PITA Build Engineer

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

Kairos Power is seeking Build Engineers to develop, execute, and continuously improve the work packages used to integrate and build reactor systems. Build Engineers bridge planning, scheduling, and field execution: they establish Clear to Build (CTB) before technicians begin, spend substantial time alongside the team during execution, and then incorporate observed lessons into the next revision. This is an operational engineering role that Kairos requires independent of AI adoption;

in an AI-native organization, the engineer is additionally expected to use modern AI tools proficiently to retrieve knowledge, improve work instructions, capture lessons, and build lightweight solutions.

Responsibilities

• Develop safe, clear, correct, concise, and complete work instructions/travelers for reactor construction, integration, test, activation, rework, and related activities.
• Translate drawings, bills of material, specifications, engineering requirements, safety controls, quality inspection requirements, tolerances, acceptance criteria, tooling, and prerequisites into executable work packages.
• Establish Clear to Build (CTB) readiness by identifying missing people, parts, plans, process, tooling, approvals, engineering inputs, or other prerequisites before work begins.
• Work alongside technicians during field execution to observe work firsthand, answer questions, capture deviations and lessons, and understand actual labor and serial duration.
• Perform hands‑on activities such as tube bending, swaging, panel buildouts, electrical terminations, and more.
• Use approved AI‑assisted retrieval and review to identify missing requirements, outdated references, configuration conflicts, applicable lessons, and unclear steps.
• Capture field observations using structured text, voice, photographs, and other approved multimodal methods.
• Develop lightweight AI‑enabled tools or workflows within approved enterprise platforms and processes when they improve local execution.
• Maintain work‑package and configuration traceability and adhere to designated engineering authority, quality hold points, and controlled systems of record.
• Identify, troubleshoot, and propose solutions for build and construction non‑conformances and solve complex assembly problems that may arise during fabrication and assembly of modular skids.
• Conduct regular field walk‑downs during builds to assess work‑package execution, verify as‑built conditions, and document discrepancies.
• Track task deadlines and production schedules based on project milestones.
• Support project reviews, ensuring manufacturing requirements and design decisions are clearly communicated, documented, and aligned with production goals.
• Communicate production status and risks effectively to stakeholders, including project leads, engineering, operations, and quality teams, ensuring alignment and transparency.
• Support continuous improvement by identifying inefficiencies and implementing process enhancements.
• Prepare and support execution of assigned work packages in accordance with applicable safety, quality, and regulatory standards throughout the production lifecycle.
• Support change management processes by evaluating engineering changes and assessing their impact on production timelines and…
