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 veteran innovator Hannes van Rensburg, we are not just rethinking the evolution of physical retail—we are 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, our mission is powered by robust and scalable back-end architectures that enable real-time analytics, machine learning, and advanced AI solutions. The Back-End Engineering Team plays a crucial role in this vision, ensuring that our services and applications operate seamlessly, securely, and efficiently across diverse workloads and environments. 

As a Back-End Engineer, you will be essential in designing, building, and optimizing the server-side components and microservices that form the backbone of our platform. This hands-on role provides the opportunity to leverage modern frameworks, APIs, and data-processing pipelines to drive performance and reliability at scale. Whether you are developing high-throughput APIs, streamlining database operations, or integrating with embedded systems, your contributions will help our team deliver innovative solutions for complex and unique customer deployments. 

If you are passionate about embedded systems, distributed architectures, and providing engineering teams with robust, scalable back-end services, we want you on our team.

• Database Expertise: Hands-on experience with PostgreSQL or MySQL or similar. 
• Architectural Knowledge: Practical experience with microservices and monolithic architectures; ability to weigh trade-offs between them. 
• Backend Fundamentals: Strong proficiency with RESTful APIs or GraphQL, data modeling, and designing robust application logic. 
• Security Awareness: Familiarity with common security vulnerabilities (e.g., OWASP Top Ten) and how to mitigate them. 
• CI/CD & DevOps: Experience with containerization (Docker), orchestration (Kubernetes), and modern CI/CD pipelines. 
• Cloud Services: Deploying and managing applications on cloud platforms (AWS, GCP, Azure). 
• Testing & Monitoring: Understanding of automated testing frameworks and monitoring tools. 
• Team Player: Excellent communication and collaboration skills; experience working in an Agile/Scrum environment.
