What You'll Do

• Scope and lead ML initiatives end-to-end from identifying opportunities and defining the problem through production deployment and iteration
• Design, develop, and optimize ML models and AI systems for document parsing, extraction, classification, and intelligent automation
• Build and maintain production ML pipelines that are robust, observable, and scalable
• Integrate and fine-tune third-party AI services (OpenAI, Amazon Textract, cloud ML APIs), managing cost, latency, and quality tradeoffs
• Analyze datasets to uncover patterns, validate model performance, and generate actionable insights
• Help develop our AI roadmap, balancing key technical and product tradeoffs
• Drive architectural decisions for ML systems and establish best practices for development, evaluation, and deployment
• Teach and mentor members of the engineering team, constantly modeling how great ML software should be developed

Qualifications

• 8+ years of experience as a software engineer, with 4+ years focused on ML or applied AI in production environments
• Track record of shipping ML systems that deliver measurable business impact
• Strong proficiency in Python and the modern ML/AI stack (PyTorch, Hugging Face, scikit-learn, or similar)
• Experience with LLMs in production including fine-tuning, prompt engineering, RAG, and evaluation strategies
• Strong ability to work cross-functionally to help define, build, and deliver on product and tech objectives
• Experience mentoring and leading teams, ideally in a startup environment
• Care deeply about both technical success and product success
• Excellent communication skills

Requirements

• Experience with healthcare data, compliance workflows, or regulated industries
• Background in document understanding, OCR/ICR, or information extraction from unstructured data
• Hands-on experience with MLOps tooling (MLflow, W&B, Airflow) or cloud ML infrastructure (SageMaker, Vertex AI, Bedrock)
• Graduate work in a quantitative field (CS, statistics, ML, or related)
