Fabrion

Founding Engineer (Full Stack) Location: San Francisco Bay Area Type: Full-Time Compensation: Competitive salary + meaningful equity (founding tier) About the role We’re hiring a founding full stack engineer to help architect and build the platform from day one. This is a unique opportunity to own 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. Responsibilities Architect and build scalable APIs, backend services, and web application components Contribute across the stack: data pipelines, agents, web UIs, deployment systems Design and implement internal tooling, testing frameworks, and CI/CD pipelines Collaborate closely with product and design to prototype and ship features quickly Help define engineering processes, contribute to documentation, and grow the early team Our Stack 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 What We’re Looking For Experience 5+ years as a full stack or backend engineer Experience owning and delivering production systems end-to-end Prior experience with modern frontend frameworks (React, Next.js) Familiarity with building APIs, databases, cloud infrastructure, or deployment workflows at scale Comfortable working in early‑stage startups or autonomous roles; prior experience as a founder, founding engineer, or a 0‑1 pre‑seed startup is a big plus Mindset Comfortable with ambiguity, eager to prototype and iterate quickly Strong sense of ownership — prefers to build systems rather than wait for tickets Enjoys thinking about architecture, performance, and tradeoffs at every level Clear communicator and pragmatic team player Values equity and impact over prestige or hierarchy Prior startup or founding team experience Bonus Contributions to open‑source or internal tools with impact Interest in data systems, agent workflows, or LLM orchestration Why Join True ownership — early equity and influence over product and technical direction Mission‑driven team solving complex data and AI problems with real‑world impact Strong engineering culture focused on velocity, clarity, and long‑term thinking Learning curve across AI, data infra, agents, and enterprise‑scale platforms Early access to cutting‑edge AI workflows and deployment patterns 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.
