Sioux Technologies is a 1,200-person engineering-heavy organization building embedded software, electronics, and mechanical systems for industrial customers. The tech stack—C/C++, ARM Cortex-M, FreeRTOS, Zephyr, AWS—reflects a core focus on low-level embedded and real-time control, paired with modern CI/CD (Jenkins, TeamCity, GitLab) and cloud infrastructure. Active projects span medical devices, electron microscopes, lithography machines, and NPI (new product introduction) workflows, all pointing to mission-critical, regulated hardware; concurrently, the team is addressing legacy code migration and automating security testing (IEC 62443 compliance), signaling maturation of both codebase and governance as they scale.
Sioux Technologies is a privately held engineering firm based in Eindhoven, Netherlands, serving customers in industrial automation, life sciences, and semiconductor equipment manufacturing. The company designs and assembles complex hardware-software systems, with particular depth in embedded firmware, electronics design, and integrated mechatronics. A distributed workforce spans the Netherlands, Belgium, Germany, and Vietnam. The hiring profile—37 engineering roles against 5 in manufacturing—indicates that software and systems engineering, rather than assembly, is the growth engine. Current operational challenges center on NPI process optimization, legacy architecture modernization, and supply-chain resilience.
Primarily C/C++, C#, ARM Cortex-M, FreeRTOS, Zephyr, and Linux for embedded systems; AWS for cloud infrastructure; GitLab, GitHub, Jenkins, and TeamCity for CI/CD; and tools like Docker, CMake, and Yocto for build and deployment automation.
Projects include compact electron microscopes, advanced lithography machines, medical device automation systems, cloud infrastructure for data analysis, IEC 62443 security certifications, and ongoing new product introduction (NPI) workflows with quality management system integration.
