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 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. 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 RADIANCE IS FOR YOU IF: - You want to build systems that compound - You enjoy shaping products from first principles - You care about how humans actually work, create, and decide - You like autonomy and responsibility more than structure - You want equity in what you build RADIANCE IS NOT FOR YOU IF: - You want highly defined specs and long planning cycles - You prefer maintaining existing systems over creating new ones - You’re looking for a narrow engineering role You’re uncomfortable with ambiguity or iteration
