Join us now on our global journey, where we strive to push limits and build ground-breaking technology for consumer markets across the globe!


  • Develop and execute tests on the lab bench per the validation plan during pre-silicon and post-silicon phases of the product to ensure functionality and performance as per the datasheet
  • Think beyond the datasheet and around design corners to find elusive bugs.
  • Able to think of test cases and customer usage models that may violate the assumptions of designers and systems engineers.
  • Develop automated test framework, regression test suites in Python and/or LabVIEW to optimise validation efficiency.
  • Work with validation peers to implement standard methodologies and continuous improvements to Cirrus Logic validation methodologies
  • Collaborate closely with IC Design engineers, System Engineers, and Application Engineers to understand requirements and use cases
  • Debug analog/digital silicon issues, board issues and Validation software/hardware tools issues.
  • Analyse test results and identify failures/defects using business intelligence tools such as Spotfire.
  • Synthesise RTL designs targeted to custom Xilinx FPGA platforms, test and debug the FPGA model and perform full-chip emulation on FPGA platform
  • Design silicon validation board schematics and bring-up the platforms.
  • Develop and work with supporting HW (FPGA, DSP, ARM, 8051, JTAG, debuggers) and SW (C, Assembly, scripts) collateral.

Required Skills and Qualifications

  • Bachelor’s degree in Electronics, Computer Science or other related subject areas, and/or relevant proven experience in a related field
  • Sound electrical engineering knowledge in analog, digital, power electronics or audio engineering. This includes mixed signal building blocks such as ADC, DAC, PLLs, amplifiers, signal processing and measurement, IC control/communication protocols
  • Solid hands-on experience in lab equipment such as oscilloscopes, signal generators, audio analyzers, logic analysers, spectrum analysers for measurement and debugging issues
  • Self-motivated with excellent problem-solving skills and attention to detail - you will need to understand silicon, board and software interactions
  • A highly driven approach to problem solving
  • Good communicator and team player

Preferred Skills and Qualifications

  • Proven background in niche areas such as post silicon validation, mixed-signal IP block design/validation, audio related signal processing, power management and algorithm, validation related automation framework
  • Experience in various automation framework hardware tools (FPGA, DSP, NI Data Acquisition) or software tools/languages (Scripting languages such as Python, SQL, test sequencers such as NI Teststand, Spotfire, schematic capture tools).
  • Experience in automation and scripting/programming languages such as MATLAB, LabVIEW, C, Python or similar
  • Shown proficiency in system understanding of various industry interface standards such as I2C, SPI, USB, I2S, TDM or high-speed control/data bus as examples
  • Experience in version control tools such as Preforce and Git

This position is based in Edinburgh
