Full Stack Software Engineer

Role Description

We’re hiring a Full Stack Software Engineer to build and scale the systems that power Goodbill — from massive healthcare data pipelines to seamless, consumer-grade member experiences.

• Build across the stack.
• Write both frontend and backend code daily. Our stack is Ruby, HTML, CSS, and JavaScript with Rails, SCSS, and Hotwire. Experience in these is great, but not required — what matters is excitement to work in this environment.
• Ship agentic AI features.
• Design and build AI-driven products and workflows with autonomous/agentic behavior. Bonus if you’ve built agentic AI products in production; barring that, you’ve played with personal projects and can show the spark.
• Work with diverse data sources.
• Maintain and further automate our existing hospital price data pipeline, and extend it with other sources: regulatory filings, government datasets, third-party APIs, EHR integrations, and even web scraping.
• Build consumer-grade experiences.
• Any member-facing software you touch needs to be seamless, fast, and delightful — because healthcare users deserve consumer-quality design.
• Own what you build.
• We believe no engineer should support code they can’t change. You’ll maintain the systems you write, and your teammates will do the same.

Qualifications

• Equally fluent in product and architecture.
• You sweat the details on pixels and abstractions — your code and your design decisions are elegant, intentional, and durable.
• Fast and fearless.
• Startups are a sprint and a marathon. You know when to hack, when to harden, and how to keep velocity high without sacrificing long-term quality.
• Agentic AI curious (and capable).
• You’ve built, or want to build, products that go beyond prompt-response — orchestration, planning loops, autonomous flows.
• Ground-floor ready.
• You’re energized by the idea that nothing exists until you build it. The hard parts don’t scare you; they motivate you.
• Collaborative.
• You’ll work closely with Product, Operations, Sales, and Client Success to ship features that move real dollars in the healthcare system.

Requirements

• Bonus: You’ve built and shipped agentic AI products in production (personal projects also count).
• Experience with EDI (Electronic Data Interchange) standards — X12, 837s/835s — is a plus, but not required.
• You’ve built in healthcare, fintech, or other regulated domains.
• You’ve worked in an early-stage startup (pre-seed/seed/Series A).

Benefits

• Competitive pay (cash and equity).
• Unlimited PTO (Seriously — it’s not an empty benefit. We work too hard for anything else.)
• Health, dental, and vision plans covered 100% for you and 50% for dependents.
• A monthly personal trainer through Future.
• Internet or co-working space stipend.
• Primary care membership stipend.
• Remote office equipment stipend.
• Quarterly team retreats.
