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\nAalo Atomics is seeking a Mechanical Cognizant System Engineer (CSE) to provide lifecycle technical ownership of assigned mechanical systems at the Critical Assembly Facility (CAF) on the Aalo-X site.\nInitial system assignments are expected to include the Critical Assembly Vessel (CAV) and Reactivity Control System (RCS).\nAs the CSE, you will be the technical owner of your assigned systems throughout their operating lifecycle - why they were designed as they were, what requirements they must meet, how they are configured, how they are performing, and what must be done when they are maintained, modified, or begin to degrade.\nYou will work closely with Operations, Maintenance, Nuclear Safety, QA, vendors, project engineers, and the Design Authority to keep assigned systems safe, reliable, correctly configured, and technically defensible.\nWhat you'll do\nCognizant System Engineering\nMaintain detailed technical knowledge of assigned system functions, design requirements, performance criteria, interfaces, operating limits, and current configuration, including traceability among requirements, physical configuration, safety-basis functions where applicable, and controlled documentation.\nServe as the principal engineering point of contact for assigned systems.\nMaintain System Design Descriptions, drawings, calculations, specifications, vendor information, technical evaluations, and applicable engineering inputs to procedures.\nMaintain awareness of system interfaces with electrical, I&C, structural, facility, and reactor systems.\nSystem Health & Performance Monitoring\nMonitor system health using surveillance results, inspection data, operating history, maintenance history, equipment condition, and field observations, and review test and surveillance results against approved design and performance requirements.\nTrend system parameters and equipment performance to identify degradation before required functionality is lost.\nPerform or support system walkdowns and material-condition assessments.\nIdentify recurring equipment issues and develop technically sound corrective actions.\nEscalate adverse trends or conditions that challenge system requirements or safety functions.\nOperations & Maintenance Support\nProvide engineering support for system operation, troubleshooting, maintenance, testing, and emergent equipment issues.\nSupply design-basis and technical input to maintenance work planning.\nEvaluate degraded and nonconforming conditions involving assigned systems, and support equipment-failure investigations, root-cause evaluations, and corrective actions.\nEstablish or review technical acceptance criteria for maintenance and modification testing.\nReview completed work and test results to verify restoration of required system configuration and performance.\nConfiguration & Change Management\nParticipate in change reviews affecting assigned systems.\nEvaluate changes for impacts to requirements, interfaces, performance, safety functions, documentation, testing, and equipment qualification.\nSupport USQ screening/evaluations by providing accurate technical information.\nSupport physical configuration walkdowns and reconcile discrepancies between field conditions and controlled documentation.\nSupport Engineering Change Requests and Engineering Change Notices through implementation and closure.\nEquipment Lifecycle & Procurement\nMonitor replacement-part availability and equipment obsolescence.\nDevelop or review technical requirements for replacement equipment and components.\nSupport equivalent-replacement and substitution evaluations.\nReview supplier and vendor technical information.\nModifications & Future Facilities\nSupport design, installation, testing, and turnover of modifications to assigned systems.\nParticipate in future Aalo-0 and Aalo-X reactor design reviews with emphasis on operability, maintainability, reliability, testability, and configuration control.\nSupport commissioning and turnover of new systems.\nAssume responsibility for additional systems as qualifications, workload, and organizational needs evolve.\nQualifications\nRequired\nBachelor's degree in Mechanical Engineering or closely related engineering discipline.\n5+ years of relevant engineering experience in nuclear power, DOE facilities, power generation, high-hazard industry, aerospace, petrochemical facilities, or another regulated environment.\nStrong mechanical system-engineering fundamentals.\nExperience supporting and troubleshooting operating mechanical equipment.\nAbility to interpret mechanical drawings, P&IDs, system descriptions, engineering calculations, specifications, and vendor documentation.\nExperience with mechanical equipment such as pressure boundaries, actuators, mechanical drives, valves, structures, or similar high-reliability equipment.\nStrong written and verbal technical communication skills.\nAbility to independently drive technical issues through resolution.\nPreferred\n10+ years of relevant mechanical or nuclear plant engineering experience.\nPrevious experience as a Cognizant System Engineer, System Engineer, Responsible System Engineer, or equivalent technical system owner.\nDOE nuclear-facility experience.\nFamiliarity with DOE-STD-1073 configuration-management principles.\nExperience with nuclear safety-classified or special-treatment SSCs.\nExperience with USQ processes, nuclear work control, design control, and corrective-action programs.\nExperience reviewing surveillance, inspection, or operational data for system-health purposes.\nKnowledge of applicable ASME, ASME B&PV, ASME B31, AWS, or other relevant engineering codes and standards.\nProfessional Engineer license.\nExperience with Teamcenter or comparable configuration/document-management systems.\nRequirements:\nBased in the United States\nWilling to work on-site in Idaho Falls, Idaho\nWhat We Offer:\nCompetitive salary based on technical level \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.
