Test Development Engineer - Optical Module

The Client Optics Test Development Engineering for Luxetra focuses on rigorous testing and validation of optical transceivers to ensure high compatibility, reliability, and performance across Cisco and third-party platforms. This includes extensive optics-level, platform-level, and stress testing methodologies designed to simulate diverse environments and identify potential failure points, thereby guaranteeing robust interoperability and seamless operation in multivendor networks. Their work supports the development of optics that meet stringent quality standards and deliver consistent performance in demanding applications such as AI networks and data centers.

We are seeking a talented Test Development Engineer - Optical Module to join the manufacturing engineering team. In this role, you will develop and support automated test solutions for next-generation client optical transceivers and sub-assemblies. You will collaborate closely with hardware, firmware, and manufacturing teams to ensure high-quality product delivery and robust production test coverage.

Key Responsibilities

• Test System Development: implement and validate automated optical test setups for client optics modules using Python or similar languages.

• Instrumentation & Automation:
  Integrate and program electronic/optical test equipment such as Source Meters (Keithley, Keysight), optical power meters, Bit Error Rate Testers (BERTs), and DCA.

• Data Analysis & Reporting:
  Develop data acquisition and analysis scripts/tools to process large datasets, generate yield reports, and drive root-cause investigations.

• Manufacturing Support:
  Deploy and troubleshooting test solutions on manufacturing lines. Provide training and documentation for production teams.

• Cross-Functional Collaboration:
  Work with design, firmware, and reliability engineers to define test requirements, acceptance criteria, and FA (Failure Analysis) procedures.

• Continuous Improvement:
  Identify gaps in test coverage and proactively propose enhancements to test methodologies, automation, and process efficiency.

Minimum Qualifications:

• Education:
  Bachelor’s or master’s degree in electrical engineering, optical engineering, physics, or a related field.

• Experience:
  8+ years of hands-on experience in test development for optical transceivers, photonics modules, or high-speed electronics.

• Technical Skills:

  • Strong Python programming skills (other languages such as C#, LabVIEW are a plus).

  • Proficient with optical and electronic test instrumentation and automation (e.g., VISA, PyVISA, SCPI, GPIB, USB, Ethernet).

  • Familiarity with SQL databases for test data management.

  • Experience with GUI development (Tkinter, PyQt, or similar) is desirable.

• Optical & Electrical Knowledge:
  Understanding of optical communications principles, fiber optics.

• Soft Skills:
  Strong analytical, troubleshooting, and communication skills. Ability to work independently and in a fast-paced, cross-functional environment.

Preferred Qualifications:

• Experience deploying test solutions in high-volume manufacturing environments.

• Knowledge of reliability/lifetime testing (e.g., TEC testing, thermal cycling).

• Experience with data visualization tools and statistical analysis (e.g. JMP).
