Job summary

Tacit is hiring an EE Systems Validation and Automation Engineer in San Francisco to own scalable electrical hardware validation and production test from prototype bring-up to manufacturing ramp. You will lead board-level characterization, power integrity, SI/PI analysis, and data-driven debugging while building robust lab automation and test flows for manufacturing support.

The role emphasizes cross-functional teamwork with hardware, firmware, and operations to drive reliable, scalable

Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related technical field.
• 5+ years of experience in electrical engineering, hardware validation, product test, or manufacturing test engineering; senior-level candidates typically bring deeper ownership across product ramps.
• Strong electrical engineering fundamentals, including PDN, SI, PI, timing margins, voltage regulation, high-speed digital buses, and analog front-end behavior.
• Hands-on experience with hardware debugging equipment such as high-bandwidth oscilloscopes, logic analyzers, protocol analyzers, digital multimeters, programmable power supplies, electronic loads, and active/differential probes.
• Experience with component- and system-level evaluation of electrical blocks such as buck/boost converters, PMICs, LDOs, microcontrollers, FPGAs, high-speed interfaces (PCIe, USB, Ethernet, MIPI), and low-speed buses (I2C, SPI, UART, CAN).
• Experience developing automated tests or lab scripts, preferably in Python or a similar language (e.g., PyVISA, SCPI).
• Ability to define test matrices, pass/fail limits, compliance matrices, and concise validation reports.
• Experience debugging complex PCBAs and hardware systems from prototype bring-up through production-intent builds and manufacturing ramp.
• Comfortable working cross-functionally in a fast-paced hardware development environment.

Responsibilities

• Develop and execute board-level electrical validation plans and characterization procedures for complex PCBA prototypes, engineering builds, and production-intent hardware.
• Characterize electrical performance across voltage rail tolerances, load transients, power efficiency, temperature, configuration, and operating modes.
• Perform systematic hardware debug and root-cause analysis for impairments including power supply ripple/noise, signal integrity jitter, cross-talk, ground bounce, thermal throttling, unexpected reset events, and analog/digital noise coupling.
• Build power budgets, compliance matrices, and concise summaries that connect measured electrical behavior to product-level requirements.
• Develop, validate, and optimize electrical test flows for manufacturing, including boundary scan, functional test, calibration, limits, guard-bands, and pass/fail criteria.
• Support EVT, DVT, PVT, pilot builds, and manufacturing ramp with data-driven yield analysis and issue resolution.
• Partner with contract manufacturers and operations teams to improve test coverage, cycle time, repeatability, and troubleshooting efficiency.
• Create factory-facing test documentation, board debug guides, and high-level summaries for recurring hardware issues.
• Automate electrical measurements across lab and production test setups using standard board and hardware debugging instrumentation.
• Build test matrices, collect structured datasets, and analyze trends across units, builds, conditions, and configurations.
• Use statistical methods to set limits, identify outliers, separate measurement artifacts from real failures, and drive yield improvement.
• Correlate bench measurements with automated test results and production data to close the loop between engineering and manufacturing.
• Work closely with board layout/hardware design, power electronics, firmware, validation, NPI, operations, and manufacturing partners.
• Provide practical feedback on DFM, DFT, test point access, bed-of-nails fixture strategy, and hardware debug visibility.
• Communicate complex electrical findings in clear, actionable summaries for both technical and non-specialist audiences.
