Perplexity is hiring a software engineer for its Training Infrastructure team, which runs large-scale reinforcement learning and agent evaluation platforms. The engineer will build distributed systems that schedule AI workloads across global compute and design interfaces and tools for launching experiments and reading results. The posting asks for at least two years shipping distributed systems for compute-intensive workloads, a backend language such as Python, Rust, C++ or Go, and familiarity with AWS, Kubernetes and ML infrastructure. The role combines full-stack engineering with research acceleration.
