Inxhinieri Mekanike Jobs

I am developing a lightweight detachable bicycle canopy designed for daily commuting in rainy weather. The goal is to create a compact aerodynamic canopy structure that can be quickly mounted on a bicycle and folded for easy storage. The canopy should be designed as a skeletal structural system (no fabric modeling required). The design must be created in Autodesk Fusion 360 as a parametric assembly with proper joints and mechanical relationships.

I’m developing an IoT device that will live permanently outdoors, so the enclosure must be tough st and attractive. The product needs to be C1D2 certified. I have sketched the basic board layout and I now need a mechanical engineer who can carry the housing from an initial requirements definition all the way through to documentation for mass production. Durability drives every decision: weather-proof seals, UV-stable plastic (I’m leaning toward a robust polycarbonate or glass-filled nylon), impact resistance, and the ability to maintain watertight integrity after repeated assembly cycles. If you feel a metal insert or composite gasket improves reliability, I’m open to those suggestions, but the core body should remain plastic to keep tooling costs and weight down. The w...

I need a seasoned Mastercam programmer to prepare reliable, shop-ready toolpaths for a steel production run. The models are already complete; what I’m missing is an efficient, collision-free machining strategy that maximises tool life and keeps cycle times tight. Your job is to: • import my 3D files, • create roughing, semi-finish and finish operations suited to steel, • select appropriate cutters and holders, • verify everything with dynamic simulation, and • deliver the final .MCAM file along with a setup sheet and post-processed G-code for a Haas VF series mill. I’ll provide the solid model, fixture layout and any in-house tooling constraints the moment we start. Once the first part passes inspection, the same program will run a short pro...

Greetings! I routinely handle projects that must meet Canadian and U.S. codes and, to keep pace with demand, I’m lining up a dependable engineer/architect who can step in whenever workload spikes. The collaboration will cover three recurring needs: drafting and design, permit-ready documentation, and sealed engineering calculations. Most drawings start in AutoCAD, move into Revit for coordination, and occasionally finish with quick SketchUp visuals for client presentations, so fluency in all three is essential. Typical assignments range from small commercial fit-outs to mid-rise residential work, and I’ll supply mark-ups, sketches, or point-clouds as the starting point. You would translate those into clean BIM models or 2D plans, run the structural or architectural calcs, and ...

I need an experienced Amada laser programmer who can quickly turn my part drawings into production-ready code for cutting metal in the ¼"–½" range. The role is remote and focused on creating nests using Amada's software. All work is for steel and stainless only—no plastics or wood—so your settings, pierce routines, and kerf offsets must reflect that. Parts arrive as DXF/SolidWorks files and are already dimension-checked; what I’m missing is the clean, efficiently nested NC program that will let my operators load it straight onto the machine and start cutting. I’m on a tight timeline and would like the first set of programs ASAP, ideally within the next day or two, with a short feedback loop for any tweaks. Deliverables • A...

I am ready to move ahead with the full design-and-build of a new PVC water main serving 20 residential plots on our development site off Bellswood Lane. The route runs entirely through soft soil, and each plot will need variable pressure so that owners can install everything from standard taps to high-flow garden systems without retrofitting pumps later. Here is what I need from you: • Detailed hydraulic sizing and layout drawings (AutoCAD / Civil 3D or similar) showing pipe runs, valves, hydrants, and individual plot branches. • Pressure-zone modelling (EPANET or equivalent) that demonstrates reliable variable pressure across all 20 plots when tied into the municipal feed. • Trench, bedding, and backfill specifications tailored to our soft-soil conditions, including a...

I need a complete structural evaluation carried out in ANSYS Workbench for a mechanical component that is already modeled. The task is strictly structural—no thermal or fluid-flow coupling—so please focus on static strength, deformation, and, if you judge it helpful, a brief modal check for natural frequencies.

I need a complete engineering package for a compact, stainless-steel (SS316) system that transfers two high-pressure gases—oxygen and a second gas—from 4 L, 1 800-2 000 psi supply cylinders into a 5 L storage tank. The small tank will serve purely for storage. Filling must occur in a defined sequence: first oxygen to a set intermediate pressure, then the second gas until the vessel reaches roughly 1 000 psi total. Gas purging is the preferred method for every line before and after each fill so that no pressure or cross-contamination remains prior to disconnecting the storage tank. The layout has to stay very tight—short runs only—and all wetted parts are to be SS316. Control and safety monitoring will be handled through a PLC with an HMI. Plan on integrating: &b...

