Talascend is currently seeking a Principal Engineer for a remote, contract opportunity with our client.

Overview

In this role, you will support the development of plant level requirements and strategies relevant to complex seismic design and licensing activities, perform technical review of work products, and facilitate the integration and implementation of strategies and work products across project disciplines.

Responsibilities

Provide continuous oversight of seismic design scope, covering building and structural systems, foundations, equipment supports, and integrated plant analyses such as soil–structure interaction (SSI), seismic fragility development, and PRA inputs.
Coordinate and direct complex multi-system analyses, including SSI studies, seismic model development, external hazard characterization, and building seismic qualification, ensuring consistency with plant-level methodologies and licensing strategy.
Perform and guide SSI analyses using in-house SASSI tools; establish repeatable frameworks, workflows, and benchmarks that improve analysis efficiency and traceability across multiple structures.
Develop, document, and implement seismic design bases and strategies, supporting both deterministic and probabilistic methods; apply risk-informed, performance-based methodologies (e.g., LMP, RIPB) to define design acceptance criteria for SSCs.
Author, review, and refine plant- and system-level requirements and specifications, integrating seismic and structural criteria into design deliverables and ensuring seamless alignment with plant-level engineering.
Interface across design disciplines (mechanical, I&C, nuclear safety, systems) to ensure seismic requirements, structural criteria, and performance expectations are clearly defined, properly allocated, and implemented across interfacing designs.
Ensure adherence to licensing and code requirements (ASCE, ACI, AISC, ASCE 4/7/43, NUREG guidance), verifying they are correctly integrated into CSA products and aligned with licensing strategy.
Support cost studies and trade-off evaluations as the CSA/seismic SME, ensuring technical rigor while balancing constructability, schedule, and economic considerations.
Surveil subcontractor performance, monitoring design deliverables, verifying compliance with technical requirements, and ensuring design processes and quality programs are properly implemented.
Lead and support design and integration reviews, chairing cross-functional resolution sessions for CSA/seismic challenges, and facilitating targeted technical forums (e.g., working groups, decision boards, digital/in-person reviews).
Integrate seismic and CSA design information into licensing products, including regulatory submittals under the Licensing Modernization Project (LMP), ensuring design-basis alignment with licensing commitments.
Report emerging technical risks to project and engineering management, providing timely recommendations for mitigation and escalation when needed.
Drive continuous improvement, applying nuclear industry best practices to seismic modeling, fragility methods, and structural qualification, while identifying opportunities for improved efficiency, quality, and integration.
