Staff AI Product Engineer

Compensation: $150k – $220k • 0.5% – 1.5%

Deeply is building a Relationship Operating System for couples — an AI agent that helps couples turn what matters into shared understanding, constructive action, follow-through, and real relationship improvement.

We’re looking for an exceptional product engineer who wants to help invent the product, not just implement tickets.

What you’ll do

You’ll work across the stack: React/Next.js, backend/domain logic, Postgres/Supabase, AI agents, SMS, notifications, background jobs, memory, and product instrumentation.
