You will translate creative workflows into technical systems, define product architecture, and drive the transition from services to a SaaS model. ## 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 1. 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 1. 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 1. 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 1. 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 ## About Infinity ## Company Overview - **One-liner**: Infinity Constellation is the first AI services holding company that builds category-defining AI-native businesses from scratch to disrupt the $9T+ professional services market. - **Entity Type**: Private (Seed stage) - **Headquarters**: Las Vegas, Nevada, United States - **Founded**: 2023 - **Founders**: Brennan Pothetes (CEO) and Francis Pedraza (President & Chairman) ## Core Business - **Primary industry/industries**: AI Services / Holding Company / Professional Services - **Target customers**: B2B; End customers of its portfolio companies (legal, finance, consulting, executive assistance) and the founder-operators it recruits to build those companies - **Mission or purpose statement**: “Build, don’t buy.” — Reinventing how category-defining businesses are built and consumed, with AI-native companies that deliver outcomes from day one. ## Products & Services Infinity Constellation incubates and launches independent portfolio companies under one shared infrastructure. Known subsidiaries include: - **Supernal**: AI Employee Services — AI-native workforce and business process solutions - **Everest**: Executive Assistant Services — AI-augmented executive and personal assistant support - **Labrynth**: Data and Analytics Services — AI-driven data insights and analytics - **Paradox Machines**: Data and Analytics Services - **Radiance**: Design services (Associate Designer roles listed) Each operates as “AI-native from day zero,” combining founder-operators with applied AI engineers to replace traditional professional service delivery. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed (conflicting reports; total funding indicates seed-stage valuation) - **Key Metric – Total Funding**: $12.0M (Seed round, closed June 27, 2025) - **Notable Investors/Partners**: Round led by **Freestyle Capital**; notable board members include **Eduardo Tamraz**, **Doug Clinton**, **Charlie Songhurst** - **Growth Signals**: - Headcount growth: +188.9% YoY (from ~4 to 21 employees in one year) - Claims “as fast as 2 months to $1M ARR” and “1 month to first revenue” for incubated companies - Operating in 5 countries: United States, Kenya, Pakistan, Bangladesh, Ghana - 20 active job postings across portfolio companies - Recent quarterly job posting growth: +66.7% ## Competitive Advantages - **Shared Brain Model**: Data, pricing, and know-how flow across every company instead of being siloed in one team — compounding advantages with each new build - **Speed**: Pre-built infrastructure (finance, legal, HR, ops, GTM playbooks) gives founder-CEOs a 12-month head start over independent startups - **No Acquisition Strategy**: Builds from day zero — no layoffs, no integration risk, no cultural debt - **Repeat Founders + AI Engineers**: Combines proven operators with world-class applied AI engineers in every portfolio company ## Strategic Focus - **Scale the Constellation**: Continue launching new AI-native professional services companies across legal, finance, accounting, consulting, and beyond - **Compounding by Design**: Each new company makes the next cheaper, faster, and smarter to build - **Displacement of Incumbents**: Target the $9T+ professional services market, replacing 200-year-old service models with AI-first delivery - **Stay Lean**: Aggressively use AI and automation to keep headcount minimal; hire only when there’s no alternative ## Why Work Here - **Culture highlights**: The company explicitly defines its culture through a set of published principles: “Speed Over Perfection,” “Aggressive Yet Kind,” “Our Word Is Our Bond,” “Move Fast,” “Tell Us the Truth,” and “Figure It Out.” Emphasis on high standards, direct feedback, and extreme ownership without bureaucracy. - **Remote/hybrid/office policy**: Mostly remote-first across the US (many jobs marked “Remote, USA”); physical HQ in New York, but employees work from home; some roles in Las Vegas - **Notable perks or engineering culture**: Access to a shared brain across the portfolio — playbooks, customer intros, and lessons from every company; founders get back-office leverage so they focus on product and customers; engineering roles involve building AI-native products from scratch using cutting-edge applied AI - **Who thrives here**: Self-starters who move fast, ship real products, iterate quickly, and want to be part of building category-defining businesses rather than maintaining existing ones - **Known downsides from culture page**: High expectations — “We push hard. We have high standards.” — and a rejection of perfectionism: “Paralysis is worse than a wrong call you can reverse.” ## Sources 1.
