At Bloq.it, we’ve created the world’s leading smart locker solution. Solving online deliveries by enabling everyone to participate easily, reducing delivery costs and making them more sustainable.
We’re quickly expanding, and after growing at 1000% for three years in a row, we’re now the fastest-growing Smart Locker company in the world and one of the fastest growing scale-ups in Europe.
We are in search of a Senior Test Engineer – IoT & Embedded Systems to join our innovative team as our new #bloqstar. In this role, you'll play a crucial role in building the first dedicated IoT/embedded test practice at Bloq.it, designing automated frameworks and “break-the-locker” stress regimes that guarantee rock-solid quality across hardware, firmware, and cloud connectivity.
What will be your responsibilities
- Own the IoT/embedded test strategy—define standards, tooling, and metrics for functional, regression, performance, and stress testing of smart-locker devices.
- Design and implement automated test frameworks (HIL, SIL, network simulators) that integrate with our CI/CD pipeline for every firmware and hardware release.
- Develop rigorous stress and fault-injection campaigns, validating connectivity, power resilience, environmental robustness, and OTA update reliability.
- Collaborate with Hardware, Firmware, Cloud, and Field-Service teams to reproduce field issues, identify root causes, and drive corrective actions.
- Create and maintain test fixtures and labs, including custom jig design, sensor rigs, and remote-access infrastructure for distributed testing.
- Analyze test data and fleet telemetry, building dashboards that highlight quality trends, regression hotspots, and reliability KPIs.
- Mentor QA and engineering peers, evangelizing best practices and fostering a quality-first culture across the company.
What are the requirements to join us in this position
- 7 + years of hands-on testing experience with embedded or IoT products (MCUs, SoCs, gateways) in high-availability environments.
- Proficiency in Python (PyTest, Robot, or similar) and at least one systems language (C/C++, Rust, or Go) for low-level test harnesses.
- Demonstrated success building HIL/SIL frameworks, automated stress rigs, or environmental chambers and integrating them into CI (GitLab/GitHub Actions, Jenkins, etc.).
- Deep understanding of embedded Linux/RTOS internals, bootloaders, OTA mechanisms, and common IoT protocols (MQTT, HTTP, BLE, CAN, Modbus, etc.).
- Experience with lab instrumentation and measurement tools (oscilloscopes, logic analyzers, power analyzers, network emulators).
- Strong analytical skills—able to turn raw logs, metrics, and telemetry into actionable insights that raise product reliability.
- Fluency in English, both verbal and written.
Extra valued skills
- Familiarity with cloud IoT platforms (AWS IoT Core, Azure IoT, GCP) and edge-to-cloud observability stacks.
- ISTQB Advanced, Certified LabVIEW Developer, or similar testing/quality certifications.
