$135,000 - $168,000 USD yearly
Support strategic datacenter and AI accounts using digital multiphase power controllers and SIMPLIS simulation.
Originally posted 2 November 2026 by the employer.
About the role
The Senior Field Applications Engineer supports strategic customers across datacenter, AI, server, and advanced computing markets. The position focuses on digital multiphase power solutions, power modules, and server-class power delivery architectures.
What you'll do
- Serve as the technical interface for customer accounts, supporting power architecture and voltage regulator engagements from design through production.
- Provide technical guidance on digital multiphase power controllers, schematic reviews, layout reviews, board bring-up, and validation.
- Perform voltage regulator simulations with application-specific PDNs in SIMPLIS for early risk reduction and design reviews.
- Execute validation of multiphase power solutions for datacenter and AI platforms, evaluating transient response, efficiency, telemetry, and fault behavior.
- Diagnose complex electrical issues using oscilloscopes, electronic loads, current probes, network analyzers, and power supplies.
- Collaborate with Sales, Product Line, Marketing, and engineering teams to support customer engagements, milestones, and design wins.
What you'll need
- BS or MS in Electrical Engineering or related field.
- 5+ years of experience in power electronics, voltage regulator validation, power applications, or system-level power architecture.
- Hands-on experience with bench-level electrical testing and debug methodologies.
- Working knowledge of oscilloscopes, function generators, electronic loads, power supplies, current probes, and soldering tools.
- Experience resolving customer technical issues through structured debug and root cause analysis.
- Ability to manage multiple concurrent technical activities and communicate effectively across engineering and customer teams.
Nice to have
- Experience supporting AI, ML, CPU, GPU, or server power delivery applications.
- Hands-on experience with multiphase buck converters and digital VR controllers, high-current server or AI power designs, and the SIMPLIS simulation environment.
- Familiarity with validation planning, test automation, and lab instrumentation workflows.
- Experience working directly with strategic customers in a field applications, systems, or product applications role.
