Full Description

About Assembled Assembled builds the infrastructure that underpins exceptional customer support, empowering companies like CashApp, Etsy, and Robinhood to deliver faster, better service at scale. With solutions for workforce management, BPO collaboration, and AI-powered issue resolution, Assembled simplifies the complexities of modern support operations by uniting in-house, outsourced, and AI-powered agents in a single operating system. Backed by $70M in funding from NEA, Emergence Capital, and Stripe, and driven by a team of experts passionate about problem-solving, we’re at the forefront of support operations technology. The Team Our Agent Intelligence team is focused on maximizing AI agent performance and driving volume automation across voice, chat, and email channels. This team is vital for our vision of creating the ultimate omnichannel AI customer support agent and represents one of the fastest growing areas both inside our company and across the industry. We're currently one of the largest companies deploying AI agents in production at massive scale, working with enterprise clients like Canva, Etsy, and Ramp. The engineering challenges are significant and largely unsolved: building sophisticated evaluation systems, automating knowledge generation, optimizing AI agent accuracy, and creating the infrastructure needed to continuously improve agent intelligence at scale. Your Impact As part of the Agent Performance Engineering team, you'll be working on the core systems that make our AI agents smarter, more accurate, and more capable of handling complex customer interactions. You'll be building the evaluation frameworks, knowledge automation systems, and intelligence optimization tools that directly impact our ability to automate customer support at enterprise scale. Responsibilities Build foundational evaluation infrastructure: Develop comprehensive evaluation systems from the ground up, including golden dataset creation, automated benchmarking, and model comparison tools. You'll help create the frameworks that enable us to measure and optimize AI agent performance across all communication channels. Automate knowledge generation: Design and implement systems that automatically create synthetic guides, documentation, and metadata to improve agent knowledge bases. You'll work on cutting-edge approaches to knowledge extraction and augmentation. Optimize AI agent accuracy: Enhance our retrieval systems, implement advanced prompt optimization techniques, and build tools that continuously improve agent responses through automated evaluation and refinement. Develop intelligence infrastructure: Architect systems that enable rapid model upgrades, A/B testing of different AI approaches, and scalable evaluation pipelines that support enterprise deployment. Drive volume automation: Focus on the north star goal of maximizing automated resolutions across voice, chat, and email by building the intelligence systems that make it possible.
