Electronics Engineer for Ultra-Thin Consumer Product (PCB & Power Management)

I am looking for an experienced electronics engineer to help design the hardware layout for a premium, rechargeable smartphone case project. Project Scope: * Determine technical feasibility for fitting components inside tight mechanical tolerances. * Select the correct hardware: an ultra-thin Lithium-Polymer (Li-Po) battery, an LED driver, a standard female USB-C charging port circuit, and a tactile switch. * Create the initial circuit schematic diagram based on my architectural requirements. I already have a highly detailed industrial design concept sheet, structural architecture breakdown, and exploded views ready to share. However, a signed Non-Disclosure Agreement (NDA) is strictly required before I can disclose these visual assets or full project specifications. Note on Budget: This is a fixed-price project of $200 for Phase 1. The expected deliverables for this phase are the complete component selection (Bill of Materials) and the initial circuit schematic. Full PCB trace routing and layout can be negotiated as a separate, subsequent milestone. Please reply with examples of your past experience engineering small, battery-powered consumer electronics or ultra-thin hardware. If you are a good fit, I will send over the NDA document so we can share the concept assets and get started.
