<div> Who we are: Nitra's mission is to build a more efficient healthcare system and the technology that makes it possible. We built AI products that help doctors better manage their practices, so they can have time back to focus on what matters to them most. We are scaling rapidly and on a clear trajectory toward becoming a unicorn this year. We are building a category-defining company, and we’re looking for people who want to do the most meaningful work of their careers. If you want comfort, this isn’t the place. We operate with urgency, intensity, and ambition. If you want to take ownership in building a generational company, come join us. Nitra was created by unicorn founders, and joined by an experienced team from Microsoft, Meta, Plaid, PayPal, BCG, Morgan Stanley, and more. The team is backed by some of the world’s leading VCs (Andreessen Horowitz, NEA, etc.) and is supported by an expert group of advisors including the co-founders of Square, former Governors, and co-founder of CityMD.   We're looking for: A Senior Machine Learning Engineer to architect and build Nitra’s next-generation data and AI platform, powering intelligent products across healthcare and fintech. This role sits at the intersection of applied AI and platform engineering. You will design and deploy systems that enable internal agentic workflows (ex: GTM, product intelligence), while also contributing directly to customer-facing agentic systems (ex: revenue cycle management, care coordination, voice AI). We need someone who can operate across layers—from data pipelines and model infrastructure to shipping AI products that drive real-world outcomes for providers. </div> Your responsibilities will include: Data + AI Platform • Design and build scalable ML/AI infrastructure, including feature stores, model serving, data streaming, evaluation frameworks, and observability systems • Build and maintain data pipelines for structured and unstructured data (claims, EHR, transactions, logs) • Ensure data quality, lineage, and reliability across the platform • Ensure compliance and security for data handling, including adherence to healthcare and financial data standards • Empower teams to access data and turn into actionable insights with agentic analytics Applied Machine Learning • Prototype and productionize ML models for: • Anomaly detection (e.g., billing irregularities, operational outliers) • Predictive modeling (e.g., claims risk, fraud) • Build and deploy models across use cases like: • Revenue cycle management ( automated coding, denial management, prior auth) • Care coordination (clinical reasoning, workflow automation) • Establish and own best practices across MLOps and LLMOps, including: • Model lifecycle management (training, versioning, deployment, monitoring) • LLM evaluation, prompt/version control, and experimentation frameworks • CI/CD for ML systems and reproducible pipelines • Develop systems for LLM orchestration and agent frameworks (tool use, memory, retrieval, multi-step reasoning) • Understand drivers and implement solutions for agent performance, e.g. model selection, memory, context windows prompt engineering, agent orchestration, fine-tuning Product Collaboration • Partner closely with forward-deployed Product, Data Science, and GTM teams to translate ambiguous problems into production-ready AI systems • Own end-to-end delivery, from experimentation to deployment and iteration • Contribute to defining Nitra’s agentic AI product strategy Engineering Excellence • Establish best practices for model evaluation, monitoring, and safety • Improve system reliability, latency, and cost efficiency at scale • Mentor engineers and help raise the bar for ML across the team You have: Core Experience • 4+ years of experience in machine learning and data engineering • Strong background in ML frameworks for reinforcement learning • Hands-on experience with multi-agent systems, evaluation, and observability • Proven experience deploying ML systems into production at scale (think: $billions in volume) MLOps / LLMOps • Hands-on experience with MLOps practices, including: • Model versioning, monitoring, and retraining pipelines • Experiment tracking and reproducibility • Experience with LLMOps tooling and workflows, including: • Prompt management and evaluation • RAG systems and vector databases • LLM performance optimization (latency, cost, quality) Data Platform • Experience building data pipelines (batch + streaming) and working with large-scale datasets • Strong understanding of distributed systems and cloud infrastructure (AWS/GCP/Azure) • Familiarity with tools like Airflow, Spark, dbt, or similar Domain • Experience in healthcare, fintech, or other regulated environments is a plus • Understanding of data security, compliance, and privacy considerations (e.g., HIPAA, SOC2) Culture • Ability to work cross-functionally and communicate complex ideas clearly • Experience working closely with product and business stakeholders • High attention to detail with a bias toward action • Strong ownership mindset—you don’t just build models, you solve problems end-to-end We offer: • Equity - Everyone at Nitra is an owner.
