<h3>About the Role</h3>The world is in a waste crisis. Currently we produce 2.1 billion tons of solid waste per year. Data collection of the waste we produce is non-existent, meaning no systematic transparency and no accountability. It means that recycling targets are not upheld, dumping of waste into our oceans remains nobody’s responsibility, recyclables get sent to landfill or incineration, and producers have little visibility of how their packaging performs at end of life. Recycling rates remain at 10% and, unless we change, by 2040 the plastic stock in the ocean will have quadrupled - a problem that already costs society $1.5 trillion each year. Our mission is to increase transparency and automation in waste management to accelerate the circular economy. Greyparrot's camera and AI systems generate granular, real-time waste composition data across facilities worldwide. That data is only valuable if it can be turned into insight that clients trust and act on. We are looking for a Lead Data Scientist to act as the “engine room” of our data methodology, transforming raw computer vision outputs into insights the industry can rely on. The near-term priority is delivery; owning the contracted Deepnest client analytics, the reports and data clients have paid for, shipped on time and to a high standard. The metric engine work is what makes delivery scalable and trusted; developing the statistical methodology that turns raw computer vision outputs into defensible, quantified waste metrics. Both matter from day one. Longer term will support other customer &amp; marketing facing work as well.You will report directly to the CTO and have one direct report, Data Analyst, with scope to grow as the business scales. You will sit alongside the Head of Data R&amp;D who owns longer-term structural research upstream of the metric engine. The data is physical-world data: noisy, incomplete, and derived from computer vision models running in live recycling facilities. This is not a clean-warehouse role. It suits someone who treats messy data as the problem to solve, not a reason to wait.This role will ideally be based in our London office at least one day a week, and reports to our CTO. <h3></h3><h2>Outcomes</h2>These are the results you will be held to. How you achieve them is yours to figure out. 1.  The metric engine advancesThe next iteration of Greyparrot's statistical modelling framework is implemented; strengthening how we reconcile process flows, extrapolate across coverage gaps, and quantify confidence in outputs. At 12 months, a credible path toward a confidence-aware, probabilistic foundation is underway. The methodology is documented, defensible, and ready to be productionised by ML Ops. 2.  Contracted deliverables ship on time, every timeDeepnest clients receive their analytical reports and insight outputs to a consistently high standard and on schedule. The methodology behind the numbers is defensible, the findings are actionable, and clients trust what they receive. There are no surprises at delivery. 3.  Insight delivery is repeatable, not heroicA documented framework - templates, quality standards, methodology - exists so output quality does not depend on starting from scratch each engagement. The process is written down, transferable, and does not live in your head. 4.  R&amp;D and delivery are in syncThe Head of Data, R&amp;D has a clear, consistent picture of which model outputs translate to client value. You provide that feedback loop reliably, and it shapes what gets prioritised on the research roadmap. There is no gap between what the models produce and what clients actually need.<h3>Experience &amp; Background</h3><ul><li>Physical-world data: 5+ years in data science working with large-scale, noisy real-world data - environments where data quality and fail modes are constant challenges.</li><li>Background in high-volume, complex real-world data industries: sustainability, waste and circular economy, satellite and geospatial, weather forecasting, industrial IoT, manufacturing, is a bonus.</li><li>Deep learning familiarity: A strong practical understanding of the implications of working with data derived from deep learning models; specifically the nuances of integrating computer vision outputs into broader statistical simulations.

Currently, our camera system and AI software are deployed in recycling plants and waste facilities around the world to measure material flows and provide waste analytics. We have compiled a team of experts to deploy our technology and we’re looking to expand our team.

Greyparrot provides AI-based waste recognition software to power next-generation smart systems that will monitor & sort waste at scale. Our mission is to digitise waste & create a world where waste is captured & reused in the most effective way. Our vision is of a fully digitised, automated and transparent waste system to unlock the financial value of waste, which will in turn keep our planet clean for generations to come.
