## Description

Currently at $8M+ ARR and scaling rapidly, the organization is deep in the development of its next-generation platform-a step change in the capabilities of AI agents. The backend is the core of this transformation, processing millions of signals to facilitate autonomous decision-making. Our client is seeking a Staff Software Engineer to serve in a foundational role, owning major segments of the platform infrastructure and driving high-throughput AI orchestration. The engineering culture is flat, high-velocity, and results-oriented. There is no red tape; engineers are expected to own outcomes end-to-end, from architecture and design to deployment and monitoring., * AI Orchestration: Design and build the high-throughput pipelines and services that allow autonomous agents to process massive volumes of data and make reliable, real-time decisions

 * Platform Infrastructure: Own significant portions of a unified product stack that replaces traditional sales tools, including email infrastructure, CRM integrations, lead databases, and campaign engines
 * End-to-End Ownership: Take full accountability for the lifecycle of features-designing, building, deploying, and monitoring services without a separation between architecture and implementation
 * Rapid Iteration: Ship code constantly in a continuous release environment, maintaining high velocity while ensuring system stability
 * Technical Leadership: Contribute to the technical roadmap, mentor peers, and maintain high standards for reliability, observability, and testing across a distributed system
