Ensuring that AI interacts with humans reliably, accurately, and empathetically at scale is where the real challenge lies. As the QA Lead, AI Agent , you will be the ultimate guardian of the customer experience for our AI Agent product line. This role is perfect for a strategic quality expert who loves the intersection of human psychology and machine logic. You will own the end-to-end quality strategy, from designing complex test plans for non-deterministic LLMs to building automated and scalable testing environments using Cresta's proprietary no-code test and evaluation tools. You aren't just looking for bugs; you are building the framework that allows Cresta to deploy world-class AI agents for the world's largest enterprises with total confidence. What You’ll Do: Architect & Scale AI Evaluation Systems: Design and oversee the end-to-end framework for testing AI agent systems at scale. You will leverage LLM-driven methodologies—including automated simulations, "LLM-on-LLM" rubrics, and adversarial red-teaming—to ensure reliability, policy adherence, and logic across complex, multi-turn conversational flows. Drive Deployment Excellence: Partner with Forward Deployed Engineers and PMs to triage issues, identify bottlenecks, and create new test cases on the fly to address real-world deployment challenges. Be the Customer’s Voice: Conduct manual UAT and voice-call testing to represent the end-customer experience. You take it personally when an agent lacks empathy or clarity, and you excel at articulating these nuances to the engineering team and clients. Lead and Scale the Team: lead a pod of QA analysts and partners. You will define the best practices, communication loops, and shared knowledge base that allow the QA function to scale alongside our rapidly growing product line. What We’re Looking For: 5+ years of experience in Quality Engineering, Deployments, or Technical QA, ideally within an AI or high-growth SaaS environment. Systems Thinking: A strong technical intuition and curiosity about how LLMs work. While you don't need to code, you must be comfortable navigating technical concepts like LLM, RAG, prompt logic, and multi-turn conversational flows. Operational Leadership: Proven ability to large E2E technical projects through partners, and a passion for building processes that improve efficiency between QA, Engineering, and Product. The "QA Nose": An uncanny ability to find the edge case and a bias toward action. You anticipate bottlenecks before they happen and deliver solutions with urgency. High Empathy: A consultative mindset with the ability to represent the "human element" of a customer support interaction. Startup Agility: You thrive in fast-paced environments, excel at turning ambiguity into execution, and are comfortable "rolling up your sleeves" to build. Bonus Points: Experience with CCaaS (Contact Center as a Service), telephony, or STT/TTS (Speech-to-Text) technologies. Background in Conversation Design or SDET roles. Experience leading team with direct reports. Perks & Benefits: We offer a comprehensive and people-first benefits package to support you at work and in life: Comprehensive medical, dental, and vision coverage with plans to fit you and your family Flexible PTO to take the time you need, when you need it Paid parental leave for all new parents welcoming a new child Retirement savings plan to help you plan for the future Remote work setup budget to help you create a productive home office Monthly wellness and communication stipend to keep you connected and balanced In-office meal program and commuter benefits provided for onsite employees Compensation at Cresta: Cresta’s approach to compensation is simple: recognize impact, reward excellence, and invest in our people. We offer competitive, location-based pay that reflects the market and what each individual brings to the table. Compensation for this position includes a Base salary + Bonus + Equity. Actual base salaries will be based on candidate-specific factors, including experience, skillset, and location, and local minimum pay requirements as applicable. Your recruiter can provide further details. In addition, total compensation includes a comprehensive benefits package for you and your family.
