Hybrid Systems Engineer (Mech/Software) for Defense Tech

WGS Systems, LLC; Frederick (MD); Hybrid; USD 70,000 - 120,000; Full time

Job summary

WGS Systems, LLC in Frederick, MD seeks an early-career multidisciplinary engineer for a hybrid role across mechanical design and software integration. You will split time roughly 50/50 between CAD design, structure/thermal analysis, prototyping, and embedded software development for sensor systems.

The position offers exposure to data pipelines, analytics interfaces, and FAT demonstrations, with collaboration across electrical, data science, and systems engineering teams. U.S.

Qualifications

• Bachelor’s degree in Mechanical Engineering, Mechatronics, Robotics, Aerospace Engineering, or related field.
• 2-5 years of professional experience in product development, preferably in defense, aerospace, or electronics.
• U.S. Citizen (required for contract work; ability to obtain USG security clearance).
• Proficiency in CAD software (SolidWorks, CREO, or similar) with experience designing mechanical assemblies for electronics products.
• Working knowledge of FEA tools (ANSYS, COMSOL, or SolidWorks Simulation) for structural/thermal analysis.
• Strong programming skills in Python; familiarity with MATLAB, C/C++, or LabVIEW.
• Hands-on experience with prototyping, fabrication methods, and working with machine shops.
• Understanding of mechanical testing methods (vibration, shock, thermal cycling).
• Excellent problem-solving skills with ability to work independently on multiple projects.

Responsibilities

• Design mechanical assemblies, enclosures, and mounting solutions for sensor systems using CAD (SolidWorks/CREO preferred).
• Perform structural, thermal, and vibration analysis to meet environmental requirements (MIL-STD-810, DO-160).
• Support prototyping, fabrication coordination, and design for manufacturability with machine shops.
• Conduct mechanical testing and validation; document results for design verification.
• Create and maintain engineering drawings, BOMs, and documentation per AS9100.
• Collaborate on packaging for RF systems, thermal management, and integration with platforms.
• Develop test automation scripts and data acquisition software for hardware validation (Python, MATLAB).
• Write embedded software for sensor control, data logging, and system configuration (C/C++, Linux).
• Build data pipelines and ETL processes to ingest sensor data into analytics infrastructure.
• Develop preprocessing and feature extraction for ML model development.
