We are looking for a junior design engineer (possibly a student) / specialist in 3D CAD modeling to assist in the development and release of documentation for industrial equipment (pipe and profile production lines). The work will involve preparing production drawings under the guidance of a lead engineer. Key requirements: Software: Proficient in Autodesk Inventor (solid modeling, assemblies, sheet metal, creating 2D drawings). Language: Good level of English (Intermediate / B1-B2 or higher). You must be able to understand technical assignments and discuss project details directly with colleagues from the USA. Technical background: Basic understanding of mechanical engineering, metal processing processes (welding, machining, laser cutting) and drawing standards. Responsibilities: 3D modeling of parts and assemblies in Autodesk Inventor based on sketches or existing developments. Modification and adaptation of existing equipment components. Detailing and formatting specifications and production drawings (part drawings, assembly drawings). What we offer: Remote project or part-time work with a flexible schedule. Experience working on international industrial projects. Please attach examples of your work (3D models or drawings made in Inventor) to your response, and briefly describe your level of English. This is a great opportunity to start working on international projects, gain experience interacting with colleagues from the USA, and grow into a high-level engineer on real, complex tasks.

Hello! I need advice on selecting ready-made components for a small project. The task is to implement two functions: 1. Automatic raising and lowering of a wooden roof using an electric motor. ( plywood size 60x40cm) 2. Turning on and off internal LED lighting. It is important that I am specifically interested in selecting compatible ready-made components without soldering and developing electronics. I want to build a system from ready-made modules with connectors or terminal connections. I need help with the selection of: ● a suitable motor; ● a power supply; ● switches or limit switches; ● a controller (if necessary); ● buttons or other control elements; ● cables, connectors, and other necessary components. I would like to receive a list of specific parts that can be ordered, so that after purchase, it will only be necessary to connect them together and install them in the product. I would appreciate advice and assistance in selecting the optimal solution. I will send more details in a private message.

The type-C must match the hole on the step model : It should look impressive for the model + don't forget about the monitor output! Best on black textolite And to avoid the obvious impression that it is not working :) (for the average user) Show me the board in the case

Need a professional engineer to calculate and design a modular trailer platform with a load capacity of 60 tons for a ready-made chassis. There are factory drawings. Changes need to be made.

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.
