Circuit Design Jobs
Circuit Design is the process of designing electrical circuits to create a complete electronic system. A Circuit Designer is responsible for designing circuits, testing the board and components through simulations, troubleshooting any errors, and even prototyping the board by manufacturing a few before completing the entire circuit accurately. Through this intricate process, a Circuit Designer will be able to optimize the design with their expertise and creative talent to push out an efficient product.
Circuit Designers are knowledgeable engineers with a high level understanding of electronics engineering and components that can be used in a circuit. They also possess analytical skills as they must be able to calculate loads, power consumption and sophisticated circuit architecture that involves cause and effects to produce sound results. With extensive knowledge of hardware engineering, Circuit Designers are responsible for hardware selection, board sizing, and routing of signals.
Here's some projects that our expert Circuit Designer made real:
- Automation systems built through electronic schematics
- Electrical systems concepted through hand sketches

Hire Circuit Designers
We have a schematic for a power supply design. We need the PCB designed in Eagle 7.5. BOM with package data will be shared. • Design will have to consider EMI/EMC aspect for certification. • There are approx. 48-50 unique components and about 115 total. • PCB is double-layered. Size isn’t a criterion, just not too large - 150mm x 150mm (f.e.). • You can use generic libraries and open-source libraries. Please check the attached pdf for more details.
Need an electrical designer to help document power board scopes with schematics for fit outs, More details will be shared over a chat
However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routing of electric...
If you are not an electronic engineer or have no clue about audio amplifiers, circuit designs please do not message, propose or bid. I need to design an all in one pcb board designed. It will have dual bridge rectifiers, choice of capacitors, for this build i need 20 x 2200uf capacitors, It will also have regulators to hold the voltages steady On the board it will have a single ended designed A class amplifier with speaker protection, this board will be ready to mount on a heatsink. It needs to be designed to fit to a particular size and needs to be designed in a clever way to minimize noise, heat and look good. I have attached some samples of the Regulator, amp and power supply design. This needs someone with experience in hifi, audio and amplifier design. Things like added e...
I need the Electrical Engineering expert for multiple jobs. Details will be discussed.
We are looking for someone with a design with them that can be tuned for our application. The product will be used in the furniture industry to provide backup power for motors. The engineer should help in the selection of the battery, design the PCB board. It should handle charging the battery, charge percentage monitoring and indication etc. We are looking for a small form factor Li-ion or Li-Polymer battery
Need to design a small project with physical pushbuttons etc relays control engineering
I would like stabilise PWM output of CH552 mcu
Design RF Power Amplifiers; use ADS
Hello, so this will basically be a project covering materials of Digital integrated service, and knowing how to use some CAD tools (electric, LTspice, and others) will be required to accomplish the projects.
Need an electrician to create a digital twin of electrical system in medium size buildings usiing a survey app on a smart phone. Also need submetering devices installed.
I'm looking for a freelancer who can design an analog electronic circuit for me. I need a customized design, with the circuit size to be miniature. My project requires the freelancer to have experience using advanced design technologies and processes. Someone with an impressive portfolio of related projects and an ability to create modern, efficient designs are highly desirable. Additionally, knowledge of desirable safety measures and versatility in the design process would be a plus.
Looking to have this board remade with all its components. It’s very simple. Thank you
I want to do a wifi button with a custom PCB using an ESP8266EX wifi chip.
The preliminar idea of the project is to buid a device based on a STM32, that controls a 4 inch LCD screen with RGB interface, with 2 to 4 serial data signals and 4 to 8 buttons. Design using easyEDA and prototypes made by jlcpcb. All this can be modified by designer advice. The work is design and test of the PCB. More details: - The work is to design PCB and schematic - The circuit has a 12V power source - The LCD is not deciced, but has to be high bright, problably RGB888, to be decided - The serial data bus is CAN - The LCD probably has a backlight power voltage of about 15v - I decided to use easyEDA because I know it, but also to be decided - I decided to use STM32 because it has support for CAN bus and RGB888, but again to be decided Regards
I need to redraw this diagram in Kicad. Currently, the board is on a single PCB, I would like each function to be on a single PCB connected to the next in a modular manner like the attached image. As per the attached picture, I would also like to change the flat cable insertion with an adapter. Each module must be 60mm x 60mm and use non-SMD components but the classic through-hole ones.
I want someone to help with the schemes of induction furnaces for melting metals, aluminum, copper, iron, made in China by main card MPU-2FK or MPU-6FK with the right equipment selection SCR,DC-Choke, snubber,capacitor,coil,
I'm looking for somebody that can make a PCB design for a flex cable

I am seeking assistance in designing 2 electronic devices. The level of difficulty should be that of 2nd year university program for electrical engineering. Therefore, students are welcomed to the challenge. BLACK CYLINDER A low voltage and extremely energy efficient electronic device (black cylinder) that is self contained in a a dimension no larger than two AA batteries stacked together vertically. This black cylinder should contain a magnetic proximity switch so that when the magnetic proximity sensor, external to but connected to the black cylinder, is in the closed state, the black cylinder should generate a Bluetooth Low Energy (BLE) signal with a value of '1'. When the magnetic proximity sensor circuit is opened, the black cylinder should send out a BLE signal with...
