Software Development San Francisco, California 51–200 employees Founded 2019 Privately Held

Proximity Works operates a production AI infrastructure business serving major sports, media, and entertainment platforms across 200+ countries. The stack reveals dual-track engineering: Python/R/Spark for ML and data pipelines; Node.js/React for mobile and content delivery; AWS/GCP/Azure for polycloud ops. The hiring mix is heavily senior-weighted (23 of 29 roles) and engineering-dominant (15 engineering + 6 data roles), indicating mature technical problems — confirmed by active projects targeting runtime systems, RAG pipelines, feature stores, and real-time streaming at scale. The pain-point list (performance reliability, cost optimization, SLA targets, scaling mobile stacks) tracks how they operate under the constraints of massive-audience platforms.
