AI Engineer II

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 intelligencecontext engineering, grounding, alignment, and servingso 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. In close partnership with Engineering and Data Science, you'll run experiments end-to-end and deliver production models that drive measurable lifts in business KPI under privacy-by-design and rigorous evaluation.

Benefits Overview

The only predictable thing about life is that it's wildly unpredictable. That's where we come in. When life does what it does best, customers turn to Gopuff to deliver their everyday essentials, and to get through their day & night, work day and weekend. We're assembling a team of thinkers, dreamers & risk-takers...the kind of people who know the value of peace of mind in an unpredictable world. (And people who love snacks.) Like what you're hearing?
