Full Stack Engineer – AI
Role
We are looking for a Full Stack Engineer - AI Systems to build the product layer that turns these capabilities into usable, production-grade workflows. This includes designing how agents operate, fail, recover, and deliver consistent value to users.

Build end-to-end product features across frontend, backend, and AI integrations
•
Design agent workflows that handle planning, tool use, failure, and recovery across multiple steps.
•
Integrate LLMs, memory, and external tools into systems that behave reliably under real-world conditions
•
Design real-time AI interactions with streaming, partial results, and tight latency constraints
•
Improve system reliability, observability, and fallback mechanisms
•
Collaborate closely with ML, backend, and product teams to ship features end-to-end
•
Continuously iterate based on real usage and failure modes
