Senior Backend Engineer, AI Systems & Architecture

## About the company Parker is the marketing brain for every business in the world. We launched in February and went viral. Parker now advises on over $1 billion in annual ad spend across hundreds of brands, including some of the largest consumer companies in the world. See our launch here: https://x.com/heyparkerdotai/status/2016221027093905561?s=20 See our website here: https://heyparker.ai/ It's never been easier to start a business. But attention is limited. Every business owner alive is fighting for the same shrinking pool of customer attention, and most of them are losing. They guess at messaging. They copy competitors. They burn cash on ads that die in three days. They have no idea what their customers actually want to hear. Parker sits in the middle of that fight. We help business owners win attention efficiently across paid, organic, retention, forecasting — every surface of the marketing funnel. The marketing function at every company on earth is our addressable surface area. If we win this position, Parker is a generational company. The work spans the deepest parts of the technical stack and the deepest parts of human psychology, at the same time. On the technical side, we're building agentic AI systems that ingest millions of signals — customer reviews, ad performance data, organic content, comments, transcripts — and turn them into creative that converts. We're doing original research to imbue our models with real creative taste. Not just pattern-matching on customer language, but internalizing the principles of great creative strategy. We want Parker to have judgment, not just recall. On the psychology side, we're studying what actually moves people. Why a phrase like "dad bod" sells more jeans than "athletic fit." Why some ads stop the scroll and others die. The work sits at the intersection of LLM research, marketing science, and consumer behavior, and almost no one is operating at this intersection seriously. The team behind Parker is rare: top engineers, world-class creative strategists, and seasoned ad agency operators all under one roof. We're venture backed by top firms in Silicon Valley, including OVO Fund, Unlock VP, and Hustle Fund, alongside operators from OpenAI, Anthropic, Meta, Google, and Vercel. ## The vision for this role This is a deep IC role for an engineer who loves designing systems and lives in the code. You'll architect and build the core systems that make Parker work — agent orchestration, data pipelines, eval harnesses, memory systems, the infrastructure that holds it all up. The center of gravity is backend, but you ship features end-to-end, frontend included. Parker today is great. Parker tomorrow is true AI agent orchestration — autonomous agents that research customer trends, write ad strategy, generate creative, run tests, and double down on what's working, all in concert. No human in the loop except to set direction. Most of the industry is still gluing together prompts and calling it an agent. We're
