## Description

### **About Us**

Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.

### **About the Role**

As a Mechanical Engineer on Harmattan AI’s Airframe team, you will design UAV platforms and subsystems in an autonomous, fast-paced environment. You will take ownership of projects from concept through to production, ensuring optimal performance, reliability, and manufacturability.

###

### **Responsibilities**

- Design and prototype UAV platforms and complex subsystems from scratch, ensuring the right balance between durability, efficiency, and performance.

- Take full ownership of system-level constraints, including thermal management, mass budget (weight), COGS (cost), and environmental sealing (IP ratings).

- Work closely with R&D teams (Electrical, Software, and Industrialisation) to ensure seamless mechanical integration of sensors, payloads, and electronics.

- Conduct rigorous testing, including stress and failure analysis. Identify risks proactively and develop the necessary tools (test benches, calculation sheets, or scripts) to validate designs for operation in extreme environments.

- Manage your own delivery packages and technical specifications with precision, consistently meeting or exceeding requirements under tight deadlines.

- Oversee the manufacturing process by collaborating directly with suppliers and external manufacturers, with a focus on plastic injection moulding and precision machining, to ensure quality and schedule targets are achieved.

- Maintain the “source of truth” through Confluence and professional 2D/3D documentation. Document all designs, test results, and production workflows to support knowledge sharing and continuous improvement.

### **Candidate Requirements**

- Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.

- Proven experience designing and prototyping mechanical systems, ideally within UAVs, robotics, or defence applications.

- Proficiency in CAD software (e.g., SolidWorks); experience with structural and thermal analysis tools (FEA) is a strong advantage.

- Strong understanding of manufacturing processes, including high-precision machining and plastic injection moulding.

- Excellent written and verbal communication skills, with the ability to clearly document complex technical concepts and lead cross-functional discussions.

- Full commitment to Harmattan AI’s mission, vision, and growth plans, with a willingness to go the extra mile in pursuit of operational excellence.

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
