Senior Designer Jobs in San Francisco, CA

About Assembled

Great customer support requires human agents and AI in perfect balance, and Assembled is the only unified platform that orchestrates both at scale. Companies like Canva, Etsy, and Robinhood use Assembled to coordinate their entire support operation — in-house agents, BPOs, and AI — in a single operating system. With AI Agents that resolve cases end-to-end, AI Copilot for agent assistance, and AI-powered workforce management that optimizes both human and AI capacity, Assembled helps teams deliver faster, better service while making smarter decisions about how to staff and automate. Backed by $71M from NEA, Emergence Capital, and Stripe, we're building the platform that makes AI and human collaboration actually work.

The role

We're looking for a product designer to own the experience of our AI support products end to end: how support teams build, trust, and improve AI agents, and how those agents show up for the people who need help. You'll join a product that's already delivering value for customers and entering its next phase of growth. Over the past few years we've built a comprehensive AI support platform spanning chat, voice, monitoring, knowledge, and agent operations. The opportunity now isn't to invent a product from scratch—it's to help define what great AI-powered support looks like as the category rapidly evolves. You'll work directly with customers, engineers, and company leadership to shape both the near-term product and the long-term vision. The conventions for agent UX are still being written, and many of the most important questions around trust, transparency, control, and human-AI collaboration remain unsolved. You'll help answer them. This is an onsite role based in our San Francisco office, five days a week (Monday–Friday).

What You'll Own

- Design self-serve AI agent experiences that enable support and operations teams—not engineers—to configure, deploy, monitor, and improve AI agents.
- Shaping new product areas from concept to launch. You’ll clarify messy customer problems, explore solution directions, align the team, and ship experiences that customers use in production.
- Defining interaction patterns for AI-backed support. You’ll design durable primitives for building, observing, evaluating, and improving agents.
- Leading customer-centered discovery. You’ll spend time with support teams, understand how they actually operate, and translate that into product decisions the whole team can rally around.
- Prototyping quickly and concretely. You’ll use Figma and AI tools to explore ideas, test flows, and make abstract agent behavior feel tangible.
- Raising the craft bar. You’ll contribute to our design system, improve visual and interaction quality, and help make complex workflows feel clear and approachable.

What Excites Us

- 3+ years designing and shipping production B2B software. You're drawn to complex domains and can distill messy input from many people into clean, useful primitives, trading off simplicity and flexibility well.
- You can turn ambiguity into shipped product. You’re comfortable starting with an unclear problem, finding the signal, framing the tradeoffs, and driving toward a high-quality launch.
- You’re strong at systems and interaction design. You can design reusable patterns, think in primitives, and balance simplicity with flexibility as a product grows.
- Customer-driven. You love talking to users, you keep projects anchored to real needs, and you help others stay anchored too.
- You’re a strong communicator. You communicate clearly in writing and conversation, and can bring customers, engineers, and teammates along with your thinking.
- You've designed products for non-technical operators and know how to make powerful systems approachable without sacrificing flexibility.

Nice to have

- You get into the code. You've used coding agents to build, prototype, or ship product experiences yourself, and you're eager to take advantage of tools that let designers own more of the path from idea to reality.
- AI fluency in practice. You're already using AI tools (Cursor, Claude, and whatever comes next) in your design workflow and have an informed view of what AI can and can't do today.
- Prior experience designing AI, agent, or conversational products. You've worked on products that involve AI-driven workflows, agent experiences, or human-AI interaction, and have developed intuition for designing around trust, transparency, and control.
