Hardware Test Engineer

The role You will own validation of our hardware from first prototype to serial production. Every board we ship goes to the front line, where a failure costs more than a warranty claim - your job is to find it first. • Location: Kyiv, on-site • Employment: full-time • Reports to: R&D lead Responsibilities • Write test plans and procedures for new PCBs and devices: bring-up, functional, RF, power and environmental tests • Bring up first prototypes and debug failures down to component level together with the design engineers • Measure RF performance of LoRa/BLE links: output power, sensitivity, antenna matching (VNA), range tests in field conditions • Characterize power consumption in sleep and active modes and verify battery life against the 6–12 month target • Run environmental tests: temperature (−20…+50 °C), humidity, ingress, vibration and drop • Validate seismic sensor channels: sensitivity, noise floor, false-alarm rate on reference signals • Build and maintain test jigs and fixtures (pogo-pin beds, programming stations) and automate tests in Python • Define end-of-line production tests and pass/fail criteria; train assembly staff to run them • Keep test reports, failure logs and root-cause analyses that feed back into the next hardware revision • Join field trials with units to confirm lab results under real conditions Requirements • 2+ years in hardware testing, validation or electronics R&D • Degree in electronics, radio engineering, physics or equivalent hands-on experience • Confident with lab equipment: oscilloscope, multimeter, lab PSU, electronic load, spectrum analyzer or SDR, VNA • Read schematics and layouts; comfortable with SMD soldering and rework • Understand embedded systems: microcontrollers (STM32 or similar), UART/SPI/I2C, flashing and debugging firmware • Python for test automation and data processing • Methodical: you document what you test, how, and what came out - so anyone can repeat it • Ukrainian fluent; technical English for datasheets and standards Nice to have • RF test experience: LoRa, sub-GHz radio, link budget and antenna measurements • Low-power design and current profiling (nA–mA range, e.g. Power Profiler, Joulescope) • Experience with sensors and signal processing: accelerometers, piezo, seismic or acoustic • Knowledge of MIL-STD-810 / IEC 60068 environmental testing or IP-rating tests • Production test experience: ICT, end-of-line fixtures, yield tracking • Drone electronics: Betaflight/ArduPilot, ELRS, ESCs • Background in defense, security or industrial electronics What we offer • Work that ships to the front within weeks, not years - you see the effect of your tests directly • Ownership of the test function: you set up the lab process and production test from the ground up • Competitive salary, reviewed after probation • Reservation from mobilization (бронювання) for employees • Modern lab: VNA, spectrum analyzer, climate chamber, in-house CNC and prototyping • Small team, short decision loop - direct access to the founder and R&D lead • Budget for equipment, courses and conferences
