Kairos Power
Company Overview
Kairos Power, LLC
Alameda, California, United States
2016
Approximately 300 employees (source: climatebase.org).
What They Do
Kairos Power is a pioneering American nuclear energy company that specializes in developing advanced nuclear reactor technology, specifically the fluoride salt-cooled high-temperature reactor (KP-FHR). This innovative reactor design utilizes TRISO (tri-structural isotropic) coated particle fuel in a buoyant annular graphite pebble form, combined with low-pressure Flibe (Li2BeF4 lithium-beryllium-fluoride salt) coolant. This technology allows for online refueling without the need for reactor shutdowns, high-temperature operations that exceed conventional fuel capabilities, and a secondary solar salt loop for steam generation, making it compatible with modern commercial power plants (source: kairospower.com). The company aims to provide cost-competitive energy solutions that feature high availability, low maintenance, and near-zero carbon emissions, positioning its reactors as a complementary energy source alongside variable renewables for enhanced grid resiliency (source: wikipedia.org). Target markets include U.S. electricity generation and process heat applications, particularly for data centers powering artificial intelligence, with plans for initial commercial offerings following successful demonstrations in the early 2030s (source: kairospower.com).
Projects & Track Record
While Kairos Power has not yet completed any full-scale commercial projects, it has made significant strides in testing and demonstration initiatives. The company has operated the RAPID Lab (R-Lab) in Alameda since September 2018, focusing on surrogate fluid and high-temperature materials testing. Additionally, the commissioning of the Salt Lab (S-Lab) in July 2020 has facilitated evaluations of Flibe coolant, while the Pebble Development Lab at KP Southwest was completed in May 2021. The Engineering Test Unit (ETU) has also made progress with hot commissioning starting in August 2022 (source: kairospower.consultation.ai). The flagship project currently underway is the Hermes low-power demonstration FHR reactor, which has a thermal capacity of 35 MW and is being developed in partnership with the Tennessee Valley Authority (TVA). Initial geotechnical work at the Oak Ridge, Tennessee site commenced in August 2021, and the NRC construction permit application was accepted for review in November 2021, with full construction permit approval achieved in December 2023 (source: wikipedia.org).
Recent Developments
In the past two years, Kairos Power has secured significant regulatory approvals, including the NRC site construction approval for the Hermes reactor in Tennessee in 2023, marking a historic milestone as the first such permit granted in 50 years for a non-water-cooled reactor. The full construction permit was also approved in December 2023, following extensive pre-application engagement that began in October 2018 (source: wikipedia.org). A major highlight for 2024 is the agreement with Google to deploy six to seven small nuclear reactors to power AI data centers, with the first unit expected to be operational by 2030 (source: wikipedia.org). Additionally, the ongoing partnership with the Department of Energy, which includes a $629 million cost-sharing award for the Hermes project, continues to support the company's development and licensing efforts (source: kairospower.consultation.ai).
Working There
Kairos Power actively hires across various engineering disciplines, including reactor and salt system design, analysis, testing, licensing, and manufacturing roles such as machining, welding, and fabrication. The company fosters a collaborative and hands-on work environment that emphasizes innovation and mission-driven objectives, with a culture that values diversity and inclusivity (source: kairospower.com). Active recruitment is ongoing at their headquarters in Alameda, California, as well as at their facilities in Albuquerque, New Mexico, which include manufacturing and testing labs (source: kairospower.consultation.ai). The company places a strong emphasis on mission statement reviews at the start of meetings to ensure alignment with their goal of facilitating the clean energy transition, and they attract talent passionate about making a significant impact in the world (source: kairospower.com). Specific employee benefits are not extensively detailed in public sources, but the company promotes a high-performance work environment that supports innovation (source: kairospower.com).

Job Description
Kairos Power is a new nuclear energy technology and engineering company whose mission is to enable the world's transition to clean energy, with the ultimate goal to dramatically improve people's quality of life while protecting the environment. This goal will be accomplished through the commercialization of the fluoride-salt-cooled, high-temperature reactor (FHR) that can be deployed with robust safety, affordable costs, and flexible operation to accommodate the expansion of variable renewables.
The Inventory Management System (IMS) team is seeking a highly motivated and passionate Engineer to join our efforts in designing, building, and commissioning high-temperature skids for molten salt systems. The ideal candidate will have a strong foundation in process, chemical, and mechanical engineering, with the ability to apply these skills to high-temperature design challenges.
In this role, you will contribute to the development of critical process systems for the Hermes reactor, our first-of-a-kind low-power nuclear demonstration reactor. As a key member of the IMS team, you will assist in designing, commissioning, and operating components to manage and control the reactor's molten salt coolant inventory. The position requires an aptitude for chemical engineering, systems integration, and industrial or pilot-scale system deployment. You will collaborate closely with mechanical design, plant layout, piping, instrumentation, and operations teams to integrate and optimize these systems.
Responsibilities
- Support design of high temperature piping loops, vessels, heaters, and instruments to manage the Hermes molten salt coolant inventory.
- Perform engineering calculations to support defining hydraulic, thermal, or other design parameters such as pipe size, required pump head, heat loss, hydraulic losses in a pipe loop, etc.
- Lead the design and construction of test platforms, including component prototypes, scaled system demonstrations, and engineering studies to inform IMS system design and performance.
- Develop and document engineering calculations, technical studies, and design rationale through clear and concise technical reports, memos, and presentations.
