Senior Backend Engineer_Hybrid; NYC

We are looking for a Senior Backend Engineer to join a fast-moving applied AI and data analytics company as one of their highest-priority hires. The focus is twofold: architecting the platform to sustain significantly increased enterprise usage, and building innovative new features with decisions that hold up for years. This is a DRI (Directly Responsible Individual) role — you will own systems end-to-end, from graph database layer to API infrastructure to data pipelines  sweet spot is someone senior enough to think architecturally, but still energized by hands‑on implementation.

The platform connects an organization's entire data landscape — internal systems, social media trends, industry reports, consumer behavior signals — into a single coherent intelligence layer that surfaces insights and automates workflows that used to take analysts weeks. At its core is a production graph RAG system connecting temporal and sentiment data at enterprise scale — a key technical differentiator. As a senior backend IC, you will work across the graph database layer, API infrastructure, and data pipelines with concurrency  will collaborate with ML/AI engineers to bring predictive and prescriptive models into production, own system reliability under high‑throughput conditions, and shape the long‑term technical trajectory of the platform.

There is currently a staff backend engineer working across large parts of the stack — you will be additive senior capacity, not a replacement.
