As a Senior PCBA Test Engineer at MKS, you will partner closely with Engineering, Supply Chain, Contract Manufacturing partners, and internal stakeholders to design, develop, deploy, and support automated PCB assembly (PCBA) test systems used in high‑volume production environments. In this role, you will serve as both a development engineer and frontline technical expert, ensuring robust, repeatable test solutions that meet product quality, delivery, and customer requirements. You will report to the Manager, Test Engineering.

You Will Make an Impact By:

• Designing, developing, and documenting automated PCBA test systems, including hardware, software, and mechanical fixtures, for deployment at global contract manufacturing sites
• Developing and supporting automated test applications using NI LabVIEW and TestStand, including user‑friendly GUIs and test report generation
• Working with PCBA contract manufacturers to implement AOI, ICT, and FCT to improve production yield and reduce PCBA rejection and scrap rates
• Performing verification and validation of duplicate automated test systems prior to release to contract manufacturers
• Troubleshooting Unit Under Test (UUT) failures, test system anomalies, and identifying opportunities for continuous improvement
• Analyzing test data using statistical process control (SPC) tools to improve yield and product quality
• Providing frontline technical support and remote assistance, including use of virtual/augmented reality tools, to support technician training and issue resolution across multiple time zones

Skills You Bring:

• Bachelor of Science in Electrical Engineering is required; Master of Science in Electrical Engineering is preferred
• 8+ years of experience developing PCBA functional test programs (hardware and software), ideally in a high‑volume manufacturing environment
• Experience with NI LabVIEW and NI TestStand; CLD (Certified LabVIEW Developer) preferred
• Ability to read electrical schematics and create wiring diagrams; experience using tools such as PADS and Visio
• Expertise in PCBA quality screening, test coverage analysis, and manufacturing defect detection utilizing AOI, X-Ray, Flying Probe, ICT, Boundary Scan, Functional Test, and statistical quality methodologies
• Hands‑on experience with laboratory test equipment, including multimeters, oscilloscopes, power supplies, waveform generators, and DAQ devices
• Experience writing and reviewing test specifications and procedures
• Strong project planning skills with the ability to manage multiple efforts simultaneously in a fast‑paced environment

Preferred Skills (Optional):

• Familiarity with low‑noise analog and high‑speed digital PCB designs
• Exposure to DFT (Design for Test) and DFM (Design for Manufacturing) principles
• Experience analyzing test data using statistical tools such as Minitab
• Vendor management or external design partner coordination experience

Supervisory Scope (Optional):

• Reporting Relationships: Individual contributor role
• Financial Responsibilities: None

Physical Demands and Working Conditions:

• Ability to work in laboratory and manufacturing environments
• Occasional lifting of test fixtures and equipment
• Use of standard laboratory tools and computer‑based development environments
• Ability to support off‑hour troubleshooting calls as needed to support global manufacturing operations

Compensation and Benefits:
Salary Pay Range: $90,000.00 - $147,000.00 per year. This range is a good faith estimate of the expected salary range for this position, based on a wide range of factors including qualifications, experience and training, operational and business needs and other considerations permitted by law.    At MKS, it is not typical for an individual to be hired at or near the top of the range for the role.

Bonus: This position is eligible for a discretionary annual bonus, in an amount to be determined by MKS [or as applicable]. 

Benefits: MKS offers a comprehensive benefits package, including health insurance coverage (medical, dental and vision), 401(k) with company match, life and disability insurance, 12 paid holidays, sick time, 15 paid vacation days, [6 weeks fully paid] parental leave, adoption assistance and tuition reimbursement [and for participation in any stock programs, signing bonus, etc.].
