Senior PCBA Test Engineer
Mountain View, CAFull-TimeSeniorQA / Testing
What you'll be doing:
- Drive PCBA testability (DFT) from schematic review through high-volume manufacturing. Integrate test points, boundary scan, and other DFT techniques into PCB designs to enhance test coverage and fault detection. Define and enforce test access requirements: test points, boundary scan chains, probe access, isolation, and segmentation.
- Develop test methods using python programming used for functional and parametric test on NPI PCBA test stations developed in-house at Aeva.
- Define the test requirements and support the development of functional test (FCT) at CM for high volume manufacturing.
- Bring up new PCBA tests from first power-on to full functional validation.
- Isolate intermittent, marginal, and low-yield failures using systematic debug methods including debug of power integrity, clocks, resets, boot sequences, and mixed-signal paths.
- Correlate ICT/FCT failures with schematic intent, layout, and silicon performance.
- Use advanced instrumentation (scopes, logic analyzers, current probes, thermal tools) to capture elusive failures.
- Create debug playbooks, DFT guidelines, and failure isolation documentation.
- Collaborate with engineering and manufacturing teams to ensure on time delivery with optimum test coverage at lowest cost.
- Document test strategies, procedures, and results for internal reference and compliance purposes.
- Prepare reports to analyse and document test results, and perform SPC analysis of new test fixtures/techniques to validate or establish monitors of critical test processes.
- Provide end-to-end support through entire product life cycle from NPI (New Product Introduction) to high volume manufacturing.
What you'll have:
- Bachelor’s degree in Electrical/Electronics Engineering or equivalent experience
- 7+ years of hands-on PCBA test, debug, and DFT experience
- Expert ability to read and critique schematics and PCB layouts
- Deep understanding of analog, digital, power, and mixed-signal systems
- Strong practical knowledge of ICT, FCT, and boundary scan (JTAG)
- Proven track record of improving yield through DFT and failure analysis learnings
- Strong understanding of electronics, digital and analog circuits, and PCB assembly processes.
- Proficiency in PCB design software tools such as KiCAD, Cadence, or similar.
- Hands-on experience in Python programming for test automation.
- Experience with data analysis using tools such as JMP and dashboards.
- Excellent problem-solving skills and the ability to troubleshoot complex technical issues.
- Strong communication and teamwork skills to collaborate effectively with cross-functional teams.
- Experience working with CMs worldwide.
- Excellent verbal and written communication and presentation skills and capable of making clear conclusions and recommendations.
