Job description
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.
