Prototyping jobs

Job Description We are looking for an experienced hardware/embedded engineer for an upcoming wearable product development project. The product is a compact wrist-worn connected device, and we need someone who has previously taken a wearable or similar battery-powered consumer electronics product from hardware design through prototyping and manufacturing. The device will involve: - Custom PCB / electronics design - Bluetooth Low Energy (BLE) - Microphone + speaker / two-way audio - Low-power embedded firmware - Battery and power optimisation - Wireless charging - Compact wearable enclosure / CAD - Prototype development and testing - DFM and manufacturing handoff The final project will require complete production-ready deliverables including schematics, PCB/Gerber files, BOM, firmware...

...and when to propose a new component. **Auto Layout** — pages should resize correctly. No unnecessary absolute-positioned workarounds, broken fixed layouts or detached instances used to avoid proper structure. **Responsive thinking in Figma** — desktop and mobile frames should be intentionally designed from the same system, using appropriate constraints, components and responsive behavior. **Prototyping** — clickable prototypes for review, including hover/active states, sticky elements, scroll behavior and simple interactions where useful. **Developer-ready files** — clean layer naming, page and frame organization, consistent use of spacing and typography, and files that developers can inspect directly in Dev Mode. **Speed and consistency** — you...

I need a plastic bottle closure cap engineered with an internal cantilever snap-fit. The project starts with concept sketches and moves through a fully detailed 3-D CAD model, ready for rapid prototyping and eventually injection moulding. While I am flexible on the CAD platform—SolidWorks, Catia or even AutoCAD—the final geometry has to translate cleanly to common manufacturing workflows. Because the cap will be used on pharmaceutical packaging, every design choice must respect the relevant pharma-grade material and dimensional control requirements, including tight sealing performance and compatibility with tamper-evident or child-resistant secondary features that we may incorporate later. Once the form is locked, I also need a Design-for-Manufacture review that identif...

I’m putting together a basic auger-style spiral that will convey granular material, and I need a clean 3D model I can pass straight to prototyping. The geometry can stay simple—no elaborate fillets or assembly callouts—just an accurate helix sized to the dimensions we agree on, with a central shaft and the necessary clearance for smooth flow of the grains. Any CAD platform you’re comfortable with is fine; just export the finished part to a neutral format such as STEP and STL so I can drop it into other software. If you build it in SolidWorks, AutoCAD, Blender, or another package, that’s completely up to you. Deliverable: • Finished 3D file (STEP + STL) of the spiral auger, ready for fabrication. Once I approve the shape and overall measurements,...

I need a compact through-hole PCB laid out for a small consumer-electronics gadget I am prototyping. The board will stay simple—one or two layers, only a handful of standard components, no high-density routing or exotic footprints. Please take my rough hand-drawn schematic, translate it into a clean CAD schematic, and produce production-ready Gerbers. Any mainstream package such as KiCad, Eagle, or Altium is fine as long as the final files open without warnings. Deliverables • Editable schematic file • Board layout file • Gerber, drill, and pick-and-place outputs • Basic BOM with part numbers and footprints I will validate the design by loading the Gerbers into an online viewer and running DRC, so everything must pass standard clearance che...

What we’ll do in the call • Walk through the functional requirements I’ve drafted. • Brainstorm mechanisms, materials, and manufacturing approaches on the spot. • Capture quick screen sketches or block diagrams in the CAD tool you’re most comfortable with—SolidWorks, Fusion 360, Onshape, even tablet sketching works as long as I get a file afterward. • Flag the highest-risk areas and outline next steps so nothing important slips through...

...with no ornate flourishes—think subtle curves, balanced proportions, and smooth surfaces that translate well to precious-metal casting. You’ll receive my hand-sketches and basic dimensions; your task is to translate them into a fully detailed digital model, refine tolerances for typical fine-jewellery production, and supply high-resolution renders so I can review every angle before we move to prototyping. I’m comfortable with you working in Rhino, MatrixGold, or another professional jewellery CAD package as long as the final files arrive in STL for printing and 3DM or STEP for any further edits. Deliverables: • Finished 3D CAD model of the pendant and integrated chain loop • STL file optimized for 0.03 mm print accuracy • Native design file ...

...maze-shaped tiles that route creeps toward an opponent while simultaneously defending their own core. Matches last three to five minutes, so the gameplay loop must feel snappy, competitive and easy to pick up on a phone screen. I will provide a short design brief, sketches of the board layout, preliminary balancing numbers and mood-board art references once we start. From there the task covers prototyping through to a beta-ready build for both iOS and Android. Unity with Photon (or a similarly robust networking layer) feels like the natural tech stack, but if you have a better mobile-friendly multiplayer solution I’m open to it. Key milestones and acceptance criteria • Grey-box prototype that proves tile-placement, pathfinding and synchronous PvP all function smoot...
