Founding Senior AI/ML Engineer
San Francisco, South Park
Role Overview:
We are seeking a brilliant and experienced Founding AI/ML Engineer to help build & architect our platform's intelligence. You will be a cornerstone of a lean, talent-dense, and fast-moving engineering team in San Francisco. This is a unique opportunity to build a new generation of recommendation and personalization engines from the ground up, pioneering the systems that will make our product uniquely intelligent and engaging.
We’re building the world’s first proactive intelligence network — a consumer social platform that makes expert-level AI discoverable, interactive, and effortlessly useful. While AI is one of the most powerful tools ever created, it remains inaccessible to most people. Our mission is to give everyday users permissionless access to intelligence leverage through a simple, social, and proactive interface. We believe AI needs a new kind of interface — one that shifts from reactive, one-off prompts to anticipatory, multi-step workflows that feel intuitive, approachable, and even magical.
This is a zero-to-one opportunity to redefine how people interact with AI over the next decade. We're taking on challenges with no precedent — building a social graph for intelligence, designing AI-native user experiences, and shaping new consumer behavior on a global scale. We’re assembling a small, top-tier founding team of 10–12 engineers working from fully equipped, individual offices in South Park to create a product that blends psychology, recommendation systems, and cutting-edge AI into something truly transformative.
What You’ll Do
- Architect & Build: Own the end-to-end creation of our core recommendation and personalization engine. You will design the system architecture, select the right models and technologies, and build it from the ground up.
- Pioneer with LLMs: Move beyond traditional recommendation models by designing, fine-tuning, and implementing novel systems that leverage the latest advancements in Large Language Models (LLMs) to understand user intent and content nuance in deeply sophisticated ways.
- Develop Complex Systems: Engineer and deploy robust, scalable systems that intelligently combine multiple models (e.g., LLMs, GNNs, collaborative filtering) to create a world-class user experience.
- Lead Technical Strategy: Define the vision and roadmap for personalization, discovery, and recommendations across the platform. You will be the expert voice, making key decisions that shape the future of our product.
- Hands-On Modeling: From data processing and feature engineering to model training, evaluation, and deployment, you will be hands-on throughout the entire machine learning lifecycle.
- Establish MLOps: Build the foundational infrastructure for data pipelines, model training, A/B testing, and real-time inference to ensure our systems are reliable, scalable, and continuously improving.
- Collaborate & Influence: Work closely with product, design, and engineering leaders to translate user needs into technical solutions and drive the integration of AI/ML into our core product features.
- Design for Scale: Architect a robust, resilient, and highly available technical stack capable of supporting millions of users and capable of reliably scaling to #1 App Store spot.