I recently returned my diesel vehicle because it dropped into limp mode and, every time I locked it, the rear light mysteriously switched back on. The dealer now says the diesel injectors were faulty, claims they have been replaced, and insists both problems are resolved. Before I sign anything, I need an independent confirmation. A thorough diagnostic scan, a real-world test drive, and a close physical inspection should establish whether the car truly stays out of limp mode, the injectors are performing within specification, and the rear light behaves normally once the doors are locked. Please document the process and supply: • A brief written report summarising findings on the limp-mode issue, injector performance, and rear-light behaviour • Any live data or scan ...

For each geometric variant of the backbone I will supply (length, diameter, tendon-channel offset, bakbone type etc.), I need two clear results: • the exact tendon force applied, and • the resulting bend curvature radius of the backbone. Once all variants are simulated, please compare the force-radius trends and point out which configuration gives the most favorable bending performance so I can move forward with an optimal design. Deliverables must include the editable ANSYS project files, any ...

I am seeking an experienced mechanical or FEA engineer to perform a static structural finite element analysis (FEA) on a plastic lid component made from Polycarbonate (PC-110). The goal of the analysis is to estimate the force required to cause yielding or failure when a load is applied at the center of the lid panel. A STEP file of the part and a detailed instruction PDF are attached here. The simulation should apply a load perpendicular to the lid surface over a 1-inch diameter circular area at the center, while the perimeter of the lid is constrained as shown in the attached instructions.

I’m running a steady-state, two–phase condensation model for a single steam-carrying tube placed inside a rectangular duct through which the cooling medium flows. The goal is to quantify heat-transfer efficiency along the tube wall and map local condensation behaviour. All pre- and post-processing must be done in ANSYS Fluent – that is the environment my wider workflow depends on. I already have basic geometry and material data; what’s missing is a robust setup that captures phase change, solves for the temperature field on both sides of the tube, and outputs wall heat-flux, overall U-value, and condensate distribution with mesh-independent accuracy. Key points • Physics: two-phase (steam → liquid) condensation, steady-state, turbulent flow inside and ...

I am ready to move my mechanical wheel-end assembly from a rough concept to a fully filed U.S. and PCT application.

The concept is already sketched out, so you will start with my notes, preliminary sketches, and functional objectives, then refine them into a cohesive set of documents...

I’m upgrading a vehicle with a roof-mounted thermal imaging camera and need a streamlined enclosure that behaves a bit like a transformer: it must rise, give the camera a full 180° pan and at least 30° of tilt, then fold back and disappear under a low-drag cover when not in use. The core of the job is mechanical design. I’m after a concept that can be built either by 3-D printing or injection-moulding, so please keep draft angles, wall thickness and other DFM considerations in mind from the outset. Weather sealing, vibration resistance and smooth airflow over the stowed housing are essential, but I’m flexible on the exact material as long as it can survive sun, rain and highway wind speeds. I need sourcing motors, sensors, circuitry, the enclosure geometry...

My electric garage door, operated by a handheld remote, has suddenly stopped moving in either direction. I have already ruled out dead batteries in the remote, so the fault sits somewhere in the opener, safety sensors, wiring, or motor assembly. I need a technician who can: • Diagnose why the opener is unresponsive • Repair or replace the faulty component (limit switches, travel module, gear kit, safety eyes, etc.) • Test the door for smooth, balanced travel and reliable remote operation afterward Please bring the tools and common replacement parts you normally use for electric garage door systems; brand-agnostic expertise is fine as long as you can source compatible parts the same day. Once the unit is working again, a brief hand-off showing me how to reset limits or ...

I need a detailed CNC-ready design for a small metal disc that will act as a machine part inside one of our assemblies.

Deliverables • Final 3D model: I can import / export from sketchup • Motion proof: a short animation or screencast showing the linear travel throughout the full stroke • Manufacturing pack: dimensioned drawings for every aluminum part and a concise hardware list Acceptance criteria – Lateral drift no greater than ±1 mm over t...

I have built several tractor-mounted boom extensions and now I want solid, engineer-backed numbers on exactly how much weight each point along the boom can safely handle. The boom is welded from a 3/8" side-steer plate and a 2-1/2" × 2-1/2" × 3/16" square tube. From the plate it runs straight for 10 ft, then kicks up at a 30° angle and continues another 2 ft, giving a total length of 11 ft 10 in. Its primary job is lifting pole-barn trusses, so the working load will sit in the 500–1,000 lb range. I don’t have to satisfy OSHA, ISO, or any other formal standard, but I do want a clear, defensible safety factor. What I need from you is a straightforward structural analysis—hand calculations, FEA, or a mix—that tells me: • Ma...
