Founding Software Engineer | Platform at Railway Health Inc. – New York, New York

ArloAt Arlo, we're transforming health insurance for small and medium-sized businesses across the U.S. Our mission is to make healthcare more affordable and long-term-oriented by driving innovation at every level of health plan design.
2024 marked our breakthrough year: we hit profitability, found strong market fit, and brought affordable healthcare to more than 200 businesses and their employees.
We’re a small but mighty team bringing wide-ranging expertise:

• Developing mission-critical software at Palantir
• Scaling a Y Combinator startup from the very first hire to Series A (50+ employees)
• Creating actuarial models used by major health insurers
• Leading patient operations teams at a high-growth health plan startup

RoleAt Arlo, we’re rebuilding health insurance for people who are fed up with the status quo. As our Founding Platform Engineer, you’ll architect the systems that power everything from real-time health insurance quotes to patient-facing tools that make care more transparent, affordable, and human.
You’ll work across infrastructure, data, and ML interfaces — giving patients upfront pricing before doctor visits, brokers smart quoting tools, and our team modern internal systems powered by LLMs.
Some things you might build:

• Quoting Infrastructure – High-performance APIs that crunch millions of data points to generate accurate, real-time insurance quotes.
• Financial Intelligence Engine – Systems that trace the source of premium payments across ACH rails and auto-engage late payers with smart nudges.
• Patient-Facing Cost Transparency Tools – Infrastructure behind our patient apps that show members exactly what they’ll owe before every visit.
• LLM-Powered Ops + Outreach – Internal platforms and workflows that use LLMs to reduce manual work and communicate with brokers and patients in smarter, more personalized ways.

You’ll have high ownership, operate in a fast-moving environment, and be core to how we make healthcare radically simpler and more patient-first.

Be efficient: You show an interest in using the best tool for the job. Our current favorites are Python, Postgres, Typescript, React, and other AWS services for our infrastructure.
