Whether you’re remote or office-based, you’ll collaborate with talented colleagues across departments and time zones, united by the mission to create a safer digital world. We invite you to apply today! SimSpace is investing in the craft, consistency, and quality of every interface our customers touch, as well as in the systems that make great UI possible at scale. Our Core UI team owns the foundation the rest of the product is built on: our design system, shared component libraries, frontend architecture, and the partnership between engineering and UX Design. As a Staff Software Engineer on Core UI, you'll be the senior-most technical voice on the team—setting frontend architecture and standards, leading complex UI initiatives end to end, and contributing directly to the systems every product team depends on. You'll partner deeply with UX Designers, Product Managers, and engineers across the organization, and your technical leadership and mentorship will be key to helping the team raise its bar. This is a hands-on technical leadership role, not a people-management one. You set direction through architecture, code, and influence—staying close enough to the work to make the hard calls, unblock difficult problems, and hold a high bar for craft, accessibility, and performance. We're looking for an experienced engineer who wants real ownership of a domain and treats the frontend platform as a product. WHAT YOU'LL DO SET TECHNICAL DIRECTION & ARCHITECTURE - Serve as the senior-most technical voice for SimSpace's core frontend, owning architecture decisions and the technical roadmap for shared UI systems. - Lead major frontend initiatives end to end—from requirements gathering and architecture design through delivery—setting clear goals, priorities, and technical direction. - Steward architectural decisions and manage technical and UX debt deliberately, balancing long-term health with delivery needs. - Define and enforce frontend technical standards for code health, performance, testing, and documentation. - Mentor Design Engineers and frontend engineers, modeling strong craft, collaboration, and pragmatism.
