About this role

OpusClip is hiring a full-time Lead AI Researcher to work on cutting-edge video intelligence technology in Mountain View. This hands-on position suits an experienced machine learning professional who wants to build scalable generative and multimodal models for content creators.

Role Overview

The Lead AI Researcher will guide the technical direction of artificial intelligence initiatives at OpusClip in Mountain View. This role focuses heavily on hands-on engineering, taking advanced models from initial prototypes all the way to large-scale production. The ideal professional balances technical depth with pragmatic product thinking, ensuring that model quality, speed, and infrastructure costs align effectively.

Key Responsibilities

Build and deploy scalable AI and machine learning models from prototype stages directly to production environments.
Design and execute post-training workflows, encompassing fine-tuning, preference optimization, robust evaluation, and active learning from user feedback.
Establish powerful data flywheels that transform user interactions into continuous model training improvements.
Optimize inference performance for self-hosted models to maximize throughput, minimize latency, optimize GPU utilization, utilize quantization, and control serving expenses.
Implement comprehensive evaluation strategies utilizing offline benchmarks, human assessments, online experiments, and product quality metrics.
Apply large language models and multimodal networks to video functions like highlight detection, content curation, personalization, ranking, and automated editing.
Make strategic build-versus-buy evaluations across proprietary APIs, internally trained systems, and open-source models.
Formulate technical roadmaps, perform architectural reviews, guide engineering peers, and lead a compact, high-achieving artificial intelligence group.

Requirements

Demonstrated track record of shipping AI and machine learning models to production at scale.
Comprehensive expertise in model post-training techniques, preference optimization, fine-tuning, evaluation metrics, and learning loops derived from user feedback.
Extensive background in inference optimization for self-hosted architecture, focusing on throughput, latency, GPU metrics, quantization, and cost efficiency.
Skilled in rigorous model evaluation methods, such as offline benchmarks, online testing, human evaluations, and core product metrics.
Hands-on background utilizing multimodal models or large language models specifically for video use cases.
Familiarity working alongside video systems and architectures, including vision-language models, automated speech recognition and transcription, video understanding pipelines, and enhancement or upscaling tools.
Product-focused mindset capable of balancing operational reliability, cost, speed, and model quality.

Nice to Have

Background working with consumer video software, creator platforms, recommendation engines, content systems, or high-scale multimodal products.
