ph3About the job /h3 pWe are developing a highly scalable media intelligence platform that processes, analyzes, and structures large volumes of multimedia content across text, image, video, and audio. As a Senior Applied ML Engineer, you will architect and build the core backend systems that power media ingestion, processing workflows, metadata generation, AI-based analysis, semantic search, and retrieval across large media libraries. /p pWe are looking for a Senior Applied ML Engineer who can design, implement, optimize, and evaluate a production‑grade moderation pipeline using open‑source models. /p pThis role requires deep backend engineering expertise, strong system design capability, and practical experience integrating AI/ML systems into production workflows. You will work on complex media‑processing pipelines, video/audio analysis, OCR, speech‑to‑text, embedding generation, vector search, multimodal model integrations, and high‑throughput asynchronous workloads. You will collaborate closely with engineering leadership to define backend architecture, improve reliability and scalability, and guide other engineers in delivering secure, observable, and high‑performance systems. /p h3Responsibilities /h3 h3Backend Architecture System Ownership /h3 ul liArchitect, build, and operate scalable backend services for a media intelligence platform, with a
