We are looking for an engineer to join our IoT group, focusing on manufacturing and test systems. This role will own technical operations for electronics manufacturing, overseeing the printed circuit board assembly and test processes, implementing changes for quality improvement, and working collaboratively with our internal hardware engineering and operations groups. The Principal Manufacturing Test Engineer will be responsible for the maintenance and improvement of our high-volume IoT manufacturing systems, troubleshooting product/test issues with our contract manufacturing partners, and directly contributing to the development of high-quality test systems to ensure they align with CMT’s IoT business goals. This is a key hire as it will have an enormous amount of impact and visibility, and offers a ton of growth potential.
- Provide ICT, functional and performance test engineering support to IoT Engineering and external contract manufacturer teams from new product transitions to volume manufacturing, including test station qualification/approval at the CM, initial commissioning, on-going use, debug, maintenance and calibration
- Partner with IoT Engineering to drive DFT early in the development cycle in order to formalize manufacturing test requirements for PCBAs and to ensure that test systems are aligned with the capability of the product. Optimize test solutions for efficiency, cost, and yield from NPI to product end of life
- Responsible for yield improvement for any PCBA related ICT, functional or performance tests in the manufacturing process through analysis of data from yield reports, equipment logs and product diagnostics to determine sources of yield loss
- Support and qualify hardware changes, including new components and manufacturing process changes
- Participate in engineering reviews, such as schematic, layout, and DFM, with both cross-functional teams and external engineering partners
- Develop system test plans, including test methodology and coverage to validate changes and ensure product reliability
- Create documentation such as Engineering Change Orders and general process documentation.
- Analyze PCBA process/test issue failures, perform debug processes and determine root cause as required to implement both interim containment plans and long-term corrective actions to increase PCBA performance and reliability
- Create and maintain PCBA process docs, test specs and debug procedures. Review and contribute to technical documentation (schematics, test specifications, test set layout, product testability), as required
- Complete any additional tasks that may arise
- BS in Electrical or Computer Systems Engineering, or equivalent experience
- 9+ years of direct experience in electrical hardware engineering and/or test engineering
- Subject matter expertise in manufacturing test strategy and DFT as part of new product development efforts and manufacturing transition initiatives
- Experience working with contract manufacturing partners (ODM, OEM, JDM). Knowledge of PCBA manufacturing flow (solder paste, SPI, SMT, X-Ray, AOI, etc.)
- Deep knowledge/experience of functional test HW from design, development, and validation to MP implementation
- Knowledge of the technical rigor and processes required to bring a product to market at scale.
- Experience using statistical methods and problem solving frameworks (six sigma) to facilitate root cause analysis (debug/resolve manufacturing issues)
- Proficient with database structuring and manipulation using SQL
- Basic understanding in programming techniques (e.g. C, C++, Python) and/or script writing (using Labview, Arduino, PLCs, or similar)
- Willingness to travel up to 25% to external Contract Manufacturing sites as required
- Strong interpersonal and communication skills, and the ability to work with cross-functional engineering teams
- Ability to articulate complex technical concepts to a non-technical audience
Nice to Have:
- Lean or Six Sigma certification/training
- Experience with data visualization (Tableau)
- Experience with OnShape
- Experience with Linux
- Familiarity with IPC-A-600 and IPC/WHMA-A-620
Compensation and Benefits:
- Fair and competitive salary based on skills and experience
- Equity in the form of Restricted Stock Units (RSUs)
- Medical, Dental, Vision and Life Insurance, matching 401k, short-term & long-term disability and parental leave
- Unlimited Paid Time Off including vacation, sick days & public holidays
- Flexible scheduling and work from home policy depending on role and responsibilities
- Feel great working to improve road safety around the world!
- Join one of our many employee resource groups including Black, AAPI, LGBTQIA+, Women, Book Club and Health & Wellness
- Extensive wellness, education and employee assistance programs
- CMT will do all that is possible to support our employees and create a positive and inclusive work environment for all!
