The role
Builds production machine learning systems: training pipelines, model serving, evaluation harnesses, feature stores. Distinct from applied scientist (research-leaning) and ML platform engineer (infra-leaning) — the senior ML engineer sits in the middle, taking models from prototype to scaled production.
In London, senior ML engineer hiring concentrates around the city's deepest engineering employers - listed financial services, AI-native scale-ups, fintech and the platform/infrastructure tail. Hybrid is the dominant pattern; full-remote is increasingly negotiated for senior IC roles.
