Engineer II, Hydraulics (R4936)

Mechanical Engineer responsible for designing and developing complex hydraulic fluid systems for autonomous aircraft UAVs. Requires 2+ years of experience in mechanical design with a focus on fluid systems, strong CAD skills, and expertise in structural analysis and FEA.

About the job

Responsibilities

  • Design complex hydraulic fluid systems for autonomous aircraft launch and recovery systems
  • Support the full design process: concept, CAD, tolerance analysis, material selection, and drawing release
  • Perform structural calculations and preliminary FEA
  • Prototype, test, and iterate mechanism designs for functionality and reliability
  • Collaborate with electrical, avionics, flight controls, manufacturing, and test teams
  • Support pre-production builds, prototype integration, and ground/flight testing
  • Participate in design reviews, architecture discussions, and technical decision-making forums related to hydraulic systems
  • Identify opportunities to improve design processes, configuration management, and team workflows for increased engineering velocity and design quality

Requirements

  • B.S. in Mechanical/Aerospace Engineering
  • 2+ years in mechanical or mechanism design with a focus on fluid systems
  • Strong CAD skills (NX preferred)
  • Kinematic analysis and optimization
  • Structural analysis utilizing hand calculations and finite element methods
  • FEA analysis: Modal, non-linear and linear, buckling, fatigue
  • GD&T and tolerance stack-ups for mechanical systems
  • Materials selection inclusive of alloys, heat treatments, allowables, and finishes
  • Ability to work independently in fast-paced, cross-functional teams

Nice-to-Haves

  • Experience with UAVs, aircraft, or robotic systems
  • Familiarity with electro-mechanical actuators
  • Proficiency in FMEA, DOE, and root cause analysis
  • Hands-on machine shop or mechanic experience (professional or hobby)
  • MIL-STD-810, structural, or actuated mechanism testing experience
  • Ability to thrive in startup, R&D, or defense innovation environments
