Senior AI Engineer, Prior Authorization
Posted on November 24, 2025 (4 minutes ago)
Arbiter is the AI-powered care orchestration system that unites healthcare. Today, healthcare runs on $100B+ in fragmented point solutions that can't see the full picture. We replace them with a single intelligent system that sits on top of EMRs and existing workflows, unifies clinical, policy, and financial data, then automates the actions that close care gaps - starting with site-of-care optimization.
Our Engineering Culture & Values
We are a high-performing group of engineers dedicated to delivering innovative, high-quality solutions to our clients and business partners. We believe in:
- Engineering Excellence: Taking immense pride in our technical craft and the products we build, treating both with utmost respect and care.
- Impact-Driven Development: Firmly committed to engineering high-quality, fault-tolerant, and highly scalable systems that evolve seamlessly with business needs, minimizing disruption.
- Collaboration Over Ego: Valuing exceptional work and groundbreaking ideas above all else. We seek talented individuals who are accustomed to working in a fast-paced environment and are driven to ship often to achieve significant impact.
- Continuous Growth: Fostering an environment of continuous learning, mentorship, and professional development, where you can deepen your expertise and grow your career.
Responsibilities
As a Senior AI Engineer, Prior Authorization, you will be instrumental in bringing our advanced data science models to life and building sophisticated agentic AI systems for the clinical domain:
- Model Productionization: Lead the engineering efforts to take cutting-edge data science models from research and development to scalable, production-ready systems, ensuring robustness, performance, and reliability.
- Agentic AI Development: Design, develop, and deploy intelligent AI agents and multi-agent systems using frameworks like Google ADK, LangChain, and LangGraph. These agents will automate complex clinical and administrative workflows, such as streamlining provider-facing prior authorization, detecting missed HCC codes, surfacing quality gaps, prompting compliant CPT submissions, and automating patient outreach.
- System Architecture: Contribute to the architectural design of our AI-driven operating system, focusing on modularity, scalability, and integration points for AI services within our broader platform and into existing partner workflows (e.g., EHRs).
- Performance & Reliability: Ensure the high performance, low latency, and fault tolerance of AI agents and inference pipelines, critical for real-time decision support and automated actions.
- Cross-Functional Collaboration: Work closely with data scientists, clinical domain experts, product managers, and other engineering teams to translate complex clinical problems into AI solutions that augment and work lock-step with expert human reviewers, and integrate them seamlessly into the Arbiter platform.
- Mentorship & Innovation: Actively mentor junior AI engineers, contribute to our internal knowledge base, and stay abreast of the latest advancements in AI, machine learning, and agentic systems to continuously innovate our offerings.
- Hiring & Onboarding: Participate in interviewing and onboarding new team members, helping to grow a world-class AI engineering organization.
Minimum Qualifications
- 8+ years of deep, hands-on experience in AI Engineering, Machine Learning Engineering, MLOps, or a closely related field, with a strong focus on productionizing models.
- Exceptional proficiency in Python for building complex AI systems and data pipelines.
- Demonstrated experience designing, building, and deploying AI agents and multi-agent systems using frameworks like LangChain, LangGraph, or similar agent orchestration tools. Experience with retrieval-based agents (e.g., leveraging LTM, case-based reasoning) is a strong plus.
- Profound understanding and hands-on experience with cloud-native AI/ML platforms, especially Google Cloud Platform (GCP) services (e.g., Vertex AI, BigQuery ML, Dataflow).
- Experience building systems for prior authorization workflows in healthcare.
- Basic understanding of machine learning algorithms, model training, evaluation, and inference.
- Intimate knowledge of and ability to implement unit, integration, and functional testing strategies.
- Experience providing technical leadership and guidance, and thinking strategically and analytically to solve problems.
- Friendly communication skills and ability to work well in a diverse team setting.
- Demonstrated experience working with many cross-functional partners.
- Demonstrated experience leading a software product or component vision and delivery plan.
Preferred Qualifications
- Familiarity with Google ADK for AI development and deployment.
- Direct experience working with Large Language Models (LLMs) and their application in real-world systems.
- Knowledge of MLOps principles, including CI/CD for ML, model monitoring, versioning, and explainability.
- Proven track record of building semi-autonomous AI systems that augment expert users (e.g., human-in-the-loop for clinical review) and embed natively into their workflows.
- Experience with unstructured data processing (e.g., natural language processing for clinical notes), including the use of sentence transformer embedding models.
- Contributions to open-source AI/ML projects or relevant publications.
This role can be remote or onsite, based in our New York City or Boca Raton offices, in a fast-paced, collaborative environment where great ideas move quickly from whiteboard to production.
