What are the responsibilities and job description for the Analog/Mixed-Signal Test and Characterization Engineer position at Nokia?
Job Description
The Optical Module Group is looking for a motivated test and characterization engineer to support development of our control ASIC. This role offers the opportunity to join a world-class team at the forefront of high-speed analog and mixed-signal design, where you'll gain hands-on experience in characterizing high-precision data converters (DACs and ADCs) and deepen your understanding of real-world circuit behavior. You’ll independently lead lab characterization and design validation efforts, collaborate with design and systems teams to define experiments and test plans, and develop automated scripts for efficient data acquisition. You'll also build and maintain test infrastructure, perform statistical analysis to extract performance trends, correlate lab and ATE measurements with simulation data, assist with analog/mixed-signal simulations, and contribute to layout tasks—accelerating your growth in ASIC development and validation.
