LACROIX is a €445M public manufacturing group designing embedded electronics and IoT solutions for automotive, aerospace, and critical infrastructure (water, energy, HVAC). The tech stack—Java/Spring Boot, Kafka, PostgreSQL, SAP, plus AWS/Azure—reflects a hybrid on-premise/cloud architecture typical of industrial operators. Current hiring momentum (14 roles in 30 days, accelerating velocity) centers on engineering and manufacturing, with notable activity in security (VP-level Information Security role, SOC/XDR deployment, ISO 27001 push). The concurrent adoption of XDR and Bastion, paired with projects around data classification via Microsoft Purview, signals an active security-posture upgrade to meet aerospace/defense compliance.
