Electro-Mechanical Engineer

At HEN Technologies, we’re building Physical AI for the real world—intelligent systems that sense, understand, and act in high-stakes physical environments. Our first application is transforming fire response: combining advanced fluid dynamics, IoT-enabled hardware, real-world operational data, and AI-powered decision support to help firefighters suppress fires faster, use less water, reduce fatigue, and improve safety. By connecting the physical layer of emergency response with predictive intelligence, HEN is building the infrastructure for a safer, more adaptive future.

Role Overview

HEN Technologies is seeking a hands-on Senior Electro-Mechanical Engineer to own the detailed mechanical design and motor integration for our next generation of nozzle systems.

This engineer will be responsible for transforming product and system-level requirements into optimized, manufacturing-ready nozzle assemblies. The role will include mechanical CAD, motor and actuator selection, detailed component design, prototyping, testing, design iteration, and production documentation.

This is an ideal opportunity for an engineer who enjoys solving complex mechanical problems, building and testing physical products, and taking designs from concept through manufacturing.

What You’ll Do

Nozzle Design and Optimization

• Own the detailed mechanical design of new nozzle architectures and related assemblies.

• Develop and optimize components for performance, durability, manufacturability, weight, packaging, and cost.

• Translate product requirements and engineering concepts into complete mechanical designs.

• Evaluate design tradeoffs involving geometry, materials, tolerances, actuation, fluid flow, and system integration.

• Build and test prototypes to validate designs and identify opportunities for improvement.

• Support design reviews, failure analyses, and iterative product development.

Motor and Actuator Integration

• Identify, evaluate, and source motors, actuators, gearboxes, sensors, and related electro-mechanical components.

• Integrate motors and actuation systems into broader nozzle and hardware assemblies.

• Define motor requirements, including torque, speed, duty cycle, power, packaging, environmental performance, and expected service life.

• Design mechanical interfaces, mounting systems, enclosures, transmission components, and cable-routing solutions.

• Develop test plans to validate motor performance, reliability, thermal behavior, and system-level operation.
