About the Role

We’re hiring a Senior Software Engineer to own and deliver product features across RadiantGraph’s core application.

In this role, you’ll build real product functionality end-to-end - designing backend services and APIs, wiring them into the product UI, and shipping features that customers actively use. You’ll work on workflows that support customer outreach and engagement, integrate AI-driven decisioning into product surfaces, and improve systems that are already running in production.

This is a hands-on role for an engineer who is comfortable moving between backend and frontend to get work done, but who naturally thinks backend-first: data models, APIs, execution paths, and system behavior. You’ll collaborate closely with other senior and staff engineers, contributing to roadmap-critical work while maintaining high standards for reliability and clarity.

You’ll be successful here if you enjoy owning features, iterating quickly based on feedback, and working in a small team where shipping matters more than ceremony.

What You’ll Do

• Own and ship product features end-to-end, spanning backend services, APIs, and frontend UI.

• Implement frontend features in TypeScript/React (Next.js) to deliver complete product experiences.

• Translate product requirements into working software, balancing speed, quality, and maintainability.

• Contribute to system reliability by thinking through edge cases, data integrity, and failure modes.

• Collaborate closely with other engineers to integrate work cleanly across the stack.

• This is a HYBRID role in office 2-3 days a week.

Bonus Points

• Experience working on AI-enabled or data-driven product features.

• Exposure to healthcare, compliance-heavy, or regulated environments.

• Familiarity with AWS and production cloud deployments.

• Experience improving or extending an existing product rather than building greenfield only.
