The RoleWe are seeking a Senior Frontend Software Engineer to drive the delivery of large, complex UI features, lead architecture and design improvements, and mentor engineers across the team. Working as a senior technical contributor, this role focuses on advancing modern front-end technologies, design systems, and user-centered engineering while contributing significantly to technical strategy. You will have the opportunity to lead major UI initiatives, promote scalable architecture and accessibility, and elevate engineering best practices across the organization.
The ideal candidate is a seasoned engineer (7+ years) who understands that front-end architecture is the bridge between technical feasibility and exceptional user experience. This position will lead complex UI initiatives, mitigate technical debt, and ensure our front-end ecosystem is performant, accessible, and built for long-term scalability.
Essential Responsibilities- Lead the implementation of large-scale frontend features with minimal oversight
- Design reusable architecture patterns and contribute to the evolution of shared tooling and design systems
- Identify and resolve performance bottlenecks and accessibility issues at a systemic level
- Serve as a mentor to associate and mid-level engineers, providing technical guidance, code review feedback, and pair programming support
- Collaborate with cross-functional partners and design teams to clarify ambiguous requirements and align UI implementation with product strategy
- Influence roadmap priorities through technical feasibility insights and proactive risk mitigation
- Utilize Advanced Front-End Technologies to:
- Build interactive 2D/WebGL frontends using Pixi.js and optimize performance via Web Workers
- Integrate AI developer workflows and AI capabilities into front-end applications
- Optimize applications using code splitting, lazy loading, performance profiling tools, and CI/CD testing frameworks
Required Skills & Qualifications- Advanced Front-End Architecture: Deep technical expertise in JavaScript, TypeScript, React, HTML, CSS, and modern front-end architectural patterns.
- Tooling, Testing & Workflow: Experience with testing frameworks (e.g., Playwright, Vitest, Jest, React Testing Library), modern build tools/bundlers (e.g., Vite, Webpack), CI/CD pipelines, and AI developer workflows.
- Specialized Graphics & Performance: Hands-on experience building interactive 2D/WebGL frontends using Pixi.js, optimizing browser performance via Web Workers, and utilizing profiling tools.
- Engineering Experience & Mentorship: 7+ years (or equivalent demonstrated depth) of experience in front-end software engineering, with a proven track record of mentoring junior and mid-level developers and driving architecture reviews.
- Systemic Quality & Accessibility: Deep knowledge of web accessibility standards, system-level performance optimization, and design system engineering.
- Technical Communication & Alignment: Exceptional written and verbal communication skills across technical and non-technical audiences, with a proven ability to build consensus and refine user flows.
- Strategic Awareness: Demonstrated ability to align front-end technical strategy with business goals, deconstruct complex features into iterative components, and mitigate technical debt.
