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.

Senior AI Developer / Engineer – Contact Centre AI Projects

We are seeking a Senior AI Developer / Engineer to support the discovery and potential development of two AI projects within a UK outbound contact centre. Our current contact-centre platform is MaxContact. The first project aims to explore how AI could enable us to analyse call recordings at scale for QA, compliance, sales and customer insights, moving beyond our current reliance on limited manual call reviews. The second project aims to explore the use of AI to handle the initial stages of outbound calls, identify non-prospects and transfer appropriate engaged prospects to human agents. We are deliberately not prescribing the technical solution or technology stack at this stage. We are looking for an experienced, hands-on developer who can understand our business objectives, advise us on how these could technically be achieved, explain what would be involved, and potentially build or support implementation of the agreed solution. What we're looking for: - Strong experience developing and deploying AI-enabled solutions in production environments. - Hands-on software development and systems integration experience. - Strong experience working with APIs and integrating third-party systems. - Ability to take a business problem and recommend an appropriate technical solution rather than requiring a predefined technical specification. - Experience with voice AI, telephony or contact-centre technologies would be highly advantageous. - Ability to communicate technical concepts clearly to non-technical stakeholders. - UK-based preferred, although we are open to suitable candidates who can work closely with a UK-based remote team. This is initially a discovery and scoping engagement, with the potential for development work to follow depending on the recommended approach. As the discovery stage is intended to establish the appropriate technical approach, development requirements, timescale and likely cost, we welcome proposals that include your usual rate and how you would suggest structuring the initial discovery engagement. Rate est. between £15 to £20p/h

Mechanical Engineering Innovation Project

I’m looking for an experienced mechanical engineer to undertake the development of an innovative energy-system project intended for small commercial applications. The project involves developing a novel mechanical energy conversion and storage concept, progressing from engineering analysis and design optimisation through CAD, simulation/FEA and ultimately toward a working, instrumented prototype and a validated design for scale-up. This is an engineering development and innovation project, not a feasibility-study-only assignment. I am not looking for an engineer whose primary deliverable is simply to review the brief, determine whether the initial concept is viable, and produce a development roadmap. The engineering assessment and calculation will naturally form part of the work, but it should be used as tool to develop, challenge, improve and optimise the concept. Where an initial assumption, configuration or component does not perform as required, I expect the engineer to investigate why, generate alternative solutions, calculate and compare options, and recommend or test improved approaches. The objective is to progressively engineer the best practical solution capable of meeting the project requirements, rather than stopping at a conventional feasibility assessment. I am looking for someone who is comfortable challenging conventional engineering arrangements while remaining firmly grounded in physics, safety and measurable performance. At this stage, I’m keeping the detailed operating principle and technical specifications confidential. My available engineering budget is £10,000, which I intend to allocate progressively against agreed engineering milestones and deliverables. Before I share the full Engineering Innovation Brief, I will require an NDA to be signed. If we agree to proceed, I will also require an Intellectual Property Transfer Agreement covering the project-specific work, designs and developments produced during the engagement. This is an innovation-led engineering project, so there will be uncertainty, iteration and technical challenges along the way. Please apply only if you are comfortable working in that environment and bring a positive, solution-focused mindset, curiosity, resilience and a willingness to test ideas, challenge assumptions and improve the design as evidence develops. *Please do not submit generic AI-generated responses to this advert. I am looking for a considered, personal response that demonstrates you have actually read and understood the project requirements. Copy-and-paste AI replies are immediately noticeable and, in my view, are unprofessional and show a lack of effort at the very first stage of the engagement. I am particularly interested in engineers who can combine analytical engineering capability with practical design thinking and prototype development. Thank you for your time.

Graphic Designer to ad Finish touches to a completed brochure

Our company brochure was recently designed and is finished to a very high standard there are quite a few grammatical errors that need addressing before going to print. because of the 5000 character limit I can not put them all in this description box and the brochure is too big to send over PPH. Due to me advertising previously and getting a lot of time wasters please supply your email address when applying so I can send you the documents all our communication and payments will be on PPH here is a small list of of the errors. there are 16 pages of errors but some of them pages have an error of one spelling mistake on the page. some of the pages have no spelling mistakes but need words deleting and grammatical reading issues. which will take minutes to do. here are some examples. PAGE 1 — Cover Current Professional Cleaning for the Modern Workplace This is actually a good headline. The cover has a corporate feel rather than looking like a domestic-cleaning leaflet. I would consider changing the subtitle slightly You could make the audience clearer: Professional Cleaning for London Workplaces & Managed Properties or Professional Commercial Cleaning Across London The current phrase “Modern Workplace” makes it sound mainly like an office-cleaning brochure, whereas the brochure also targets property managers, communal developments and other sectors. This isn't essential. The existing cover is perfectly usable. PAGE 2 — Contents There is an immediate spelling mistake: “End of Tennancy Cleaning” should be: “End of Tenancy Cleaning”. I'd also change: “Why Choose us” to: “Why Choose Us” And you may want: “After the Builders Cleaning” to become the more conventional: “After Builders Cleaning” or, better for corporate clients: “Post-Construction & After Builders Cleaning” Bigger strategic change Your contents currently treats every service almost equally. If this is becoming your commercial outreach brochure, I would reorder it so the most valuable services come first: About West Clean Our Team Office & Commercial Cleaning Communal & Property Management Cleaning Healthcare Cleaning Post-Construction / After Builders Cleaning End of Tenancy Cleaning Why Choose West Clean Client Testimonials Our Experience How We Work Contact That would match the market you're trying to win. PAGE 3 — About Us The opening says: “Drawing on more than 15 years in professional cleaning services…” That's good. But later you say 25 years combined experience. That's not necessarily contradictory, but a reader could wonder which figure is correct. I'd make the distinction explicit: “West Clean has more than 15 years' trading experience, supported by over 25 years of combined industry experience across our team.” That solves the issue. Current sentence “We provide a dependable and seamless cleaning service to a diverse portfolio of clients…” Fine, although I'd tighten it. Suggested version West Clean provides dependable professional cleaning services to businesses, property managers, estate agents and organisations across London. Then: With more than 15 years' experience, we understand that commercial cleaning is about more than appearance. Reliability, communication, consistency and accountability are equally important. That's much stronger commercially. Your present copy becomes quite long and generic. Testimonial attribution You have: “- Lauren Ouno App” I'd change that to something clearer: Lauren — Finance & Operations, Ouno App assuming that is accurate and you have permission. PAGE 4 — Our Team This page is fundamentally good. It currently says: “Each member is carefully selected, fully trained, and committed to upholding the highest standards…” Good. Later: “we use only premium biodegradable cleaning products.” Be careful with “only”. If West Clean ever uses bleach, descaler, specialist chemicals, solvents, disinfectants or another non-biodegradable product when required, the statement becomes inaccurate. I'd say: “Where appropriate, we prioritise high-quality, environmentally responsible cleaning products while ensuring the correct products and methods are used for each site.” More credible. I would add one commercial sentence “Our cleaning teams work to documented site specifications, with ongoing supervision and quality checks to help maintain consistent standards.” That appeals to facilities/property managers. PAGE 5 — Office & Commercial Cleaning This is one of your most important pages. The main copy says: “Each client is assigned a dedicated account manager and a trusted team of trained cleaners…” That's strong. I'd make this page even more B2B-focused. Add a small section such as: Suitable for: • Offices • Managed properties • Professional practices • Shared workspaces • Retail and commercial premises • Property-management portfolios
