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.

We sell trucks and want to use this platform so that users can login, search for troubleshooting issues and use an AI Agent that can search in a 50 page manual for possible solutions.

Investor Pitch Deck Designer for Consumer Tech Startup

We are looking for an experienced investor pitch deck designer to create a new fundraising deck from scratch for Toggle, an early-stage consumer technology startup. Toggle is developing a physical product and companion platform designed to help people deliberately put their devices down together and create more opportunities for real-world connection. We have developed the proposition, product concept, brand, commercial model and fundraising strategy, and can provide all of the underlying information, imagery and supporting material. What we are looking for is someone who brings genuine investor pitch-deck expertise, not simply graphic design skills. We want you to help determine how the story should be structured, what an investor needs to see, what should be prioritised, what should be removed, and how the narrative should flow. We do not want to prescribe the number or order of slides, we want your expertise to guide that. Visually, we are looking for something premium, minimal and confident, with the simplicity and discipline associated with high-end consumer technology presentations. Strong typography, space, varied layouts and powerful use of product/lifestyle imagery where appropriate, rather than a conventional corporate PowerPoint aesthetic. We are currently preparing to raise £300,000 through SEIS and have Advance Assurance. We can provide our existing materials as background information only, but this should be treated as a completely new deck rather than a redesign of an existing presentation.

Experienced AI (Outbound) Telemarketer

I have been managing outbound telemarketing teams in the UK for over 20 years, up until 2024, and have developed and taught a highly structured sales process that has been very successful. Over the past few months, I have been working towards rebuilding our direct sales operation without the challenges and management requirements associated with running a traditional telemarketing team. Our primary objective has been to develop an AI outbound telemarketer that can replicate our structured sales process and deliver conversations to the required standard. Unfortunately, two different developers have attempted the project but have been unable to achieve the level of accuracy, timing, responsiveness and natural conversation flow required. The current system is approximately 98% complete and the dashboard and backend are already in place. We are currently using Twilio and ElevenLabs. I believe the remaining issues can be resolved by someone with the right specialist experience in AI voice agents, telephony integration and real-time conversational systems. Before we arrange a meeting, we would like you to review the project materials, including: 1. The written sales pitch, which follows our structured 5-step methodology. https://docs.google.com/document/d/186JBo-MP2vTrKIwRyYD3minFKSU8JOisCAX2y-AMcDU/edit?usp=sharing 2. A verbal role-play recording demonstrating how the pitch should be delivered. https://drive.google.com/open?id=1ldPRd-8Dcfc6v1zg7qEyDISqXZ4a8gmg We would like to hear from developers who have genuine experience in building and optimising outbound AI telemarketing or conversational voice systems. When responding, please provide: * Examples of relevant AI voice or outbound telemarketing projects you have completed. * Details of your experience with Twilio and ElevenLabs. * Examples of systems where you have resolved issues involving response timing, latency, accuracy or conversational flow. * Links to relevant work, demonstrations or case studies, where available. * A brief explanation of how you would approach reviewing and improving an existing system that is approximately 98% complete. We are specifically looking for someone with proven, relevant experience rather than someone learning or experimenting with AI voice technology for the first time. Please review the written pitch and verbal role play before responding. We look forward to receiving your review and examples demonstrating your relevant experience. Due to the number of enquiries we receive, we will not respond to applications that do not include relevant examples of previous work and experience. The payment stated is not relevant.
