Electrical Engineer Location: Santa Clara, CA (primarily onsite)
Group: Analyzer Product Group (APG), Engineering
Role SummaryWe are looking for an Electrical Engineer to design, develop, and troubleshoot custom electronics for a Cavity Ring-Down Spectroscopy (CRDS) product. You will work across analog, digital, and mixed-signal circuits, taking designs from concept through schematic/PCB layout, prototype bring-up, test/validation, and support in manufacturing.
Key ResponsibilitiesDesign & Development- Design and develop custom electronics (analog, digital, mixed-signal) for precision instrumentation and sensor systems
- Own schematic capture and PCB design (placement/routing), including BOM creation, DFM/DFT considerations, and design reviews
- Perform component selection and trade studies (cost, risk, availability, lifecycle, reliability), including derating and failure mode thinking
Board Bring-Up & Debug- Lead board bring-up: initial power checks, clocking, comms interfaces, fault isolation, and root-cause debugging
- Use lab instrumentation (oscilloscope, DMM, logic analyzer, spectrum analyzer) to characterize signals, noise, timing, and power integrity
Test & Validation- Develop test strategies and write test procedures to verify functionality, performance, reliability, and robustness
- Partner with systems, optics/laser, firmware/software, and manufacturing to troubleshoot instrument-level issues and drive corrective actions
Production Support- Support transition to production: ECOs, documentation, test fixtures support, and resolving field/manufacturing issues
Education & Experience- Bachelor's degree in Electrical Engineering (or equivalent practical experience)
- 3+ years of hands-on experience designing and debugging electronics (preferably for instrumentation, sensors, or embedded systems)
Technical Expertise- Strong fundamentals in circuit analysis and electronics: analog + digital, mixed-signal interfaces, and signal integrity basics
- Demonstrated experience with board bring-up, prototyping, soldering/rework, and hardware debugging
- Proficiency with schematic capture and PCB design tools (Altium preferred; OrCAD/KiCad acceptable)
- Comfortable using lab equipment: oscilloscope, DMM, power supplies, function generator; logic analyzer experience is a plus
Soft Skills- Strong problem-solving, documentation, and communication skills
- Able to work effectively across disciplines
Preferred Qualifications- Precision analog / low-noise design (TIA, photodiode front-ends, ADC/DAC interfaces, reference/clock design)
- Power architecture experience (switching regulators + LDOs, grounding strategy, ripple/noise control, sequencing, protection)
- Experience with embedded hardware interfaces (SPI, I2C, UART, CAN, USB, Ethernet) and supporting firmware teams during integration
- EMC/EMI and compliance awareness; experience designing for noisy environments and mixed analog/digital layouts
- Experience in regulated or high-reliability products (documentation discipline, design reviews, test coverage)
- Exposure to optoelectronics/instrumentation systems (lasers, photodetectors, analog front ends, precision timing)
The base salary range for this full-time position is $110K to $120K. Our total compensation packages includes base salary, bonus eligibility, and equity.
