Engineer with Experience in Multi-Layer PCB Design, Firmware, and 3D Modeling Needed

I'm looking for an experienced engineer (electronic engineering) to improve a current device. The deadline for this project is 6 weeks. This project requires experience in multi-layer PCB design, firmware, and 3D modeling. I have already designed the schematic for the PCB, but improvements and optimization must be done to make a smaller PCB. The firmware needed for the project has basic functionality only. No specific requirements beyond this. If you think you are the right person for this job, then please reach out! We are looking for a talented and motivated engineer with experience in electrical and product engineering. The ideal candidate should have experience working with headphones, earbuds, and biometric sensors. The project involves the improvement of a current PCB board, 3D Model, schematic, and firmware. Many aspects of the project have already been developed in a larger-scale circuit model, and we now need to create a smaller prototype device. Key Requirements: Experience in electrical and product engineering Experience with headphones, earbuds, and biometric sensors Experience with PCBs and intermediate coding Ability to work independently and collaboratively in a fast-paced environment Strong problem-solving skills and attention to detail Strong communication skills The engineer will be responsible for the following tasks: Building and testing the prototype device Improving a current multilayer PCB to be working, while being smaller and more affordable to assemble Connecting the device wirelessly to a mobile or computer device to transmit data Troubleshooting and problem-solving as needed The deadline for this project is six weeks from the date of hiring, so the engineer must be able to work efficiently and effectively to meet this deadline. NDAs must be signed. If you are an electronic engineer with experience in building/designing circuits and consumer devices, we would love to hear from you! Please send us your resume, portfolio, or a brief cover letter outlining your experience and why you would be a good fit for this project. We are excited to work with a talented and motivated engineer who can help us bring our project to life! Hired engineer will be paid hourly, as we require usage of the "Freelancer Desktop App." Unfortunately, no manual inputs of time will be accepted, as only monitored hours from the desktop tracking app will be paid for.
