• Modular design and modular fabrication experience is highly preferred

• Strong command of international engineering codes and standards and industrial construction practices

• Experience working with multiple contractors and geographically distributed teams

Work Environment & Logistics

• Primary location: St. Gabriel, LA (Greater Baton Rouge area)

• Combination of office‑based engineering work and active construction site presence

• Ability to work safely in field environments, including wearing PPE and navigating construction areas

• Preference for local or regional candidates ; candidates willing to relocate at their own expense will be considered

• Travel may be required based on project needs

What We Offer:

• Opportunity to play a key technical leadership role on a long‑duration, flagship capital project
