Test Embedded Engineer/ RF Engineer

We are seeking an Embedded Test Engineer with expertise in RF and hardware testing.

In this role, you will be responsible for the development, implementation, and optimization of production test solutions for highly integrated SoC (System on Chip) devices. Your expertise will span across Digital, Mixed-Signal, and RF domains.

By joining us, you become a member of the Embedded Competence Center at Sii - an internal organizational unit, bringing together more than 500 specialists nationwide! We are currently working on projects for 50 clients from various industries, including automotive, IoT, telecommunications, and medical.

Your tasks

• Design and oversee the fabrication of complex Load Boards (DIBs) and Probe Cards. This includes PCB schematic capture and layout review to ensure signal integrity for high-speed digital and RF paths
• Create, debug, and maintain automated test equipment programs (e.g., Advantest V93K, Teradyne UltraFLEX) for wafer sort and final test
• Develop characterization and production test plans for ADCs, DACs, PLLs, and RF components (LNA, PA, Mixers)
• Collaborate with Design and Validation teams to correlate ATE results with bench measurements and design simulations
• Analyze large datasets using statistical tools (JMP, Spotfire) to identify yield detractors, perform root-cause analysis, and implement test time reduction (TTR) strategies
• Provide feedback to the design team on DFT features such as Scan, BIST (Built-In Self-Test), and Loopback modes to improve test coverage and observability
  
  

Requirements

• At least 5 years of experience in IC testing, with a focus on Mixed-Signal and RF products
• Proficiency in C/C++, Python, or Perl for test automation and data analysis
• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related discipline
• Hands-on experience with industry-standard ATE platforms (e.g., Advantest, Teradyne, or Cohu)
• Strong understanding of RF parameters such as S-parameters, NF (Noise Figure), IIP3, EVM, and Phase Noise
• Experience with lab equipment, including Oscilloscopes, Spectrum Analyzers, and Vector Network Analyzers (VNAs)
• Strong problem-solving skills and the ability to work effectively in a team environment
• Residing in Poland required
  
  

Nice to have

• Knowledge of automotive test standards (AEC-Q100) or aerospace reliability requirements
