infinity-constellation - Full Stack Engineer - Radiance
Requirements
• 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 • 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: • 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 • Iterate with live users (your team first) • Make tradeoffs without paralysis • 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
Responsibilities
• 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
Benefits
• Radiance is moving from services-first → platform-powered. • We are looking for a 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. • 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
