(Senior/Staff) Product Designer

THE TEAM YOU'LL JOIN - DESIGNING THE INTERFACE BETWEEN HUMANS AND AI AGENTS IN PROCUREMENT Tacto builds AI-powered software for strategic procurement teams in manufacturing. Our customers manage millions in spend, negotiate with hundreds of suppliers, and make decisions that directly affect their company's bottom line. We're entering a phase where the product fundamentally changes shape. Instead of dashboards users click through, we're building agentic capabilities that take larger units of work off our users' shoulders - monitoring markets, preparing negotiations, flagging risks, executing workflows end-to-end. The agent handles the work. Humans make the decisions and review the results. How that actually shows up in the app - especially for non-technical procurement professionals who are the majority of our users - is one of the hardest design challenges we face. That's where you come in. You'll join a small design team and you'll work alongside product managers, engineers, and domain experts who understand procurement deeply. Your job is to make AI capabilities feel natural, trustworthy, and genuinely useful to people who've never thought of themselves as "tech users." WHY THIS ROLE MATTERS The shift from "tools you operate" to "agents that work for you" is happening across the industry - but most teams are still figuring out what that means in practice. For our customers, the stakes are high: a misunderstood recommendation or a confusing workflow doesn't just frustrate users, it costs real money. If we get this right, procurement teams will trust Tacto to handle the heavy lifting while they focus on the decisions that matter. If we get it wrong, the most powerful AI capabilities in the world won't get adopted. Design is the difference. 💪 YOUR IMPACT In this role, you will: - Shape how agentic capabilities surface in the product - from "the agent is working on this" to "here's what it found, here's what you should decide." - Design flows where AI and human judgment work together, not in parallel. Think less "copilot sidebar" and more "the product just handles it and comes back when it needs you." - Create short-horizon vision work (3-6 months out) that points the team in a direction - not as polished decks, but as prototypes and tangible artifacts the team can react to and build toward. - Raise the bar for craft and coherence across the product, especially as engineering velocity increases 10x and more features ship faster. - Work directly in code for last-mile polish - checking out PRs, tweaking interactions, making things feel right before they ship. WHO YOU ARE We're looking for a block-shaped designer. Not a T-shape with one deep skill and broad awareness, but someone who is genuinely strong - 80th percentile good - across multiple disciplines: visual design, interaction design, product thinking, and prototyping in code. This matters because the role stretches. You'll think like a PM when shaping what to build. You'll think like an engineer when prototyping and polishing in code. And you'll think like a designer when making it all feel coherent, clear, and worth trusting. You'll be a great fit if you: - Are a senior designer with a strong portfolio of shipped product work - ideally in B2B SaaS, complex workflows, or data-heavy products. - Have real opinions about how AI should show up in products - not just "add a chat interface," but genuinely thoughtful about trust, transparency, and when AI should get out of the way. - Prototype in code as part of your regular workflow. Figma is still valuable, but you move past it when a real prototype communicates the idea better. - Think in systems, not just screens. You care about how 20 features feel together, not just how one flow looks in isolation. - Can operate with ambiguity. The problems we're solving don't have established patterns yet - you'll have to invent some of them. - Organize your day using AI tools. You use Claude, ChatGPT, Cursor, or similar as core leverage in
