Summary
👤
Senior🎓
Top SchoolChristian Stier is a Principal Software Development Engineer based in Karlsruhe with 11 years of experience designing and shipping complex engineering and cloud solutions. He blends research-grade rigor (Dr.-Ing. in Informatics, summa cum laude) with hands-on product delivery, leading architecture and implementation for automotive tooling and observability features at VECTOR Informatik. His work includes building an APM stack on OpenTelemetry, Jaeger, Elasticsearch and Kibana and driving a domain-specific language for PREEvision, showing strength in both systems integration and developer-facing platforms. Earlier research roles at FZI had him leading architecture integration for European cloud projects, simulation platforms, and CI for IaaS optimization—skills he now applies to production-grade software. Colleagues describe him as an architect who moves easily between prototype research and scalable product engineering, often surfacing practical optimizations that are not obvious from requirements alone.
