Senior Mechanical Engineer

What We Do

Anno.ai is a mission-focused defense technology startup dedicated to accelerating the safe and effective development of next-generation autonomous systems. We specialize in building and operating advanced test ranges for low Technology Readiness Level (TRL) single- or dual-use autonomous platforms, providing a critical bridge between early-stage innovation and real-world mission requirements.

Position Overview

As a Senior Mechanical Engineer at Anno.ai, you will design, develop, prototype, document, test, and support manufacturing of systems used in field-deployable autonomous, sensor, and mission-support platforms. You will create 3D models, mechanical drawings, schematics, fixtures, mounts, enclosures, and components that enable rugged, reliable operation in demanding field environments.

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related technical field
• 5+ years of professional experience designing mechanical systems, enclosures, mounts, fixtures, rugged hardware, sensor payloads, or field-deployable equipment
• Strong proficiency with 3D CAD tools such as SolidWorks, Autodesk Fusion, or similar software, including production-quality mechanical drawing practices
• Experience with tolerance stack-ups, GD&T, revision control, design reviews, and manufacturable documentation
• Experience designing serviceable components for field-deployable hardware
• Experience supporting additive manufacturing, rapid prototyping, prototype fabrication, and design iteration from early concepts through functional test articles
• Experience supporting manufacturing processes such as CNC machining, sheet metal fabrication, additive manufacturing, composites, injection molding, casting, or low-rate production builds
• Ability to read and interpret technical documentation, schematics, layout files, BOMs, technical orders, and mechanical drawings
• Ability to obtain and maintain U.S. Government security clearance (U.S. citizenship required)
• Ability to travel up to 20%

Preferred Qualifications

• Prior experience supporting UAS/cUAS systems, defense or aerospace industry
• Experience designing for extreme environments
• Experience with maritime, coastal, buoy-mounted, vehicle-mounted, or other outdoor systems exposed to moisture, salt air, pressure, wind, temperature variation, and long-duration field operation
• Experience with MIL-STD-style environmental hardening, ruggedization, shock/vibration design, ingress protection, corrosion control, or field qualification testing
• Experience with additive manufacturing
