Senior Software Engineer Seattle, WA

The Nuclear Company is the fastest growing startup in the nuclear and energy space creating a never before seen fleet‑scale approach to building nuclear reactors. Through its design‑once, build‑many approach and coalition building across communities, regulators, and financial stakeholders, The Nuclear Company is committed to delivering safe and reliable electricity at the lowest cost, while catalyzing the nuclear industry toward rapid development in America and globally.

The Nuclear Company (TNC) is at the forefront of America’s nuclear renaissance, delivering the abundant, clean, reliable energy necessary for our nation to remain the world’s leader. We’re not just building nuclear plants – we’re revolutionizing how they’re built.

About the role

You will be instrumental in developing Nuclear OS, the first purpose‑built digital platform to digitize, automate, and streamline the development and deployment of fleet‑scale nuclear power plants. You’ll work directly with nuclear engineers, construction teams, and procurement specialists to build software that solves real‑world challenges in nuclear deployment.

Responsibilities

Core Development

• Design and implement key components of Nuclear OS, including data integration, AI/ML systems, and workflow automation

• Build secure, scalable systems that consolidate formerly siloed data (engineering plans, project schedules, supply‑chain information, quality records, sensor feeds) onto a single platform

• Develop advanced analytics and AI capabilities that enable unprecedented real‑time visibility and proactive control over complex nuclear projects

Cross‑Functional Collaboration

• Work closely with nuclear engineers, construction workers, quality foremen, and planning teams to understand their workflows and pain points

• Collaborate with field teams to ensure Nuclear OS addresses real construction challenges, not theoretical problems

• Partner with regulatory compliance teams to build automated workflow systems

Technical Excellence

• Implement foundational architecture that combines Palantir’s powerful data integration and modeling capabilities with nuclear‑specific functionality

• Ensure end‑to‑end system integration where improvements in one area immediately benefit all other areas through a common platform

• Build systems that are traceable, auditable, and compliant with nuclear industry standards

Innovation & Problem‑Solving

• Develop solutions for transmitting lessons learned from field installation back to nuclear reactor design authorities and sub‑vendors

• Create data‑centric requirement environments to interface with external parties while maintaining security and compliance

• Build segregated collaboration work spaces for partners with appropriate export control compliance
