What you'll do:

You'll write and ship full-stack features end to end, from frontend UI, to backend AI logic, to the database, and infra.

We're still a small team, and the product is early — you won't just be building features; you'll help shape the trajectory of the company and the future of AI development.

Here are a few examples of the kinds of things you might work on:

• Build a signal processor that turns unstructured data into actionable insights powered by AI Agents
• Create lightweight interface for sales leaders that surface confident actions with one-click workflows
• Design the core API for AI CRO brain: versioning insights, collaborative editing for revenue teams, powered by LLMs and fast iteration
• Talk to early users, debug live pipeline issues, ship fixes same-day
• Make product calls on ambiguity, unblock yourself, and own the stack from 01
• $your ideas here

Who You Are

Minimum

• 3+ years engineering, with a strong track record of shipping 01 products (Including time shipping production software)
• You've built and deployed agent-like systems; multi-step LLM pipelines, tool-using bots, scripted assistants, or similar.
• Fluent across the stack: backend APIs, frontend UIs, databases; end-to-end ownership
• RAG pipelines (e.g. embeddings, vector DBs, chunking strategies)
• Agent memory systems (e.g. scratchpads, history compression, summarization)
• Tool use and orchestration (e.g. calling real APIs, using plugins, auth flows)
• Evaluation — success metrics, regression testing, and improving agent behavior over time
• You write production-grade code and can work across systems without needing a spec.
• You thrive in fast-paced, product-first environments where the goal is shipping.
• Comfortable with startup ambiguity: unblock yourself, pragmatic trade-offs, no perfect specs needed
