Product Functional Test Mechanical Technician

We are looking for a talented Product Functional Test Mechanical Technician to join the ATC Engineering team at CumminsStamford, United Kingdom.

This is a permanent role working fully onsite - primarily will be day shift however moving to mid shift so full flexible will be required

In this role, you will make an impact in the following ways:

• Verify and Validate Test Data by reviewing live and historical Genset/ Alternator parameters, confirming data accuracy, completeness, and compliance with approval requirements.

• Approve Test Results by evaluating key engine performance parameters, including speed, torque, power output, fuel consumption, temperatures, and pressures, using approved diagnostic tools and software.

• Troubleshoot Technical Issues by identifying data inconsistencies, abnormal behaviors, and test anomalies, providing immediate guidance or escalating complex issues to specialist teams when necessary.

• Coordinate Cross-Functional Support by working closely with engineers and rigging teams to resolve issues, minimise test downtime, and support approvals.

• Support with maintenance activities for Genset and Alternator test cell activities

• Drive Data Quality Improvements by tracking and analyzing recurring data discrepancies, generating summary reports, supporting corrective actions, and contributing to continuous improvement of test processes and standard operating procedures.

• Promote Safe and Efficient Testing by ensuring test procedures are followed, identifying potential safety risks from abnormal engine behavior, recommending immediate test shutdowns when critical issues are detected, and maintaining flexibility to support operations across rotating shift patterns.

To be successful in this role you will need the following:

• Demonstrated experience working in a genset test cell environment, with a strong understanding of internal Genset Sets, Engine and Alternator control systems, HHP engine performance parameters, and troubleshooting techniques.
• Strong analytical and problem-solving skills, with the ability to interpret complex test data, manage multiple sources of information, and make timely, high-quality technical decisions.
• Effective communication skills, with the ability to provide clear technical guidance, collaborate with cross-functional teams, and communicate confidently with technicians, engineers, and stakeholders.
• Results-driven and action-oriented mindset, capable of responding quickly to technical challenges, working under pressure, and consistently delivering accurate, timely outcomes.
• Commitment to health and safety, demonstrating proactive behaviors by identifying risks, following safe working practices, and contributing to a culture of continuous safety improvement.
• Ability to manage complexity and drive continuous improvement, using technical knowledge and data insights to resolve issues, improve test quality, and support efficient engine validation and approval processes.
• A good level of understanding of Cummins genset control systems, including Power Command Control (PCC) and Calterm, would be advantageous. Familiarity with Siemens programmable logic controllers and SIMATIC software, including basic system monitoring, diagnostics and fault-finding, would also be beneficial.
• The role will additionally support test-cell activities for Cummins Generator Technologies Stamford alternator development programmes at the same site. An understanding of electrical rotating machines, particularly alternators and their associated excitation, regulation and mechanical systems, would therefore be required

Education/ Experience:

• High school diploma, certificate of completion of secondary education or equivalent experience in an appropriate STEM field is required.
• HNC/HND or relevant engineering qualifications
• Requires significant relevant work experience or specialized skills obtained through education, training or on-the-job experience.
