Job description

As a Sr. SLT (System Level Test) engineer, this role will be responsible for building SLT program to enable HVM shipment of our Silicon.

Test Development & Execution
- Develop SLT test programs, scripts, and automation for new products.
- Design and implement test hardware (board, socket, ATC) and fixture solutions for SLT platforms.
- Integrate system boards, peripherals, and interface cards for test setups.
Product Characterization
- Characterize device performance at system level across operating conditions and temperatures.
- Debug test failures to determine root cause—distinguishing between product, test setup, and software issues.
- Conduct ATE to SLT correlation to implement voltage guardbands.
Process & Quality Improvement
- Collaborate with DFT, validation, and product engineering teams to improve test coverage and efficiency.
- Optimize test time and throughput for high-volume manufacturing.
- Support yield analysis, test data correlation, and defect screening strategies.
Manufacturing Support
- Transfer SLT solutions from engineering to production.
- Train manufacturing test operators and technicians.
- Provide on-site and remote support to resolve production test issues.

Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field (Master’s preferred).
8-10 years of experience in semiconductor SLT, validation, or ATE test engineering.
Strong knowledge of system-level hardware architecture (CPU, memory, I/O, power).
Proficiency in scripting languages (Python, Perl, or similar) for test automation.
Hands-on experience with SLT platforms (e.g., HonTech / Chroma, Advantest Etc.).
Experience in debugging hardware/software interface issues.
Understanding of manufacturing test flows and yield analysis.
