Company Overview 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. Job Summary The Reactor Vessel Auxiliary Systems team is seeking a highly motivated Senior Engineer to join the growing Reactor Systems department where you will have the opportunity to work directly on the design, integration, and assembly of the structures, systems, and components (SSCs) within the reactor cavity in a first-of-a-kind FHR. In this role, you will manage and coordinate the detailed layout of reactor cavity components including routing of fuel, salt, and gas lines from the reactor vessel through the bio-shield, locating remote handling accessible instrumentation, and standardizing common components and features. The position requires a strong aptitude for mechanical design, systems engineering, and high temperature components under irradiation. You will regularly interface with multi-disciplinary teams including nuclear design, civil structures, remote handling, reactor coolant auxiliary systems, reactor systems, safety analysis, instrumentation & controls, and plant design integration. You will work closely with these teams to implement component and instrumentation standardization, collaborate on SSC design, and develop a cavity layout that meets safety analysis, construction, and maintenance requirements for FHR demonstration reactors. Responsibilities Own and manage the 3D layout and spatial integration of all components within the reactor cavity including reactor vessel and support systems, instrumentation, shielding, and maintenance interfaces. Coordinate with mechanical, civil, and I&C design teams to define spatial, thermal, and functional interfaces between the reactor vessel, cavity systems, and bio-shield. Lead design integration reviews to ensure structures, systems, and component designs are compatible and accessible for installation and maintenance. Develop and implement standardized layouts, component interfaces, and remote maintenance connection strategies to streamline manufacturing, assembly, and maintenance operations. Regularly interface and communicate component requirements with other disciplinary teams including nuclear design, reactor systems, reactor coolant auxiliary systems, safety analysis, remote handling, and manufacturing. Perform design verification and validation activities to ensure system performance meets functional and safety requirements. Participate in hazard and failure analyses (HAZOP, FMEA, FTA) and incorporate safety insights into design iterations. Contribute to configuration management by maintaining design baselines, revision control, and traceability of changes. Participate in peer design reviews and technical audits to ensure compliance with quality and performance objectives. Other duties as assigned. Qualifications Bachelor’s or advanced degree in Mechanical, Nuclear, or Systems Engineering (or related discipline). 5+ years of experience in nuclear plant design, system integration or complex facility layout. Proven ability to lead cross-disciplinary integration and resolve technical and spatial conflicts. Demonstrated experience in system integration, equipment layout and standardization, and 3D CAD model management. Experience in reactor component fabrication and life cycle management processes including equipment qualification, in-service inspection, and other programs. Experience with configuration management systems or PLM tools. Experience with prototype or test rig development for mechanical systems. Experience working to a quality standard, such as ASME NQA-1 or ISO 9001. Knowledge, Skills & Abilities Familiarity with applicable codes and standards such as ASME B&PV Section VIII Division 1 and 2, and Section III Division 5. Proficiency in 3D CAD design and tools (e.g., SolidWorks, AVEVA or equivalent) and engineering analysis tools for thermal and structural modeling Knowledge of FEA and CFD methods and ability to apply results to mechanical design decisions Ability to interpret and apply industry standards and codes (ASME, ANSI, ASTM, ASME BPVC) Knowledge of system safety and reliability analysis methods such as FMEA and HAZOP Knowledge of configuration management and design control processes Experience with design and analysis of high-temperature and/or molten salt-wetted components under irradiation is a plus Ability to apply systems-thinking to evaluate interdependencies across reactor subsystems Strong analytical problem-solving abilities to resolve complex design issues efficiently Flexibility to consistently deliver tangible results in a rapid and dynamic work environment Self-motivated with strong time management skills and ownership mentality Capability to mentor and train junior engineers and interns. Excellent verbal, written communication/presentation, and interpersonal skills Ability to work with highly collaborative team Ability to solve problems quickly and efficiently Prioritizes and ensures safety of oneself and others Ability to proactively collect, manage and transfer knowledge Ability to seek different and novel ways to create efficiencies when working on problems, challenges and issues Physical Conditions Remaining in a stationary position, often standing or sitting, for prolonged periods Adjusting, moving, transporting, installing, positioning, or removing objects up to 30 pounds in all directions.

Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
