Appliances, Electrical, and Electronics Manufacturing Vantaa 1,001–5,000 employees Founded 1936 Public Company

Vaisala manufactures precision measurement devices and data platforms for climate action, with a 90-year operational history and ~2,500 employees across Finland, North America, Europe, and Asia. The tech stack reveals a hardware-software hybrid: embedded systems (C, C++, FreeRTOS, Zephyr) paired with modern ML tooling (TensorFlow, PyTorch, scikit-learn, XGBoost) and enterprise systems (SAP, Salesforce). The intern-heavy hiring profile (57% of open roles) alongside calibration automation and lab technician training projects suggests scaling manufacturing competency and quality control as core near-term priorities.
