About the job
As a Power Engineer, you will own end-to-end power architecture for Aria’s data center Ethernet switch platforms, from front-end AC/DC bulk supply through board-level power delivery networks. You will solve the core challenges of delivering clean, high-density power to next-generation switching ASICs while meeting thermal, regulatory, and reliability constraints in 1U/2U form factors. This role drives vendor management, DVT execution, and PMBus/I2C telemetry and control scheme definition and validation. Scope spans concept through first customer ship and sustaining engineering.
Responsibilities
Own end-to-end power architecture for Aria’s switch platforms, defining system-level power budgets, topologies, and sequencing from front-end AC/DC bulk supply through point-of-load delivery
Specify, source, and qualify front-end bulk AC/DC power supplies, including design review, development oversight, and regulatory compliance coordination with vendors
Design and validate board-level discrete analog and digital power supply circuits for high-current, high-density switching ASIC applications
Define and implement PMBus and I2C-based power telemetry and control schemes, including fault management, margining, and real-time monitoring
Lead electrical design verification testing (DVT) for switch and router systems, covering power sequencing, transient response, efficiency, and fault scenarios
Manage power supply vendors through full development cycles, including design reviews, qualification testing, and regulatory certification (UL, CE, 80 Plus, etc.)
Partner with thermal engineering to optimize power delivery layout, loss budgets, and airflow constraints within dense 1U/2U chassis
Support hardware through first customer ship and into sustaining, driving root cause analysis and corrective action on power-related field issues
Qualifications
BS/MS in Electrical Engineering and 8+ years of experience in power architecture and design for networking switches or data center hardware
Hands-on experience with front-end bulk AC/DC power supply specification, architecture, design, and test
Proven board-level discrete analog and digital power supply design skills, including magnetics selection, layout review, and lab validation
Direct experience with PMBus and I2C-based power telemetry and control, including register-level configuration and fault handling
Track record of managing power supply vendors through design, development, testing, and regulatory compliance
Experience executing electrical DVT on networking switch or router systems, including test plan development and sign-off
Experience with combined thermal and electrical DVT on high-density networking platforms is a significant plus
Familiarity with OCP power specifications and rack-level power delivery standards preferred
Prior hands-on work on high-density 1U/2U switch or router platforms is a significant plus
