Job Overview

The Senior Reliability Test Engineer will define, execute, and own reliability and qualification testing for hyperscale networking platforms. This role ensures hardware meets stringent reliability, environmental, and lifecycle requirements before mass deployment across global data centers.
This position requires strong hands-on testing experience, failure analysis skills, and close collaboration with design and manufacturing teams.

Key Responsibilities:

•    Define and execute reliability and qualification test plans for networking and data center hardware.
•    Lead Robustness Validation - extended stress testing aligned to hyperscale requirements.
•    Execute environmental and mechanical testing:
o    Thermal cycling and thermal shock
o    High temperature operating life (HTOL)
o    Vibration, shock, drop
o    Humidity, corrosion, ESD
•    Test Setup Preparation: Prepare test setups, including soldering, wiring harness assembly, and integration of Devices Under Test (DUTs) into fixtures, ensuring adherence to test procedures and standards.
•    GR&R Assessments: Perform Gauge Repeatability and Reproducibility (GR&R) studies on test systems to verify reliability and ensure accurate, consistent data generation.
•    Equipment Proficiency: Utilize and understand the operation of essential test equipment, including power supplies, oscilloscopes, multimeters, function generators, and environmental chambers.
•    Testing Execution: Conduct functional, performance, and reliability tests on products in accordance with established test procedures, ensuring comprehensive evaluation.
•    Perform failure analysis, root cause investigations, and corrective action tracking.
•    Generate qualification reports, reliability summaries, and release documentation -  Provide clear and concise reports on test outcomes, actively participating in team meetings to discuss results and insights.
•    SOP Development: Develop and maintain Standard Operating Procedures (SOPs) to standardize testing processes and ensure compliance.
•    Work closely with DFR, hardware design, manufacturing, and quality teams.
•    Support launch readiness, customer qualifications, and audits.
•    Data Recording and Analysis: Accurately record and analyze test results, documenting any deviations or issues encountered during testing for future reference and troubleshooting.
•    Cross-Functional Collaboration: Work closely with design engineers and cross-functional team members to identify and resolve technical problems encountered during testing.
 

Mandatory & Good to have Skills:

•    Bachelor’s or Master’s degree in electrical / Electronics / Mechanical Engineering.
•    8+ years of experience in reliability or qualification testing for hardware systems.
•    Strong hands-on experience with:
•    Environmental chambers (thermal, humidity)
•    Mechanical stress testing (vibration, shock)
•    HALT / HASS methodologies
•    Working knowledge of:
•    JEDEC, IEC, MIL-STD, Telcordia standards
•    Proven experience in failure analysis and hardware debugging.
•    Strong documentation, reporting, and cross-team communication skills

Nice to Have 

•    Experience with network switches, routers, optics, or server platforms.
•    Familiarity with test automation, scripting, or data analytics.
•    Exposure to field reliability data (FRACAS, RMA analysis).
•    Experience working with hyperscale customers or large-scale deployments.
•    Knowledge of DFMEA / PFMEA processes.
