Software Engineer, Infrastructure, Applied AI

Job description

Meta is seeking experienced engineers to help deliver on one of the most ambitious goals in technology: personal superintelligence for everyone. As an engineer in the Applied AI Engineering (AAI) organization, you will apply your deep domain expertise, engineering skills, and sound judgment to make our frontier LLMs highly performant on real-world tasks. You will identify gaps in current model capabilities and build the complex systems, agentic pipelines, reinforcement learning environments, and evaluations that generate high-quality training signals. Working closely with Meta Superintelligence Labs, AAI contributes to advancing Meta's frontier models and AI products. We deliberately operate like an early-stage company: a flat, AI-native organization with light processes, wide scope, and fast decisions. We are looking for engineers with solid fundamentals in systems design, algorithms, and software engineering and AI fluency who are energized by ambiguity and by advancing Meta's frontier AI capabilities.
