Analog IC Design Engineer | Audio AAA

About the role

Design high-efficiency Class D power output stages for automotive and consumer audio amplifier products. You will own the switching power path from architecture through silicon validation, including gate drivers, H-bridge and BTL output stages, dead-time control, and protection circuits in high-volume production ICs. Products include both monolithic power stages and multi-chip module GaN based solutions. 

Responsibilities

• Architect and design Class D power output stages: H-bridge and BTL configurations, gate drivers, charge pumps, level shifters, dead-time control, and shoot-through protection
• Design high-voltage switching circuits with focus on efficiency, thermal performance, and EMI compliance
• Develop transistor-level schematics in Cadence Virtuoso and verify performance across PVT corners using SPICE simulation
• Collaborate with systems, layout, and applications engineers to meet audio performance specifications (THD+N, IMD, SNR, PSRR, idle channel noise) and power delivery targets
• Analyze and resolve design issues from prototype through production qualification, including EMI/EMC characterization and LC filter optimization
• Contribute to IP reuse strategy and design methodology improvements
• Mentor junior engineers on analog design fundamentals, simulation best practices, and design-for-manufacturing techniques
• Provide technical leadership within the design team: guide design reviews, drive architecture decisions, and establish standards for schematic quality and documentation

• MS in Electrical Engineering (or equivalent)
• 5-10+ years of analog/mixed-signal IC design experience
• Demonstrated experience designing power output stages: gate drivers, H-bridge or BTL output configurations, dead-time control, and overcurrent/thermal protection
• Strong understanding of high-voltage switching behavior, GaN/MOSFET/LDMOS device physics, and parasitic-aware design techniques
• Experience with EMI mitigation in switching amplifiers (spread-spectrum modulation, slew-rate control, edge-rate optimization)
• Proficiency with Cadence Virtuoso schematic/simulation environment
• Experience taking designs from concept through tapeout and silicon bring-up

• Signal-chain design experience: delta-sigma ADCs, DACs, or PWM/PDM switching modulators for audio-band applications
• Familiarity with sampled-data circuits, loop filter design, and quantizer architectures
• Experience with automotive-qualified products (AEC-Q100)
• Publications or patents in audio IC design or Class D amplifier techniques

• Ability to establish strong relationships with key stakeholders critical to success, both internally and externally
• Ability to take ownership of everything in your world and drive solutions 
• Mentorship of Jr engineers
• Strong verbal and written communication skills
• Ability to quickly ramp on new systems and processes
• Demonstrated strong interpersonal, analytical and problem-solving skills
• Ability to work in teams and collaborate effectively with people in different functions
• Ability to take the initiative and drive for results
• Strong time management skills that enable on-time project delivery
