Position Description & Qualifications

If you seek a rewarding, high profile and challenging position supporting projects for the US Navy- Serco has a wonderful opportunity for you! This position will be on a dynamic team, supporting Team Submarine. Bring your expertise and collaborative skills to make an impact on our military defense and safety of our sailors. As the Principal Naval Architect, you will be on a dynamic team providing technical and programmatic support to the VIRGINIA Class Submarine Program Office (PMS450) and the U.S. Navy’s Team Submarine Program Offices at the Washington Navy Yard in Washington, DC! Bring your expertise and collaborative skills to make an impact on our military defense and safety of our sailors.

Must possess a U.S. Department of War (DoW) Secret security clearance.

Serco supports the US Navy as a prime for their Team Submarine SHAPM contract supporting the acquisition of submarines. PMS450 is the acquisition program office for the New Construction of Attack Submarines and for identifying, assembling, managing, directing, and coordinating the resources required for the R&D, design, construction, Test and Evaluation (T&E), Live Fire Test and Evaluation (LFT&E), and Fleet introduction of the U.S. Navy’s newest class of nuclear attack submarines. PMS450 is responsible for developing and deploying a more affordable, nuclear-powered attack submarine with multi-mission capability and enhanced capabilities for performance in littoral areas. VIRGINIA Class submarines support five of the six Navy core maritime capabilities: Deterrence, Maritime Security, Sea Control, Forward Presence, and Power Projection.

Serco-NA is seeking a motivated individual to provide programmatic support to one of our NAVSEA customers. Serco-NA has an opening for and immediately hiring a Principal Naval Architect supporting the NAVSEA 05P3 as the Naval Architecture - System Integration Team (SIT) Team in PMS450, the VIRGINIA Class Submarine program office. This is an opportunity to join our growing team to contribute and influence the Navy's future, premier attack submarine. A submarine naval architect is responsible for the design, construction, maintenance, and repair of submarines. They analyze floating structures and take various features into account for their designs, such as the form, structure, stability, resistance, access, and propulsion of hulls. Naval architects work closely with marine engineers, shipyards, and regulatory bodies to ensure that submarines are well-designed and operationally efficient. They are involved in the design of hull forms to ensure optimal buoyancy and performance, as well as conducting hydrodynamic and structural simulations. A role as a submarine naval architect will take you on a journey like no other. Playing your part in creating powerful naval vessels, you’ll work on some of the most advanced technology in the world. This role will support the management and execution of technical and design requirements for new and ongoing submarine shipbuilding programs. Candidates should possess strong engineering and acquisition fundamentals, as well as expertise with surface and undersea shipbuilding programs.

In this role, you will:

Be responsible for the design, development, and optimization of submarines. Duties include:

Design and develop submarines by creating the initial design and layout of submarines, considering factors like stability, strength, weight, and performance in marine conditions. This involves creating complex mathematical models and using computer-aided design (CAD) software.

Modify and upgrade existing submarines design also be responsible for modifying and upgrading submarines to improve their performance, safety, or to adapt them to new uses and missions.

Overseeing construction and maintenance: After the submarine is built, will continue to be involved in its maintenance and repair, conducting inspections and tests to ensure its continued safety and performance.

Naval architects work closely with PMS450 or other stakeholders to understand the use of the submarine. They are responsible for creating the initial design and layout of the submarine, considering factors like stability, strength, weight, and the vessel’s performance in various marine conditions.

Areas of responsibility included weights, hydrostatics, stability, equilibrium, tank capacities, mass moments of inertia calculation, review of reballast proposals, inclining experiment, trim dive reports, and other naval architecture related documents (Ship Specifications, Ship Systems Manuals (SSM), Operating Instructions (OI), Casualty Procedures (CP), Test Procedures (TP), and Maintenance Manuals (MM)). Participated in all design phases: feasibility, delivery, conversion, and overhaul.

Understand technical requirements, verify the design meets those requirements (if possible), and that the stakeholders agree an acceptable risk level has been reached that the design can be successfully built and delivered.

Review shipyard weight reports, hydrostatics, tank capacities, module weights, prediction of mount/deck loadings, evaluation of system descriptions/diagrams, stability (GM&BG) prediction of various loading conditions, attend weight audit meetings, fixed ballast distribution, tracking weight and margin trends, and review of inclining experiment, trim dive reports, and reballast proposals.

Review variable ballast requirements for Special Operations missions.

Review of TempAlt and ShipAlt impacts, understanding Undersea Dominance (UD) payload integration impacts, fielding unusual questions such as loading for arctic transit, required reserve buoyancy and projected navigational draft.

Support NAVSEA 05P3 as the Naval Architecture - System Integration Team (SIT) Team including interacting with two naval shipyards and Electric Boat regarding naval architecture (weight, stability, ballasting, equilibrium, tank capacities, and hydrostatics), review of Ship Systems Manuals (SSM), Operating Instructions (OI), Casualty Procedures (CP), Maintenance Manuals, and Test Procedures.

Make recommendations to approve reballast proposals, review inclining experiment and trim dive reports.

Perform Mass Moment of Inertia/Gyradius Study when required.

Support NAVSEA weight control efforts.

Utilized the ASSET/MONOLA ship synthesis design program extensively.

Provide expert responses to requests for technical assistance or adjudication received via letter, Engineering Reports (ERs), Work Deferral Requests (WDRs), Departures from Specification (DFS), and Liaison Action Requests (LAR).

Assist with the development and implementation of programmatic documentation including ship and systems specifications, performance specifications, interface control documentation, and design decision documentation.

Provide subject matter expertise with managing programmatic, technical, administrative and support activities required to develop and execute the VIRGINIA Block V functions.
