Mechanical Engineer

America is critically deficient in production of defensive munitions- we currently produce shipborne interceptors in the few hundreds per year while our adversaries are producing offensive threats in the tens of thousands per year. Furientis was started to help solve this problem- introducing a new class of cost-effective, high production rate, interceptor missiles. We're seeking motivated individuals who internalize this problem and are eager to apply their past experience in similar industries (aerospace, defense, automotive/racing, robotics) and out of the box thinking to solve this problem for the US and its allies.

About The Team

Vehicle Engineering owns the missile as a physical object from design through flight: structures, mechanical integration of the full subsystem stack, and the build.

About The Role

We are looking for a mechanical engineer who can be the Responsible Engineer for our interceptor's mechanical hardware and the ground systems around it. You will design, analyze, build, and qualify primary and secondary structures, the mechanisms that move on the vehicle, and the launcher and ground support equipment the program runs on. You will work alongside our Principal Mechanical Engineer.

This is a generalist role. We do not have the headcount yet to split airframe, mechanisms, GSE, and launcher across separate engineers, and we are not trying to. The right person reaches across all of it, makes the calls that need making, and pulls in deeper analysis or outside help where the problem warrants it.

Every design decision is also a unit-cost decision, and we expect you to design accordingly.

What You'll Do

• Be the Responsible Engineer for the mechanical design of the interceptor: primary and secondary structures, mating interfaces with propulsion, seekers, avionics, GNC, and recovery, and the mechanisms that move on the vehicle other than fin actuation, which lives with the Control Actuation Engineer
• Own the loads and load-path story for the airframe. Hand calculations first, FEA when the problem warrants it
• Take parts from CAD to prototype to qualified flight hardware. Specify, source, machine, fabricate, inspect, and assemble alongside the technician team
• Design and build the launcher and the ground equipment the program runs on: handling fixtures, transport cradles, environmental enclosures, and the systems that mate the vehicle to the rail
• Run vehicle integration, environmental test, and ground and flight test campaigns. Reduce data, close out anomalies, and feed the lessons back into the design
• Set the drawing, CAD, and PDM conventions the rest of engineering uses. As the team grows, these become the standards that keep us moving fast
• Make material, process, and fastener calls with cost, mass, and producibility in mind. Pick the simplest solution that meets the requirement
• Coordinate with aero on outer mold line implementation, with propulsion on case and nozzle integration, with avionics on tray and harness routing, with the seeker team on optical-package interfaces, and with the Control Actuation Engineer on fin actuator integration into the airframe: hinge supports, OML cutouts, and sealing
  
  
  

Skills We're Hiring For

• B.S. in Mechanical, Aerospace, or related engineering. M.S. welcome
• 6 years of hands-on mechanical design of flight hardware, with responsibility for at least one program from CAD through environmental qualification
• Strong structural intuition. Hand calculations and load-path reasoning before FEA
• Fluency with both metallic and composite hardware: design, fabrication routes, and what it takes to get either through qualification
• Modern CAD and PDM fluency. We use NX and Teamcenter, but the package is not the bar
• Comfort setting GD&T and drawing standards that other engineers will work to
• Hands-on builder posture. Comfortable on the shop floor, at a test stand, and at a vendor
• AI-native working style: daily use of agentic coding tools (Claude Code, Codex, OpenCode, or similar) for analysis scripting, data reduction, and tooling
• U.S. Person, eligible to obtain a U.S. SECRET security clearance
  
  
  

Bonus Points For

• Tactical missile, munition, or interceptor program experience
• Launcher, canister, or launch-tube design experience
• GSE and handling-equipment design at any scale
• Mentoring or technical leadership experience, or interest in growing into it as the vehicle team scales
• Hands-on safety record working with energetic and hazardous materials
• Test facility or fixture standup experience
• Out-of-domain background that gives you practical, first-principles intuition (automotive, motorsports, robotics, eVTOL, hobbyist high-power rocketry). We actively want people who can solve vehicle problems without dragging legacy-prime habits with them
  
  
  

Eligibility & Logistics Location: On-site at our Los Angeles, CA HQ; remote work is not available. Monthly weekend travel for test events and supplier engagements. Clearance: A clearance is not required for this position. Must be a U.S. Person.
