ChipAgents is revolutionizing chip design and verification with agentic-AI workflows. The company partners with top-10 semiconductor companies, hyperscale cloud providers, and cutting-edge startups to accelerate RTL development, functional verification, and simulation. You will improve the performance, reliability, and efficiency of AI agents for hardware applications. Your work spans identifying failure modes, designing and running evaluations, developing new agent capabilities, and turning successful experiments into production software. You'll collaborate with a growing team of software engineers, researchers, hardware experts, customers, and field teams across customer discovery, evaluation design, applied research, product development, and deployment. Key responsibilities include: - Identify failure modes in AI agents and design evaluations to measure and improve performance, reliability, and efficiency - Develop new agent capabilities and productionize successful experiments - Design effective evaluations based on customer and domain specialist interactions - Analyze traces and experimental results to identify bottlenecks - Develop tool interfaces, context-management systems, memory, and multi-step/multi-agent orchestration - Form clear hypotheses, test ideas quickly, and distinguish meaningful improvements from benchmark noise - Move fluidly between experimental work and pragmatic product engineering - Write well-architected, maintainable production code The role offers ownership of the software layer that turns cutting-edge ML research into scalable products at the intersection of AI and semiconductors. You'll work alongside industry veterans, real customers, and real production scale, shaping your scope across research collaboration, engineering, and customer-facing work based on your strengths.
