About the Job

Requirements

A B.Sc. in Mechanical Engineering is required.
At least 10 years of experience in mechanical design and development is required; multidisciplinary-environment experience is preferred, and defense-industry experience is a significant advantage.
Proven experience providing technical leadership for complex product and systems development from concept through characterization, serial production, and New Product Introduction is required.
Proven experience with advanced engineering design to withstand static, dynamic, and thermal loads is required.
Deep familiarity with thermal materials, including thermal pads, thermal grease or paste, thermally conductive adhesives, heat pipes, and vapor chambers, is required.
Deep familiarity with military standards (MIL-STD) and sealing standards such as IP66/67, including knowledge and experience in vibration and thermal testing, is required.
Experience in electronic packaging, including design for printed circuit boards, is required.
Broad knowledge of production technologies such as CNC machining, casting, and injection molding, and proven ability to implement Design for Manufacturing and Assembly processes, is required.
Experience working technically with subcontractors in Israel and abroad, including defining engineering requirements, writing Statements of Work, and supervising execution, is required.
Proven experience preparing, leading, and presenting design reviews such as PDR and CDR, internally and externally to customers, is required.
High-level proficiency in computer-aided design software, especially SolidWorks, and experience working with Product Lifecycle Management systems are required.
Ability to work independently, maintain a broad system-level vision, and provide engineering solutions to complex challenges is required.

Responsibilities

Own all mechanical aspects of the product and work closely with hardware, production, operations, and product teams.
Provide technical leadership for complex mechanical designs.
Design products from scratch, retrofit existing designs, and improve existing designs.
Develop complex thermal-management solutions.
Design products to withstand dynamic profiles, primarily vehicle-related loads and wind loads.
Design protection against electromagnetic interference and electromagnetic compatibility issues.
Design products for sealing.

Desired Qualifications

Knowledge and experience using analysis software such as SolidWorks Simulation to perform dynamic, static, and thermal or heat-dissipation analyses.
Specific experience developing radar, radio, communication, or Command and Control (C4I) systems.

Protection against electromagnetic interference (EMI/EMC).
Design for sealing.

Requirements:

B.Sc. in Mechanical Engineering.

At least 10 years of experience in mechanical design and development, preferably in a multidisciplinary environment (significant advantage for experience in the defense industry).

Proven experience in the technical leadership of complex products and systems development from the concept phase, through characterization, to serial production and New Product Introduction (NPI).

Proven experience in advanced engineering design to withstand static, dynamic, and thermal loads.

Deep familiarity with thermal materials, including the use of thermal pads, thermal grease/paste, thermally conductive adhesives, heat pipes, vapor chambers, and more - MUST

Deep familiarity with military standards (MIL-STD) and sealing standards (e.g., IP66/67), including knowledge and experience in vibration and thermal testing - MUST

Experience in electronic packaging, including design for printed circuit boards (PCB).

Broad knowledge of production technologies (CNC machining, casting, injection molding, etc.) and proven ability to implement DFM/DFA processes.

Experience in technical work with subcontractors in Israel and abroad, including defining engineering requirements, writing SOWs, and supervising execution.

Proven experience in preparing, leading, and presenting design reviews (e.g., PDR, CDR) internally and externally to customers.

High-level proficiency in CAD software (with an emphasis on SolidWorks) and experience working with Product Lifecycle Management (PLM) systems.

Ability to work independently, broad system-level vision, and the ability to provide engineering solutions to complex challenges.

Advantages:

Knowledge and experience in analysis software (such as SolidWorks Simulation) for performing dynamic, static, and thermal/heat dissipation analyses.

Specific experience in developing radar, radio, communication, or C4I (Command & Control) systems.

About the Company

D-Fend Solutions

Autonomous counter-drone systems for urban environments

D-Fend Solutions delivers counter-drone technology that detects, locates, and neutralizes unauthorized drones in urban areas. Its core offering is an autonomous end-to-end system that intercepts a rogue drone’s control and data links, causing it to return to its takeoff point or land safely in a designated zone, while coexisting with existing wireless communications and GPS signals to avoid disrupting infrastructure. The system can also extract forensic data from the drone in flight to support real-time decisions and offline investigations. The company differentiates itself through its emphasis on non-disruptive operation in dense environments, seamless integration with current networks, and an end-to-end capability that includes ongoing maintenance and support. Its goal is to provide a safe, effective, and reliable solution to combat unauthorized drone activity by governments, critical infrastructure operators, and enterprises alike.
