Résumé du poste

Harmattan AI seeks a Mechanical Engineer to own the mechanical design of next‑generation Ground Control Systems hardware from concept through mass production. You will work at the intersection of mechanical design, RF integration, and electronics packaging to deliver field‑ready, defense‑grade products.

Responsibilities include CAD modelling in SolidWorks, GD&T, DFM/DFA optimization with suppliers, and rigorous testing under extreme field conditions.

Qualifications

Engineering degree in Mechanical Engineering, Mechatronics, Aerospace Engineering, or equivalent.
At least one full product development cycle from concept to mass production.
Plastic injection moulding experience with full DFM process and quality control; familiarity with CNC and die‑casting.
Experience with sheet metal fabrication, heavy metallic structures and large‑scale thermoforming is highly desirable.
CAD proficiency in SolidWorks with complex surface modelling and GD&T.
Hands‑on prototyping experience (3D printing, CNC, etc.) and integration of embedded electronics into complex enclosures.

Responsabilités

End‑to‑End Design: Design and prototype drone controllers, antenna systems, and launcher enclosures from scratch—covering structural architecture, ergonomics, thermal management, and 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 with plastic injection moulding, thermoforming, sheet metal/structural steel fabrication, CNC, and die‑casting suppliers.
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 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.
