Senior Mechanical Engineer
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
