The Nuclear Company is the fastest growing AI tech-enabled startup in the nuclear and energy space, pioneering a fleet-scale approach to building the next generation of nuclear reactors. Through our design-once, build-many model, we're accelerating the deployment of safe, reliable, and affordable nuclear energy.

We operate with an AI-first mindset. Every employee is expected to leverage AI, technology, and the Nuclear Operating System (NOS) as integral components of their role to improve the quality, speed, and impact of their work. We expect every team member to continuously identify opportunities to automate workflows, enhance decision-making, improve processes, and contribute to the ongoing evolution of NOS as a strategic operating capability that enables The Nuclear Company to scale with excellence.

We hire people who are driven by purpose, thrive in ambiguity, and are energized by building what has never been built before. Our team combines intellectual curiosity with high agency, embraces candid feedback and continuous learning, and holds themselves and others to exceptional standards. Our values—Transparency, Responsibility, Unity, Scrappiness, and Tenacity—guide how we hire, collaborate, and make decisions every day. They are not words on a wall; they are the standard by which we operate. TRUST is the foundation of our safety culture, fostering intellectual honesty, accountability, and open communication, while our values challenge every team member to execute with urgency, humility, resilience, and an unwavering commitment to our mission.

About the role

As a Staff Software Engineer, you will serve as a technical leader responsible for architecting and delivering software that powers critical aspects of our nuclear energy platform. You'll work at the intersection of software, engineering, and operations, solving complex problems in a highly regulated environment where reliability and safety are paramount. This role requires both strategic thinking and hands-on execution, with opportunities to influence technical direction, mentor engineers, and drive cross-functional initiatives. Your work will directly contribute to advancing clean, carbon-free energy solutions and shaping the future of the nuclear industry.

Software Design & Development: Lead the design and development of robust, scalable, and high-quality software solutions for critical nuclear energy applications. This includes architecting new features, writing clean and efficient code, and participating in code reviews.
Technical Leadership: Provide technical leadership and guidance to junior and mid-level engineers, mentoring them in best practices for software development, quality, and adherence to industry standards.
System Integration: Work closely with hardware engineers, control systems engineers, and other software teams to ensure seamless integration of software components with physical systems and external interfaces.
Quality & Compliance: Implement and advocate for rigorous software quality assurance practices, including comprehensive testing, debugging, and documentation, ensuring compliance with nuclear industry regulations and internal quality standards.
Performance Optimization: Identify and resolve complex performance issues, ensuring our software operates efficiently and reliably under demanding conditions.
Problem Solving: Tackle challenging technical problems, proposing innovative solutions and driving their implementation from concept to deployment.
Documentation: Create and maintain thorough technical documentation, including design specifications, architecture diagrams, and testing protocols.

Experience

Bachelor's degree in Computer Science, Software Engineering, Electrical Engineering, or a closely related technical field.
7+ years of progressive experience in software development, with a strong portfolio of successfully delivered projects.
Experience developing software for highly regulated, safety-critical, or mission-critical industries (e.g., nuclear, aerospace, defense, medical devices, automotive safety). Direct nuclear industry experience is highly preferred.
Proficiency in one or more relevant programming languages such as JavaScript, TypeScript, or Python.
Demonstrated experience with full software development life cycles (SDLCs), including Agile and Waterfall methodologies.
Strong understanding of software design patterns, data structures, and algorithms.
Experience with version control systems (e.g., Git) and collaborative development workflows.
Expertise in designing and implementing complex software architectures.
Deep understanding of software quality assurance principles and testing methodologies.
Ability to debug and troubleshoot intricate software systems.
Exceptional problem-solving and analytical skills.
Strong written and verbal communication skills, with the ability to articulate technical concepts to diverse audiences.
Ability to work effectively in a collaborative, fast-paced environment.

Preferred Exerience

Experience building offline-capable, air-gapped, or otherwise disconnected applications, and packaging them for constrained or containerized deployment environments.
Hands-on experience integrating third-party physical security systems.
Experience applying AI features & ML models into production workflows.
Exposure to nuclear, critical infrastructure, defense, or physical security domains.
