Mechanical Design Analysis Engineer Jobs in Texas

Location: Dallas, Texas

Compensation: $140,000 - 210,000 USD / year

Shield AI is a venture‑backed defense‑tech company focused on protecting service members and civilians with intelligent systems.

We are looking for a Staff Mechanical Design & Analysis Engineer to join the V‑BAT propulsion engineering team. This role requires ownership of mechanical design from concept through production release, alongside performing the mechanical analysis needed to prove design efficacy.

You will design propulsion system components and subsystems, analyze them for strength, stiffness, fatigue, vibration, thermal behavior, manufacturability, and reliability, and drive those designs through prototyping, test, release, and production cut‑in.

This is not a pure analysis role nor a pure CAD role. The right candidate is a hands‑on mechanical engineer who can create excellent hardware, justify design decisions with sound engineering analysis, and own the details required to deliver flight‑critical propulsion hardware into production.

What you’ll do:

• Design propulsion system components and subsystems for V‑BAT, including:
  • Fuel and oil delivery hardware
  • Two‑stroke engine components and supporting hardware
  • Engine thermal‑control components
  • Propeller and duct‑ed‑fan‑adjacent mechanical hardware
  • Mounts, brackets, housings, retention features, tubing supports, and related propulsion hardware
• Perform mechanical analysis to guide and validate your designs, including:
  • Static strength and stiffness analysis
  • Hand calculations and fundamental sizing
  • Finite element analysis where appropriate
  • Fatigue and durability assessment
  • Vibration and modal analysis
  • Bolted‑joint, bearing, shaft, bracket, and mount analysis
  • Thermal growth, clearance, and tolerance‑stack analysis
  • Basic thermal/structural coupling where needed
• Own mechanical design trades between mass, stiffness, strength, cost, manufacturability, serviceability, and reliability.
• Create and maintain high‑quality CAD models and drawing packages for propulsion components and assemblies.
• Route and retain wire harnesses, fuel lines, oil lines, cooling lines, and other propulsion‑adjacent tubing or fluid systems.
• Own engineering change orders (ECOs) for your components from problem definition through release.
• Support configuration management for the propulsion system, including accurate documentation of released hardware, prototype configurations, and production cut‑ins.
• Coordinate design releases with manufacturing, quality, supply chain, flight test, program management, and other engineering teams.
• Own and execute verification and validation test campaigns for your hardware.
• Analyze test data from ground and flight testing to determine whether components meet structural, thermal, vibration, durability, and reliability requirements.
• Work closely with electrical, mechanical, aero‑performance, software, manufacturing, and flight‑test engineers to ensure your designs integrate cleanly into the full aircraft.
• Investigate failures, nonconformances, production escapes, and field issues, and drive corrective actions through design updates, process changes, or test improvements.

• B.S. degree in Mechanical Engineering or Aerospace Engineering.
• 5+ years of professional mechanical design experience.
• Strong proficiency with 3D CAD modeling and detailed mechanical design.
• Experience developing production‑ready engineering drawings and documentation.
• Understanding of GD&T (Geometric Dimensioning and Tolerancing) and manufacturing processes.
• Experience owning components through the full product lifecycle from concept through production.
• Experience supporting prototype builds, testing, and design iteration.
• Strong cross‑functional communication and project coordination skills.
• Ability to work effectively in a fast‑paced hardware development environment.

• Experience in aerospace, aviation, defense, motorsports, or other high‑performance mechanical systems.
• Proficiency with Siemens NX.
• Experience designing engine, propulsion, fuel, lubrication, thermal management, or rotating machinery systems.
• Experience with wire harness routing, tubing design, and aircraft integration.
• Familiarity with configuration management and engineering change processes.
• Experience supporting flight test programs or airborne hardware development.
• Knowledge of composites, sheet metal, machined components, castings, and additive manufacturing.
• Experience with environmental, durability, vibration, and qualification testing.
• Familiarity with FAA, military, or aerospace development practices.
