Job description

Team Credo is looking for a hands-on Optical Test Engineer to support the development and validation of high-speed optical transceiver components and subsystems. The successful candidate will build and test samples for TIA and driver evaluation, develop optical test stations, create test procedures, and analyze measurement results. This role requires strong experimental skills, attention to detail, and the ability to work across optical, electrical, and mechanical disciplines.

Base salary range is $80,000 - $130,000 a year. The base salary offer will depend on factors such as education, experience, training, skills, qualifications, and location. This position is also eligible for a discretionary bonus, equity and a full range of medical and other benefits.

  • Possibilities: Our belief shapes what’s next. Our technology powers the most reliable and energy-efficient connections around the world – and our team powers new products and markets that come next.

Qualifications

Basic Qualifications

  • Master’s degree in Optical Engineering, Electrical Engineering, Applied Physics, or a related field, or a relevant bachelor’s degree plus at least two years of professional experience.
  • Experience testing microelectronic systems and components, such as operational amplifiers, ADCs, DACs, and PLLs.
  • Experience with common optical and electrical test equipment, including optical power meters, oscilloscopes, optical or electrical spectrum analyzers (OSA), variable optical attenuators (VOA), and multi-axis alignment stages.
  • Fundamental understanding of tolerance analysis, yield optimization, reliability testing, and failure analysis.
  • Programming experience in one or more of Python, C/C++, MATLAB, or LabVIEW.

Preferred Qualifications

  • Hands-on experience in optical alignment and fiber coupling for lasers, photodiodes, PICs, or similar optical components.
  • Experience with high-speed optical and electrical testing, instrumentation control, data acquisition, and test automation, including developing automated test systems for high-volume characterization and validation.
  • Experience with optical design and simulation tools such as OpticStudio (Zemax) and mechanical CAD software such as SolidWorks.
  • Knowledge of photonic packaging, optical assembly processes, and manufacturing methods.
  • Familiarity with statistical data analysis and Design of Experiments (DOE).

Responsibilities

  • Perform precision optical alignment and fiber coupling of lasers, photodiodes (PDs), photonic integrated circuits (PICs), and waveguide-based devices.
  • Build and characterize optical assemblies for TIA and driver validation, including optical-to-electrical (OE) and electrical-to-optical (EO) conversion testing; design, assemble, and maintain optical test stations and experimental setups for device characterization.
  • Develop test procedures, automate measurements, collect data, and generate technical reports.
  • Conduct high-speed optical and electrical measurements to evaluate device performance, reliability, and yield; analyze results, troubleshoot issues, perform root cause investigations, and recommend design and process improvements.
  • Collaborate with optical, electrical, mechanical, and manufacturing engineers to support product development and qualification activities, following laser safety procedures and laboratory best practices.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
