Clinical Video Annotator (Physical Therapist) - Contractor

At Sword, we’re building AI to heal billions and unlock humanity’s full potential. In doing so, we’re pioneering AI Care, a fundamentally new approach to healthcare built for medical reasoning, safety, and real-time treatment, not generic technology applied after the fact. As both a clinical-centric frontier AI lab and an applied AI platform, Sword is reimagining how care is delivered at scale, removing traditional barriers like appointments, waiting rooms, and stigma so more people can access the care they need—and ultimately get back to lives lived in full. Since 2020, Sword has expanded across physical therapy, women’s health, cardiometabolic, and mental health, and is now moving beyond the session to a fully AI-native, 24/7 care program that brings physical activity, therapeutic exercise, psychotherapy, nutrition, and behavior change into one connected experience. More than 700,000 members across three continents have completed over 10 million AI sessions, helping 1,000+ enterprise clients avoid more than $1 billion in unnecessary healthcare costs. Backed by 42 clinical studies, 44+ patents, and more than $500 million raised from leading investors including Khosla Ventures, General Catalyst, and Founders Fund, Sword is defining a new standard for healthcare. Role  Sword's AI models need to understand exercise quality the way a physical therapist does – not just whether a movement happened, but whether it was performed correctly, safely, and with adequate range of motion. Teaching an AI that requires human clinical judgment at scale. Your role is to watch recorded exercise sessions and provide structured clinical assessments that become the ground truth to evaluate and train our AI. This is high-volume, repetitive work – you will assess many videos per day using consistent criteria. Quality and consistency across high volume is what makes the data valuable. The Data & Tooling team produces the labeled datasets that power Sword's AI models. We build the training and evaluation data foundation that enables our AI to reason about human movement with clinical accuracy.
