Senior Research Engineer

Mem0 is building the memory layer for AI agents, enabling them to remember conversations and learn from interactions. They are seeking a Senior Research Engineer to own the end-to-end lifecycle of memory features, fine-tuning models and collaborating with engineering to ensure high performance and reliability.

Responsibilities:

• Fine-tune and train models for memory extraction, updates, consolidation/forgetting, and conflict resolution; iterate based on data and outcomes
• 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 & interleaving, 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 SOTA latency, reliability, and cost at scale
