Diagnostic Engineer

Job Description:

We are seeking a Diagnostics Engineer to join an advanced automotive engineering team focused on climate control systems, vehicle diagnostics, and service/manufacturing support. This role is ideal for someone with strong experience in UDS, OBD-II, CAN, LIN, FlexRay, Ethernet, DFMEA, fault detection, and diagnostic strategy development.

As a Diagnostics Engineer, you will develop, validate, and optimise diagnostic routines, fault detection methods, health-check strategies, and system logic for climate/HVAC domain systems. You will collaborate with cross-functional engineering teams to ensure robust diagnostic coverage across hardware and software changes, supporting both manufacturing and global service operations.

Key Responsibilities

• Develop and validate diagnostic strategies for climate/HVAC systems.
• Conduct system logic reviews, DFMEA, failure analysis, and create corrective actions.
• Lead root-cause investigations and produce technical diagnostic documentation.
• Design and validate health-check routines for vehicle electronic systems.
• Work with CAN, LIN, FlexRay, Ethernet and other in-vehicle network protocols.
• Use diagnostic tools and platforms such as TOPIX, MSOSA, or equivalent.
• Support service engineering teams with diagnostic guidelines and serviceability improvements.

Key Skills Required

• Automotive diagnostics engineering (service or manufacturing).
• Strong understanding of UDS, OBD-II, fault detection and diagnostic communication.
• Knowledge of vehicle electrical networks and embedded system behaviour.
• Experience with DFMEA, failure analysis, and system design logic.
• Ability to produce clear technical documentation and diagnostic workflows.
• Background in climate/HVAC systems is highly desirable.

This role offers the opportunity to influence diagnostic quality, serviceability, and vehicle performance across major automotive programmes.
