The opportunity
You'll join an established technology-led logistics business, working within the team responsible for connecting its platform to international delivery networks.
The work involves developing APIs and integrations that manage parcel shipments, labelling and tracking, while improving the reliability and scalability of systems processing high volumes of transactions.
