Electrical Engineering Jobs

I need a complete electric-motor design tailored for heavy-duty industrial machinery where sustained, high torque is the overriding requirement. The project covers the full engineering cycle—from concept sketches and electromagnetic calculations right through to detailed 3D CAD models, winding data, thermal analysis and a bill of materials ready for prototyping. Key objectives • Deliver continuous high torque at typical industrial supply voltages • Maintain reliability in harsh, high-duty-cycle environments • Meet common efficiency standards—compactness and energy savings are welcome bonuses, but raw torque matters most Your package should include: 1. Electromagnetic design files (Maxwell, Motor-CAD or equivalent) with clear performance plots 2. Mecha...

I’m building a large holiday light show and want one eye-catching feature: a flowing waterfall made of addressable LEDs where Kokanee salmon “jump” upstream at random intervals. I picture something in the middle ground—more dynamic than a minimalist outline, but not so intricate that it becomes impossible to wire or maintain. Most of the palette should stay in cool blues and greens so the water feels alive, while the salmon stand out with a contrasting hue only when they appear. What I need most is the xLights programming that brings this scene to life, plus guidance during physical setup so the finished piece looks and behaves exactly as it does in the sequence file. If onsite help isn’t feasible, detailed remote instructions or a live video walk-through wou...

I have a clear photograph of a double-sided PCB taken from an automotive control module and I need that board faithfully recreated from scratch. There is no schematic, component list, or labelled photo available—only the image itself—so the job calls for full reverse-engineering talent. What I need from you is a complete, manufacture-ready package: the schematic you derive from the picture, the routed board layout matching the original dimensions and hole placements, and production files (Gerber, drill, pick-and-place). A concise BOM based on the components you can visually identify will round off the hand-over. Accuracy is critical: track widths, via sizes, and copper pours must respect typical automotive reliability standards. You are free to work in KiCad, Altium, Eagle, o...

The existing PCB is functionally sound, but several components need to be swapped for newer equivalents and a handful of additional SMD parts must be integrated without altering the overall board footprint. The layout will stay largely intact; the job is focused on component-level edits rather than a full redesign. Key work: • Replace specified components with the updated parts listed in my BOM draft. • Add two new SMD devices (a low-profile DC-DC converter and a temperature sensor) into the current schematic and layout, observing clearance and impedance rules already in place. • Update the BOM, pick-and-place, and assembly drawings so everything aligns with these changes. Deliverables: • Revised schematic and PCB layout files (Altium Designer preferred, KiCad a...

I need an experienced, fully registered QS-level electrician who can remotely sign off the EV charge-point installations my team completes each week. All work has already been tested by our on-site electricians; your role is to review the paperwork, confirm compliance, and lodge the certificate through either the NAPIT or NICEIC portal—whichever you prefer. Because we fit chargers in volume (we have previously delivered projects for Octopus), speed and accuracy are essential. You will have online access to the completed test sheets, photos, and schematics for every job. Once you are satisfied that everything meets BS 7671 and Part P requirements, you simply upload the EIC/EICR and issue the confirmation back to us. Deliverables • Remote review of installation documents and i...

I’m in the planning phase of a new high-voltage substation build and need a seasoned scheduler to turn our engineering and procurement strategy into a transparent, logic-driven baseline in Primavera P6. The core of the work is two-fold: first, craft a complete timeline that reflects HV substation realities—long-lead equipment, outage windows, energisation milestones—and, second, run a thorough schedule quality-assurance pass (DCMA 14-point or equivalent) to prove the programme is sound. Although the master file will live in P6, familiarity with MSP is useful because part of the QA involves cross-checking imported data sets for consistency. Deliverables • Level 2/3 baseline schedule in Primavera P6 (.xer) plus PDF and XLS extracts • QA report high...

I need a seasoned AutoCAD Electrical pro who can jump straight into two top-priority items: building precise schematic & footprint symbols and configuring the automatic report engine so it spits out clean, reliable data every time. My projects follow a typical AutoCAD Electrical workflow—schematics first, panel layouts later—but the quality of the symbol library and the accuracy of the reports are what really drive my productivity. Here is what you will tackle first: • Design and manage custom schematic and footprint symbols, keeping the library tidy and searchable. • Set up automatic reports (BOMs, wire and cable lists, terminal plans, PLC I/O summaries, from/to reports) with custom templates that export smoothly to Excel or PDF. Beyond those priorities...

I’m looking for a qualified electrical engineer to take my project from concept to a complete, permit-ready set of drawings.

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...

Design and build a three-phase, 50 V / 30 A SPWM inverter tailored for an induction motor.

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 am already committed to Siemens hardware (S7-1200 series with a basic comfort panel) ...
