RF & EE Validation Engineer (Autonomous Products)

Quick Facts

• Role: RF & EE Validation Engineer (Autonomous Products)

• Focus: Hardware validation for a Telematics Control Unit (TCU) connecting vehicles/energy products/robots to cellular, Wi‑Fi/Bluetooth, and GNSS

Description

Own end-to-end hardware validation for the TCU, including test architecture, DV/PV planning, and pass/fail criteria across cellular, Wi‑Fi/Bluetooth, and GNSS. Execute RF transmitter/receiver parametric validation, OTA TRP/TIS and MIMO performance checks, GNSS/NTN capability validation, and electrical platform verification under automotive power/thermal constraints. Build and automate a Python-based test framework and lead root-cause debug to determine hardware readiness for certification and production.

Responsibilities

• Define the TCU validation strategy: test architecture, DV/PV plan, pass/fail criteria, and program gate entry/exit criteria

• Perform cellular parametric tests (e.g., EVM, ACLR, spectral flatness, spurious emissions, sensitivity, blocking) across bands, power, and temperature corners

• Own OTA parametric validation (TRP/TIS) and multi-antenna MIMO performance (ECC, diversity imbalance), correlating conducted and OTA results

• Lead GNSS performance and NTN satellite-to-cellular validation (TTFF, acquisition/tracking sensitivity, C/N0, interference resilience)

• Identify and debug platform desensitization (e.g., MSD from harmonic/intermodulation during carrier aggregation and multi-radio operation) and validate mitigations

• Validate electrical platform behavior: high-speed digital interfaces, PDN, and memory architecture against automotive thermal/space/key-off current constraints

• Architect and implement Python test automation (SCPI/VISA + vendor APIs, hardware abstraction, reusable library, sequencer, structured reporting)

• Automate bench setup and DUT provisioning, including RF routing/switch matrices, attenuators, thermal/OTA positioning, power supplies, firmware flashing, SIM/modem configuration, AT commands, and CAN control

• Drive readiness for certification and regulatory compliance via in-house pre-screening (PTCRB, GCF, FCC, ISED, CE/RED)

• Partner with hardware/firmware/manufacturing and chipset vendors; bridge validation into factory calibration/test flow and mentor engineers/technicians

Requirements

• Degree in Electrical Engineering, RF/Microwave Engineering, Telecommunications, or a related field (or equivalent experience)

• 5+ years hands-on RF/EE validation experience for P3 or 8+ years for P4, with technical ownership of multiple programs

• At least one product taken through certification and volume production

• Automotive, telematics/TCU, mobile handset, IoT, or telecom hardware experience (TCU strongly preferred)

• Strong command of 3GPP physical-layer requirements and RFFE architectures plus signal/power integrity fundamentals

• Demonstrated cross-domain debugging across the RF/EE boundary

• Hands-on cellular callbox and network emulator experience (e.g., Keysight UXM, R&S CMW500/CMX500, Anritsu MT8000A)

• Expert instrument skills: VNAs (calibration/embedding/de-embedding), spectrum/signal analyzers, oscilloscopes (including high-bandwidth and jitter/eye for digital and memory), and power meters

• GNSS simulator experience (e.g., Spirent GSS-series, Safran/Orolia) including multi-constellation and TTFF scenarios

• Python (preferred), or MATLAB/LabVIEW, for instrument automation, unattended sweeps, and parametric data analysis with calibration traceability and uncertainty budgets

• Ability to communicate clearly and own multiple programs on aggressive schedules

Benefits

• Competitive pay and full-time employee benefits from day 1, including medical/dental/vision, HSA contribution, FSA, 401(k) match, life/disability insurance, paid time off/holidays, and employee assistance programs

• Additional voluntary benefits (e.g., critical illness, hospital indemnity, accident insurance, legal services, pet insurance), childcare/support resources, commuter benefits, discounts, and employee perks

• Earned Wage Access (real-time pay access paid daily) subject to eligibility

Expected Compensation

$109,600 - $234,000 annual salary + cash/stock awards and benefits
