About Paddox Paddox Technologies is an AI company building a digital workforce. We build digital employees: AI workers that onboard, earn credentials, and take a seat on the org chart, working the same surfaces your team already uses. Instead of another tool bolted onto the side of the business, a Paddox digital employee is built into the org. It holds a role, reports up, and logs every action it takes. We deploy across the industries that run the real economy, from hospitality floors to engineering teams to enterprise operations.

The role Paddox digital employees run on a platform that turns a frontier model into a working hire: identity, memory, tools, and governance. As a Software Engineer on this platform, you will build the systems that let a digital employee onboard, hold a role, act across real software, and stay accountable for everything it does. You will work end to end, from the data model to the surfaces managers use, in a small team with real ownership.

What you'll do Build and ship full-stack features across the platform: Next.js and TypeScript on the front end, a Node and Postgres backend on Supabase, deployed on Google Cloud (Cloud Run). Develop the agent layer: reasoning, tool use, and routing built on LLM APIs (Anthropic, OpenAI) and modern agent frameworks. Implement memory scoped per role and per client, over Postgres and a vector store, with strict isolation between clients. Connect digital employees to the tools people already use, through APIs and MCP where they exist and browser or virtual-desktop automation where they do not. Build the governance layer: action logs, evaluations against the role, and human approval checkpoints. Integrate communication channels: email, chat, and voice.

What we're looking for You have shipped production software end to end and can show it (GitHub, live products, or references). Strong across the modern web stack: TypeScript, React and Next.js, Node, and a SQL database. Comfortable with cloud deployment and building against third-party APIs. You pick up new tools fast and own problems until they are solved. Clear communicator who forms opinions and voices them.

Nice to have Experience building with LLM APIs, agents, RAG, or vector databases. Experience with Google Cloud, Supabase, or MCP. Prior work on an early-stage or fast-moving product team.
