Senior Staff Applications Engineer - Austin, United States
Originally posted 14 September 2026 by the employer. Relisted by the employer on 30 September 2026.
Design multiphase power solutions for AI and cloud infrastructure products.
About the role
As a Senior Staff Applications Engineer, you will support pre-silicon new feature bring-up and tapeout validation for AI and cloud infrastructure products within the power management team. This role involves working with digital multiphase PWM controllers and Smart Power Stages.
What you'll do
- Design multiphase power solutions for CPU/GPU/ASIC-class loads using digital multiphase controllers and Smart Power Stages.
- Develop EVBs, including schematic capture, component selection, and thermal design.
- Oversee PCB layout for CPU/GPU-class boards to meet power delivery requirements, including current density, copper allocation, sensing, PDN, and thermal performance.
- Design and review high-speed digital routing, including differential clock and data pairs with controlled impedance and high-speed single-ended signals.
- Validate power performance in the lab (load transient, efficiency, sequencing, protection, telemetry) and signal quality using oscilloscopes, VNAs, and TDRs.
- Support pre-silicon new feature bring-up and tapeout validation, debugging and closing issues with IC design and firmware engineering.
What you'll need
- Bachelor's or Master's degree in Electrical Engineering or related field.
- 10+ years of relevant experience in power design for CPU/GPU/ASIC-class loads, including multiphase DC/DC converters and digital power management products.
- Experience with high-speed digital interfaces, including high-speed differential clock and data interfaces (SerDes-class) and high-speed single-ended routing (such as DDR).
- Strong lab skills with high-bandwidth instruments (scopes, VNAs, TDRs), power validation equipment, measurement-simulation correlation, and fixture/probing design.
- Demonstrated leadership in cross-functional design reviews and clear communication of power and SI/PI concepts.
Nice to have
- Hands-on experience with SI/PI/EM tools (e.g., Ansys HFSS 3D/Layout, SIwave, Clarity, CST, Keysight ADS Momentum/Sigrity, HSPICE, HyperLynx).
- Experience designing boards that interface with pre-silicon emulation platforms.
- Track record of bringing complex high-speed hardware from concept to production, including multiple design spins and volume manufacturing support.
- Experience with AVSBUS, SVID, SVI3, and PWM VID control bus architectures.
- Experience with high-speed differential clock and data interfaces such as PCIe, Ethernet, and USB, and high-speed single-ended interfaces such as DDR memory.
