Position Overview

As a Mechanical Design Engineer, your job is to design, build, test, and ship mechanical systems that survive real-world use .

From early prototypes to scaled production, you own your parts end-to-end. If it breaks, you fix it. If it doesn't exist yet, you design it. If it works on paper but fails in the field, it's not done.

Extreme ownership is the baseline. You will be expected to work late hours and weekends if needed to accomplish the mission.

Your work directly arms the warfighter. That responsibility is non-negotiable. Real ownership, not task lists, Hardware that goes from bench to field fast, A team that values execution over ego, A mission that actually matters. 

What You Own

• The mechanical integrity, performance, and manufacturability of your designs
• Components, mechanisms, and structures from concept → production
• Iteration speed without sacrificing reliability or safety
• Getting parts built, assembled, tested, and validated-no handoffs
• If it touches metal, motion, load paths or force, you're accountable

What You Actually Do

Component & System Design

• Design components with full lifecycle responsibility: calculations, tolerances, GD&T, drawings, and validation
• Design in context -your parts must work with everyone else's, under real loads

Mechanisms

• Design and integrate linkages, gears, motors, actuators, and assemblies that work under stress

Prototyping & Fabrication

• Build fast using in-house tools or external vendors
• Own the loop from CAD → part → install → revision

Testing & Validation

• Test like it's going to the field-because it is
• Measure performance, identify failure modes, and fix them
• Paper success doesn't count. Field performance does

DFM & Scale

• Design for manufacturability from day one
• Work directly with manufacturing and machinists to ensure precision, repeatability, and scale

Procurement & Build Support

• Source materials, components, and vendors to keep builds moving
• Solve supply problems without waiting for permission

Ownership & Adaptability

• Priorities shift. Problems emerge. You step in
• No "that's not my job." Only "what needs to be done."

Documentation & Improvement

• Document designs, tests, processes, and lessons learned so hardware can be built again
• Raise the bar on safety, reliability, and speed every cycle

Required Skills and Experience

• Proven, hands-on mechanical design experience
• Strong CAD and GD&T capability
• Ability to work independently in high-stakes, fast-moving environments
• Bias for action, high accountability, and resilience under pressure

Preferred Skills and Experience

• Weapons systems, UAVs, aerospace, or high-performance mechanisms
• Designing hardware that survives testing not just reviews it
• Additive manufacturing and 3D printer operation/maintenance
• Designing for production-not just prototypes
• Startup or small-team environments where impact is immediate
• Onshape experience a plus; willingness to transition required

Work Location:

This role is assigned onsite at our Leander, TX facility.
