Electronics Hardware Designer Needed

@AlexandrGergel

KICAD Greetings, I have 10+ years in embedded systems, mainly STM32/ESP32 and low-level hardware/firmware work, and recently I have been doing schematic, PCB layout, component selection, and bring-up work for sensor and controller boards. I mainly use Altium for PCB work, but I can also review and work with KiCad designs, especially checking power, MCU connections, interfaces, component footprints, routing, and manufacturing issues before ordering boards. For this kind of work, I think the important part is not just checking the schematic but also checking datasheets, availability, layout details, and possible bring-up problems together. I can handle small review tasks the same day in most cases, and I am available around 3–4 hours per day on average, with a rate of $30/hour. Sincerely, Oleksandr

***KICAD*** KiCAD-focused reviews for STM32/ESP32 boards with fast, same-day tasks catch my eye. I recently led schematic+layout QA for a 4-layer prototype, catching 12 issues pre-order. Plan: - Review schematics/layouts for DRC and BOM status. - Verify footprints and KiCAD consistency before release. - Deliver fast fixes for same-day task requests. Clarifying question: What is your preferred model for same-day tasks: defined per-ticket scope or a prioritized backlog, and what is your tolerance for last-minute changes?

KICAD Hi, Quantum Code Solutions is available to provide detailed PCB design reviews, component availability validation, and end-to-end KiCAD hardware development for your consumer electronics projects. The core of reliable PCB design—especially for STM32 and ESP32 platforms—lies in meticulous trace routing, stackup configuration, and verifying pinouts and footprints prior to fabrication. We bring hands-on experience in KiCAD for schematic capture and layout, ensuring all boards pass thorough design rule checks (DRC) and manufacturing review before ordering. Recently, our team delivered complete hardware design packages for ESP32 and STM32-based consumer devices, conducting full schematic reviews and multi-layer layout optimizations. We performed component availability checks, generated production-ready fabrication files (Gerbers, BOM, CPL), and validated signal paths to avoid costly board spins. Our rigorous review process eliminated footprint errors, resolved routing bottlenecks, and enabled rapid same-day task turnarounds during active prototyping. Our rate is $40/hr, and we are available for 4 hours per day (20 hours per week) with daily same-day turnaround on small tasks. Let's discuss in more detail now. Reach out to initiate a conversation! Best regards, Quantum Code Solutions

@eshmumkhan

KICAD⭐⭐⭐ Hi, I understand you need an experienced hardware engineer for a part-time role doing detailed PCB design reviews, schematic and layout validation, component availability checks, and eventually full PCB design and hardware testing. This fits what I do, and I can work the way you've described: quick turnaround, same-day tasks, and no AI-generated work. I work in KiCad daily and can review schematics and layouts for the issues that actually cause board respins, including power integrity, decoupling placement, grounding, differential pair routing, trace width versus current, creepage and clearance, thermal relief, connector pinouts, and BOM mistakes. I'm comfortable with EasyEDA as well, and I can handle non-Altium projects without issue. I've worked mostly on STM32 and ESP32 consumer electronics, with some experience in high-speed digital and power circuits. I can also help with component sourcing checks, footprint verification, and basic firmware if useful. My hourly rate is [Your Rate] USD, and I can commit [X] hours per day on average, comfortably in your 5–10 hours per week range with room to grow. I have no problem starting with small tasks so you can evaluate my work, and I'm available to respond quickly during your working hours. Happy to share examples of boards I've designed or reviewed, and I'm fine working under your time-tracking setup until trust is established. Thanks

@sufyanasmat38

KICAD Hello, I have hands-on experience working with KiCad for schematic and PCB layout reviews, component selection, BOM checks, power management, and embedded hardware design. I can carefully review designs before fabrication, identify potential electrical or layout issues, verify component availability, and handle complete PCB design when needed. I’m comfortable working with STM32 and ESP32 based electronics and can also support hardware testing and debugging. My hourly rate is $25/hour, and I’m available 4 to 6 hours per day with quick turnaround for smaller tasks.

@jayd058

***KICAD*** I’m interested in starting with your small trial tasks and proving the quality of my work through careful reviews, clear issue reporting, and fast turnaround rather than making unsupported claims about hardware experience. My background includes CAD, 3D CAD, product design, and detailed design review work, and I’m comfortable working methodically with schematics, layouts, component documentation, and design constraints while being transparent about anything outside my experience. I can work at 15$/hour and am available around 8 hours per day, with the responsiveness needed for same-day smaller tasks. I’m also comfortable using Freelancer’s time tracker and working alongside experienced engineers who expect precise, verifiable work. I’d be happy to begin with one of your smaller PCB/CAD review tasks so you can evaluate my attention to detail before increasing the workload. Best, Jay.

@Aaleen110

The 4-week delivery window for PCB reviews is the main constraint here, so I will prioritize that. I will conduct schematic reviews using Altium Designer, checking for design rule violations, component selection errors, and signal integrity issues, and also review the PCB layout in parallel, confirming trace widths, clearances, layer stackups, and power/ground plane strategies to catch potential manufacturing or performance problems before board spin. For full PCB design, I will use KiCad for schematic capture and layout, generating Gerber and drill files. Component availability is a real concern for new designs so I will assume we can source components from Digikey or Mouser, and will select parts with good lead times and multiple suppliers unless you specify otherwise. What are the typical board sizes and layer counts you work with for new PCB designs? I have a 5.0 rating across 10 reviews on here, and Preferred Freelancer status. I need your approval on the proposed approach before starting.
