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.
