- Willingness and ability to specify, build, and qualify new test equipment and develop of in-house laboratory capabilities.
- Deep understanding of environmental testing (e.g., thermal, humidity, vibration, drop, and ingress protection) and relevant standards (IEC, MIL-STD).
- Proficiency in reliability methodologies such as FMEA (Failure Mode and Effects Analysis), HALT/HASS, and statistical analysis (e.g., Weibull, MTBF).
- Excellent collaboration skills and the ability to support cross-functional stakeholders (Design, Project management, Sourcing, Manufacturing).
- A strong network of external testing and validation partners
- Fluency in English
This is a hands-on role in our Helsinki-based team. Because you’ll be working with physical devices and prototypes, the work will be performed mostly on site at our headquarters in Kaisaniemi. Full remote work is not possible in this role.
