Job Description
Aventra Defense Systems is seeking a mid-level Mechanical Engineer to own the design and productization of subsystems within our Piranha high-altitude platform — from early prototype through a field-ready, producible design. This is a hands-on, individual-contributor role with clear subsystem ownership: you'll take a specific piece of the system and drive it from where it stands today toward a production-ready product. Just imagine seeing the hardware you designed flying in the stratosphere.
Key Responsibilities Subsystem Design- Turn product requirements documents into reality! Own the mechanical design of an assigned high-altitude subsystem, building on and leveling up existing prototypes.
- Conduct rigorous FEA (structural, thermal, and vibration) to ensure your designs survive the extreme temperatures and dynamic loads of high-altitude flight.
- Design for reliability, manufacturability (DFM), and cost at the subsystem level.
- Experience the joy of rapid iteration—design a part in CAD, 3D print it in our shop, and have a finished prototype in your hands days later to test.
- Run bench-level and field testing to validate performance across extreme environmental and altitude conditions utilizing thermal/vacuum chambers and strain gauges to make sure your design works.
- Design and implement tests across a variety of systems and environments.
- Peer review other engineers' work.
- Conduct trade studies to understand the state of the art and industry best practices.
Integration & Test- Integrate your subsystems with electrical, aero, and software teams.
- Assist with flight test instrumentation setup and post-test data collection.
- Help maintain test equipment, fixtures, and lab organization.
- Test your design in the field and watch it fly!
Productization and Manufacturing- Drive the transition from a working prototype to a rugged, field-ready, producible design.
- Perform detailed tolerance stack-up analysis and apply GD&T to ensure complex assemblies fit flawlessly every time they come off the line.
- Identify and resolve manufacturing, sourcing, and reliability bottlenecks before they reach production.
- Support production handoff and work closely with machinists and external vendors to get your hardware built.
Integration & Iteration- Coordinate seamlessly with electrical, software, and aero teams, packaging complex avionics and integrating actuation, control, and sensor feedback interfaces.
- Assist with flight test instrumentation setup, post-test data collection, and lab organization.
- Test your design in the field and watch it fly!
- Dive into post-flight test data to root-cause anomalies, then rapidly incorporate field feedback into iterative design improvements.
Documentation & Process- Maintain accurate models, drawings, BOMs, and design documentation
- Support design review processes and component sourcing research
- Analyze and learn from failures and document so the organization doesn't have to learn the same lesson twice.
QualificationsMinimum Qualifications- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field
- 3-6 years of industry experience in mechanical design, ideally including high-altitude, pneumatic/fluidic, or release/deployment mechanisms
- Proficiency in CAD tools such as SolidWorks or OnShape, with a demonstrable portfolio of designs you've taken from concept through hardware
- Hands-on prototyping and testing experience
- US Citizen with ability to obtain and maintain security clearance
Preferred Qualifications- Experience in aerospace, defense, or other high-reliability industries
- Exposure to embedded systems or sensor integration
- Startup or small-company experience
- Familiarity with relevant military standards
- Competitive salary commensurate with experience
- Generous health coverage for employee and family, premium fully covered
- 4% 401k match
- PTO and Sick Leave
Travel & Work EnvironmentTravel Requirements- Travel up to 25% to customer sites, and field test locations
- Ability to work in austere field conditions and military operational environments
- Flexibility to support urgent operational requirements and schedule changes
Work Environment- In-person role based in Herndon, VA
- Collaborative environment supporting critical national security missions
- Direct support to warfighter capabilities and mission success
