Senior Mechnical Engineer London E15 2HU

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 U.S. 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.

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:

• 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.
• 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.
• Support 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.
