Job DescriptionJob Summary:The Sr Engineer, Electronic Sustaining is a highly skilled technical contributor responsible for ensuring the long-term performance, reliability, manufacturability, and lifecycle continuity of Masimo's electronic circuit board assemblies. This role independently executes complex sustaining engineering activities across multiple product families, including advanced component obsolescence management, verification carrier design, deep-dive root-cause analysis, and cross-functional problem resolution. The Senior Engineer works closely with Hardware Design, Manufacturing Engineering, Quality, Supply Chain, and external suppliers to resolve issues, drive technical improvements, and ensure ongoing product availability and regulatory compliance. This position operates with substantial autonomy and applies advanced engineering judgment to sustain Masimo's high standards for safety, quality, and performance.
Duties & Responsibilities: - Independently perform advanced qualification of alternate components for end-of-life, obsolescence, and logistical constraints, including risk analysis and validation planning.
- Design and develop complex engineering bench verification carriers with minimal direction.
- Conduct sophisticated diagnostic, troubleshooting, and root-cause analysis on electronic circuits spanning multiple product platforms.
- Provide expert technical support for cross-functional teams requiring deep electronics expertise (without mentoring or leading others).
- Identify, evaluate, and execute significant cost-reduction and yield-improvement opportunities using data-driven approaches.
- Independently interface with contract manufacturers to resolve high-impact production or quality issues.
- Develop clear and thorough technical documentation, including test procedures, test reports, and ECO-related materials.
- Manage multiple sustaining engineering assignments simultaneously, ensuring high-quality technical outcomes with minimal oversight.
- Apply advanced DFM/DFT principles to optimize board manufacturability and reliability.
Minimum Qualifications: - 5-8+ years of experience in electronic sustaining engineering, hardware engineering, or related discipline.
- Advanced knowledge of electronic components, circuit behavior, and board-level architecture.
- Demonstrated ability to independently perform complex troubleshooting and root-cause analysis.
- Strong proficiency in schematic entry and PCB layout tools (Siemens, OrCAD, Mentor Graphics, or similar).
- Advanced ability to interpret design intent from schematics, Gerber files, requirements, and technical specifications.
- Skilled in designing and executing electronic test procedures and writing detailed technical reports.
- Strong verbal and written communication skills appropriate for documenting findings and collaborating with cross-functional partners.
- Proficient with electronic measurement equipment (oscilloscopes, spectrum analyzers, network analyzers, digital multimeters, etc.).
- Ability to work onsite Monday - Friday in Irvine, CA.
Preferred Qualifications: - Experience independently driving DFM/DFT improvements with contract manufacturers.
- Strong hands-on experience with soldering, rework, and component-level troubleshooting.
- Familiarity with EMC/EMI analysis or testing methodologies.
- Experience working in regulated industries (ISO 13485, IEC 60601, FDA design controls).
- Experience supporting multiple products simultaneously or handling high-complexity boards.
- MS in Electrical Engineering preferred (optional but common for Senior IC roles).
Education: - BS Degree in Electrical Engineering, Electronic Engineering, Engineering Physics degree or equivalent.
Compensation: The anticipated range for this position is $110,000 - $130,000. Actual placement within the range is dependent on multiple factors, including but not limited to skills, education, and experience.
