Responsibilities
- Balance new product development and sustaining engineering priorities to support innovation while ensuring strong performance of released products
- Partner with cross-functional teams (engineering, manufacturing, quality, purchasing, and vendors) to define requirements, solve technical issues, release designs, and improve product reliability
- New product development (≈50%)
- Participate in R&D efforts including feasibility studies, architecture decisions, design reviews, prototype builds, validation, and product release planning
- Translate product requirements into electrical system designs for instrumentation and flow measurement products
- Design across analog and digital circuitry, microcontrollers, communications interfaces, sensing, signal conditioning, and power systems
- Perform schematic capture and provide input for PCB/PCA design, including design-for-manufacturing (DFM) and design-for-test (DFT) considerations
- Develop and test breadboards, prototypes, and proof-of-concept circuits to validate designs and reduce technical risk
- Plan and execute electrical verification and validation testing, including hardware/firmware interaction, communications, and environmental performance
- Support regulatory and compliance efforts (EMC/CE, safety, certifications), including pre-compliance testing and design updates
- Create and maintain engineering documentation such as BOMs, schematics, PCB files, drawings, test procedures, and design records
- Sustaining engineering
- Provide electrical engineering support for released products, including production builds, customer issues, field returns, and service needs
- Troubleshoot issues across component, circuit, PCA, product, and system levels, including hardware, firmware, and software interactions
- Investigate production test failures, customer returns, and reliability issues using structured root-cause and corrective action methods
- Evaluate alternative components, obsolescence (EOL), supply chain challenges, and cost-reduction opportunities while maintaining product performance and compliance
- Design, maintain, and improve PCA test fixtures, production test methods, troubleshooting guides, and manufacturing documentation
- Implement engineering changes (ECO/ECN), including updates to schematics, PCB/PCA designs, BOMs, and work instructions
- Coordinate product changes and releases with manufacturing and production teams
- Collaborate with manufacturing, quality, purchasing, and vendors to resolve issues, improve yield, reduce rework, and sustain long-term product availability
Required qualifications
- 2–4 years of electrical engineering experience in instrumentation, industrial electronics, or similar product environments
- Experience with schematic capture and support of PCB/PCA design, including layout reviews and production documentation

- Ability to support both new product development and sustaining engineering, including prototyping, testing, troubleshooting, and engineering changes
- Experience with PCA test fixtures, production testing, and failure analysis
- Hands-on skills including soldering, rework, breadboarding, and lab equipment use
- Strong troubleshooting skills at the component level with clear documentation of root cause and corrective actions
- Familiarity with BOMs, drawings, ECO/ECN processes, and manufacturing workflows
- Proficient with Microsoft Office and engineering documentation tools
- Other duties as assigned
This role is based on-site and requires regular work across both our Marina and Monterey, CA locations.
Preferred qualifications
- Experience with Altium Designer and PADS
- Familiarity with EMC/CE design practices, including compliance, pre-compliance evaluation, and certification testing
