The Boeing Defense, Space & Security (BDS) – Phantom Works organization in St. Louis, Missouri, is seeking an Experienced Low Observables (LO) Design and Integration Engineer to support design, analysis, and propulsion subsystem integration of low‑observable materials, treatments, and architectures. The ideal candidate will have hands‑on experience with LO materials and technologies, demonstrated experience integrating LO solutions with advanced propulsion systems, strong understanding of electromagnetic (EM) principles affecting radar cross section (RCS) and signature, and practical experience using computational electromagnetic (CEM) solvers to design, predict, and optimize low observable systems.

• Perform design, analysis, and integration activities for LO integration of the propulsion subsystem into an advanced next generation platform, including inlets, nozzle/exhaust, and airframe interfaces.
• Use CEM solvers to model and analyze RCS, scattering, and signature behavior; iterate designs to meet LO requirements.
• Apply electromagnetic theory to assess materials, shapes, and structural features that affect signature across relevant frequency bands.
• Define and execute test plans and validation activities (lab and range) to verify LO performance and support correlation between simulation and measurement.
• Collaborate with multidisciplinary teams (structures, propulsion, materials, flight test, systems engineering, producibility) to ensure integrated solutions meet performance, manufacturing, and maintainability needs.
• Prepare technical documentation, specifications, design packages, and presentations for internal and customer review.

• Bachelor of Science degree in Engineering (with a focus in Electrical, Mechanical or Aeronautical), Computer Science, Data Science, Mathematics, Physics, Chemistry or non‑US equivalent qualifications directly related to the work statement.
• 3+ years of hands‑on experience working with low observable materials and technologies.
• Experience with low observable integration of advanced propulsion systems (inlet/engine interfaces, exhaust/nozzle integration).
• Understanding of electromagnetic principles relevant to RCS and signature control.
• Experience using computational electromagnetic (CEM) solvers (SENTRI, XPATCH, CARLOS, HFSS, FEKO, or similar) to design, analyze, and optimize LO systems.

• Active Top Secret clearance.
• Master’s or PhD in a relevant field.
• Experience with full‑platform RCS prediction workflows and multi‑physics (electromagnetics + thermal/structural) trade studies.
• Experience correlating CEM predictions with laboratory and range measurement data.
• Experience with advanced propulsion concepts and associated LO challenges.
• Familiarity with materials processing, application methods, environmental durability, and repair/maintenance impacts of LO treatments.
• Experience with CAD tools and model preparation for electromagnetic simulation.
• Strong technical communication skills, including written reports and oral presentations.
• Ability to work collaboratively in cross‑functional teams and manage multiple tasks to meet program schedules.

Successful candidates for this job must satisfy the Company's Conflict of Interest (COI) assessment process.
