Senior Applied AI/ML Engineer

ABOUT PIVOTAL HEALTH

Pivotal Health is the leading technology platform that helps healthcare providers get paid fairly in an increasingly complex reimbursement landscape.

Today, many providers face persistent underpayment from health insurance companies, despite delivering high-quality care. While processes like IDR (Independent Dispute Resolution) were designed to promote fairness, they’re often administrative-heavy, time-consuming, and difficult to navigate without the right tools.

Pivotal Health combines software, data, and service into a seamlessly integrated, AI-driven platform that simplifies these complex reimbursement workflows. We help providers efficiently dispute underpaid claims, reduce administrative burden, and recover the reimbursement they’re entitled to; without adding more work to already stretched teams.

Our full-service IDR solution is just the starting point. We’re building solutions that enable providers to operate with clarity, control, and confidence across the reimbursement journey.

ABOUT THE ROLE

We’re hiring a Senior Applied AI / ML Engineer to build and improve high-impact AI systems that sit directly in important product and operational workflows.

This role reports to the Head of AI/ML Engineering and is designed for someone who wants to work on applied systems, not research in isolation. You’ll operate at the intersection of models, software, product workflows, and business outcomes. Depending on team needs and your strengths, you may work on areas like document generation, dynamic offer engines and other next generation decisioning systems.

We are looking for product-oriented applied engineers who can move quickly, own meaningful surfaces, and turn ambiguous opportunities into shipped systems with measurable value. Some candidates may come from a classic ML engineering path. Others may come from data science-heavy environments where experimentation, optimization, decisioning, or marketplace dynamics were central. We’re open to both, as long as you are excited to ship.

We also want someone who is AI-first in their own work. The right person will use AI actively in engineering, analysis, iteration, debugging, and experimentation, and will help the team build a strong AI-native way of working.

WHAT YOU’LL DO

• Own and improve applied AI and ML systems that influence important business workflows.
• Build and refine production workflows around generation, decisioning, retrieval, evaluation, and orchestration.
• Work on concrete systems such as position statement generation, offer engine improvements, open negotiation agents, and configurable rules or decisioning systems.
• Design and run experiments that improve model quality, workflow quality, and business outcomes.
• Partner with product, operations, and engineering teammates to define success metrics and translate messy real-world problems into buildable systems.
• Improve prompt, model, and workflow behavior through tight feedback loops and practical iteration.
• Contribute to the engineering quality of these systems, including instrumentation, testing, rollout safety, and operational visibility.
• Use AI as a force multiplier in your own work and help the team move faster by bringing strong AI-native habits.
• Balance speed and rigor in an environment where shipping matters and iteration is constant.

WHAT SUCCESS LOOKS LIKE

In the first 6 to 12 months, strong outcomes in this role would include

• making clear improvements to position statement generation, offer engine behavior, open negotiation workflows, or related AI systems
• designing and running high-value experiments with real product or business impact
• reducing failure modes and increasing confidence in production AI workflows
• helping create stronger feedback loops between model behavior, operational workflows, and business outcomes
• becoming a trusted technical owner for an important applied AI surface
• contributing to a team culture that is both highly practical and highly capable with AI

WHO YOU ARE

• You are excited by applied AI and ML problems that sit close to product and business outcomes.
• You are strong technically, but you are not looking for a research-only role detached from shipping.
• You can work across experimentation, implementation, debugging, and productionization.
• You are comfortable with ambiguity and can move from rough opportunity to concrete execution quickly.
• You have a product-oriented mindset and care about whether a system is actually useful, not just whether it is technically interesting.
• You are an AI power user yourself and actively use AI in your day-to-day work with good judgment.
• You like operating in fast-moving environments where the feedback loop between work and impact is short.

WE’D BE ESPECIALLY EXCITED IF YOU HAVE

• experience with applied ML, LLM systems, agent workflows, or decisioning systems in production
• experience designing and interpreting experiments, evals, or optimization loops
• experience in domains like marketplaces, pricing, ad tech, credit decisioning, lending, or revenue optimization
• experience with retrieval, prompt engineering, structured generation, model routing, or tool-using agent workflows
• experience with Python and backend systems that support production AI workflows
• experience turning messy operational data and product requirements into shipped systems
• experience with healthcare or other operationally complex industries

WHY THIS ROLE IS INTERESTING

• The work is applied and consequential. These systems matter to core company workflows.
• You’ll have direct ownership over real AI surfaces, not just supporting infrastructure.
• The team is operating in a fast-moving window where a strong engineer can materially change outcomes in a short amount of time.
• The problems span models, prompts, systems, product, and operations, which makes the work unusually rich.
• We care about shipping, not just novelty.
• There is room for different strengths here, including stronger ML engineering profiles and stronger data science or optimization profiles, as long as you are excited to build.

EXAMPLE TECHNICAL ENVIRONMENT

Our current environment includes technologies and patterns like

• Python-based services and internal ML tooling
• FastAPI-backed product and platform services
• model evaluation and experimentation workflows
• LLM and agent systems grounded in structured internal data
• event-driven and workflow-oriented operational systems

You do not need to match this stack perfectly, but you should be comfortable learning quickly and shipping in this kind of environment.

WHY YOU’LL LOVE WORKING HERE

We’re a collaborative, low-ego team on a mission to make healthcare reimbursement fairer for providers. While we primarily hire around our core hubs–Los Angeles and New York–we remain open to exceptional talent outside those regions. Remote and hybrid flexibility varies by role and team, and is outlined in each job description.

If you’re excited by solving complex problems and making a real-world impact, we’d love to hear from you.

Benefits Include

• Competitive compensation, including equity
• Full health, dental, and vision coverage
• Retirement savings plan through 401(k)
• Flexible time off
• Opportunities for company-wide connection and events

Ready to Make an Impact?

We’re building something meaningful; and we want you on the team.

Bring your ideas, curiosity, and drive, and let’s transform healthcare reimbursement together.
