Product Designer - Agents
About us: At Pencil, we are driving innovation in advertising technology through our state-of-the-art SaaS product, which harnesses Generative AI to redefine content creation. Our mission is to make AI the default in advertising without replacing creative people. To achieve this, we need to make sure that our technology isn’t just in the hands of big brands - we need to try to help small businesses and creative individuals too. We’re hiring for a Product Designer to take full ownership of a core area of our platform—the Agent Marketplace. You’ll lead design from strategy to execution, working closely with Product and Engineering to shape features that help users create better ads with AI by leveraging specialized agents for real client use cases and third-party integrations. This role is ideal for someone who wants real responsibility, values clarity and speed, and thrives in an environment where each Designer drives their own part of the product. You won’t just push pixels; you’ll help define what we build and why, with a primary focus on delivering direct, immediate value to our clients. Key responsibilities: Own a core area of the Pencil platform end-to-end, from problem framing and concept exploration to final UI and shipped product. Partner closely with Product and Engineering to define and rapidly ship agents that solve real problems and maximize time-to-value for clients immediately upon delivery. Leverage integrations as a multiplier to unlock higher value through external tools and data, positioning the Agent Marketplace at the intersection of Pencil and external ecosystems. Design high-quality, production-ready interfaces for AI-driven workflows, expertly simplifying complexity to make experiences intuitive and predictable. Focus on agents that drive high adoption and reuse, prioritizing value over sheer volume. Ensure design intent is fully translated into development by working closely with engineers during implementation, reviewing builds, and iterating until the quality bar is met. Conduct user research by staying close to clients and commercial teams to ground decisions in real business problems, and continuously raise usability and clarity across the product. Use and contribute to our design system, helping to standardize just enough to maintain consistency without slowing down the speed of iteration. Your background: 5+ years of experience designing digital products, ideally within SaaS or complex, workflow-driven tools. A strong portfolio that demonstrates end-to-end product thinking, with a focus on translating messy client needs into clear, actionable agent concepts and shipped outcomes. Strong problem solver and fast thinker and doer who can move from idea to prototype quickly without over-relying on perfect inputs. Deep craft sensibility and a high bar for quality, with clear examples of attention to detail in UI, interaction, and system thinking. Proven ability to work autonomously in ambiguous environments, comfortable with shifting priorities driven by real client demands. Systems-aware designer who understands integrations and how different tools connect into a seamless experience. Strong experience working closely with engineers, with a clear understanding of how design translates into real production UI. Highly proficient in Figma, using it fluently to explore ideas, communicate intent, and evolve design systems. AI curiosity and comfort designing for AI-powered or data-driven systems, motivated to explore how AI can unlock new workflows and capabilities. This role is for you if… You are excited about creating specialized agents for real client use cases, not generic features, and see the marketplace as a key surface where AI delivers direct value. You are comfortable with ambiguity and thrive in a client-driven environment where the team needs to respond quickly to new opportunities as they appear. You are a Product-minded designer with a sharp instinct for what will actually drive usage and value. You are a Systems-aware designer who can see how integrations and different tools connect into a seamless experience. You’re excited by AI as a design material and want to help define new interaction paradigms. You believe great design comes from taste, iteration, and close collaboration.
