Mechanical Cognizant System Engineer

Aalo Atomics is pioneering a new era in clean energy with factory-fabricated microreactors designed to deliver affordable, scalable, and reliable nuclear power. 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.

Aalo 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.

Initial system assignments are expected to include the Critical Assembly Vessel (CAV) and Reactivity Control System (RCS).

As 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.

You 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.

• Maintain 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.
• Serve as the principal engineering point of contact for assigned systems.
• Maintain System Design Descriptions, drawings, calculations, specifications, vendor information, technical evaluations, and applicable engineering inputs to procedures.
• Maintain awareness of system interfaces with electrical, I&C, structural, facility, and reactor systems.

• Monitor 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.
• Trend system parameters and equipment performance to identify degradation before required functionality is lost.
• Perform or support system walkdowns and material-condition assessments.
• Identify recurring equipment issues and develop technically sound corrective actions.
• Escalate adverse trends or conditions that challenge system requirements or safety functions.

• Provide engineering support for system operation, troubleshooting, maintenance, testing, and emergent equipment issues.
• Supply design-basis and technical input to maintenance work planning.
• Evaluate degraded and nonconforming conditions involving assigned systems, and support equipment-failure investigations, root-cause evaluations, and corrective actions.
• Establish or review technical acceptance criteria for maintenance and modification testing.
• Review completed work and test results to verify restoration of required system configuration and performance.

• Participate in change reviews affecting assigned systems.
• Evaluate changes for impacts to requirements, interfaces, performance, safety functions, documentation, testing, and equipment qualification.
• Support USQ screening/evaluations by providing accurate technical information.
• Support physical configuration walkdowns and reconcile discrepancies between field conditions and controlled documentation.
• Support Engineering Change Requests and Engineering Change Notices through implementation and closure.

• Monitor replacement-part availability and equipment obsolescence.
• Develop or review technical requirements for replacement equipment and components.
• Support equivalent-replacement and substitution evaluations.
• Review supplier and vendor technical information.

• Support design, installation, testing, and turnover of modifications to assigned systems.
• Participate in future Aalo-0 and Aalo-X reactor design reviews with emphasis on operability, maintainability, reliability, testability, and configuration control.
• Support commissioning and turnover of new systems.
• Assume responsibility for additional systems as…
