Lead Software Engineer at Vodafone
Berlin, Germany
Summary
👤
Senior🎓
Top SchoolSebastian Kaiser is a Lead Software Engineer based in Berlin with 12 years of experience designing and operating distributed, event-driven backend platforms that prioritize correctness, traceability, and operational reliability. He builds high-throughput ingestion, decoding, normalization, and fan-out systems across time-series and relational stores, and routinely makes architectural decisions that hold under scale and failure. At Vodafone he has driven migrations, release processes, and mentoring across multinational teams supporting hundreds of thousands of IoT customers, and he blends hands-on Java/Go/Rust development with systems thinking. Beyond production engineering, he is exploring correctness-by-construction and reproducible, audit-grade decision models that enforce closed input boundaries and refusal semantics. Colleagues rely on him for predictable, observable systems and for shaping data flow and invariants rather than just implementing features.
