<p>At Cocoon, we’re building low-carbon construction materials for the builders of tomorrow. Steel and cement together account for nearly 15% of global CO₂ emissions — and we’re tackling that head-on by developing the next generation of sustainable, high-performance materials.</p>
<p>We’re an early-stage, fast-growing company with a big mission and a small, hands-on team. Every day brings new challenges and new opportunities to make a real impact on the climate crisis.</p>
<h3>The Role</h3>
<div>We’re looking for a Laboratory Technician to support our researchers, manage day-to-day lab workflow, and operate and maintain a wide range of analytical equipment. You’ll help prepare samples and run characterisation methods, including XRD, PSA, ICP-OES, TGA, and isothermal calorimetry. You’ll be responsible for ensuring the lab remains organised, safe, and fully stocked.</div>
<p>You will also support the installation and commissioning of new sample preparation and analytical capabilities. By keeping equipment operating smoothly and data flowing reliably, you’ll play a central role in enabling Cocoon to accelerate research and development.</p>
<h3>Responsibilities</h3>
<h4>Laboratory Operations</h4>
<ul>
<li>Supporting researchers with their critical workstreams.</li>
<li>Sample preparation for material characterisation.</li>
<li>Conducting material characterisation work in the lab (XRD, PSA, ICP-OES, TGA, isothermal calorimetry).</li>
<li>Ensuring the lab is tidy, inventory is up to date, and consumables are restocked.</li>
<li>Managing QC processes from industrial trials.</li>
<li>Overseeing the installation, troubleshooting, and commissioning of lab equipment.</li>
<li>Operating and maintaining small-scale furnaces and Cocoon’s lab-scale prototype granulators.</li>
</ul>
<h4>Data Management&nbsp;</h4>
<ul>
<li>Developing a pipeline or dashboard for tracking analysis that is visible to the team.</li>
<li>Archiving material characterisation data effectively so all users can access it.</li>
<li>Data generation and cataloguing on Cocoon’s databases.</li>
<li>Generating data to support the commercial activities of the business</li>
</ul>
<h4>You’ll Succeed In This Role If You…</h4>
<ul>
<li>Bring experience in material characterisation from steel, cement, or a related field such as battery technology.</li>
<li>Have previous technician or lab manager experience.</li>
<li>Are comfortable organising large data sets.</li>
<li>Have an eye for detail and follow processes to the letter.</li>
<li>Thrive in a fast-moving, hands-on laboratory environment.</li>
</ul>
<h4>What We Offer</h4>
<ul>
<li>A central role in scaling Cocoon’s laboratory capabilities.</li>
<li>The opportunity to support formal research advancement across the team.</li>
<li>The chance to contribute data directly to demo-plant development and commercial work.</li>
<li>Clear growth pathways, including:
<ul>
<li>Conducting your own research.</li>
<li>Running onsite QC at pilot trials abroad.</li>
<li>Progressing toward Lab Manager and owning all H&amp;S.</li>
</ul>
</li>
<li>A competitive salary, company pension, £600 annual Learning &amp; Development budget, and 28 days' holiday.</li>
</ul>
