Electrical Engineering Jobs

I’m looking for a qualified electrical engineer to take my project from concept to a complete, permit-ready set of drawings. At this stage I only have the overall idea; there are no existing sketches or schematics you need to follow, so you’ll be able to recommend the best approach from the ground up. Here’s what I expect you to handle: • Discuss the scope with me (residential, commercial or industrial—still open) and establish the load requirements. • Produce a full set of single-line and wiring diagrams, panel schedules, load calculations and a bill of materials that meet the applicable NEC/IEC standards. • Include clear notes for lighting layouts, power distribution points and all branch circuits once we decide which areas I’m prioritisi...

I will send you the architectural DWGs for two single-family homes, each around 154 m², together with my hand-sketched electrical concept. Your task is to translate that sketch into clean, professional electrical layouts directly on the plans in AutoCAD. All outlet and lighting fixture types are already chosen, so you can focus on accurate placement, routing, and annotation. Please show every convenience outlet, switch, and luminaire, indicate circuit numbers, and clearly mark the panel board, service entrance, copper grounding rod, and meter position. Use standard, readable symbols and keep layers organised so the file stays easy to edit later. Deliverables • Finalised electrical plans in DWG (matching my title block and scale) • A plotted PDF for quick review (option...

I need a complete controller that will let our magnetic chuck automatically magnetise and demagnetise steel rings. The unit must run in fully automatic mode, triggered from a simple set of physical push-buttons on the front panel. Clear LED indicators should confirm current status, and the operator has to be able to dial the holding force up or down through adjustable strength settings. I’m expecting a turnkey package: electronic schematics, PCB layout files, firmware source code (C/C++ or suitable PLC ladder if you prefer), a concise bill of materials and basic assembly instructions. A short test routine that demonstrates a full magnetise–hold–demagnetise cycle will serve as acceptance. If you have experience with high-current power stages, H-bridge control, soft start ...

I need a technician who can take this job from bare walls to a fully operational surveillance system. The work starts with assembling and securing a tidy, service-friendly rack, then running and labeling all network cables—indoors through ceilings and walls, outdoors through weather-proof conduit—so every drop ends cleanly in the rack and at each camera mount. All cameras are IP units and must be mounted both inside and outside the building. They have to operate with night vision, motion detection and true high-definition footage, so lens alignment, focus and network bandwidth should be verified on site. Once physically installed, each camera should be patched into the switch (PoE where possible), added to the NVR or VMS, and tested for live view and recording. Deliverables...

I am building a small-scale oil-handling package and need a Siemens PLC program that keeps product moving efficiently while making sure tanks never run dry. The core of the job is to write, test, and document logic that optimises flow, pulls accurate readings from our flow sensors and low-level sensor, and then drives the valves, pumps, and any other actuators that respond to those readings. Everything must tie neatly into the HMI; I’d like operators to have both a touchscreen view and a secondary PC or hard-key option so they can work comfortably from the panel or the control room. The system’s sole purpose is process optimisation, so response time and deterministic behaviour are critical.

I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. Delive...

I have written a MATLAB code for the optimization of a battery swapping station (BSS) for a bus fleet for scheduling its charging to minimize its cost. I have made the same code on GAMS also. This code is for a 24 hour period and for 11 buses and 4 batteries on the BSS. My code is perfectly working when I am running it for 10 hours, 2 batteries on BSS and 3 buses. But when I am increasing the number of hours or buses or batteries then it start taking a more than 3-4 days to run and still running.

I already have a finished schematic and need it turned into a clean, production-ready two-layer board using KiCad. The goal is to squeeze the circuitry into the smallest footprint you can achieve while still respecting good layout practice, clear labelling and standard fabrication limits (0.2 mm trace / 0.3 mm via or better). Along the way please: • Follow KiCad 7.x (or later) so the files open smoothly on my end. • Keep component placement logical for hand or machine assembly; all polarized parts should have their orientation clearly silkscreened. • Route with balanced trace lengths where signals require it, add ground pours on both layers, and include generous test points for key nets. • Run electrical-rule and design-rule checks before handing the job off....

I am fitting out a 5,200 sq ft unit that will operate as a clinic and I need a complete drawing package that the local health authority can approve without revisions.
