Product design engineer needed

Product Design Engineer Needed – Small Flexible Consumer Product / CAD & Prototype I’m looking for an experienced product design/mechanical engineer to help develop a small flexible consumer product from an existing concept into an initial functional prototype. The product is a small, preferably one-piece flexible component containing very fine, soft internal features. It also incorporates a flexible split/opening which needs to open temporarily and reliably return to its original shape without permanent deformation. I’m looking for someone who has experience with: • Physical consumer product development • Flexible materials such as TPE, TPU and/or silicone • Small, fine flexible features • CAD for manufacture • Injection-moulded product design / DFM • Functional prototyping and design iteration This is not simply a CAD tracing/rendering job. I need someone who can help develop the geometry, material choice and functionality and advise how the design can eventually be manufactured at very low unit cost. I already have concept visuals and a clear functional brief, but these will only be shared privately after confidentiality has been agreed. Initial budget: £200–£300. This budget is for the first development stage only — feasibility/design development, initial CAD and ideally a functional prototype or prototype-ready design. Further development may follow if the concept performs successfully. Please include examples of any relevant work involving flexible moulded products, TPE/TPU/silicone, fine flexible features or injection-moulded consumer products. Please also confirm: • whether you’re happy to work under an NDA/confidentiality agreement; • what you could deliver within £200–£300; • whether STEP/STL/source CAD files would be supplied to me; • whether you have experience designing for injection moulding.

Structural Engineer

I'm looking for a structural engineer to carry out a wind load assessment and foundation/anchor design calculation for a stacked shipping container structure, with a stamped calculation pack suitable as formal sign-off. The structure: • Three 40ft high-cube shipping containers, stacked 3 high (9'6" / 2.9m height each, so approx. 8.7m total stack height) • Standard ISO steel construction, corner-casting to corner-casting stacking • Site located in Solihull, West Midlands • Open yard setting — no significant surrounding shelter from adjacent structures What I need: 1. Wind load assessment to BS EN 1991-1-4, appropriate to the site location and exposure category 2. Overturning moment and corner reaction calculation (uplift and shear) at ground level, and at each inter-container connection level 3. Foundation and ground anchor design — footing sizing and anchor bolt specification suitable for the calculated loads 4. A stamped/signed calculation pack I can retain as documentation I'm not converting these into habitable/occupied space but they’ll be used to house activated carbon and have an access gentry to change out dust filters, I want the installation properly engineered and documented given the height and wind exposure. Could you let me know: • Whether this is something you're able to take on • What information you'd need from me to scope and quote (site plan, container spec sheets, any ground condition info) • Indicative cost and turnaround time

I need RP voiceover of phonemes for a pronunciation app

Hi! I'm building a British English (RP) pronunciation-learning app and need a single native RP voice recorded for the app's sound library. I'm checking for standard Received Pronunciation specifically — no R sound in "rather"/"water" (non-rhotic), "bath" said with a long "ah" not a flat "a", a clear T in "water" (not "wa'er"), and the H in "have" kept in. If that sounds right, here's the job: About 380 short clips total: 88 isolated phoneme sounds (2 speeds each), 280 individual words, and 12 short phrases spoken at natural fast conversational speed Single voice throughout — one quiet room/session for consistency Delivered as WAV or M4A, 44.1kHz or higher I'll send the full word list and file-naming spec once we're ready to start recording This is for a commercial, paid app (subscription-based), not a personal project — so I need full commercial usage rights: a complete buyout of the recordings, work-for-hire, no royalties or usage caps, and no restriction on redistributing the audio inside a paid app. Please confirm upfront whether your standard rate includes that license or if a commercial buyout costs extra, so there are no surprises later. This could later lead to additional work if it were a success.

Filipino voices wanted for AI project - no experience needed

I'm casting natural-sounding native Filipino voices as part of a larger conversational AI project, and I'm specifically not looking for professional voiceover artists. I want people who sound like real people. The recording is entirely in Filipino. For this one I need female voices that read as roughly 20-30. Mid-range pitch, unhurried, soft, clear and warm. Filipino has to be your native language, spoken the way you actually speak it, not a learned or approximated accent. The only thing that matters is that you sound like a genuine human having a normal, unscripted conversation. If you've done a bit of acting or improv, that's a bonus, but it's not required. What I don't want is anything performed, polished or "announcer-y" - if you sound like you're reading an ad, this isn't for you. One requirement: you must have a decent microphone and a quiet, echo-free recording environment. No voiceover experience needed, but clean audio is essential. To apply, submit a proposal with a short, clear recording of yourself just talking naturally in Filipino, attached or linked. No script needed - talk about your day, a hobby, anything. Please don't say your name in the recording. Include where you're based in your proposal. Anyone selected will be signed under a clear, non-exclusive contract that strictly prohibits deepfakes, impersonation or any unauthorised use. Your voice will never be used without your prior written consent.

Chartered Geotechnical/Civil Engineer desk-based verification

A residential development in the South East has completed its foundation piling — thirty bored piles into chalk. The planning permission requires a verification report by a suitably qualified engineer. We are looking for a signed statement, one to two pages on your own letterhead, giving your professional interpretation of the completed records on two questions: Do the integrity test results mean/demonstrate that the installed piles are sound? Do the monitoring records demonstrate that the works caused no adverse ground or structural movement? Your opinion would be based on the documents already produced, which we will provide in full: low-strain integrity test results for all thirty piles, the complete structural movement monitoring log, the original geotechnical assessment, the approved construction method statement and the piling contractor's method statement. You are entitled to rely on the factual data in those reports — the survey measurements and test results — as accurate and complete. The judgement as to what that data demonstrates is yours. Requirements: CEng or CGeol chartership with membership number, and professional indemnity insurance covering a signed statement to a planning authority.

SCOPE OF WORK Review the existing webhook and Node.js implementation Receive and validate the webhook payload Transform the source data for processing Integrate the OpenAI API Generate an agreed structured JSON response Validate and safely parse the AI response Write the processed result to an existing Google Sheet Add focused error handling, retry behavior, and logging Add or update tests for the workflow Provide brief implementation notes

Create 4 x Short AI Product Videos From Existing Footage

I want to produce 4 animated product videos around 10 seconds long each, showing Skittles packs and skittles in an animated way. I have the attached basic footage showing the skittles packets in the set, and I have filmed what I can in camera, but a lot of it would have to be made up in AI. I also have the attached white background product images showing the pack and Skittles from different angles that can be used to help you. Here's a written example of the kind of animation I need, for example on the red pack: 'We want to highlight that they are 'giant' skittles. We will see the pack on the table, wobbling slightly (I have the footage for this) and as we hear a small 'boom' sound as well as the skittle falling (I don't have any audio). The frequency and volume of the sound increases. Eventually the skittles start dropping around the packet until they have covered a lot of the packet (I do have some footage of skittles falling on to the surface but they bounce off in random directions and we don't want this. I do not have the final footage of the pack mostly covered in skittles). I would like a hand to come in and take one out at the end (I only footage showing my hand but it needs to be changed to a nicer hand)' -Please note the other 3 videos will be completely different but the same complexity. -Please allow for a round of edits. HOW MUCH IN TOTAL TO COMPLETE ALL 4 VIDEOS?
