Description
About Us
Pledge, now part of Blue Yonder, was a London-based climate-tech startup built to help companies take control of their logistics emissions. We developed a platform that enables businesses to accurately measure, manage, and reduce their carbon footprint, with a particular focus on transportation and supply chain emissions.
Following our recent acquisition by Blue Yonder, a global supply chain leader, we are scaling our vision and technology across industries and regions. We're now embedded within Blue Yonder’s Sustainability Product Team, maintaining our agile, mission-driven culture while benefiting from the scale and resources of a global enterprise.
Our goal is to power sustainable decision-making for logistics, procurement, and supply chain teams everywhere.
The Role
We are looking for a Senior Full-Stack Engineer with a strong backend focus in Python and experience across the modern cloud and web stack. This is an opportunity to shape the next generation of our emissions intelligence platform, contributing to everything from backend infrastructure and data pipelines to web-based tooling and APIs.
You’ll work closely with a cross-functional team of engineers, product designers, data scientists, and sustainability specialists. We’re looking for someone who is not only a strong coder but who thinks critically about maintainability, scalability, and software architecture, and who’s motivated by our mission to accelerate the world’s transition to net zero.
You’ll contribute to both product and platform initiatives: building end-to-end features, designing robust emissions models, and helping us evolve our stack, tooling, and engineering practices.
