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 Change the world. Love your job. Designers bring semiconductors to life by defining, developing and/or modifying analog and mixed signal electronic parts, components, or integrated circuitry. They work with other designers and the broader R&D and demand creation teams to align on approaches and parameters for a given device, creating block level specifications for the designs. They take the designs through the concept, implementation in schematic and supervising layout, followed by tape out to the fab. They also support silicon validation, test, qualification for reliability, and finally ramp to mass production. Designers also conduct tests and analyze data to ensure the chosen methods are optimal for the defined specifications and reliability requirements. Minimum requirements: • 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 Preferred qualifications: • 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 Leadership qualifications • 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
