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 Hospitals lose billions annually to opaque payer rules and outdated contracts.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.

Apply: hiring@healthyrapport.com with resume or LinkedIn.

Please note we are unfortunately unable to sponsor visas or hire candidates outside of the US at this time.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
