Founding Member of Technical Staff

TierZero AI is revolutionizing how engineering teams manage code in production, aiming to enhance incident response and operational visibility. As a founding team member, you will help build core products and systems, collaborating with leadership and customers to design AI systems and contribute to product experiences. Responsibilities: Design and implement agentic AI systems that reason about large sets of unstructured data; Ship full-stack features with direct user feedback; Contribute to the product experience so agents aren’t just smart, but usable and trusted by engineers; Build systems to automatically evaluate LLM outputs and improve agentic reasoning through self-play and feedback loops; Construct ML pipelines, including data ingestion, feature generation, embedding stores, RAG pipelines, vector search infra, and graph databases; Explore and prototype with open-source and frontier LLMs to evaluate tradeoffs; Build scalable infra to support long-running multi-step agents, including memory, state management, and async workflows; Participate in everything from company strategy to customer calls to office snacks Qualifications: 5+ years of working experience or open-source experience; Product-minded and customer-first thinking; Thrive in ambiguity; Interested in working with LLMs, MCPs, Cloud Infrastructures, and Observability tools; Willing to be in-person 3 days a week in our San Francisco office Required Skills: Large Language Models (LLMs), Cloud Infrastructure, Observability tools, Agentic AI systems, Full-stack development, Machine Learning pipelines, Data ingestion, Feature generation, Embedding stores, Retrieval-Augmented Generation (RAG) pipelines, Vector search infrastructure, Graph databases, Scalable infrastructure for multi-step agents, Memory, State management, Asynchronous workflows, Open-source LLMs, Applied research in AI, Distributed systems, Real-time data pipelines, Product-minded thinking, Adaptability to ambiguity, Customer-first mindset
