Job Title

Mechanical Testing Technician

Location

Cupertino, CA 95014 (Onsite)

Duration

6 Months Contract

Overview

We're looking for a mechanical testing technician passionate about materials characterization who will ensure Client's battery products perform exceptionally. You'll combine hands-on mechanical testing with rigorous data collection to validate material properties and measure real-world performance of thin layer materials. You'll understand not just what materials do, but how they perform under various mechanical and reliability conditions.

Key Responsibilities

Material Characterization & Hands-On Testing

• Execute comprehensive material characterization tests using specialized mechanical testing equipment
• Perform systematic stress-strain property extraction from thin layer materials used in battery products
• Design and implement test protocols for mechanical test scenarios.
• Identify and classify material properties that reveal performance characteristics and areas for improvement
• Generate detailed test reports to capture overall material performance and reliability metrics

Data Collection & Analysis

• Design, execute, and manage mechanical testing protocols that capture material behavior under real-world conditions
• Collect, organize, and validate datasets
• Analyze collected mechanical test data to surface patterns, anomalies, and performance insights
• Create detailed documentation and reports that translate technical findings

Sample Preparation & Testing Operations

• Sample Management
• Prepare test samples according to established protocols and quality standards
• Document sample preparation methodologies for reproducibility and team knowledge-sharing

Communication & Collaboration

• Collaborate with development teams to refine testing approaches and material specifications
• Communicate findings clearly—both technical results and their implications for product performance
• Contribute to test plan design and documentation that ensure product quality standards
• Deliver accurate and timely results with exceptional attention to detail

Education

BS in Mechanical Engineering or related field

Required Experience

• Minimum 1 year of proven experience with mechanical testing and reliability testing
• Hands-on experience with material characterization equipment and stress-strain testing (Instron tensile, electropulse)
