## Job description

## About Tacit

We are an early-stage, deep tech startup based in San Francisco, developing innovative hardware that rethinks human-computer interaction. We are backed by General Catalyst, Khosla Ventures, and Greylock Partners, with a founding team from Stanford, BrainGate, Oculus, and Tesla. While we can’t reveal too much just yet, our team is tackling cutting-edge engineering challenges to bring revolutionary products to life.

## About the role

We are looking for an RF Systems Validation Engineer to own scalable RF validation and production test infrastructure from prototype bring-up through manufacturing ramp. The primary focus is RF characterization, system debug, automation, and bench-to-factory correlation. This is a hands-on role for someone who enjoys turning ambiguous hardware behavior into clear measurements, practical debug plans, and decision-ready recommendations. Strong candidates may come from either RF systems validation or manufacturing test backgrounds, with growth into the other areas. We do not expect expertise in every listed area.

## What you'll do

- RF Validation, Characterization, and Debug
- Develop and execute RF validation plans and characterization procedures for radar and connectivity prototypes, engineering builds, and production-intent hardware.
- Characterize RF performance across frequency, power, temperature, configuration, and operating modes.
- Perform systematic RF debug and root-cause analysis for impairments including Conduct coexistence (CoEx), leakage, blockers, desense, nonlinearities, compression, spurs, harmonics, reciprocal mixing, noise coupling, and related RF/system-level behaviors .
- Build RF budgets, compliance matrices, and concise summaries that connect measured behavior to product-level requirements.
- Manufacturing Test & Production Support
- Develop, validate, and optimize RF test flows for manufacturing, including 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, debug guides, and high-level summaries for recurring issues.
- Lab Automation, Instrumentation & Data Analysis
- Automate RF measurements across lab and production test setups using calibrated RF instrumentation and test systems, including VNAs, spectrum analyzers, real-time spectrum analyzers, signal generators, power meters, oscilloscopes, probers, power supplies, phase-noise or noise-figure measurement equipment, switch matrices, call boxes, wireless connectivity testers, and similar tools as needed.
- 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.
- Cross-Functional Product Development
- Work closely with RF design, electrical engineering, firmware, validation, NPI, operations, and manufacturing partners.
- Provide practical feedback on DFM, DFT, test access, calibration hooks, fixture strategy, and debug visibility.
- Communicate complex RF findings in clear, actionable summaries for both technical and non-specialist audiences.

## Requirements

- Bachelor’s or Master’s degree in Electrical Engineering, RF Engineering, Physics, or related technical field.
- 5+ years of experience in RF, electrical, validation, product test, or manufacturing test engineering; senior-level candidates typically bring deeper ownership across product ramps.
- Strong RF fundamentals, including noise floor, thermal noise, integrated noise, sensitivity, link budget, dynamic range, IIP2/IIP3, OIP2/OIP3, P1dB, compression, nonlinearities, blockers, leakage, and desense.
- Hands-on experience with RF lab equipment such as VNAs, spectrum analyzers or RTSAs, signal generators, oscilloscopes, power meters, probers, programmable power supplies, and related calibrated measurement systems.
- Experience with component- and system-level evaluation of RF blocks such as amplifiers, mixers, filters, couplers, splitters, PLLs, VCOs, and noise-sensitive receiver paths.
- Experience developing automated tests or lab scripts, preferably in Python or a similar language, for repeatable RF measurement and data capture.
- Ability to define test matrices, pass/fail limits, compliance matrices, and concise validation reports.
- Experience debugging hardware from prototype bring-up through production-intent builds and manufacturing ramp.
- Comfortable working cross-functionally in a fast-paced hardware development environment.

Strong candidates may have

- Familiarity with wireless connectivity test methods or standards such as Wi-Fi, Bluetooth, BLE, UWB, cellular/call-box workflows, conducted/radiated RF testing, packet-level performance measurements, coexistence, sensitivity, and protocol-level RF validation.
- Experience with high-volume manufacturing test, RF calibration, test fixture bring-up, yield dashboards, or production data pipelines.
- Experience supporting EVT, DVT, PVT, pilot builds, and mass production with contract manufacturers or factory teams.
- Experience evaluating receiver sensitivity, noise figure, spur response, phase noise, harmonic rejection, isolation, and blocker performance.
- Experience with DFM/DFT reviews for RF hardware, including test access, shielding, grounding, layout sensitivities, and fixture repeatability.
- Ability to debug across RF, analog, mixed-signal, firmware, and test software boundaries.

Success in this role looks like

- Product RF performance is thoroughly characterized and well understood.
- Validation plans provide comprehensive coverage of product requirements and technical risks.
- Critical RF issues are identified early and resolved through data-driven root-cause analysis.
- Automated validation infrastructure accelerates learning and improves engineering efficiency.
- Measurement results directly influence product architecture, design decisions, and calibration strategies.
- Validation data correlates strongly with real-world product performance.
- Prototype learnings translate into more robust products and faster development cycles.
