Job Posting: Electrical Engineer/Freelancer for PCB Schematic and Layout Development **Project Overview** We are seeking a skilled electrical engineer or PCB designer to convert a detailed verbal circuit schematic, netlist, and bill of materials (BOM) into professional manufacturing-ready files. The design is for a 150x160mm 4-layer FR4 PCB featuring an integrated analog pulsing card for resonant load R&D. This all-analog system (no microcontrollers) includes dual channels for pulsing (1Hz-1MHz) and gating (1Hz-100kHz), golden ratio frequency scaling, modulation features (envelope, jitter, ramp, burst), auto-tracking PLL/dwell, auto-voltage ramping, opto-isolation, and monitoring via BNCs and LCD. The board incorporates power supplies (buck/linear/charge pump), input interfaces, scalers, sweep/gate logic, high-side drivers, and feedback circuits. Full details will be provided in a PDF engineering packet upon hiring. This is a freelance project ideal for someone with expertise in schematic capture, PCB layout, and design verification. The goal is to produce accurate, error-free files ready for prototyping and manufacturing, ensuring circuit integrity, signal routing, performance specs, and compliance with standards like IPC-2221. **Key Responsibilities** - Review the verbal schematic, netlist, and BOM to fully understand the design. - Generate a complete schematic diagram using software like KiCad, Altium, or Eagle. - Perform PCB layout, including layer assignments (analog signals on Layer 1, GND plane on Layer 2 with splits, logic on Layer 3, HV power on Layer 4), trace widths/clearances (e.g., 0.25mm signals, 3mm HV), vias, shielding, and thermal management. - Verify the design through electrical engineering software (e.g., SPICE simulations for signal integrity, stability, and EMI; DRC/ERC checks for routing and performance). - Ensure all specs are met: stability across 1-60kHz, max current <0.85A, EMI <2dB, protections (fuses, MOVs, snubbers), and hierarchical sheets for clarity. - Produce final files: Gerbers (with Protel filenames), STEP/DXF for enclosure, drill files, assembly drawings, and any CAD exports needed for manufacturing. - Iterate based on feedback to confirm 100% functionality and manufacturability. **Requirements** - Proven experience in electrical engineering, with a focus on analog circuit design, schematic capture, and PCB layout. - Proficiency in tools like KiCad (preferred), Altium, or similar for schematic/netlist import and Gerber generation. - Strong knowledge of simulation software (e.g., LTSpice or Multisim) for verifying circuit performance, routing integrity, and specs (e.g., trace clearances per IPC-2221, thermal vias, EMI reduction). - Familiarity with 4-layer PCB designs, high-voltage/low-current systems, and resonant/analog applications. - Ability to work from verbal descriptions and netlists to create accurate visuals and files. - Excellent attention to detail, problem-solving skills, and ability to meet deadlines. - Portfolio or examples of similar projects (e.g., custom PCBs from specs) required in your bid. **Compensation and Timeline** - Fixed payment: $150 upon successful completion and delivery of all files. - Timeline: 1 week preferred, but negotiable based on your availability. - Payment via platform escrow upon approval. **How to Apply** Submit your bid with: - A brief overview of your relevant experience and why you're a fit. - Examples of past PCB/schematic work. - Estimated timeline and any questions about the project. We're looking for qualified freelancers to bring this innovative design to life—apply now if you have the expertise!

I’m not just here to “draw schematics” and “route traces.” I’m here to take your all-analog pulsing R&D board and make it come alive exactly as you’ve envisioned—while ensuring every frequency sweep, every gated pulse, and every resonant load test performs flawlessly from the very first prototype. Why I’m a Perfect Fit Hands-on Analog Expertise – I’ve designed complex multi-layer analog boards with frequency ranges and modulation schemes very similar to yours, including golden ratio scaling and precision gating. From Concept to Gerber – I excel in translating verbal schematics + BOM + netlists into accurate, error-free manufacturing files with IPC-2221 compliance. Signal Integrity Obsessed – I treat every trace width, plane split, and thermal via like mission-critical engineering, because in analog systems, layout is performance. Delivery: ~7 days from receipt of the full packet, +-1 day I’m ready to engineer it without compromise.
