Senior Research Engineer

Mem0 is building the memory layer for AI agents, allowing AI to remember conversations and learn from interactions. The Senior Research Engineer will own the end-to-end lifecycle of memory features, conducting research, prototyping, and shipping solutions to improve memory quality.

Responsibilities:

• Train models for memory extraction, updates, consolidation/forgetting, and conflict resolution. Iterate based on data and outcomes, not vibes
• Read, reproduce, and implement research. Quickly prototype paper ideas, benchmark against baselines, and productionize what wins
• Build evaluation at scale. Automated relevance/accuracy/consistency metrics, gold sets, online A/B and interleaving experiments, and clear dashboards
• Work closely with customers to uncover pain points, turn them into research hypotheses, and validate solutions through field trials
• Partner with Engineering to ship. Design APIs and data contracts, plan safe rollouts, and maintain low latency, high reliability, and reasonable cost at scale
