PRM Parking Management combines state-of-the-art hardware—cameras, payment terminals, barriers, access control systems, displays, traffic lights, sensors, and control units —with powerful software and cloud solutions. Our IoT systems operate reliably in the field thousands of times every day.

We are looking for aHardware Systems Engineer to join our technology and integration team. The role involves integrating, analyzing, and testing technical devices, and ensuring that our systems run smoothly and reliably at all times. Our technology includes camera systems, payment devices, IoT hardware, controllers, mobile routers, and edge devices.

Your responsibilities

Camera tests, firmware checks, and functional tests in the lab
Remote fine-tuning and optimization
Analysis of image quality, trigger behavior, and monitoring data

Hardware & IoT Integration

Integration of barriers, access control systems, sensors, control units, displays, traffic lights, and controllers via RS232/485, CAN, relays/GPIO, and TCP/IP
Optimization of signal paths and device logic
Analysis of existing customer hardware and protocols (including reverse engineering)

Payment Terminals & Ticket Vending Machines

Integration via API, SDK, or proprietary interfaces
Analysis of monitoring data, identification of systematic error patterns
Identification of sustainable improvement measures
Collaboration with Development, Support, and Engineering

On-site assignments (as needed)

Complex parking areas
Introduction of new generations of hardware
Specialized testing under real-world conditions
→ Not a traditional field service role, but on-site assignments are part of the job .

Documentation

Technical documentation of configurations, tests, and diagnostics
