# Senior Mechanical Engineer **Company:** [Recycleye](http://jobs.workable.com/companies/khJxD9g9Z3ejDpTycfm6zP.md) **Location:** London, United Kingdom **Workplace:** hybrid **Employment type:** Full-time **Department:** Technical [Apply for this job](http://jobs.workable.com/view/911b3ef9-d2e3-4591-9bb9-c133f6fabfea) ## Description **A little bit about us**  At Recycleye, we’re transforming recycling through advanced AI and automation. Our technology enables waste management companies to recover more material, more efficiently — turning waste into valuable resource.  Since launching in 2019, we’ve scaled rapidly, deploying our AI-powered sorting systems across Europe and the US. But the challenge remains enormous — globally, only 9% of plastic waste is recycled.  Our systems operate in harsh industrial environments, at high throughput, and under demanding reliability requirements. Solving these challenges requires thoughtful, robust mechanical engineering — and that’s where you come in.  **Why join Recycleye?**  This is a rare opportunity to join a scaling hardware company at the point where strong mechanical engineering will make a huge impact.  You won’t just design parts — you’ll help shape systems, define engineering standards, and build the foundations for scalable hardware deployed globally.  We offer:  - High ownership and autonomy   - Fast-paced scale-up environment with real engineering challenges   - Opportunity to shape processes, standards, and best practices   - Exposure to full product lifecycle and customer deployments   - Hybrid working (typically 4 days in Stratford office, 1 remote)    **The opportunity**  We’re looking for a Mechanical Engineer with 7+ years of experience to join our Production team and be the go-to mechanical engineer for Quantisort 2.0, our next-generation optical sorting platform.   This is primarily an office-first, hands-on role. You’ll support PMs and integrators with Quantisort projects, resolve technical challenges, and drive continuous improvements of performance, reliability, and scalability.   **Responsibilities Overview**  Quantisort 2.0 Product Ownership  - Act as the mechanical owner for Quantisort 2.0, driving the transition from configurable solution to standardised, off-the-shelf product  - Improve repeatability of third-party integration  - Drive product maturity and improve robustness and serviceability  - Develop scalable subassemblies to work for any deployment without bespoke engineering  - Work cross-functionally with software, hardware, operations, and production teams  - Travel to customer sites for installations and troubleshooting across Europe (once per month)  - Lead completion of the CE marking process for Quantisort 2.0, working cross-functionally to ensure compliance  Production, Manufacturing & Supplier Collaboration  - Mechanical design (3D CAD assemblies, 2D engineering drawings for fabrication, etc) to help create solutions and retrofit our technology into our client's facilities across Europe.  - Create installation guidelines, compliance matrices for integrators to adhere to, enabling our product to remain standard.  - Supporting all stages of the project lifecycle e.g. sales scoping, client layout, build, FAT, install, SAT, commissioning, after-care.  - Optimise designs for manufacturability, assembly, and integration (DFM/DFA)  - Optimise build/FAT processes through tooling, testing jigs, process, and design optimisation.  - Reduce part count, simplify assemblies  - Work with suppliers and fabricators to improve manufacturability and sourcing  - Play a role in transitioning the production team to an ERP system  - Lead value engineering and cost reduction initiatives  - Improve installation efficiency and build processes  Engineering Process & Best Practices  - Improve documentation, version control, and release processes   - Drive engineering standards and best practices   - Mentor junior engineers and contribute to technical reviews ## Requirements - Degree in Mechanical Engineering, or General Engineering with mechanical specialisation   - 7+ years of mechanical engineering experience delivering industrial hardware at scale  - Proven ability to identify and implement process improvements  - Experience working in fast-paced, iterative engineering environments  - Highly confident using Solidworks and PDM and producing drawings for manufacture.  - Strong systems-level thinking and problem-solving ability   - Solid understanding of manufacturing processes (fabrication, sheet metal, machining, assembly)  - Experience improving products in production or field-deployed environments   - Hands-on attitude: you are happy to go and sort out problems at client locations if need be or to assemble one of our products and do some troubleshooting when necessary.  - Strong communication skills and cross-functional collaboration  - Excellent skills in communicating technical information clearly to team members and key stakeholders.  It's a bonus if you have - SolidWorks certification (CSWP/CSWE), particularly sheet metal design  - Experience with industrial machinery, automation, or robotics   - Experience working on deployed customer equipment   - Experience scaling hardware from prototype to production   - Experience with pneumatics, conveyors, or material handling systems   - Startup or scale-up experience   - Experience mentoring engineers or leading technical initiatives   - A keen interest in solving the problems within the recycling industry.  _Even if you don’t tick every box listed above but are motivated by our work and believe you can make a difference on our team, we’d really love to hear from you – so please do apply and drop us a note about what you bring!_  _We are particularly interested in hearing from you if your background enables you to bring a different perspective to our team._ ## Benefits -
