Mechanical Engineer

Job Description Must Have Technical/Functional Skills Job Duties: Mechanical Engineer Hardware & System Design Skills Environmental Control Systems (ECS): Designing aircraft air cycle, vapor cycle, bleed air, or cabin pressure architectures. Component Sizing & Selection: Calculating specifications for valves, regulators, heat exchangers, actuators, compressors, and fans. Fluid & Gas Dynamics: Modeling pneumatic flow rates, routing ducting networks, and analyzing system pressure drops. Electro-Mechanical Integration: Interfacing mechanical hardware with basic electrical circuits, wiring harnesses, and feedback sensors. Analysis & Simulation Skills Thermodynamics & Heat Transfer: Performing manual thermal math or complex 3D heat-load calculations. Control Theory & Logic: Developing feedback control loops to actively regulate temperature, pressure, or airflow. Thermal Analysis Software: Utilizing specialized simulation tools like Thermal Desktop, Ansys Fluent, Flowmaster, or Simscape. CAD Modeling & Drafting: Generating production-ready 3D models and technical drawings using NX, CATIA, or SolidWorks. Testing & Compliance Skills Hardware Troubleshooting: Resolving mechanical failures during the physical assembly, functional testing, or component repair phases. Aerospace & Defense Standards: Aligning qualification test procedures with rigorous compliance benchmarks like MIL-STD-810 and DO-160. Test Plan Execution: Drafting test documentation, building test setups, and analyzing environmental test data. Core Skill Set to Look For ECS Subsystem Integration: Hands-on experience with aircraft or spacecraft bleed air, cabin pressurization, oxygen generation, or severe-environment ducting and layout. Thermal System Design & Analysis: Experience sizing heat exchangers, vapor cycle systems, cooling loops, or air cycle machines using software like Thermal Desktop, ANSYS Fluent, Flow master, or MATLAB/Simulink. Component Selection & Validation: Proven track record calculating fluid flow, pressure drop, and thermal loads to select or design valves, regulators, fans, or compressors. Industry Standards & Testing: Direct familiarity with aerospace/defense testing compliance, specifically DO-160, MIL-STD-810, or ARP862 for environmental control equipment. Cross-Functional & Control Logic: A strong understanding of structural interfaces, sensor integration, and basic control theory (e.g., feedback loops) to regulate temperatures and pressures. Technical Presentation & Leadership: Experience acting as a secondary project owner, leading small groups of drafters/designers, and presenting design reviews (PDR/CDR) to internal teams or customers. EDUCATION AND EXPERIENCE: Bachelor's degree (B.S.M.E) from four-year College or University. Two to five years of experience with design, analysis and development of industrial equipment. Aerospace domain experience is a must. Knowledge of applied thermodynamics and mechanical design. Knowledge of drawing and drafting standards a plus. Capable of carrying out assignments concerned with mechanical equipment. Understanding of military specifications, environmental specifications, and test specifications desired. Hands-on test and hardware experience is required. Requires strong oral/written communication skills and must be capable of conducting effective oral presentations to customers.
