Lead, Annotation Quality & Performance

Frontera Health is revolutionizing pediatric healthcare by developing a cutting-edge, tech-enabled platform that delivers essential therapies to rural families. Our platform leverages AI/ML to create a robust video-based data model for early intervention and developmental disorders. By collaborating closely with parents, caregivers, and clinical partners, we’re bridging the gap in access to care, improving health equity, and providing personalized treatment plans. Backed by leading investors like Lightspeed and Lux, Frontera Health is poised for rapid growth.

Our ABA direct services are designed to meet the unique needs of children in underserved communities, providing them with the support and resources they require to reach their full potential. We are passionate about ensuring that every child, regardless of their location or socioeconomic status, has access to high-quality healthcare. By leveraging our technology platform and partnering with local providers, we are able to deliver effective ABA therapy to families who may otherwise have limited access to these essential services.

Frontera Health is seeking a Clinical QA & Performance Lead to build and lead the quality systems behind our clinical annotation function. This team is responsible for labeling high-fidelity behavioral health data (video, audio, and text) that directly powers our AI models and clinical product insights.

This role is equal parts quality architect, measurement analyst, and clinical systems thinker. You’ll define what “good” looks like, build processes to track it, and ensure that the work we produce meets our clinical and scientific bar. You’ll work closely with our Ops, ML, and Clinical teams to ensure that ambiguity is resolved quickly, feedback is integrated thoughtfully, and performance continuously improves.

This is a hands-on leadership role with room to shape the future of clinical data quality at Frontera.

What You’ll Do

• Own definition and implementation of quality metrics (IOA / inter-rater agreement, audit scores, reviewer calibration)
• Build and maintain gold-standard datasets to serve as training and validation anchors
• Design QA workflows that balance precision, scale, and reviewer experience
• Lead reviewer onboarding and training systems, including calibration exercises and ongoing development
• Track performance across annotators and reviewers; flag drift and recommend coaching or retraining
• Partner closely with Ops Manager to align QA expectations with throughput goals
  Serve as a bridge between clinical subject matter experts, ML teams, and annotators to clarify labeling standards
• Monitor quality trends over time and drive continuous process improvement
• Facilitate periodic audits and synthesize findings into actionable recommendations
  
  

What You’ll Bring

• 4+ years experience in clinical QA, annotation QA, clinical operations, or healthcare analytics
• Familiarity with behavioral health, healthcare research, or human-annotated datasets
• Strong understanding of IOA/IRR concepts and metrics (e.g., Cohen’s or Fleiss’ kappa)
• Experience building or managing QA systems in data labeling, research, or clinical settings
• Analytical mindset with comfort using tools to track trends, measure performance, and drive change
• Excellent communication and training skills—able to support both junior annotators and senior stakeholders
• Thoughtful, systems-oriented approach to ambiguity, edge cases, and clinical nuance
• Bonus: Experience with tools like Label Studio or working in an ML-adjacent environment
