Nice To Haves

Familiarity with radiation-hardened or radiation-tolerant IC concepts (QMLV, QMLP, SEP ratings)
Proficiency with power electronics characterization techniques: Bode plot (AC sweep) for gain margin and phase margin, output noise density, startup and shutdown waveforms, transient response including load step and line step, and PSRR
Advanced: experience with CMTI testing and double pulse testing (DPT) for GaN and wide-bandgap device characterization
Ability to establish strong relationships with key stakeholders critical to success, both internally and externally
Strong verbal and written communication skills
Demonstrated strong interpersonal, analytical, and problem-solving skills
Ability to work in teams and collaborate effectively with people in different functions
Ability to take the initiative and drive for results
Strong time management skills that enable on-time project delivery

Responsibilities

Ensure the product meets its specifications as defined in the datasheet and VVCM.
Ensure device functionality is understood and correlated across system-level use-cases and break-the-part test conditions.
Characterize the boundaries of device operation and document behavior at and beyond rated limits.
Design PCB boards and develop automation software to increase coverage and reduce data collection time.
Own validation and characterization activities across radiation-hardened and radiation-tolerant power products.
Work with the product definition and design team before silicon availability to understand validation requirements.
Define and own a validation plan and schedule with coverage of all use-cases and corner conditions.
Develop and maintain a VVCM/Starfish compliance matrix to track validation coverage and drive closure of all datasheet limits.
Design and build validation PCBs using Altium Designer and/or Cadence Allegro X.
Develop reusable, automated test sequences using Python and NI TestStand to execute the validation plan and collect parametric characterization data.
Support COTS upscreen validation checkout.
Perform datasheet plot collection and creation; apply statistical analysis to assess spec margins and drive datasheet limit decisions.
Drive reviews with the extended team covering validation boards, test results, and debug findings.
Perform debug through design of experiments on anomalous behavior.
