Senior Waterfront/Liaison EngineerTMMG is seeking an experienced Senior Waterfront/Liaison Engineer to provide full-time, on-site engineering support to shipyard during the USS Beloit (LCS-29) Post Shakedown Availability (PSA) at BAE Systems Jacksonville Ship Repair in Jacksonville, Florida. The engineer will serve as TMMG's on-site technical representative and a primary waterfront engineering Point of Contact supporting shipyard personnel, shipyard trades, and sub-vendors during execution of shipboard work. The position requires an experienced, hands-on waterfront engineer capable of independently investigating shipboard technical and workmanship issues, developing practical technical recommendations, and assisting shipyard with the adjudication of Trial Cards and deficiencies encountered during the availability. The primary anticipated workload involves structural pipe-hanger deficiencies and Remove & Replace (R&R) corrective actions; however, the engineer must possess sufficient shipbuilding and marine engineering experience to evaluate workmanship and technical issues across multiple ship systems and disciplines. This is a waterfront execution position requiring an individual who can operate independently aboard ship, communicate effectively with engineering and production personnel, and rapidly identify practical solutions while recognizing that final engineering disposition, design approval, and Trial Card closure authority remain with shipyard and the appropriate Government/Design Authority. The Senior Waterfront/Liaison Engineer will: Serve as the full-time, on-site engineering Point of Contact supporting shipyard during the LCS-29 PSA.Provide direct waterfront engineering support to shipyard personnel, shipyard trades, and shipyard sub-vendors performing shipboard work.

Provide engineering support for the implementation and adjudication of NAVSEA 4E work items and associated shipboard corrective actions. Support the resolution of structural pipe-hanger deficiencies, including evaluation of conditions requiring Remove & Replace (R&R) corrective action. Evaluate general manufacturing and trade-workmanship deficiencies affecting mechanical, piping, structural, electrical, and other shipboard systems within the engineer's demonstrated areas of competence. Review applicable drawings, technical requirements, work specifications, NAVSEA Standard Items, MIL-spec requirements, previous LCS technical solutions, and other available technical information when investigating waterfront issues. Utilize applicable lessons learned and previously approved LCS-class technical solutions, where appropriate, to support efficient resolution of recurring shipboard conditions. Assist shipyard with investigation and technical adjudication of Trial Cards while clearly identifying issues requiring elevation to shipyard Engineering or the appropriate Government/Design Authority. Coordinate technical issues with shipyard waterfront management, engineering personnel, production personnel, subcontractors, and other stakeholders as required. Clearly communicate the technical basis, recommended corrective action, status, and remaining actions associated with assigned deficiencies. Maintain diligent and continuous communication with shipyard management regarding open technical issues, investigation status, recommended solutions, schedule concerns, and matters requiring management attention. Maintain sufficient working records and supporting information to provide traceability of technical recommendations and ongoing waterfront issues.

The current planning baseline assumes no on-site effort during the calendar weeks containing the Thanksgiving and Christmas holidays. The ideal candidate is an experienced Navy shipbuilding or ship-repair engineer who is equally comfortable aboard the ship, reviewing a drawing, talking with a pipefitter or shipyard supervisor, and explaining a technical recommendation to shipyard engineering and program management. This position requires more than a traditional design engineer. TMMG is seeking an experienced waterfront problem solver who understands how ships are built and repaired, can recognize deficient workmanship, can rapidly determine what technical information is required to resolve an issue, and knows when a condition can be resolved at the waterfront versus when it must be elevated to the formal Engineering/Design Authority.
