Principal R&D Engineer (Optical)

Nordson Test & Inspection , a global leader in X-Ray & Test Systems and Optical Sensors and Metrology, is seeking an experienced and highly motivated individual to join our team. We are committed to creating a diverse and inclusive workplace, and we are looking for candidates who share that same commitment.

Summary of the role

As a member of our team, you will have the opportunity to work in a dynamic and collaborative environment, where your ideas and contributions will be valued and respected.

Position Summary

The Principal Mechatronics Test & Development Engineer is responsible for establishing and executing the verification, validation, and calibration strategy for one optical metrology product line, while contributing hands‑on to prototype builds, integration, and design maturation.

Essential Duties & Responsibilities

Test & Calibration Ownership

Define the verification plan and acceptance criteria for builds and pilot runs; maintain requirements‑to‑test traceability.

Design and implement calibration methods for optical and electro‑mechanical subsystems, including reference artifacts and uncertainty analyses.

Build, maintain, and document automated test scripts and data pipelines; ensure configuration control and code quality standards.

Plan and execute environmental, stability, and reliability evaluations; synthesize findings into design recommendations.

Create and maintain controlled procedures, work instructions, and training for test and calibration activities.

Mechatronics Development Support

Design and release test fixtures and jigs (SolidWorks/Creo), including tolerance stack‑ups and GD&T suitable for fabrication.

Support prototype bring‑up and integration (motion control, sensors, electrical harnessing, mechanical alignment, optical alignment as applicable).

Conduct structured experiments to isolate contributors to measurement error and drive corrective actions.

Cross‑Functional Collaboration

Serve as technical owner for test/calibration for the assigned product line; act as the counterpart to the Systems Engineer.

Partner with Opto‑Mechanical, Electrical, Software, and Algorithm teams to resolve integration issues and close validation gaps.

Align R&D test methods with factory test requirements; support DFM/DFT/DFC and pilot builds.

Provide concise status reporting (risk register, decision logs) to stakeholders and leadership.

Minimum Qualifications

• Bachelor’s degree in Mechanical, Electrical, Mechatronics, Optical Engineering, or related discipline; Master’s preferred.
• 7+ years of experience developing mechatronic systems from prototype through pilot/transfer; experience in optical systems/metrology strongly preferred.
• Demonstrated proficiency in test automation and data analysis using Python and/or Matlab, LabView ; familiarity with C# for instrument control is a plus.
• Proficiency in CAD ( SolidWorks or Creo ) with the ability to release build-ready drawings (GD&T, tolerance stacks).
• Practical experience with motion stages, precision mechanics, sensors, DAQ, and lab instrumentation.
• Working knowledge of calibration design, error budgets, statistics, and Measurement Systems Analysis (MSA/GR&R).

Preferred Qualifications

• Optics/optomechanics (imaging, interferometry, alignment, light fundamentals).
• Exposure to manufacturing transfer and factory test development.
• Experience with reliability or environmental testing (thermal, vibration, shock), and regulatory compliance is a plus.
• Key Competencies
• Systems Thinking: Converts requirements and risks into measurable test criteria and coverage.
• Technical Rigor: Balances rapid prototyping with disciplined productization.
• Communication: Produces clear documentation and executive‑level summaries.
• Leadership & Mentorship: Coaches junior engineers
