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
