At a glance

We are looking for an Industrial Engineer to join our rapidly growing team in Quonset, RI, operating as a flexible resource for the site and holding a standing factory-macro remit on behalf of 3SI.
You will move across programs and bring data-driven IE rigor to production line and workstation design, capital equipment, site-level factory layouts, and material flow.
Working shoulder-to-shoulder with Engineering, Supply Chain, Quality, Business Operations, and the Factory Services team, you will help get complex undersea hardware built and shipped to spec.

Deliver core Industrial Engineering standards and capabilities to Quonset's production lines — capacity planning, labor standards, time studies, workstation and line layouts, and discrete event simulation (DES).
Deploy across production lines as a shared resource — partnering with each line's Manufacturing leads to scope the work, deliver it, and hand off cleanly.
Own site-level factory layout and material flow — plan and maintain the master floor layout and optimize how material moves between receiving, storage, lineside, and shared services as programs scale and new capabilities come online.
Specify, justify, and deploy capital equipment and tooling — define requirements, own the business case and capex justification, and support vendor selection, build, install, and qualification through to production readiness.
Lead cross-functional technical projects on behalf of 3SI — scope, schedule, and drive site infrastructure, equipment, and process-improvement initiatives from definition through execution.
Own operations health metrics and KPIs and build the tools and reports that communicate line and site health across the org.
Identify bottlenecks and constraints across layout, part shortages, staffing, and tooling, then drive resolution with Manufacturing, Supply Chain, Engineering, and Quality.

5+ years past experience in a rate manufacturing environment and production-type role where complex mechanical and/or electrical assemblies were built.
Experience using real operational data to make informed suggestions and decisions.
Experience and demonstrated skills with AutoCAD.
Proven line/facility design: value stream mapping, continuous/one-piece flow, and workstation design.
Experience with Lean Manufacturing principles/implementation.
Able to read technical documentation (drawings, vendor schematics, CAD) and understand hardware processes across electronics and mechanical structures.
Understanding of the means and methods of how material flows around a facility including but not limited to pull systems + triggers, Kanban and MIN MAX calculations.
Experience modeling operations using discrete event simulation.
Working knowledge of an MES and an ERP (Oracle or equivalent).
Eligible to obtain and maintain an active U.S. Secret security clearance.

Bachelor's or higher in Industrial, Mechanical, Aerospace, Manufacturing, Electrical, or Computer Engineering.
Hands-on design of tooling, fixtures, or GSE (ground support equipment) for heavy or large-format hardware.
Data analytics knowledge and experience including the use of SQL to create complex custom queries, mining and joining tables from production and supply chain databases (experience with Palantir Foundry a plus).
Experience creating and owning program, project or production schedules.
Experience with Simio and/or Siemen's Plant Simulation.
Experience in a marine, subsea, or other regulated/harsh-environment hardware program.
