In this role, you will be our \"boots on the ground\" technical lead, supporting live field trials, military exercises, and pilot customer demonstrations. This position requires up to 25% travel, often to rugged, austere environments. When things go wrong in the field you must be a master of fast, high-impact field fix—troubleshooting the system, swapping modules, and using terminal commands to adjust parameters and keep the LightCell running. You will represent Mesodyne to military personnel and elite operators, requiring clear communication, sound judgment, and technical credibility. Key Responsibilities Field Demonstration Execution: Lead on-site deployment, fueling, startup, and testing of LightCell prototypes at military exercises, defense evaluation events, and trade shows. Rapid Field Troubleshooting: Act as the ultimate tactical troubleshooter. Diagnose electrical, mechanical, and firmware issues quickly under pressure and get systems back online. Communicate problems clearly to Engineering and collaborate on fixes. Technical Communication: Translate complex tech jargon from engineering into clear, direct, common-sense language for the customer. Build strong rapport with military end-users and gather crucial operational insights. Provide a daily debrief to HQ and a full trip debrief upon return. Matrix into Engineering: When you are not traveling or preparing for travel, you will be embedded with our Engineering Team, helping to assemble new units, build test fixtures, and document hardware performance in the lab. Qualifications & Skills Education: B.S. in Mechanical, Electrical, Mechatronics, Systems Engineering, or a related technical discipline. Hands-On Troubleshooting: A proven ability to build and debug physical prototypes is required (strong extracurricular projects and student project teams count!). Practical skills working with intricate mechanical assemblies are essential. Broad Engineering Skills: Solid mechanical hand-tools proficiency, comfort with basic electrical wiring/multimeters, and experience using command-line tools for debugging. Endurance, Grit, and Outdoor Character: You genuinely love traveling, the outdoors, and are comfortable operating in muddy, hot, or freezing austere training environments. We are looking for exceptional operational endurance and a relentless work ethic—someone who takes pride in working out tough problems and genuinely thrives under demanding conditions.

Think of the LightCell as a miniature, real-time chemical process plant packed into a portable footprint. This role is not about calculating aerospace flight paths or coding PLC factory automation line logic. Instead, you will design, implement, and tune multiple interacting, nested feedback loops—simultaneously throttling microfluidic fuel delivery, managing air-to-fuel ratios, and maintaining precise thermal boundaries—all written directly in C/C++ firmware for an STM32 running FreeRTOS. Key Responsibilities Control System Architecture: Design and optimize control strategies (PID, nested loops, feedforward, state-space, and MIMO, etc.) to manage the interconnected thermal, fluidic, and electrical domains of the LightCell. Bare-Metal Firmware Implementation: Translate control theory math directly into robust, real-time code. Implement, debug, and validate these algorithms directly in C/C++ on our STM32 microcontroller firmware. (No PLCs or ladder logic—you own the firmware level of the control system). Practical System Modeling: Develop mathematical models of physical components (heaters, pumps, valves, and combustion dynamics) using MATLAB/Simulink or Python to execute hardware-in-the-loop (HIL) simulations and predict transient responses. Use modeling to accelerate deployment, ensuring it serves as a bridge to real code rather than a final product. Hands-On Lab Tuning & Validation: Spend substantial time in the lab. Set up step-response testing, capture sensor data, and tune control coefficients on live physical prototypes to conquer highly non-linear thermal and fluidic dynamics. Qualifications & Skills Education: B.S., M.S., or Ph.D. in Mechanical, Electrical, Chemical, Systems, or Robotics Engineering. (We value a strong background in process control, thermal systems, or mechatronics). Control Loop Mastery: Deep practical and mathematical understanding of classical controls (Transfer Functions, PID, nested loops, feedforward, and stability margins). Experience managing slow, non-linear, interacting physical processes (thermal, pneumatic, hydraulic, or chemical) is highly preferred. C/C++ Firmware Competency: Production-grade proficiency writing digital control code directly in C/C++ for resource-constrained microcontrollers. This is a firmware-heavy role; pure MATLAB modelers or industrial PLC programmers will not fit the technical scope. Practical Test Skills: Eager to validate algorithms on physical hardware, tuning loops on live test setups to manage non-linear dynamics.
