Founding Design Engineer

About Hanover Park

Hanover Park is building the AI-native fund administration platform for private markets. We administer over $15B in assets and are backed by Emergence Capital, Lux Capital, and Susa Ventures. Founded by Chris Hladczuk (CEO) and Nick Puljic (CTO), both Forbes 30 Under 30, we are a Series A company scaling from 50 to 100 people by the end of the year.

Private markets fund administration is a massive, underserved category. We think of our trajectory the way Veeva approached vertical software: same discipline, same entry point, with the ambition to define the category.

About the Role

We are hiring a Founding Design Engineer to own the craft of the product experience for the people who run the back office of private markets, fund controllers, treasury teams, and operators who need software that finally respects the complexity of their work.

Our product sits at an unusual intersection: dense, high stakes financial workflows that need to feel simple for a human operator, and increasingly, workflows where an AI agent is doing the work alongside that human. Designing for both at once, a human reviewing, correcting, and trusting an agent’s output in real time, is a genuinely hard and under-solved UI/UX problem. That is the core of this role.

This is not a role where design and engineering are handed off between teams. You will sit at the intersection, prototyping in code, shipping production UI, and making the judgment calls that usually get lost in translation between a Figma file and a pull request. You will own our design system and the tooling around it, setting the standards other engineers build against. You will work directly with Nick and the engineering team, and closely with product and ops stakeholders who live in the workflows you are building.

What You’ll Work on

• Own the craft and interaction quality of the product end to end, holding the line on detail and polish in a domain (fund accounting, treasury operations) that is inherently dense and complex
• Design and build the interaction patterns for workflows where humans and AI agents work side by side, including how a person reviews, corrects, and builds trust in agent-driven output in real time
• Own our design system and the tooling around it: components, patterns, documentation, and the best practices other engineers use to build consistent, high-quality UI
• Prototype rapidly in code rather than static mocks, using working software to test ideas with users and stakeholders
• Make the final call on product taste and interaction design in the areas you own, and build the judgment and context to be trusted with that call
• Partner with product, ops, and engineering to translate genuinely complex financial workflows into interfaces that feel simple and obvious in the hands of the person using them
• Work directly with customers and internal ops teams to see how workflows actually happen, and use that context to shape design decisions
• Balance speed and quality as a company still defining its product surface area, knowing when to move fast and when to slow down for the right long-term foundation

Stack

• TypeScript/React, Figma to code workflows (v0 or similar), our internal component library.

What We’re Looking For

Need:

• Currently hands-on, shipping user-facing product code today, not managing, reviewing, or architecting from a distance
• Exceptional taste: shipped work where the interaction design and craft are the reason it stands out, not just the functionality
• Strong full-stack fluency, comfortable owning a feature from database to UI, with particular strength on the frontend
• Experience with genuinely complex UI/UX: dense data, multi-step workflows, real edge cases, not just clean greenfield consumer surfaces

Nice to have:

• Experience designing for AI agent or automation-heavy products, especially human-in-the-loop review flows
• Background in fintech, capital markets, or other data-dense B2B software
• Experience building, owning, or significantly leveling up a design system, not just consuming one someone else built

This isn’t the right fit if:

• You need a spec or a design review board before you can start
• You want to hand off interaction decisions to someone else to make the final call
• You’re looking for a purely visual design role without the engineering to back it up
