HMI Software Engineer - Kiosk Devices

We’re building the next generation of connected parcel locker systems - a greenfield IoT product that blends hardware, embedded software, and cloud services. As an HMI Software Engineer , you’ll design and deliver the interactive applications that run on our parcel lockers’ touchscreens, creating seamless, intuitive customer experiences. This is your chance to work on a product that lives in the physical world, impacts thousands of users daily, and leverages modern UI technologies (Qt/QML, or web-based frameworks) in an embedded Linux environment.

Tasks

• Design, develop, and deploy the HMI application running on parcel locker interactive screens
• Select and implement the most suitable UI technology ( Qt/QML, or Chromium/WPE-based ) to ensure performance, resilience, and maintainability
• Integrate with hardware controllers (e.g., RS-485/Modbus, TCP/IP APIs ) to manage door operations, sensors, and system health monitoring
• Interface with peripherals including barcode scanners, printers, and payment devices via USB-HID, ESC/POS, or vendor SDKs
• Ensure offline resilience to guarantee uninterrupted customer experience in case of connectivity loss
• Secure the kiosk environment by applying system hardening and lockdown practices
• Collaborate with backend/API teams, hardware engineers, and product designers to deliver a reliable, end-to-end solution

Requirements

• Strong experience developing applications for embedded Linux systems
• Proficiency with at least one HMI/kiosk framework : Qt/QML, Web stack (HTML/CSS/JS) deployed in Chromium/WPE kiosk mode, etc.
• Familiarity with containerization (Docker) and fleet management/OTA tools
• Experience integrating and troubleshooting hardware peripherals (scanners, printers, controllers)
• Understanding of system hardening and kiosk device security
• Hands-on experience with networked IoT applications , interfacing with backend APIs (REST/gRPC/GraphQL)

Bonus Points

• Experience building HMI systems for kiosks, infotainment, or industrial automation
• Exposure to large-scale device fleet deployments (hundreds or thousands of units)
• Knowledge of observability practices for IoT systems (logs, metrics, remote debugging)

Benefits

This is a greenfield opportunity to create the customer-facing experience of a connected IoT platform. You’ll work at the intersection of embedded systems and modern UI engineering , bringing physical and digital worlds together. Your work will directly shape how people interact with our parcel locker system, influencing both usability and reliability at scale.
