Senior Software Engineer

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.
Our Strategic Advantage: Nuclear OS will be built by the team that will use it. No other effort in the industry is embedding its technology staff alongside the engineering, procurement and construction teams responsible for execution. Others attempt to build software from the outside, disconnected from the realities of nuclear deployment. The Nuclear Company is building a system designed from the inside — ensuring Nuclear OS will address the challenges that have stalled nuclear projects for decades.

About the Role

As a Senior Software Engineer, 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 workspaces for partners with appropriate export control compliance.

Experience

• Technical Skills
  • 5+ years of software engineering experience with expertise in cloud‑native architectures, distributed systems, data integration and ETL pipelines, AI/ML frameworks and model deployment, API design, microservices architecture, and DevSecOps practices and CI/CD pipelines.
  • Proficiency in modern programming languages (Python, Java, TypeScript, etc.).
  • Experience with database technologies (SQL and NoSQL).
  • Knowledge of containerization and orchestration (Docker, Kubernetes).
• Industry Experience
  • Experience building enterprise software for complex, regulated industries.
  • Understanding of project management workflows and construction processes.
  • Familiarity with quality assurance and compliance systems.
  • Experience with secure software development practices.
• Collaboration & Communication
  • Strong problem‑solving skills with ability to work in cross‑functional teams.
  • Experience translating business requirements into technical solutions.
  • Ability to work effectively with non‑technical stakeholders.
  • Excellent written and verbal communication skills.

Preferred Qualifications

• Bachelor’s degree in Computer Science, Engineering, or related field.
• Experience in nuclear, aerospace, defense, or other highly regulated industries.
• Familiarity with Palantir technologies or similar data integration platforms.
• Knowledge of construction management or industrial project execution.
• Experience with regulatory compliance systems.
• Security clearance eligibility.

Benefits

• Competitive compensation packages.
• 401k with company match.
• Medical, dental, vision plans.
• Generous vacation policy, plus holidays.
• Annual company retreats.
