About Aalo Atomics

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.

About the role

We are seeking a Nuclear Safety Integration Lead to coordinate and integrate the technical inputs needed to develop and defend Aalo's DOE safety basis and Preliminary Documented Safety Analysis (PDSA). Reporting to the Nuclear Safety Manager, this role serves as a critical integration point among the DOE authorization team, the Risk and Reliability group, thermal-hydraulics, neutronics, design, and other contributing engineering teams. You will ensure that safety requirements are understood, responsibilities are clear, and the resulting analyses support a consistent and defensible safety case.

This is a high-visibility coordination role that requires deep familiarity with DOE safety basis requirements, strong technical judgment across multiple engineering disciplines, and the ability to drive alignment among diverse technical teams on complex analytical products. You will work closely with the DOE authorization lead and responsible technical teams to translate regulatory requirements into actionable engineering work, identify integration issues early, and ensure that the PDSA and related safety documentation are technically sound and defensible.

What you'll do

• Develop and maintain an integrated PDSA content, requirements, and responsibility plan that defines scope, ownership, interfaces, and delivery milestones for all contributing technical teams.
• Coordinate the preparation, integration, internal review, and technical defense of the PDSA and related DOE safety documentation, working with the DOE authorization lead and responsible technical teams.
• Translate applicable DOE safety-basis requirements and standards into specific analysis, report, and data needs for contributing engineering teams, including clear interfaces and dependencies.
• Identify analytical methods, codes, and key assumptions requiring DOE alignment, and coordinate early and ongoing engagement with DOE through the DOE authorization lead to confirm their suitability for intended safety-basis applications.
• Coordinate the integration of inputs from Risk and Reliability, including PRA, deterministic safety analysis, dose consequences, thermal-hydraulics, neutronics, fuel performance, hazards analysis, and supporting engineering information into the DOE safety case.
• Identify gaps, inconsistent assumptions, missing interfaces, and unresolved technical questions that could affect the PDSA, DOE authorization, design, resources, or schedule, and communicate them to the appropriate decision-makers.
• Establish a structured process for providing safety and risk feedback to design teams and tracking the resolution of safety-related design questions.
• Define how safety inputs are communicated to design teams, document the basis for their disposition, maintain traceability to affected analyses and requirements, and confirm closure with responsible teams.
• Facilitate technical integration meetings and working sessions to resolve cross-discipline analytical interfaces, assumptions, and dependencies.
• Track and manage the status of PDSA deliverables, technical inputs, and open items across contributing teams, escalating schedule or quality risks as appropriate.
• Support the development of responses to DOE requests for additional information, safety evaluation reports, and other regulatory interactions related to the safety basis.
• Coordinate with the nuclear safety team to ensure consistency between PDSA content and other safety basis documents, including hazard analyses, TSRs, and USQ evaluations.
• Maintain configuration management of integrated PDSA content, ensuring version control and traceability of technical inputs and assumptions across contributing disciplines.
• Support preparation for DOE readiness assessments and authorization milestones by ensuring the completeness and defensibility of the integrated safety case.

Qualifications

• Bachelor's degree in Nuclear Engineering, Mechanical Engineering, Chemical Engineering, Physics, or a closely related technical discipline.
• 8+ years of experience in nuclear safety analysis, safety basis development, or technical integration at DOE nuclear facilities.
• Demonstrated experience coordinating multi-discipline technical inputs into DOE safety basis documents such as DSAs, PDSAs, or equivalent.
• Strong working knowledge of DOE safety-basis requirements, including 10 CFR 830 and DOE-STD-3009.
• Experience translating regulatory requirements into specific engineering analysis and documentation needs.
• Familiarity with probabilistic risk assessment, deterministic safety analysis, and dose consequence methodologies as applied to nuclear facility safety cases.
• Experience coordinating with DOE on analytical methods, codes, and assumptions for safety-basis applications.
• Strong technical writing and communication skills, with the ability to present complex, multi-discipline safety arguments clearly and concisely.
• Proven ability to manage multiple concurrent technical deliverables and drive cross-functional teams toward integrated outcomes.
• Effective interpersonal skills with the ability to build productive working relationships across engineering, operations, and regulatory teams.

Preferred Qualifications

• Advanced degree (M.S. or Ph.D.) in a relevant engineering or scientific discipline.
• Experience with thermal-hydraulic, neutronic, or fuel performance analysis codes used in DOE safety basis applications.
• Direct experience preparing or defending a PDSA or DSA for a new or modified DOE nuclear facility.
• Familiarity with hazard analysis methodologies, including process hazard analyses and bounding accident analyses for nuclear facilities.
• Experience supporting DOE readiness assessments, Operational Readiness Reviews, or Federal Readiness Assessments.
• Background in advanced reactor technologies, microreactors, or first-of-a-kind nuclear facility design and authorization.
• Experience managing configuration control of complex technical documents with inputs from multiple organizations.
• Familiarity with Integrated Safety Management System principles and their application to safety basis development.
• Experience interacting with external oversight bodies such as the Defense Nuclear Facilities Safety Board.
• Project management or technical program management experience in a nuclear or defense environment.

Work Environment

• Combination of office and field environment at the Aalo-X campus.
• Periodic visits to operating nuclear facility areas with appropriate PPE and access controls.
• Occasional travel to DOE headquarters, other Aalo locations, or industry events as required.

What Success Looks Like

• A complete, well-integrated PDSA with clear ownership, traceable technical inputs, and no unresolved gaps in the safety argument.
• Engineering teams that understand their safety-basis deliverables, interfaces, and timelines without ambiguity.
• Early identification and resolution of cross-discipline technical issues, preventing late-stage surprises in the DOE authorization process.
• Strong alignment between Aalo and DOE on analytical methods, codes, and key assumptions before significant analytical effort is invested.
• A structured, functioning process for communicating safety feedback to design teams with documented disposition and closure.
• DOE readiness assessments and authorization milestones met on schedule, supported by a defensible and internally consistent safety case.
