Fabrion, San Francisco Bay Area
We’re hiring a founding full stack engineer to help architect and build the platform from day one. This is a unique opportunity to a significant portion of the tech stack and grow into a leadership role with considerable upside in equity.
You’ll be working on infrastructure that combines large-scale data systems with AI-native agents. This is a highly autonomous, high-leverage role with ownership over core architecture and early team culture.
You’ll be writing production code across backend and frontend, defining interfaces between components, shaping devops and data infrastructure, and helping translate abstract concepts into working systems. If you’re someone who prefers fast feedback, direct impact, and long-term upside — this is for you.
Location: San Francisco Bay Area Type: Full-Time Compensation: Competitive salary + meaningful equity (founding tier)
Backed by 8VC, we're building a world-class team to tackle one of the industry’s most critical infrastructure problems.
An ability to learn and grasp new technologies quickly trumps knowing the entire tech stack — you should be comfortable learning and adapting in a fast-moving environment. The following represents the types of technologies you will be working with:
Languages: TypeScript (Node.js), Python (FastAPI) Frontend: React, Next.js, Tailwind, shadcn/ui Backend: Postgres, DuckDB, GraphQL (Hasura), Kafka, REST Cloud/Infra: AWS, Docker, GitHub Actions, ArgoCD, Kubernetes (basic) AI/Agents: LangChain, LangGraph, OpenAI, Anthropic, LLaMA, Pinecone, Qdrant Governance: Keycloak, Open Policy Agent (OPA), OpenTelemetry, Slack integrations Visualization: Vega, Flourish, React ReChart Connectors: ERP, PLM, Excel, Email, Web APIs
If you want to build systems that learn, act, and evolve — with the autonomy to shape the stack and the team — we’d love to hear from you.
