Marketplace Development Manager
Salary
£40-£50k
Company Description
Material Index Ltd is a London-based climate-tech startup transforming the built environment through a large-scale material reuse marketplace. Backed by traction with industry leaders like British Land and Wates Group, they are "turning waste into assets" to tackle the 14% of global carbon emissions caused by construction material production.
Location
London, UK
Why this role is remarkable
- Join a mission-driven team working to solve a massive environmental crisis; construction accounts for 50% of UK landfill and 14% of global emissions.
- Influence the growth of a platform modeled after industry disruptors like Vinted and Backmarket, but for the vastly larger construction sector.
- Work directly with prestigious real estate and construction firms including British Land and Derwent London to unlock material supply before demolition.
Job Description
You will lead the development of a category-defining marketplace for reclaimed construction materials. Balancing high-level growth strategy with hands-on execution, you’ll drive supply and demand, onboard key trade partners, and scale user engagement. This is a pivotal role for a self-starter eager to build a sustainable future in a multi-billion-pound industry.
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.
What You Will Do
- Take full ownership of marketplace development, steering its evolution and scaling both the supply and demand sides of the platform.
- Design and execute data-driven go-to-market strategies directly in the field to increase user acquisition, engagement, and inbound enquiries.
- Identify and onboard key trade partners, ensuring high-quality stock is actively managed and continuously uploaded to the platform for resale.
The ideal candidate
- A strategic yet hands-on leader who can move seamlessly from long-term growth roadmaps to daily execution and deal management.
- Deeply sustainability-minded with an understanding of building material resale values and the practical challenges of material reuse.
- A resourceful relationship-builder with an agile mindset, ideally with a background in construction, fit-out, or demolition industries.
