Backend Engineer: US & Canada

WE'RE BUILDING A NEW HEALTHCARE CLEARINGHOUSE

The company is the only headless clearinghouse and RCM engine. Headless means every part of our product is accessible via API. Developers and AI agents build their own interface on top of it. By offering modern, AI-ready APIs alongside traditional real-time and batch EDI processes, we enable both healthcare technology businesses and established players to exchange mission-critical transactions. Our clearinghouse product and customer-first approach have set us apart. The company was ranked by Ramp [link for members] as one of the fastest-growing SaaS vendors.

The company has lightning in a bottle: engineers and designers shipping products week in and week out; a lean business team supporting the company's infrastructure; a passion for automation and eliminating toil; and $142 million in funding from top investors like Stripe, Addition, USV, Bloomberg Beta, First Round Capital, and more.

WHAT WE’RE LOOKING FOR

The company is the world's only programmable healthcare clearinghouse. By offering a modern API interface for running eligibility checks, processing claims, and ingesting ERAs, healthcare technology businesses can exchange transactions with payers without dealing with the EDI protocol or carrier-specific connectivity.

As we continue to scale, we are looking for an experienced backend engineer to join our engineering team to build our healthcare APIs and extend existing systems.

HOW WE BUILD

• We use AWS exclusively for our customer-facing backend infrastructure. We use tools like GitHub, Stripe, and PagerDuty, but all of our application work happens on AWS.

• We use serverless technologies almost exclusively: Lambda, API Gateway, SQS, SNS, DynamoDB, Aurora Serverless,  and more. We don’t run a single server.

• We use CDK (TypeScript) to define infrastructure as code.

• We write the majority of our API backends and EDI parsing engine in Rust.

WHAT YOU'LL DO

• Design and develop complex, large-scale web applications and APIs

• Work closely with AWS to improve our understanding and use of their services

• Contribute to a culture of engineering excellence and rigor through both coding and writing high-quality, effective communication

• Build the highest quality, broadest-reaching commercial trading network at the lowest possible price for our customers

WHO YOU ARE

• 4+ years of coding experience, previous work in Rust and TypeScript is beneficial

• 4+ years working with AWS services

• Committed to working with AWS serverless offerings in a production environment

• Ability to prioritize your work based on the needs of the business and the customers

• High bandwidth; thoughtful attention to many areas simultaneously

• Ability to context switch throughout the course of the day or week as priorities shift

• Philosophical alignment with the company Standards [link for members]
