Founding Engineer

What we're building & role:

Source is building middleware and tools to help creators protect, structure, and trace their content across the web and AI systems. We're blending cybersecurity, web infrastructure, and adversarial LLM research to give creators control — and make their work more valuable to models via ontologies, enrichment, and agent-aware metadata. We're VC backed and looking for a Founding Engineer (full-stack or backend-leaning) who’s excited about the future of the creator economy, adversarial AI, and secure, content-aware infrastructure.

Stack:

• Python (PyTorch, HF Transformers, Pillow, Selenium/Chromium, Puppeteer, Playwright)
• Next.js + TypeScript
• Edge compute (Cloudflare Workers, Lambda@Edge)
• LLM ontologies, KGs, RAG / VectorDBs, JSON-LD, CodeAgents, MCP

If you’re into building systems that stand up for creators and enrich content for the age of AI, we’d love to talk.
