Nuclearn builds AI software purpose-built for nuclear power operations, deployed across 60+ reactors globally. The stack—Python, PyTorch, Kubernetes, React, FastAPI, PostgreSQL—reflects a modern ML-first architecture, but the project list reveals the real complexity: on-premise deployments, legacy system integration, real-time monitoring for mission-critical safety workflows, and high-dimensional ML visualization. Engineering hiring is decelerating despite active work on CAP automation, SaaS provisioning, and domain-specific ML pipelines, suggesting the team is consolidating around core product stability rather than scaling new features.
Nuclearn applies AI to nuclear power plant operations, addressing workflows traditionally managed with outdated tools. The company targets plant operators and safety teams, offering automation around corrective action program (CAP) screening, condition reporting, and operational monitoring. Founded in 2021 by nuclear professionals and engineers, Nuclearn operates as a distributed product across on-premise and SaaS deployment models, supporting both direct integrations with legacy plant systems (Maximo) and cloud-native instances. At 11–50 employees and headquartered in Phoenix, the team is anchored in nuclear domain expertise rather than generic software scaling.
Python, PyTorch, FastAPI, React, TypeScript, Kubernetes, PostgreSQL, MongoDB, Redis, and NVIDIA GPU for ML workloads. Includes Maximo integration for legacy nuclear plant systems and Sentry for error monitoring.
Over 60 reactors around the world rely on Nuclearn's technology for operations and safety workflows.
