Manufacturing Test Engineer – Vehicle Systems

Your Work Shapes the World at Caterpillar Inc. When you join Caterpillar, you're joining a global team who cares not just about the work we do – but also about each other. We are the makers, problem solvers, and future world builders who are creating stronger, more sustainable communities. Together, we are building a better world.

The Opportunity: Interested in working hands-on with full vehicle systems in a high-volume manufacturing environment? As a Manufacturing Test Engineer, you will play a key role in end-of-line (EOL) and functional testing, ensuring machines meet defined performance specifications across engine, hydraulic and integrated systems.

Working within a highly skilled Manufacturing Engineering team, you will support production by diagnosing test failures, improving test capability and embedding robust, repeatable processes. You’ll work closely with engineering, maintenance and operations teams to deliver reliable, high-quality products while driving continuous improvement across production systems.

As a Manufacturing Test Engineer, you are accountable for, but not limited to:

• Execute and support end-of-line (EOL) vehicle testing across engine, hydraulic and integrated systems, ensuring machines meet defined performance and quality standards.
• Diagnose and resolve test failures across vehicle systems, test equipment and control logic, acting as an escalation point to support production recovery and minimise downtime.
• Analyse test data and system outputs to validate performance and support structured root cause investigations.
• Support and maintain production test systems, ensuring reliable execution, data integrity and effective fault detection.
• Develop and implement improvements to production test processes, diagnostics and fault-finding methods to enhance robustness, repeatability and first-time pass rates.
• Support New Product Introduction (NPI) by defining test requirements, validating methods and introducing new test capability into production.
• Ensure test processes and equipment operate in line with safety, quality and environmental standards, supporting compliant and reliable manufacturing operations.

What You Can Demonstrate:

• Engineering – Manufacturing (MFG): Applies manufacturing engineering principles to support EOL testing and production systems, ensuring equipment and processes meet performance, safety and quality requirements.
• Problem Solving: Uses structured fault-finding techniques to diagnose and resolve production test failures across vehicle systems and test equipment.
• Analytical Thinking: Interprets test data, signals and system outputs to validate performance against specifications and support root cause investigations.
• Manufacturing Processes: Operates within and improves production test processes to ensure consistency, repeatability and efficient throughput.

What You May Have:

• Applies knowledge of production test systems to ensure reliable execution, maintain data integrity and improve fault detection capability within manufacturing environments.
• Demonstrates practical understanding of vehicle systems (engine, hydraulics, controls) to diagnose behaviour during test and effectively resolve system-level issues.
• Utilises structured problem-solving methodologies (e.g. 5 Why, Fishbone, 8D) to identify root causes and implement corrective actions that support production recovery and prevent recurrence.
• Contributes to New Product Introduction (NPI) by supporting the integration of new test methods and enhancing production test capability to meet evolving product requirements.

Benefits: 27 days annual leave + bank holidays, opportunity to buy additional holiday, 10% Bonus, contributory pension scheme - Caterpillar will double the employee's contribution up to 10%, contributory share scheme - Caterpillar will match 50% of the employee's contribution, Employee Support Networks – join groups that offer support, connection, and a sense of community, optional flexible benefits including access to private health and dental care plans, EV car lease etc.

Travel: Up to 5% UK travel may be required, including visits to other facilities as needed. This position requires working onsite five days a week.
