Senior Research Engineer

Basis Set is building the memory layer for AI agents, enabling them to remember conversations and learn from interactions. The Senior Research Engineer will own the lifecycle of memory features, fine-tuning models and collaborating with engineering to ensure 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
