About Shellworks
Shellworks is a London-based startup creating Vivomer, a revolutionary sustainable material made by bacteria that behaves like plastic but breaks down naturally in the environment.
About the Role
As a Manufacturing Development Engineer at Shellworks, you will pioneer the transition from concept to production for sustainable materials. Your work will focus on designing, prototyping, and validating innovative manufacturing routes for Vivomer, ensuring they scale effectively as a high-performance alternative to petroleum-based plastics. This is a critical role to contribute directly to combating the global plastic pollution crisis.
Responsibilities
You will lead and execute the following tasks:
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Lead early-stage manufacturing projects, including concept development, prototyping, equipment specification, and pilot validation.
- Act as the primary technical point of contact with co-manufacturers, ensuring that new processes meet strict quality and scalability requirements.
- Travel to partner facilities and trial sites to troubleshoot issues, resolve technical problems, and accelerate the deployment of new production methods.
Requirements
The ideal candidate will bring:
- A strong background in plastics and polymer processing, supplemented by hands-on experience with techniques like moulding, extrusion, or assembly.
- Expertise in mechanical engineering, with a thorough understanding of process fundamentals, tooling design, and the ability to prototype machines.
- A proactive mindset, comfortable with working through ambiguity, travel, and deploying in fast-paced, high-autonomy environments.

Why This Role Stands Out
- Work at the forefront of Vivomer, a ground-breaking material that mimics plastic performance but degrades naturally in the environment.
- Not merely optimize existing methods—build entirely new manufacturing processes and equipment from scratch.
- Join a tight-knit, mission-driven team comprising world-class experts in materials science and engineering dedicated to cracking the plastic waste challenge.
