Codewerk Tech Stack

Embedded and industrial software for rail and manufacturing

Software Development Karlsruhe 51–200 employees Founded 2014 Privately Held

Codewerk builds embedded systems, IoT applications, and cloud architectures for rail operators and industrial manufacturers, with deep integration into legacy control systems (SIMATIC PCS 7, PROFINET, OPC UA). The tech stack is heavily weighted toward industrial protocols and real-time embedded work (C, C#, AUTOSAR, MATLAB) rather than modern cloud tooling, reflecting a customer base operating mission-critical infrastructure. Active hiring skews toward engineering (27 roles) with a notable intern cohort (12), suggesting junior-heavy ramp for domain-specific technical onboarding.
