Our mission is to make nuclear energy globally accessible, starting with the Aalo-1, a 10 MWe reactor leveraging cutting-edge safety, modularity, and efficiency. Based in Austin, TX, we’re rapidly growing as we work to deploy the world’s first fleet of advanced microreactors. Join us and help revolutionize energy for a sustainable future.\nAbout the role\nThe Senior Reactor Operator (SRO) operates and supervises operation of Aalo-X from the control room under the direction of the Shift Manager. The SRO monitors reactor and plant conditions, directs assigned operators, performs and verifies reactivity manipulations, responds to abnormal and emergency conditions, and provides the technical operating depth required for safe startup, testing, power operation, shutdown, and maintenance. Expectations are lead by example, own the role, and most importantly, value your team.\nWhat you'll do\nOperate or direct operation of the reactor, primary and secondary sodium systems, power-conversion systems, electrical distribution, support systems, and associated balance-of-plant equipment.\nPerform or supervise startups, shutdowns, power changes, reactivity manipulations, testing, surveillance, equipment operation, and abnormal/emergency response within qualification and delegated authority.\nOversee plant maintenance and testing operations to ensure safety and compliance.\nParticipate in design reviews and provide input to inform design as the end user.\nMaintain continuous awareness of reactor power, reactivity balance, heat transport, sodium-system parameters, alarms, trends, equipment status, and operating limits.\nRecognize adverse trends, equipment degradation, unexpected response, and margin erosion; communicate promptly and recommend conservative action.\nApply procedure use and adherence, place-keeping, three-way communication, peer checks, independent verification, component identification, formal briefings, and disciplined turnover.\nReview clearances, work packages, surveillance instructions, tests, temporary instructions, and restoration plans for operational impact.\nIdentify potential operability, configuration, safety-basis, or USQ concerns and ensure work is paused and elevated for formal review.\nCoach operators and participate in initial and continuing training, simulator scenarios, drills, examinations, qualification boards, and procedure validation.\nSupport event fact-finding, critiques, causal analysis, corrective actions, and operating-experience reviews with candor and complete records.\nQualifications\nHigh school diploma or equivalent.\nFive or more years of nuclear reactor operations experience.\nCurrent or previously held NRC Senior Reactor Operator license strongly preferred. An NRC Reactor Operator license, DOE SRO certification with substantial control-room experience, or Navy Reactor Operator with EOOW experience may be considered.\nCommercial nuclear control-room experience is strongly preferred.\nDemonstrated knowledge of reactor theory, thermodynamics, heat transfer, electrical generation, instrumentation and controls, reactivity management, operating limits, and abnormal/emergency response.\nAbility to complete Aalo-X facility-specific SRO qualification, including fundamentals, systems, procedures, simulator, written examination, operating test, oral board, and in-plant performance evaluations.\nStartup, commissioning, sodium-cooled reactor, advanced reactor, instructor, simulator, or procedure-validation experience preferred.\nRequirements:\nBased in the United States\nWilling to work on-site in Idaho Falls, ID\nWilling to work rotating shifts, nights, weekends, holidays, outages, and emergent call-ins\nAble to obtain and maintain required access authorization, medical/fitness-for-duty status, and company qualifications\nWhat We Offer:\nCompetitive salary\nHealth, Dental, Vision Insurance\nPaid Time Off\nCorporate Gym Membership\nAdditional Information:\nAalo Atomics provides a collaborative and supportive work environment, opportunities for professional growth, intellectually challenging careers, and competitive compensation.
