Rapport | Founding AI Engineer + Founding Data Engineer | REMOTE (US) | Full-time | USD$160-220K+

Rapport is fixing healthcare's broken payment infrastructure. Hospitals lose billions annually to opaque payer rules and outdated contracts. We're an AI driven platform that ingests contracts, claims, and policies at scale, transforming them into real-time pricing intelligence to help get providers paid what they deserve.

We are backed by top tier investors and already have one of the largest RCM operators in the country as our development partner. Founded by a healthcare tech veteran with two prior exits. This is a chance to be a true founding team member with meaningful equity and direct impact on product and company direction.

Role 1: Founding AI Engineer – Claims Pricing Intelligence Build production pricing engines that transform messy healthcare data into accurate claim prices. Think of it like playing a complex game: interpret intricate payer rules, combine them into working logic, and validate at scale. Design data pipelines for PDFs/CSVs/APIs, create business logic combining rules based systems with ML validation, and build explainable systems where every decision is traceable. Thanks to our partnership, you'll work with massive real world datasets from day one. Stack: Python, SQL, FastAPI, LLMs and Agentic frameworks.

Role 2: Founding Data Engineer Architect our data platform from scratch. Build fault tolerant pipelines using Databricks that handle diverse sources, design normalization layers for healthcare data, and implement observability for production reliability. First data hire, you'll shape our entire data strategy. Stack: Python, SQL, Databricks, Azure/AWS, Airflow/Prefect.

Rapport is a remote only company with quarterly in person sessions. Significant equity + competitive compensation.

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)

Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.
