Senior Analog & Power Validation Engineer - Camera & Laser Sensor Systems
AppleHerzliya, Tel Aviv District, IsraelSenior7+ years
Apply Apple's Hardware group is home to some of the world's most advanced technologies - powering the experiences that define Apple products.
We are looking for a highly skilled Senior Analog & Power Validation Engineer — Camera & Laser Sensor Systems to join our team in Herzliya.
- Lead the validation and characterization of analog and power domains for camera and laser sensor subsystems
- Perform detailed power consumption analysis across all system operating modes — active, standby, sleep, and transition states
- Characterize laser drive circuits — including drive current profiles, modulation behavior, thermal effects, and compliance voltage margins
- Validate protection circuits — over-current, over-voltage, under-voltage lockout (UVLO), thermal shutdown, and eye-safety interlock mechanisms
- Verify power sequencing, ramp rates, and domain interdependencies across complex multi-rail systems
- Define and implement DFV strategies for table-top development boards, ensuring comprehensive observability and controllability of critical analog and power nodes
- Specify test point placement, measurement access, load emulation provisions, and fault injection capabilities at the board design stage
- Collaborate with hardware design teams to influence board architecture for optimal validation coverage
- Document DFV requirements and guidelines as part of the development platform specification
- Validate system behavior across all defined operating modes and transitions
- Characterize power efficiency, conversion losses, and thermal performance of power delivery networks
- Perform parametric characterization — voltage accuracy, ripple, transient response, load regulation, and line regulation
- Execute corner-case and stress testing to identify margins and failure boundaries
- Support research and physics evaluation activities with custom measurement setups and data acquisition
- Provide analog/power expertise for experimental configurations and prototype evaluation
- Design and execute targeted characterization campaigns in support of new technology investigations
- BSc in Electrical Engineering, Electronics Engineering, or a related field
- 7+ years of experience in analog/power validation, characterization, or hardware design verification
- Strong Python proficiency — automation, instrumentation control, data analysis, and visualization
- Proven experience designing validation strategies and DFV methodologies for development platforms
- Hands-on experience with power domain characterization in multi-sensor systems
- Demonstrated ability to work across the full validation cycle — from test plan definition through execution, analysis, and reporting
- Solid understanding of laser safety standards and protection circuit requirements
- Strong system-level vision — ability to understand the full power architecture and how analog domains interact within the broader camera and laser sensor system
- System-to-component depth — proven capability to conduct system-level power validation while diving to component-level characterization for root-cause analysis and margin assessment
- Deep knowledge of power management architectures — LDOs, DC-DC converters (buck, boost, buck-boost), charge pumps, and power switches
- Hands-on experience with laser driver circuits — current sources, pulsed drive, modulation schemes, and safety mechanisms
- Proficiency with analog test instrumentation — oscilloscopes, power analyzers, source-measure units (SMUs), electronic loads, spectrum analyzers, and thermal imaging
- Experience with DFV/DFT methodologies for analog and mixed-signal systems
- Strong proficiency in Python for test automation, data acquisition, instrumentation control, and analysis
- Understanding of PCB design considerations for power integrity — layout, decoupling, grounding, and thermal management
- MSc in Electrical Engineering, Power Electronics, or a related discipline — considered a significant advantage
- Experience with camera sensor power domains (AVDD, DVDD, IOVDD) and associated sequencing requirements
- Familiarity with VCSEL or edge-emitting laser driver characterization
- Experience with thermal characterization and power derating analysis
- Background in EMC/EMI considerations for analog and power circuits
