Electrical Engineer for Intermediate Difficulty RF Design, Prototyping, and Testing

Seeking RF/embedded electronics engineer — 433MHz TX board, consumer fishing electronics Initial schematic and PCB layout for the transmitter board are complete in EasyEDA. We need an experienced engineer to review, correct, and finalize the TX board, interface with JLCPCB for prototype fabrication using customer-supplied components from LCSC (SMT), assemble and functionally test prototypes (THT), and deliver a written test report alongside production-ready design files. TX Board summary: WPT receive charging circuit (TP4056, B5819W bridge rectifier), EV1527 OOK encoder, F115 RF PA, LMC555 charge indicator, AO3401A PMOS burst gate, LIR2032 coin cell. ~6 ICs, ~15 passives. 2-layer EasyEDA design, JLCPCB fabrication, LCSC or similar component sourcing. Deliverables: Reviewed and corrected EasyEDA schematic and PCB layout JLCPCB prototype order placed using customer-supplied LCSC components Functional test report with pass/fail results and photos or video of working boards Production-ready Gerbers, BOM, and CPL files Requirements: Demonstrable RF PCB experience, preferably consumer electronics at 433MHz Comfortable working natively in EasyEDA Familiarity with JLCPCB and LCSC fabrication and sourcing workflow Basic bench equipment Budget: Fixed price, two milestones. Milestone 1: design review and corrections ($100–150). Milestone 2: fabrication, assembly, functional test, and final files ($150–200 plus approximately $100 hard cost reimbursement for boards and components). This is the first of three PCBs for a growing fishing electronics brand. Strong performers will be considered for the remaining two board designs.
