Mentor Design Engineers and frontend engineers, modeling strong craft, collaboration, and pragmatism.
Lead UI-focused initiatives end to end, balancing ideal UX outcomes with delivery realities.
Own SimSpace's core frontend repositories, design system (e.g., Monorail), component libraries, and overall frontend architecture-treating the platform as a product with a roadmap and measurable quality.
Own the relationship between engineering and UX Design, ensuring alignment between design (Figma) and implementation (code, Storybook).
Define workflows that turn design intent into production code predictably, and bring feasibility and engineering insight into design reviews early.
Lead, grow, and develop a team of Design Engineers and Core Frontend Engineers; own hiring, onboarding, 1:1s, performance, and career growth.
Support prototyping workflows that let UX research gather customer feedback and iterate quickly.
Partner with Product Management to align frontend work with business objectives and timelines, and maintain the plans and resourcing for predictable delivery.

Requirements

Track record of partnering closely with designers, PMs, and engineers across teams.
Hands-on experience with Agile methodologies, paired with strong leadership and communication skills.
In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification document form upon hire.
8+ years in frontend, UX, or design-adjacent engineering, including 2+ years directly managing or leading engineers.
Proven ability to lead and grow frontend or UX engineering teams, including distributed or hybrid teams.
Strong technical depth in TypeScript and React-modern component patterns and state management-enough to guide architecture and review work credibly.
Experience owning or substantially contributing to design systems or shared UI libraries used by multiple teams.
Solid understanding of accessibility (a11y) standards and how to operationalize them.

Nice to have

Frontend testing strategies (unit, visual, and accessibility).
Comfort across the stack when needed (API integration, backend collaboration).
Rapid UI prototyping and iterating against customer and UX research feedback.
Interest in AI-assisted UI development and prototyping.
Experience integrating work from contractors or external teams.
Bachelor's in Computer Science or a related field (or equivalent practical experience).
Hungry for ownership-you want a domain you can shape and set the bar for.
You care deeply about UX quality and craft, and operationalize it through systems and standards, not heroics.
