Full Job Description
Job Purpose

The Test Development Engineer role will be a key contributor in defining, developing, and deploying high quality, automated Functional Test (FT) and System Test solutions for complex electronic devices, with a specialization in RF, Optical, and Pluggable equipment. This role focuses on both software and hardware test development. While you will write robust, scalable test code in Python, C or C++ for RF and optical testing, you will also design test fixtures, requiring foundational knowledge in electronic and mechanical engineering to ensure product quality, performance, and compliance.

Nature of Duties/Responsibilities
  • Define, develop, and execute functional and system-level test solutions for customers' products, encompassing the design of test hardware (fixtures/cables) and test software, with a strong emphasis on Python for automation.
  • Work with R&D and Manufacturing teams to implement test strategies for new product introduction (NPI) and volume manufacturing of RF, Optical, and Pluggable devices.
  • Develop automated test scripts and frameworks to control test equipment, collect data, and generate comprehensive test reports.
  • Expertly perform and implement testing for high-speed digital and high-frequency RF/Optical measurements.
  • Troubleshoot, debug, and resolve hardware, software, and measurement issues across test fixtures, automation code, and units under test (UUT).
  • Manage the process for manufacturing test by developing and documenting criteria, justifying exceptions, and ensuring proper implementation in the test flow.
  • Create, verify, and maintain essential test documentation (test plans, test procedures, test setups, debug instructions, training manuals, etc.).
  • Perform Design for Testability (DFT) analysis of customer designs, focusing on access points and test points relevant to functional and system-level testing.
  • Interface and travel to other sites to successfully transfer and sustain test solutions globally.
  • Provide leadership and training to manufacturing test personnel on new test procedures, code automation, test equipment, and troubleshooting techniques.


Education and Experience
  • Relevant Degree in Electrical Engineering, Computer Engineering or equivalent work experience.
  • Minimum of 5 years of relevant functional test development experience.
  • Mandatory hands-on experience in the development, verification, documentation, and deployment of complex automated Functional Test (FT) solutions - from prototyping/NPI to volume manufacturing.
  • Expert-level proficiency in Python, C, or C++ programming for test automation, including experience with relevant libraries (e.g. PyVISA or similar instrumental control libraries).
  • Proven experience testing electronic devices, specifically:
    • RF (Radio Frequency) devices and associated measurements (e.g. power, spectrum, 5-parameters).
    • Optical devices and measurements (e.g. power, wavelength, insertion loss).
    • Pluggable devices (e.g.SFP/QSFP transceivers, cable assemblies).
  • Demonstrated experience with VNA testing methodologies and equipment.
  • Experience in defining, documenting, and implementing test processes and procedures.
  • Hands-on experience with debugging tools and essential test equipment such as oscilloscopes, spectrum analyzers, network analyzers, and optical test equipment.
  • Working knowledge of test software like National Instruments Labview and TestStand is a definite asset.
  • Experience in failure analysis, diagnostics, and debug to resolve complex functional test problems.
  • Proven analytical problem solving skills and decision making capabilities.
  • Excellent organizational, interpersonal, communication, reporting and presentation skills.

OTHER INFORMATION
  • The compensation range for this position is $90,000- $110,000 annually.
  • This position is for an existing vacancy.
  • The hiring process for this position does not use Artificial Intelligence (AI).
