ABOUT YOUR ROLE We are looking for a Design Engineer to join our Design team. This is a senior-level Individual Contributor role that lives at the intersection of design and code. You will own the quality bar for UI across our product suite, build production-grade implementations of designer concepts, and create the systems and workflows that let the design team ship faster with AI. You'll report to Design leadership and work day-to-day alongside our product designers, with close collaboration across Engineering. You are the person who makes sure our product looks and feels as good as it was imagined. You notice the details others skip and care about the last-mile polish that makes a product feel unified and considered. Our product is genuinely complex. We serve investment managers navigating fund accounting, investor portals, and data-heavy reporting workflows.Making it feel clear, fast, and well-crafted is the job. AI fluency is a baseline expectation. You use tools like Cursor and Claude Code as natural extensions of your workflow: prototyping, exploring interactions, generating production-grade starting points. You have sound judgment about when to reach for a tool and what to do with the output. WHAT YOU’LL DO - You are the quality bar for UI across the product. Identify rough edges, propose fixes, and ship improvements, often autonomously, without waiting for a ticket. - Own the last-mile details: consistent spacing, transitions that land right, interactions that don't jar. If something feels slightly off anywhere in the product, that's your domain. - Build production-quality UI components and interactions that close the gap between what was designed and what actually ships. - Help designers ship in code. Build the workflows and tooling so that designer-made prototypes are structured starting points that engineers and AI agents can work from directly. - Create the handoff layer between design and engineering: organize and structure designer-generated code
