problems before you solve them; identifying the real job to be done, mapping the edge cases that will matter at launch, and building clear mental models (matching them to AI when appropriate). You move fluidly from divergent exploration to a refined, shippable design, and you keep cognitive load low even when the underlying system is complex
• Advanced visual and interaction craft: you have a strong command of typography, hierarchy, spacing, grids, and responsive layouts, and you can produce high-quality UI that occasionally diverges from standard patterns when it elevates the product. You design detailed interaction patterns and partner closely with engineering on the quality of execution
• Proven success working with an established design system, reusing existing components and patterns, but you also have experience building new components and layouts where AI-native interactions require them
• A strong grasp of front-end implementation: you collaborate closely with engineering to ensure high-quality execution of detailed interaction patterns
• Strong written and verbal communication skills with a talent for succinctly articulating customer challenges and design decisions
• A reliable and proactive partner for Product and Engineering, upstream and downstream: you think at a high level with your PM and engineering partners to shape the future of what your team owns, and you stay close throughout the build, bringing your team along and ensuring every detail ships in a high-quality way
• A love for design feedback - both receiving and giving. You are someone who consistently shares your work with other designers and your cross-functional team, and who regularly engages with other designers' work
• A builder mindset: you're comfortable prototyping, working in coding tools, and using modern AI tools (i.e. Claude, Cursor, coding agents) to accelerate how you work
• An interest in applying AI tooling to your design process to increase efficiency, effectiveness, and depth of thinking
• You have experience shipping AI-native products at significant scale (high-volume production traffic, large user bases, or measurable business impact)
• You have experience in a hybrid role (Design & Product, or Design & Eng) or an equivalent background (i.e. shipping code or heavily contributing to product definition as a designer)
• You have worked in B2B SaaS
• You have a background or formal education in Graphic or Product Design
• You write front-end HTML and CSS or understand it well enough to have meaningful conversations about implementing your design work in production
