Senior Frontend Developer II

SUMMARY:

• Deliver modern, component-driven apps for global smart home and security products
• Architect and scale the frontend of real-time video and sensor-based solutions
• Join a senior team building mission-critical software that lives at the edge

Bring your frontend depth to a team where code meets real-world impact. As a Senior Frontend Developer II , you'll take ownership of the user experience across our smart device ecosystem—designing, building, and optimizing the interfaces that control and monitor edge AI platforms deployed worldwide.

This role is for engineers who go beyond "pixel pushing" — we want system thinkers. You'll be shipping production-ready React apps, shaping UI architecture, contributing to design systems, and integrating directly with embedded devices, real-time APIs, and cloud platforms.

JOB DUTIES:

• Lead the development of performant, modular React frontends in a component-library-first environment
• Build design system-aligned UIs that scale across products and brands
• Collaborate with embedded, cloud, and product teams to integrate complex data and event-driven logic
• Deliver accessibility-compliant, production-grade apps (WCAG 2.1, ARIA, keyboard nav)
• Shape reusable architecture for theming, multi-tenancy, and extensibility
• Define testing pipelines with Cypress or similar frameworks
• Guide junior team members through code review and architectural decisions
Influence product through prototyping, stakeholder input, and UX alignment

YOU MUST HAVE:

• 5+ years in production-grade frontend engineering roles
• Frontend Tech: React, TypeScript, HTML/CSS, REST APIs
• UI Systems: Experience building or scaling design systems, component libraries
• Testing & DevOps: Cypress or equivalent, GitHub Actions, CI/CD familiarity
• Accessibility: Knowledge of standards (ARIA, semantic HTML, WCAG compliance)
Communication: Ability to work across design, embedded, and cloud teams to deliver end-to-end systems

WE VALUE:

• You bring a product mindset, engineering rigour, and a desire to create intuitive user experiences that sit atop complex systems.
• You’re hands-on, deeply technical, and think in systems, not just screens.
You mentor by example and obsess over performance, accessibility, and elegant UX.

WHAT'S IN IT FOR YOU:

• You’ll be building the front door to a world-first camera firmware platform — one that processes, detects, and responds autonomously to the environment around it. This isn’t just about dashboards — it’s about helping users manage intelligent, edge-first devices in real-time.
• Work on a platform with reach.
• Influence a product with impact.
Own a UI layer that makes intelligence visible.
