• Hands-on experience designing for EMC and debugging associated issues
• Strong skills in power management and low-power optimization
• Extensive on-site factory experience with contract manufacturers
• BS or MS in electrical engineering or related field
• Experience with electrical simulation (i.e. SPICE, electro-magnetic, etc.)

Even Better:

• Experience in board-level analog design
• Familiarity with Altium Designer
• Experience with ARM processors
• Understanding of near-field and RF design fundamentals (i.e. NFC, Wi-Fi, Bluetooth, etc)
