Senior🎓
Top SchoolAdam Liddell is a Senior Media Backend Engineer based in London with 10 years of cross-stack experience building high-performance, resilient systems for real-time and mission-critical environments. He blends low-level C++ DSP and hardware troubleshooting with Python and Go back-end services, reproducible Bazel builds, Kubernetes deployments and reactive Vue front-ends. At Inmarsat/Viasat he led development and operational rollout of a TensorFlow-based phased-array beamforming system and a millisecond-scale adaptive signal filtering pipeline, and he remains focused on reliability with Patroni-backed Postgres failover and strong CI practices. He contributes to build-system tooling by refactoring Bazel rules for protobuf/gRPC across multiple languages, reflecting a practical attention to developer ergonomics and multi-language ecosystems. Colleagues rely on him for rapid on-site problem solving that spans software, hardware and RF systems—skills proven during multiple in-orbit test campaigns.
