How to apply for Distinguished Engineer, Reactor Systems

About Kairos Power

Kairos Power is at the forefront of advanced nuclear technology, developing fluoride-salt-cooled, high-temperature reactors (KP-FHR) to provide clean, affordable energy. Their focus on iterative design and rapid prototyping, combined with a mission to accelerate global clean energy transition, makes them a unique and impactful place to work.

About the role

As a Distinguished Engineer for Reactor Systems, you will define the technical vision and architecture for the reactor's core systems, ensuring safety, performance, and manufacturability. This role is pivotal in leading cross-disciplinary teams and resolving complex engineering challenges that directly shape the deployment of next-generation nuclear reactors.

A typical day

You might start by reviewing design progress with your team, then lead a technical review of integration challenges between the reactor core and heat transport system. Afternoon could involve a cross-functional meeting with manufacturing and safety teams to align on qualification plans, followed by strategic discussions on long-term architecture.

Who Kairos Power is looking for

• A recognized technical authority with 20+ years of progressive leadership in nuclear reactor design, specifically in reactor systems engineering or similarly regulated environments.
• Deep expertise in fluoride-salt-cooled or high-temperature reactor technologies, with a proven track record of developing and deploying complex engineered systems.
• Extensive experience with applicable codes and standards (e.g., ASME, NRC regulations) and a history of resolving cross-disciplinary issues.
• Strategic thinker who can establish long-term technical vision while providing hands-on leadership in design, analysis, testing, and qualification.

Tips for this application

• Highlight specific contributions to advanced reactor projects, especially those involving fluoride-salt or high-temperature designs. Quantify impact (e.g., improved safety margins, reduced costs).
• Emphasize your experience with regulatory interactions and code compliance (ASME, NRC). Mention any direct involvement in licensing or safety analysis.
• Showcase leadership in cross-functional teams—describe how you resolved complex technical disputes and set architectural direction.
• Tailor your resume to reflect the company's focus on iterative design and rapid prototyping. Use keywords like 'integration,' 'qualification,' and 'deployment.'
• Include a brief statement in your cover letter about your alignment with Kairos Power's mission to accelerate clean energy transition.

What to cover in your cover letter

['Your technical authority in reactor systems, with concrete examples of leading design and integration for advanced reactors.', "Experience with fluoride-salt or high-temperature coolant technologies and how you've addressed unique challenges (e.g., material compatibility, thermal hydraulics).", "Your strategic vision for reactor system architecture and how it aligns with Kairos Power's goals for safety, manufacturability, and deployment.", 'Ability to mentor and lead senior engineers while fostering a culture of innovation and technical excellence.']

Research before applying

• Review Kairos Power's published technical reports and presentations on KP-FHR design, especially on thermal hydraulics and materials.
• Study their approach to iterative design and prototyping, as highlighted in their company blog or news articles.
• Understand their regulatory strategy—how they engage with the NRC for advanced reactor licensing.
• Familiarize yourself with their leadership team and recent milestones (e.g., construction of Hermes test reactor).

Likely interview topics

Based on the job description, expect questions about:

• Describe a time you resolved a critical cross-disciplinary technical issue in reactor design. How did you balance safety, performance, and cost?
• How would you approach establishing the long-term technical vision for reactor systems at Kairos Power?
• What experience do you have with fluoride-salt coolant systems, and what are the key design challenges?
• Discuss your familiarity with ASME Section III and NRC regulatory requirements for advanced reactors.
• How do you ensure that design decisions consider manufacturability and maintainability from the outset?

Common mistakes to avoid

• Avoid generic statements about nuclear engineering without specific reference to advanced reactors or salt-cooled technology.
• Don't downplay the importance of codes and standards—this role demands deep regulatory knowledge.
• Avoid being too theoretical; emphasize practical experience with design, testing, and deployment.
