Senior Software Engineer, Product; Backend-Focused

About the Role

We’re hiring a Senior Software Engineer to own and deliver product features across Radiant Graph’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.
