You'll own products end to end, from customer discovery through shipped software, working across backend systems, LLM agents, frontend, and infrastructure.

What You'll Do

• Talk to ingredient manufacturers to understand their workflows and translate them into product.
• Build backend systems that ingest and process documents from customer ERPs and inboxes.
• Develop LLM agents that complete complex, multi-page compliance and food safety documents.
• Own products across the full stack, from problem definition through UI, and pick up whatever the company needs next.
• Ship fast and iterate on real user feedback rather than over-architecting.

What We're Looking For

• Product manager who learned to code, or a sole/first product engineer who owned a product end to end.
• At least 4 years of professional engineering experience with substantial hands‑on work.
• Proven product sense: you've shipped products real people used, talk to users regularly, and can articulate tradeoffs.
• Full‑stack capability to move features from backend through UI without waiting for specialists.
