Stop paying for PCBs that “work on the bench” and die in the field. I’m Avi Gupta, an electronics and PCB design specialist with 11+ years of experience and 500+ boards shipped for IoT, industrial, medical, and consumer products. I turn your idea or rough prototype into production-ready hardware using Altium Designer and other industry tools. ✅ What you really get working with me • Designs aimed to pass EMI/EMC and safety – not just “it seems fine” • Architecture and layout that reduce respins, delays, and surprise costs • Clean, production-ready documentation your manufacturer can build from ✅ I’m a good fit if you: • Have an ESP32/STM32 (or similar) prototype and need a robust Altium design for production • Already have a board but are worried about noise, reliability, thermal issues, or compliance • Want a senior hardware mind owning electronics while your team focuses on firmware/apps ✅ How I can help 1. New product hardware design • System architecture and block diagrams (MCU, power, IO, connectivity) • Schematics in Altium (KiCad/Eagle possible on request) • Multilayer PCB layout with controlled impedance, length matching, solid grounding • DFM-focused layout so CMs can assemble and test smoothly 2. PCB review, cost-down & reliability upgrade • Schematic/layout review for SI/PI, EMI/EMC, grounding, protections • BOM and PCB cost reduction (alt parts, stack-up, routing optimizations) • Better thermal behavior and reliability for 24/7 environments • Moving you from “lab-only prototype” to “production-grade design” 3. Compliance-conscious, production-focused design • Design practices aligned with CE, UL, CISPR and EMI/EMC expectations • Grounding, filtering, shielding, creepage/clearance planning • Full outputs: schematics, PCB files, Gerbers, fab/assembly files, BOMs, PDFs ✅ Sample project types • ESP32-based LoRa/RS485 industrial IoT nodes • STM32 industrial controllers with isolated IO, 24 V domains, RS485/CAN • Raspberry Pi HATs with sensors, relays, RGB indicators and field wiring • High-voltage / high-power PCBs with isolated gate drivers and current sensing • Cost-optimized redesigns of existing ESP32/STM32 boards ✅ Tools & technologies Altium Designer (primary), plus KiCad, Eagle, EasyEDA, Proteus MCUs: ESP32/ESP8266, STM32, NXP, TI Interfaces: RS485, Modbus, CAN, Ethernet, SPI, I²C, UART, USB Wireless: Wi-Fi, BLE, LoRa (modules) Applications: IoT, industrial control, sensing, data logging, power and battery-powered products ✅ How I work • Hardware-first: solid architecture and PCB design, with basic firmware bring-up support • Clear communication: upfront questions, regular check-ins, review milestones • Production mindset: I design as if your board will be built at scale, even for 5–10 units If you need a reliable hardware partner for a real product (not a hobby build), message me with your idea, current status, and target timeline. Let’s make your hardware ready for the field.
An Electrical Design Engineer is a freelance specialist who designs, models, and documents electrical systems and circuits for products, buildings, machinery, and power distribution networks. From schematic capture and PCB layout to load calculations and panel schedules, an electrical design engineer translates functional requirements into manufacturable, code-compliant designs that perform reliably in the field.
Hiring a freelance electrical design engineer gives you direct access to senior-level engineering talent without the overhead of a full-time hire. Whether you need a single schematic reviewed, a complete building services design package, or an embedded hardware product designed from scratch, freelancers on Freelancer.com cover the full spectrum of electrical engineering disciplines.
Electrical design work spans low-voltage electronics through high-voltage power systems. The exact deliverables depend on the discipline, but a competent freelance electrical engineer typically produces a documented design package that a contractor, fabricator, or PCB house can build directly from.
Strong candidates are fluent in the industry-standard CAD and simulation tools that match your project type. Confirm tool proficiency early — design files are only useful if they open cleanly in your team's existing workflow.
Electrical design is foundational across nearly every engineered product and built environment. Freelance electrical engineers on Freelancer.com support clients in:
A portfolio is the single best filter. Ask to see redacted schematics, PCB layouts, single-line diagrams, or design reports relevant to your project type. Verify that the candidate has hands-on experience with the standards governing your jurisdiction — NEC and IEEE in the United States, IEC and BS 7671 in much of Europe and the Commonwealth, and CSA in Canada. A chartered or professional engineer (PE, CEng, EUR ING) credential matters most when the design must be signed and stamped.
Useful interview questions to ask a shortlisted candidate:
Adjacent skills that often complement electrical design include PCB design, embedded firmware development, mechanical CAD, FPGA design, control systems engineering, and technical drafting. Many freelancers offer combined hardware-firmware capability, which shortens iteration cycles for product development projects.
Freelancer.com gives you access to a global pool of vetted electrical engineering professionals, from independent consultants to chartered engineers with decades of industry experience. You can post a project on Freelancer.com and receive competitive bids within hours, compare portfolios across multiple specializations, and choose the freelancer whose experience most closely matches your scope.
Because clients set their own budgets and freelancers bid against the brief, you get transparent pricing that reflects the real scope of the work. Milestone Payments hold funds in escrow until you approve each deliverable, so design files, calculations, and reports are released on schedule and to specification. With talent available across every time zone, urgent revisions and design reviews can move forward around the clock.
Hiring an electrical design engineer through Freelancer.com is straightforward when you scope the work clearly up front. The clearer your brief on voltage levels, applicable standards, software outputs, and deliverable formats, the more accurate the bids you'll receive. Here's how to run the process.
The project post is the single biggest determinant of bid quality. A specific, well-scoped brief filters for engineers whose discipline genuinely matches your needs — power, controls, electronics, or building services. Head to the
Bids are short proposals, not just price quotes. A strong proposal from an electrical design engineer will demonstrate that the freelancer has read the brief, raised the right technical questions, and proposed a realistic approach. Read each bid carefully and shortlist candidates whose understanding of the design challenge matches your expectations.
Final selection combines proposal quality with profile evidence. For electrical design work, you want to see consistent quality across multiple past projects — not just one impressive sample. Pay close attention to written client reviews, which often reveal how the freelancer handles revisions, compliance feedback, and design reviews.
Timelines vary widely with scope. A single PCB schematic and layout for a small board can be completed in one to three weeks, while a full building services design package or a complex power systems study may run several months. Agree on milestones up front so progress is measurable.
Only licensed professional engineers can legally stamp drawings, and licensure is jurisdiction-specific. If your project requires sealed drawings for permitting or regulatory submission, filter for freelancers who hold a PE, CEng, or equivalent credential in the relevant region and confirm their license is active.
Electrical design engineers traditionally work on higher-power systems — power distribution, motor control, building services, and industrial installations. Electronics engineers focus on low-voltage circuits, PCBs, microcontrollers, and signal processing. Many freelancers cover both, but for specialized work it's worth hiring the discipline-specific expert.
No. A capable electrical design engineer will select components based on your performance, cost, and availability requirements, and deliver a complete bill of materials with manufacturer part numbers, distributor links, and alternates for parts at risk of obsolescence.
For focused deliverables — a schematic, a panel design, a load study, a design review — a freelance electrical design engineer is faster and more cost-effective. Agencies make more sense when you need a multidisciplinary team for an ongoing program. Many clients on Freelancer.com start with a single freelancer and scale up by hiring additional specialists as the project grows.
