Responsibilities

Build POCs for real use cases: Stand up end-to-end demos (UI + APIs + data) that integrate Mem0 in the customer’s flow
Experiment with memory retrieval: Try different embeddings, indexing, hybrid search, re-ranking, chunking/windowing, prompts, and caching to hit task-level quality and latency targets
Prototype with Research: Implement paper ideas and new techniques from scratch, compare baselines, and keep what wins
Create eval harnesses: Define small gold sets and lightweight metrics to judge POC success; instrument demos with basic telemetry
Integrate AI tooling: Combine LLMs, vector DBs, Mem0 SDKs/APIs, and third-party services into coherent workflows
Collaborate tightly: Work with Backend on clean contracts and data models; with Research on hypotheses; share learnings and next steps
Package & handoff: Write concise docs, scripts, and templates so Engineering can productionize quickly
