About The Position

FloQast is hiring a Senior Design Engineer to help build and scale the design organization behind its AI-powered Accounting Platform. The role combines enterprise UX expertise with production front-end engineering, with a focus on creating human-centered tools that make complex financial data intuitive and support AI-assisted accounting workflows. The engineer will build and ship FloUI, FloQast’s shared component library, in partnership with Design Systems Leads and Platform Engineering. They will standardize high-impact UI patterns, own the token pipeline, and maintain alignment between Figma variables and code. They will also partner with engineering teams across US West Coast and India business units, establishing asynchronous contribution practices, PR review guardrails, and Storybook documentation. The position will develop front-end patterns suited to AI-native interfaces, including design tokens, semantic UI trees, and dynamic streaming interfaces. It will also create functional React and TypeScript prototypes for testing complex AI workflows, establish tooling that helps designers and product managers contribute usable front-end code, and collaborate with product designers on enterprise UX strategy. Additional work includes auditing legacy UI code, planning deprecations, and promoting accessibility, responsive design, and performance across data-dense interfaces. The role requires working in the office three days per week; this requirement may change based on team and business needs and is subject to ongoing review. Visa sponsorship is not available. The base pay range is $180,000–$230,000.
