Sr​/Mechanical Design Engineer

HEN Technologies is a deep-tech company building the world’s first end-to-end intelligent fire suppression ecosystem, powered by AI, IoT, and advanced fluid dynamics. The company’s mission is to modernize how the world prevents and responds to fires by replacing outdated, manual systems with connected, data-driven technology that is more water-efficient and intelligently coordinated across every layer of the fire ground. Backed by funding from Venture Capital investors, HEN Technologies is proving that the future of fire defense is intelligent, connected, and preventative.

Join us as we redefine one of the world’s most critical industries.

HEN is constantly innovating new products to revolutionize the firefighting industry, and we’re seeking a Sr./Staff Mechanical Design Engineer to add to our small but growing product development team. As HEN expands its product portfolio we’re looking to add an ME with a diverse skill set – spanning mechanical design, rapid prototyping, and familiarity with electro‑mechanical systems. You will concentrate on transforming concepts into detailed mechanical designs, prioritizing design for manufacturing and assembly.

Your work will span all phases of the design cycle, from defining requirements to prototyping, testing, and refining designs. You’ll leverage in‑house prototyping capabilities for rapid iterations and validate your designs through experimentation; then work directly with manufacturing to bring the product to market. A hands‑on learner and someone proficient in rapid design and prototyping will thrive in this role.

• Lead the design, prototype, and validation testing of new firefighting equipment (nozzles, shutoffs, enclosures, etc.)
• Responsible for electromechanical design of HEN products
• Collaborate with vendors to mass manufacture components
• Continuous improvement of current product portfolio
• Hands‑on collaboration with manufacturing to bring new products online
• Develop internal test protocols, equipment, and carry‑out proof‑of‑concept tests
• Support design and testing through documentation

• Degree in Mechanical Engineering or related field;
  Bachelor’s with 4+ years
• Experience designing components for implementation in high‑volume production
  
  Familiarity with embedded electrical systems desired
• Strong fundamentals in fluid dynamics and material science
• Strong understanding of rugged industrial grade design
• Solid fundamentals of Design for Reliability (Shock/Vibration/Thermal)
• Familiarity with range of manufacturing and prototyping techniques
• Ability to thrive in a fast‑paced startup environment
• Authorization to work in the US

• Experience with microcontroller‑based system design
• Familiarity with valves, pumps, pressure‑flow systems
