Key Responsibilities:

• Lead an international engineering team on Nuclear Island structures for EPR nuclear power plants.
• Design and analyze reinforced concrete and steel structures
• Ensure compliance with Eurocode, ETC-C, and nuclear safety standards.

• Collaborate with BIM teams, drafters, and engineers to ensure design coordination.
• Evaluate and implement design changes, maintaining compliance and performance.
• Deliver technical documentation, drawings, and structural specifications.
• Provide on-site support during construction, resolving structural issues.
• Mentor junior engineers and oversee detailing work.
• Liaise with clients, regulators, and construction teams to ensure CDM and safety compliance.
• Maintain up-to-date knowledge of industry standards, tools, and best practices.

Required Skills:

• Proven experience in RC and steel structure design for large scale infrastructure projects.
• Solid understanding of Eurocodes
• Proficiency in structural analysis tools like STAAD Pro
• Strong capability in seismic design and complex load assessments.
• Experience supporting construction sites, resolving structural challenges in real time.
• Familiarity with 3D BIM tools like TEKLA and Navisworks is a plus.

Required Qualifications:

• A Bachelor’s or Master’s degree in Engineering, or equivalent military experience.

Personal Attributes:

• Proactive, autonomous, and solution-oriented.
• Excellent teamwork and communication skills in multidisciplinary environments.
• Committed to safety, quality, and regulatory compliance.
• Able to manage multiple priorities with attention to detail and delivery.
