Website: withradiance.com. Please apply using the provided form; candidates who email will not be considered.
Radiance is a digital design agency powered by The SOURCE, a Creative OS that learns and evolves with your brand. We combine human-crafted design with intelligent systems to help modern brands grow with clarity, creativity, and impact. Every project is crafted for long-term value — not just assets, but infrastructure. Radiance delivers bold creative backed by strategic insight, made to perform across media, commerce, and customer experience. The SOURCE powers design, AI, and automation in a single, adaptive system that grows with you.
Why this role exists: we’re looking for a sharp, systems-minded full-stack engineer who builds with urgency, curiosity, and care. You’ll partner directly with the founders to translate ideas, client feedback, and strategic needs into real, production-grade tools. This role is for someone who thrives in ambiguity, talks to users, and ships features that stick. As an early hire, you’ll help shape our foundational engineering principles and how we build as a team.
What You’ll Do
Architect and scale RAG pipelines, agent-based systems, and LLM-powered workflows
Fine-tune large language models for structured data extraction and automation
Build developer-friendly APIs and interfaces for web automation
Ship product features fast — with real usage and feedback
Work closely with the team and customers to build what matters
Stay ahead of the curve on LLM tools, embeddings, orchestration, and training
Create elegant, resilient systems that just work
What You Bring
Strong full-stack engineering experience (Python backend + Vue or equivalent frontend)
A systems mindset — architecture, UX, and scalability are one conversation to you
Hands-on familiarity with production-level AI tooling: prompt design, agents, vector DBs, etc.
Clear, proactive communication — you explain not just what you’re doing, but why
Autonomy — you move quickly and make things real
Pragmatism — you build what works, not just what’s elegant
Bonus Points
Built LLM-based agents, fine-tuned models, or designed RAG pipelines in production
Contributed to open-source projects in AI, ML, or developer infrastructure
Experience with AWS, Postgres, and scalable backend systems
Trained or fine-tuned foundation models from scratch or with custom data
Worked on web automation, scraping, or structured data extraction workflows
Why Join Radiance?
Founding seat — help define the product and shape how we build from the ground up
Fast feedback loop — internal users are power users, what you ship gets used
Design-forward culture — work alongside world-class strategists and brand thinkers
Remote-first, async-friendly — high trust, low overhead
Momentum — we ship features in days, not quarters
Competitive salary + meaningful equity
Backed by invisible.co, founded by repeat entrepreneurs
Interview Process
We keep things human, clear, and practical. The process includes a few conversations to get to know each other and either:
A short project (done on your own time, then discussed in a review call)
Or a collaborative working session, where we build something together
We’ll align on the format that works best for you.
Is Radiance for You?
You think in systems and love building from zero
You care about clean UX, smart architecture, and long-term impact
You want to work closely with founders and users to shape the product
You’re excited by creative tools, AI workflows, and fast iteration
You thrive in autonomy, take initiative, and move with purpose
Not for You
You need detailed specs and tightly scoped tasks
You prefer to stay in your lane and avoid user conversations
You’re not interested in design systems or GenAI
You’re optimizing for predictability over ownership
