Senior Test Engineer – Semiconductor Industry

📍 Location: Orange County, CA |💲 $150,000–$180,000 Base Salary+ Profit Sharing Plan

Are you a driven Test Engineer with a passion for precision and performance? Join a leading engineering team developing high-performance mixed-signal semiconductor products for avionics applications. This is your opportunity to lead the test strategy, drive hardware and software test development, and collaborate with cross-functional teams across the entire product lifecycle.

What You'll Do

• Lead the transition of test solutions from legacy systems to advanced ATE platforms.
• Design and implement high-speed test solutions at both the wafer and package level.
• Develop test hardware (DUT boards, load boards, power distribution networks) and write robust test programs in C++/Linux.
• Collaborate with design teams to incorporate Design for Test (DFT) methodologies early in the development cycle.
• Analyze test yields and production data to identify areas for optimization and cost savings.
• Assist in long-term capital equipment planning and tool selection.
• Conduct reliability and qualification testing, and support ATE characterization.
• Provide technical support to internal and external customers, and contribute to overall product robustness.
• Manage multiple test development projects simultaneously while maintaining top-tier quality standards.

Qualifications

• BS/MS in Electrical Engineering
• 5+ years of experience in semiconductor test engineering, ideally in mixed-signal or avionics domains.
• Strong hands-on experience with ATE platforms—preferably Cohu
• Knowledge of analog/digital test development, debugging, and characterization.
• Experience in board-level design (analog/mixed-signal/digital PCBs); layout knowledge is helpful but not required.
• Familiarity with life testing, qualification, and yield improvement.
• Clear, concise communicator with a collaborative mindset.
• Experience in high-reliability or safety-critical applications is a strong plus.
