Senior Engineer - Power Device Electronics

About our group:

Working in tandem with world class silicon suppliers, the Power Device team develops custom mixed signal integrated circuits that are fundamental to HDD operation and incorporate an array of embedded functions including motor drive, voltage regulation, energy harvesting and data conversion. The Power Device team is a small group that resides within the larger Hardware Engineering organization, which has responsibility for many aspects of HDD design. As such, ample opportunity exists for cross pollination and skill development via collaboration with subject matter experts across multiple functional disciplines

About the role - you will:

Work on a variety of projects including silicon development and design / verification of power distribution systems for HDD products.

Participate in silicon development activities centering on the specification, design and validation of full custom integrated power electronics including three-phase motor drivers, data converters and voltage regulators.

Conduct behavioral level modeling and design to help guide vendor efforts. In this capacity, examples include:

• • Defining gain bandwidth product requirements for op-amp circuits
  • Identifying appropriate switching regulator parameters (switch ON resistance, switching frequency, etc.)

Shift focus to component level testing when silicon becomes available, with the bulk of specified device parameters validated in the lab.

Work closely with other functional teams to integrate silicon into Seagate end products.

Own voltage budgeting, which is a detail-oriented process whereby an entire power distribution system consisting of voltage regulators, printed circuit board and receiving electronics is simulated to ensure critical voltage constraints will be satisfied in volume production.

• • Collaborate with stakeholders to identify requirements and generate system level models.
  • Perform simulations to highlight issues and potential areas for improvement, with models and assumptions iteratively adjusted until all requirements are satisfied.

About you:

• The ideal candidate for this position is self-motivated and will exercise discretion in determining methods and procedures for accomplishing assigned objectives, all while operating with minimal direction and oversight.
• A demonstrated ability to work effectively with cross functional teams and network with key contacts outside your own area of expertise is mandatory.
• Through the course of launching new silicon to production, you will interface with individuals of diverse backgrounds and experience levels, and the ability to adopt situational teaching and learning roles is crucial.

Your experience includes:

Electronics development with mixed signal background and familiarity in following areas:

Voltage regulators

Op-amp circuits

Transconductance loops

D/A and A/D converters

Spice circuit modeling

• • Using behavioral Spice constructs to create abstracted sub-circuits.
  • Constructing system level models to predict performance.

Bench level electronics validation with hands on knowledge of common test equipment (power supply, oscilloscope, function generator, network analyzer, etc.)

Demonstrated ability to prepare comprehensive documentation and presentations using Microsoft tool suite (Excel, Word, PowerPoint, Visio)

Strong written and verbal communication skills.

Bachelor’s degree in electrical engineering with 5-8  years of experience, or Master’s degree with 2-4 years of experience, or PHD with 0-2 years of experience.

You might also have:

Deeper knowledge of electronics development including

• • System level offset & noise analysis
  • Measurement of common mode rejection and power supply rejection
  • Circuit stability modeling and verification
  • Motor drive principles

Voltage regulator modeling to determine stability and predict transient response

Additional bench level experience

• • Validating op-amp circuit parameters
  • Quantifying voltage regulator performance including efficiency and line / load regulation.
  • Noise measurements

Filter analysis & design

Control systems

PCB design

Low voltage power distribution systems
