Embrox Solutions is a hardware & software product engineering company with offices in Lviv, Ukraine and Tallinn, Estonia. We design and build connected products — from smart home devices and fitness equipment to healthcare and energy solutions — that end up in real hospitals, gyms, homes, and studios worldwide. Our teams cover the full product cycle: embedded firmware, hardware design, mobile/web apps, and cloud connectivity. We’re looking for a proactive Manual QA Engineer (Junior+/Middle level) to join our QA team and own the testing of our IoT products end-to-end — the physical device, its firmware, the companion app, and the cloud layer that connects them. (Please note: we consider candidates from Lviv only, office-based role.)

Necessary skills and qualifications:

• 2–3 years of experience in manual QA (software and/or hardware)
• Solid understanding of QA fundamentals: test case design, test plans, bug lifecycle, reporting
• Experience testing physical devices/hardware integrations, or strong motivation to grow into hardware testing
• Conceptual understanding of embedded systems and connectivity protocols (BLE, Wi-Fi, Zigbee, MQTT)
• Experience with bug tracking and test management tools (Jira, TestRail or similar)
• High attention to detail and comfort working with test benches and lab equipment
• Intermediate+ English (team and client communication)
• Readiness to work full-time from the Lviv office

Would be a plus:

• Experience testing IoT / connected devices, wearables, or smart home products
• Familiarity with basic electronics and lab tools (multimeter, power supply, oscilloscope)
• Experience with API testing (Postman)
• Basic scripting for test automation (Python)
• Understanding of hardware communication protocols: I2C, UART, SPI, BLE, Zigbee

Responsibilities:

• Design, document, and execute manual test cases covering hardware, firmware, companion app, and cloud connectivity
• Test physical prototypes and production devices together with embedded firmware and connected software
• Set up and run test scenarios on lab test benches
• Log, track, and verify bug fixes in Jira; write clear, reproducible bug reports
• Collaborate closely with embedded, hardware, and software engineers throughout the release cycle
• Maintain and improve test documentation, checklists, and QA processes
• Participate in requirements and design reviews to catch issues early in the product cycle
