Job Summary
The problem
Administrative teams make hundreds of small decisions every day - approvals classifications routing follow-ups. Not complex individually but collectively they eat entire workdays. No tool solves this well because the hard part isnt automation - its judgment.
Were building an AI agent that doesnt just follow scripts but learns from how a team works prepares decisions executes autonomously where appropriate and gets meaningfully better over time through structured feedback. A virtual colleague that prepares and takes over repetitive tasks.
The product exists as a solid UX prototype and architectural direction. Now were looking for the person to shape and build it.
The role
Youll work directly with the Product Lead. No middlemen no ticket ping-pong. You get context you make decisions and you see the impact of your work within days.
The interesting part of this role isnt frontend polish its the stuff underneath. How does the agent decide when its confident enough to act on its own vs. when to ask a human How do you turn messy user corrections into structured learning signals without overfitting to one persons preferences How do you evaluate whether the system is actually getting better and catch it when its not
Youll spend your time building a full-stack app with the underlying agent orchestration knowledge logic feedback loops and evaluation pipelines.
Tasks
What youll build
- A new product from the ground up using a modern AI stack
- Autonomous AI agents that identify plan and execute tasks
- Agent steering logic deciding what to do when to act when to escalate
- Evaluation and validation frameworks to measure whether the agent is actually getting smarter
- Human-in-the-loop workflows where the AI prepares and the human decides
- APIs database logic and deployment pipelines
Your first weeks
In your first two weeks youll dig into the concept challenge assumptions discuss the best architecture and start building the first vertical slice of the agent pipeline. By week six youll have shaped core architectural decisions and shipped something real users can interact with.
Requirements
Must-have
- Youve built a system where AI agents autonomously plan and execute tasks
- Experience with React and (App Router Server Components)
