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.

Business Development Marketer for new Enterprise Software

I’m looking for an experienced B2B business developer / direct marketer to help introduce SALIENT, a new enterprise intelligence platform, to branded companies across multiple sectors.

I need someone who can identify the right decision-makers, approach companies directly and start intelligent conversations with people in innovation, product development, R&D, strategy, marketing and emerging technology.

I’m looking for someone experienced, articulate and entrepreneurial who can understand an unfamiliar proposition, become enthusiastic about it and communicate that excitement convincingly. You should have experience opening doors through direct outreach, LinkedIn, email, telephone or your own network — ideally into recognised brands or technology-led businesses. The engagement will initially be 1–2 days per week on an hourly basis. SALIENT is founder-funded, so I’m building the commercial activity carefully at this stage, but I’m looking for quality rather than the lowest rate. There is clear scope for the role to grow if the pilot programme gains traction. If this sounds interesting, please tell me briefly: What types of companies and senior decision-makers you have approached Your experience generating new B2B conversations Why SALIENT interests you I’m particularly interested in hearing from someone who reads this and immediately thinks: “I know companies that should see this.” Part-time | 1–2 days per week | Hourly | Remote New Icons Innovation Foundry™ | Patrick Astwood, Founder

Freelance B2B Telemarketer – Niche Software for Photographers

Type: Freelance / trial basis to start (a few hours per week) Location: Remote Budget: Open – please submit your proposal and rate About the role I've developed specialist software for a very niche B2B market: school and nursery photography. The system works on a shared, multi-tenant model (similar in concept to Shopify) — photographers and studios use it to sell their photos online to parents. There are only a handful of companies worldwide offering software built specifically for this market, and the target list in the UK is small and well-defined (roughly 600–800 photographers and studios, ranging from sole traders to multi-photographer companies). This isn't a mass cold-calling job — it's a focused, relationship-led campaign into a tight, identifiable market. What I'm looking for I need an experienced telemarketer to help book demo meetings with prospective clients (studio owners/decision-makers). You'll be calling from a defined, relatively short list rather than working through huge volumes, so quality of conversation matters more than call count. To start, I'd like to run a small batch of test calls so we can both see how the approach lands and refine the pitch before scaling up. What I'd like included in your proposal Your experience with B2B/SaaS software telemarketing or appointment-setting How you'd approach a niche, low-volume prospect list (vs. high-volume cold calling) Your suggested process: research/warm-up, opening pitch, objection handling, and booking the demo How you'd handle common objections (e.g. "we already use a competitor," "not looking to switch software," or "too busy right now / it's our busy season" — we offer full setup support to make switching low-effort, so overcoming this one matters) Your proposed rate/structure (hourly, per meeting booked, or a fixed fee for an initial test batch) Availability for a short call so I can walk you through the product, its USPs, and likely objections before you start About the product (for context) Built from 20+ years of hands-on experience in the school/nursery photography market Sales performance comparable to one of the leading competitor products Key differentiator: significant time savings — one existing studio is already saving 20% on staff time using the software, alongside a range of additional features competitors don't offer We provide full setup support to get new studios onboarded, which helps overcome the "too busy to switch" objection common during their busy season Ideal candidate Proven experience selling or booking meetings for software/SaaS products, ideally B2B Comfortable handling technical/feature-based objections after a short briefing Organised and comfortable working from a defined prospect list rather than a script-and-dial-fast approach Available for a trial run of a few hours a week to start, with scope to grow if it works well If this sounds like a good fit, please get in touch with your relevant experience and how you'd approach this campaign.

HaloPSA Development - Ticketing Processes

We have a small helpdesk, and need assistance reviewing what we have set up with HaloPSA and utilising the Triage AI and anything else to help improve the flow of tickets we get logged. From assigning them, through to categorisation and what happens when tickets are closed. Its set up already and working, but tickets arrive and everything is manual.

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.
