Java backend and full-stack engineers. Planning millions of products across factories and warehouses, tracking shipments and running ports and fleets are large enterprise services. Java engineers build them, most of all at Blue Yonder, and at the shipment-tracking company project44, the hospital-supply network GHX and the port and terminal software company Kaleris. They are the most common opening, about twice their usual weight. The postings require Spring Boot, Hibernate and Kafka on Azure or AWS, and many roles are full-stack with React.

Cloud and DevOps engineers. Blue Yonder runs its suite as a cloud service for large manufacturers and retailers, and it hires most of the cloud engineers here, in Python with Kubernetes, Terraform and Argo CD on Azure. Cloud engineers hold about their usual place overall, and well above it in planning.

.NET engineers. GHX, Cencora, one of America's largest distributors of medicines, Kaleris and Blue Yonder build parts of their software on the Microsoft stack, in C# with Angular, Entity Framework and Azure Service Bus. .NET engineers hold about their usual place.

Test engineers. Testers hold about their usual place, at the warehouse-robot maker GreyOrange, Blue Yonder, the mailing and parcel company Pitney Bowes and the pharma track-and-trace company TraceLink. Many of the postings are for performance testing with JMeter or mobile testing with Appium.

JavaScript and Node engineers. Platform Science, a truck-telematics platform, and Blue Yonder hire Node engineers, with React, TypeScript and Kubernetes. They are about twice as common here as elsewhere.

Platform developers. Blue Yonder hires an unusual group of developers who build on ServiceNow and Workday and connect them to its own systems. ServiceNow developers are several times as common here as at a typical product company, almost all at that one company.

Robotics engineers. Warehouse robots that pick and move goods need software on the robot and in the fleet. The warehouse-robot makers, like GreyOrange, Botsync and ANSCER Robotics, hire firmware engineers, C/C++ engineers on embedded Linux and real-time systems, and Python engineers for robot software. Python backend engineers are about twice their usual weight here.

ML engineers. Kaleris hires most of a group of ML engineers who build models that optimise yards, cranes and schedules. The group is far more common here than elsewhere, and it takes juniors readily.

GenAI engineers. GenAI is less common here than at most product companies. Blue Yonder hires most of it, for planning agents, in Python with LangChain, LangGraph and MCP.

Also present. Data engineers, full-stack engineers, frontend engineers, far below their usual weight, Go engineers at the freight marketplaces, like Uber Freight and Porter, a few Salesforce developers and mobile engineers.

Rare here. SAP barely appears.
