## 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.

As a Mechanical Engineer on Harmattan AI's Ground Control Systems (GCS) team, you will own the mechanical design of next-generation GCS hardware from concept through mass production. This may include a premium drone controller for ISR missions, a long-range antenna system for multiple drone vectors, or an interceptor drone launcher box. You will work at the intersection of mechanical design, RF integration, and electronics packaging to deliver field-ready, defense-grade products.

**Responsibilities**

- **End-to-End Design:** Design and prototype drone controllers, antenna systems, and launcher enclosures from scratch—covering structural architecture, ergonomics, thermal management, and high environmental/waterproofing (IP rating) constraints.

- **Product Development:** Own full product development cycles end-to-end, translating operator needs into rugged, field-ready designs.

- **CAD Modelling & GD&T:** 3D model in SolidWorks, including complex surface modelling, and produce detailed 2D drawings with GD&T to meet strict functional and assembly requirements.

- **DFM/DFA:** Apply DFM/DFA principles systematically to minimise unit cost and assembly time at scale, collaborating closely with suppliers specialising in plastic injection molding, large-scale thermoforming, sheet metal/structural steel fabrication, CNC, and die-casting.

- **Simulation:** Run FEA (stress, deformation) and thermal simulations (CFD/steady-state) to validate design choices early and reduce physical prototype cycles.

- **Testing & Validation:** Conduct mechanical stress, failure analysis, and environmental testing to validate designs for extreme field conditions.

- **Cross-Functional Collaboration:** Collaborate daily with the Electronics and RF teams on PCB integration, internal routing, and RF constraints.

- **Supply Chain Partnership:** Partner with Supply Chain & Procurement on supplier qualification, cost targets, and the smooth transition from prototyping to mass production.

- **Documentation:** Maintain detailed documentation of designs, test results, and production workflows to support knowledge sharing and continuous improvement.
 

**Candidate Requirements**

- **Education:** Engineering degree in Mechanical Engineering, Mechatronics, Aerospace Engineering, or equivalent.

- **Experience:** At least one full product development cycle taken from concept to mass production.

- **Manufacturing Expertise:** Plastic injection molding experience with full DFM process and quality control; familiarity with CNC and die-cast molding.

- Experience with **sheet metal fabrication, heavy metallic structures **and **large-scale thermoforming** is highly desirable.

- **CAD Proficiency:** Advanced proficiency in SolidWorks, including complex surface modelling and 2D drawings with GD&T.

- **Prototyping & Integration:** Hands-on rapid prototyping experience (3D printing, CNC, etc.) and a proven track record of integrating embedded electronics into complex enclosures.
**Nice to have:**

- Basic FEA (stress, deformation) and thermal simulation (steady-state, CFD) experience.

- Understanding of mechanical linkages and **actuator/cylinder kinematics** for deployment or launching mechanisms.

- Experience in defense, aerospace, UAVs, or high-end consumer electronics hardware.

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