The Company:

This is an incredible opportunity to join a forward-thinking company at the forefront of smart IoT technology, where you'll play a crucial role in shaping the future of efficiency and sustainability. From manufacturing to healthcare and renewables, this company's Real Time IoT monitoring solutions are transforming how organizations collect, interpret, and act on critical data.

With a suite of products like temperature sensors, environmental monitors, and energy usage trackers, their tools are integrated into sleek online dashboards delivering alerts, insights, and reporting in Real Time. This is a rare opportunity to shape both product functionality and design - building beautiful, intuitive user experiences powered by complex data.

The Role:

This is a hybrid role that blends Frontend Development with Product & UI/UX Design Leadership. You'll lead the development of modern, high-performing React applications while also owning the design language, visual consistency, and user journey of the product.

You'll collaborate closely with product, design, and Back End teams to deliver responsive, accessible, and user-friendly interfaces that bring IoT data to life. From wireframing and prototyping to writing clean, maintainable code, you'll play a critical role in shaping both how the platform looks and how it works.

Key Responsibilities:

• Design and implement modern, scalable UIs using React and TypeScript
• Lead the creation of a cohesive design system and reusable component libraries
• Translate complex datasets into clear, compelling data visualizations (Chart.js, D3.js)
• Own the end-to-end UX process - from user research and wireframing to testing and feedback
• Collaborate with stakeholders to align design decisions with business and user needs
• Integrate Front End with RESTful APIs and Real Time data streams
• Advocate for accessibility, performance, and best practices in Front End development
• Mentor junior engineers and contribute to a high-performing Agile team

Who They're Looking For:

Must-Haves:

• 3+ years of professional Front End development experience
• Strong skills in React, TypeScript, and modern CSS architecture
• Demonstrated experience leading or heavily contributing to design systems and UI/UX decisions
• Confident with data visualization tools and principles
• Experience in Agile environments and working in cross-functional teams

Nice-to-Haves:

• Exposure to IoT concepts and devices
• Familiarity with Back End environments (NestJS, AWS, Docker)
• Understanding of analytics, telemetry, or machine learning-driven UI design

This is a chance to have a genuine impact on a platform that's driving sustainability and innovation in IoT. Whether you're a senior Front End dev with strong design instincts, or a designer-turned-developer passionate about shaping UI from both sides, we'd love to hear from you.
