• Willingness to be in-person in NYC and collaborate with engineers and founders.
• Rapid learning across new domains and technologies.

Responsibilities

• Build and redesign user-agent interactions across surfaces from sketch to release.
• Invent agent-ready UI primitives that agents assemble and explain in real time.
• Partner with product design to integrate working agents into products.

Job description

About Basis

Basis builds real agents that do real work in the real economy. Our agents operate for hours at a time, performing end-to-end work for some of the largest accounting firms in the world.

We recently raised $100M at >$1B valuation and are racing to deploy the most advanced applied ML at production scale.

Our investors include: Khosla Ventures (Keith Rabois & Vinod Khosla), Accel (Miles Clements), Google Ventures, Nat Friedman & Daniel Gross, Adam D'Angelo, Jeff Dean, Jack Altman, Noam Brown, Kyle Vogt, Amjad Masad, Clem Delangue and many other operators/technical leaders.

"Basis is on the frontier of building production-grade, long-horizon agents. They've pushed the limits of what we thought our models could do on real-world, economically valuable, complex accounting tasks. They've been a great collaborator in helping us shape what the future of agents looks like." — Prashant Mital, Applied AI Lead, OpenAI

About the role

Modern AI lets software reason in real time. That overturns decades of UX assumptions. A chatbot bolted onto old workflows won’t cut it; we need interfaces where humans and agents co-create work, hand tasks back and forth, and build trust in real time.

You will lead Basis into that design unknown: design both the screens accountants see and the invisible UI “toolbox” agents draw from when they assemble those screens.

Imagine Basis 18 months out, then ship toward it one prototype at a time.

Location: NYC, Flatiron office. In-person team.

What you'll do

Build

• Design and redesign user-agent interactions across multiple surfaces, from first sketch to polished release

• Invent agent-ready UI primitives that agents can assemble, edit, and explain in real time

• Partner closely with product design on working agents seamlessly into new and existing products

Understand our many accounting users

• Building really good systems here start from deep user empathy. You will spend a portion of your time actually doing accounting work in Basis and becoming a user

Be a visionary

• Pair with founders to sketch Basis 2027, then distill it into quarterly bets

Learn at warp speed

• Immerse in what makes accounting awesome, emergent abilities of LLMs, and various UX for generally-intelligent software, then turn that insight into product decisions

What we're looking for

• Experience: 4–8 years designing complex SaaS or AI tooling, with at least one 0→1 launch (extraordinary talent with fewer years considered).

• First-principles reasoner: You break problems to fundamentals and rebuild without legacy bias.

• Agent-native builder: You already prototype with LLMs and can explain why they change UX.

• Use AI a lot: You should be using AI for your own work a ton. To learn, brainstorm, write, research etc.

• In-person NYC: You want the energy of five days a week on whiteboards with engineers, accountants, and founders.

• Learning velocity: New domains (hello, accounting!) and new tech click for you in weeks, not months.

• Whiteboard-to-Figma range: Comfortable sketching flows live with engineers, then polishing interactions on your own.

• Autonomy & ownership: Happy to make decisions without a committee and own a problem space end-to-end.

• All-in mindset: High-intensity culture, high-upside equity, and a wide-open canvas sound perfect.

Bonus points

• Accounting: Practical knowledge of accounting principles.

• Product ownership: Experience owning a product end-to-end
