What are the key skills and qualifications needed to thrive in the Contamination Control Engineer position, and why are they important?

A successful Contamination Control Engineer typically holds a degree in engineering or a related scientific field and possesses expertise in contamination control protocols, cleanroom practices, and environmental monitoring. Familiarity with relevant standards (such as ISO 14644), particulate and microbial detection systems, and certification in contamination control or cleanroom operations are often essential. Excellent attention to detail, problem-solving abilities, and strong communication skills help these engineers implement rigorous protocols and collaborate with multidisciplinary teams. These competencies are crucial to ensuring compliance with regulatory requirements, maintaining product quality, and protecting critical manufacturing or laboratory environments from contamination risks.

What is a Contamination Control Engineer job?

A Contamination Control Engineer is responsible for identifying, mitigating, and preventing contamination in controlled environments such as cleanrooms, manufacturing facilities, and laboratories. They develop and enforce protocols to control particles, microbes, and other contaminants that could impact product quality and safety. Their role often involves collaborating with cross-functional teams to ensure compliance with industry regulations and standards. Additionally, they conduct risk assessments, implement contamination control strategies, and oversee facility cleanliness to maintain optimal working conditions.

What are the typical challenges faced by Contamination Control Engineers in the workplace?

Contamination Control Engineers often encounter the challenge of identifying and mitigating sources of particulate and microbial contamination in highly regulated environments such as pharmaceutical, semiconductor, or aerospace facilities. They must stay updated with evolving industry standards and continuously optimize processes despite changes in production or facility design. Collaboration with quality assurance, production, and facilities teams is routine, requiring strong communication to implement preventive measures effectively. These challenges can be rewarding, as overcoming them is essential to ensuring product quality, regulatory compliance, and a safe working environment.

Job description

We are seeking a Senior Optical Engineer to join our Optical NPI team to support the development and scaling of next-generation optical switch products from New Product Introduction (NPI) through high-volume manufacturing. This role focuses on the optical subsystem architecture, performance margins, tolerances, contamination sensitivity, and system stability, and will drive validation, characterization, and production readiness from prototypes through product maturity.
This is a highly cross-functional role working closely with NPI, test engineering, manufacturing teams, and customers to ensure robust optical performance and scalable production solutions.
Key Responsibilities
  • Lead deep-dive investigations of complex optical path issues, identifying root causes and driving improvements across design, test, fixtures, and manufacturing processes through structured experiments and DOE methodologies.
  • Partner with NPI and Test Engineering teams to develop manufacturable optical measurement strategies, including selection and integration of optical test equipment for product development and production environments.
  • Collaborate with customers and internal teams to define and implement optical inspection and cleaning processes to improve yield, reduce retest rates, and maintain optical performance standards.
  • Support Site Acceptance Testing (SAT) for automated optical inspection and cleaning systems by defining acceptance criteria, conducting qualification and correlation studies, and closing readiness gaps prior to production release.
  • Qualify optical test equipment and stations through measurement system analysis, including Cg/Cgk, GR&R, and station-to-station correlation studies.
  • Analyze production and test data to identify performance gaps and implement corrective actions prior to mass production.
  • Document technical findings, validation results, and process improvements to support design and manufacturing readiness.

Qualifications
  • Bachelor’s or Master’s degree in Optical Engineering, Electrical Engineering, Physics, or a related technical field.
  • 5+ years of experience in optical engineering, optical testing, or optical manufacturing/NPI supporting complex hardware systems in laboratory or production environments.
  • Proven experience troubleshooting optical path issues, including fiber connectors, end-face quality, contamination control, and optical signal integrity.
  • Hands-on experience implementing optical measurement systems, including automation, calibration, data logging, and traceability.
  • Experience defining and validating optical inspection and cleaning processes in collaboration with cross-functional or customer teams.
  • Strong experimental and analytical skills with experience conducting structured experiments (DOE) and applying data-driven decision making.
  • Ability to produce clear technical documentation and communicate findings to engineering and manufacturing teams.

Preferred Qualifications
  • Experience with optical switching products or high-speed networking optics, including fiber-based interconnects, optical modules, or optical assemblies.
  • Familiarity with high-speed optical link testing and performance metrics such as BER, eye diagrams, jitter margin, and signal integrity analysis.
  • Experience supporting equipment qualification and production readiness, including SAT planning and execution.
  • Working knowledge of measurement system capability analysis including Cg/Cgk, GR&R, and correlation studies.
  • Experience working with mechanical designs and interpreting 2D/3D CAD drawings.

Salary Range:  $140,000 – $180,000 per year
