Principal Front-End Engineer

Join the Team Reinventing the Brick & Mortar Shopping Experience at IOB

Imagine working at a company where you experience the best of both worlds: the fast-paced execution of a startup paired with the guidance of leaders who have built successful scalable solutions. Led by seasoned innovator Hannes van Rensburg, we’re not just rethinking the evolution of physical retail—we’re redefining it.

At The Internet of Behaviors Company (IOB), we envision a future where physical shopping becomes an enjoyable social and retail experience once again. Customers will receive curated offerings, guaranteed selections, and delightful interactions. Our goal is to connect physical storefronts with customers in a way that rivals the convenience of online shopping. We’re looking for great teammates to help us shape the future of connected retail, and we invite you to join us.

We believe that physical retail is NOT dead; rather, it has yet to evolve alongside today’s modern customers. Many shoppers are migrating to online platforms because physical retail has fallen short in convenience, selection, pricing, and enjoyment. Shopping used to be a pleasurable pastime, and IOB is committed to bringing back that enjoyment. We need your expertise to make it happen. You will be part of a skilled team that is fundamentally reshaping physical retail, which still accounts for 80% of the overall industry. Together, we will invent a new standard for customer experience, personalized service, and ultimately, a delightful way to shop.

You will work alongside some of the brightest minds in technology, develop cutting-edge software and hardware solutions, and be empowered to tackle challenging problems that will stretch your skills and enhance your thinking. If you’re ready to join us in building the future of connected retail, we want to hear from you.

About the Team & Role

At IOB, we craft intuitive and powerful user interfaces that enable seamless interaction with cutting-edge technologies in IoT, data analytics, and beyond. Our Front-End Team is at the forefront of this mission, building responsive and accessible web and cross-platform applications that are as functional as they are beautiful.

As a Front-End Engineer, you'll work closely with our UI/UX designers on Figma to transform ideas into polished, performant user experiences. Our primary stack includes Angular for web development and Ionic’s Capacitor for cross-platform iOS and Android apps. You'll leverage tools like Redux for state management and functional programming patterns to create scalable, maintainable codebases.

In this role, you’ll contribute to designing and implementing new applications and features while continuously improving existing solutions. You'll collaborate with back-end engineers, designers, and stakeholders to ensure our products are both visually stunning and highly functional, meeting the needs of our diverse user base.

If you're passionate about modern front-end technologies, thrive on turning design concepts into reality, and enjoy solving complex challenges in web and mobile app development, we'd love to have you join our team.
