• Oversee and direct external contract engineers employed by the company to ensure tasks are completed to acceptable standards and within required timeframes.

• Design and optimize components for manufacturability, ensuring seamless transition from prototype to scalable production.

• Utilize CAD software to create detailed 3D models, assemblies, and technical drawings.

• Integrate and troubleshoot communication protocols such as Modbus for hardware systems and IoT devices.

• Prototype components using 3D printing technologies, iterating designs based on testing and feedback.

• Assist in project management tasks, including timeline tracking, resource allocation, and stakeholder communication to ensure on-time delivery.

• Conduct design reviews, failure analysis, and continuous improvement initiatives to enhance product quality and efficiency.

• Support testing and validation processes to meet industry standards and performance requirements.

Preferred Qualifications

• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Industrial Engineering, or a related field.

• 1-5 years of relevant experience (entry-level candidates with strong internships or academic projects will also be considered).

• Hands-on experience with design for production (DFP) principles, including material selection, tolerances, and assembly processes.

• Familiarity with Modbus protocol for industrial automation and device integration.

• Basic knowledge of Arduino IDE and embedded systems.

• Experience with 3D printing technologies (e.g., FDM, SLA) and rapid prototyping workflows.

• Strong problem-solving skills and ability to work independently or in a team setting.

• Excellent communication skills for documenting designs and presenting ideas.

• Experience in project management tools (e.g., Jira, Asana) and methodologies (e.g., Agile, Scrum).

• Knowledge of additional manufacturing processes, such as CNC machining or injection molding.

• Exposure to electronics integration, sensors, or embedded systems.

• Passion for control systems, flow measurement, and emerging industrial technologies.

What We Offer

• Competitive salary and benefits, including 401(k) matching and PTO.

• Opportunities for professional growth in a mission-driven company with global impact.
