AI Engineer II

We are building the next generation of hyper-personal AI systems that fundamentally transform how humans interact with businesses. Led by our Chief AI Scientist, the Personal Superintelligence Lab at Gopuff develops cutting-edge agentic AI solutions that reason about complex user contexts, preferences, and real-world constraints to deliver superhuman performance in personalized shopping assistance. You will advance the state-of-the-art in prediction, alignment, grounding, and multi-agent orchestration while deploying these breakthroughs at massive scale. You will own core components of our instant shopping personal intelligence—context engineering, grounding, alignment, and serving—so technology accelerates customers to their goals, leveraging our unparalleled delivery speed. You’ll design context engineering strategies and real‑time retrieval, build SFT pipelines, and implement reinforcement learning from human feedback (RLHF) and verifiable rewards (RLVR) using GRPO/GSPO. You’ll use relevant APIs for data augmentation and ship low‑latency, reliable inference (batching, caching, quantization, streaming) with strong observability and safety.
