Job Description
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 Founding Product & Engineering Lead 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 foundational builder 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.
What You’ll Do
Platform & Product Architecture
Design and own the technical architecture of The SOURCE®
Translate creative, brand, and agency workflows into scalable systems
Build a platform that supports services today and SaaS tomorrow
Make pragmatic decisions about build vs buy vs automate
Execution & Systems
Ship fast, iterate often, and prioritize leverage over perfection
Build internal tools that reduce scope creep and operational drag
Integrate AI, automation, and workflow tooling where it actually adds value
Establish technical standards, documentation, and patterns early
Partnership & Leadership
Act as a thought partner to the founder on product vision and sequencing
Help define what Radiance should and should not build
Lay the groundwork for future engineering hires and contributors
Own outcomes, not just code
What You Bring
6–12+ years experience in engineering, product, or technical architecture roles
Experience building platforms or internal systems from zero to v1 (or beyond)
Strong product intuition: you think in systems, not features
Comfort working in ambiguity with evolving requirements
Ability to translate non-technical needs into technical solutions
Pragmatic, opinionated, and execution-focused
Experience with modern web stacks, APIs, automation, and AI tooling
Bias toward leverage, simplicity, and compounding value
MUST-HAVE HARD SKILLS (Non-Negotiable)
1. Full-Stack Web Development (Production-Grade)
Frontend: React / Next.js (or equivalent modern framework)
Backend: Node.js / Python (FastAPI preferred) or similar
REST + basic GraphQL understanding
Authentication, permissions, role-based access
Handling real users, real data, real edge cases
2. Systems Thinking & Data Modeling
Designing relational and/or hybrid schemas (Postgres + JSON)
Modeling entities like:
Brands
Assets
Campaigns
Messaging hierarchies
Versions / approvals / history
Understanding how systems evolve without breaking
3. Workflow Automation & Tool Integration
Integrate tools via APIs (Stripe, Jira, Webflow, CMSs, CRMs)
Use automation tools (Zapier, Make, n8n, Temporal, etc.)
Design async workflows (approvals, handoffs, notifications)
Build internal dashboards and admin tools
4. AI / LLM Practical Implementation
Prompt engineering for structured outputs
Embedding LLMs into workflows
Using vector databases (Pinecone, Weaviate, Supabase, etc.)
Designing guardrails for brand voice + consistency
Knowing when NOT to use AI
5. Shipping Mentality
Scope ruthlessly
Ship v1 fast
Iterate with live users (your team first)
Make tradeoffs without paralysis
Bonus Points
Experience building tools for agencies, creative teams, or knowledge workers
Exposure to AI workflows, LLMs, or automation systems
Experience scaling internal tools into external-facing products
Interest in brand, design, storytelling, or creative systems
Prior founding or early-employee experience
Why Join Radiance
Founding technical seat in a platform-led creative company
Direct influence on product, architecture, and company direction
Build something that blends brand, creativity, and intelligence
Move fast without corporate drag
Remote-first, async-friendly, outcomes-driven culture
Backed by Infinity Constellation with long-term ambition
