Manage the scheduling and execution of all testing activities, ensuring the timely completion of projects and the efficient utilization of lab resources and personnel.
Oversee the setup, calibration, and routine maintenance of all test equipment and instrumentation to guarantee the accuracy and reliability of test results.
Analyze complex test data, identify performance trends and anomalies, and generate detailed test reports with findings, conclusions, and actionable recommendations.
Collaborate closely with design, R&D, and manufacturing teams to troubleshoot product failures, identify root causes, and implement robust corrective and preventive actions.
Provide technical guidance, hands-on training, and professional mentorship to the test team, fostering a culture of continuous learning and improvement.
Ensure all testing activities and documentation strictly comply with relevant industry standards, safety regulations, and the company's Quality Management System (e.g., ISO 9001, AS9100).
Manage the test lab budget, including the procurement of new equipment and consumables, while actively controlling operational costs and seeking efficiencies.
Lead daily team huddles and planning meetings to establish priorities, review project progress, and proactively address any roadblocks faced by the team.
Evaluate and recommend new testing technologies, automation tools, and advanced methodologies to enhance test efficiency, coverage, and overall effectiveness.
Serve as the primary technical point of contact for all matters related to product testing, effectively communicating status, risks, and results to project managers and senior leadership.
Conduct performance reviews, establish clear individual and team goals, and manage the career development path for all direct reports within the test department.
Drive the development and implementation of automated test scripts and fixtures to improve test repeatability, increase throughput, and reduce manual testing efforts.
Lead formal failure analysis investigations using structured problem-solving methodologies like 8D or 5 Whys to determine the fundamental root cause of product non-conformance.
Maintain a safe, clean, and highly organized work environment within the test lab, rigorously enforcing all safety protocols and procedures for personnel.
Coordinate with external test houses and certification bodies for specialized testing, compliance verification, and third-party validation efforts.
Develop, track, and report on key performance indicators (KPIs) for the test team, such as test cycle time, first pass yield, and defect escape rates.
Review and provide critical input on Engineering Change Orders (ECOs) and product deviations to assess their impact on testing and product validation.
Champion a quality-first mindset throughout the organization by clearly communicating the value and impact of rigorous testing on product reliability and customer satisfaction.
Ensure the meticulous documentation and secure archiving of all test procedures, raw data, final reports, and equipment calibration records per company and regulatory policies.
Lead the design and fabrication of custom test fixtures and harnesses required for new product introductions and specialized test setups.

Secondary Functions

Represent the test department in cross-functional project meetings, design reviews, and phase-gate approvals.
Assist in the development and ongoing management of the department's annual operating budget and capital expenditure plans.
