About Sapiom

Sapiom is building payment infrastructure for AI agents. We enable agents to make purchases for people, manage payments between businesses, and buy the compute, inference, and APIs they need to operate. As agents become part of everyday life, we're building toward the experiences people will use to trust them with their money: one place to set what agents can do, see what they did, and stay in control across every agent they use.

Through one integration, Sapiom connects agents to funding sources and payment methods. Our intent verification checks that each transaction matches what the person or business authorized. Spending controls define where and how much agents can spend, with a record of every transaction and its outcome. We're building toward a world where people and businesses can delegate payments to agents with confidence.

We're a small team in San Francisco with deep experience in payments and infrastructure. Our founder was Director of Engineering in Payments at Shopify for five years. We've raised $50 million in our first 12 months from Accel, Dragonfly, Coinbase Ventures, Okta Ventures, Menlo Ventures and Anthropic.

About the role

Agents are starting to act and transact on their own. For that to work, people have to trust them, and most of that trust is won or lost in the experience. This is a chance to define what design means in a new era: the experiences that make the agentic economy work for people haven't been invented yet. You'll design for developers building on Sapiom today, and help shape consumer experiences that put people in control of the agents acting for them.

For now, you'll be our only designer. You'll own how Sapiom looks and works, working closely with our founder, product and engineering: deciding what design needs to happen, taking problems from a rough idea to shipped product, and setting the standard for design across the company. This is a high-autonomy, Staff-level role. The right person is a systems thinker who's fluent in how AI agents work, uses AI to explore and build at a speed that wasn't possible before, and has the taste to separate great work from generic output.

What you will do

Own the end-to-end design process across Sapiom's product: from early discovery and requirements gathering with Product, through iterative visual design, to guiding implementation with Engineering. You'll work on the hardest UX problems in agentic commerce, where there's no playbook yet, and make autonomous activity clear and trustworthy to the people behind it.

You’ll also help define Sapiom’s design language and how our brand shows up in the market. Product comes first. The goal: software that earns developer trust on first use and deepens it every time.

Responsibilities

Own the full design process across product surfaces. Run design from early workshops and mockups to production-quality prototypes, delivering the right artifact at the right moment. Use AI to explore far more directions, prototype in code and automate the busywork, so your time goes to craft.

Partner with Product and Engineering to shape strategic direction, not just execute on spec, bringing design thinking into roadmap conversations early. Frame the highest-value problems in agentic commerce based on what developers and users need.

Ship interfaces for problems no one has solved before, across developer tools, consumer experiences and the conversations people have with agents.

Design the moments where people decide to trust an agent, so they feel safe at a glance wherever they appear, including inside a partner's product.

Build and maintain Sapiom's design system, and keep it consistent between Figma and code with an eye towards knowing when convention serves users and when a new pattern is necessary.

Set the bar for design quality across the company by establishing shared standards and giving and asking for feedback with candor.

Own Sapiom’s visual identity and support brand and marketing design when needed, so we become known for our design.
