Über diesen Job

Intro

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.
