Meet Radiance

The Source® of all your creative collateral.

Radiance is a digital design agency powered by The SOURCE®, a proprietary Creative OS that aligns every asset, message, and moment into one adaptive brand system.

We combine human-crafted design with intelligent systems to help modern brands operate with clarity, speed, and cohesion. Every engagement we deliver is not just creative output, but infrastructure: systems that scale as our clients grow.

At the center is The SOURCE®, a platform blending design, AI, and automation into a single evolving system for brand truth, execution, and growth.

We are backed by Infinity Constellation, the first AI holding company, and are building something category-defining at the intersection of brand, systems, and intelligence.

Why This Role Exists

Radiance is moving from services-first → platform-powered.

We are looking for a Senior Full Stack Engineer to help architect, build, and evolve The SOURCE® from a powerful internal system into a scalable platform that supports both our agency workflows and future SaaS expansion.

This is not a “ticket-taking” role.
This is a role for someone who wants to shape the product, the architecture, and the technical philosophy from the ground up.

You’ll work directly with the founder to translate creative workflows, brand logic, and operational complexity into elegant systems that compound over time.

Translate creative, brand, and agency workflows into scalable systems

Build a platform that supports services today and SaaS tomorrow

Execution & Systems

Build internal tools that reduce scope creep and operational drag

Integrate AI, automation, and workflow tooling where it actually adds value
