Having just taken a job with Raytheon and lamenting my lack of success getting a top software development position in a startup a friend asked "What is needed for new startups?"
A top software development position in a startup wants several years of experience with AWS infrastructure and a comprehensive knowledge of JavaScript use (and packaging) in the backend (node.js) and the frontend (Angular, React, and sometimes Vue). The startup still want the other skills of scalable architecture design (processing and data), excellent written and spoken communication, and mentoring, but having these is not enough. I was also surprised that even startups that will hire remote staff still want that staff close to home base.
As to the Java language and its ecology, this has little interest for them. In fact, many of the infrastructure foundations that are today implemented in Java -- ActiveMQ, Kafka, Zookeeper, Tomcat, etc -- are being replaced with "lighter" Go and Rust implementations. And with the accelerating move to managed infrastructure startups care little about how these foundations are implemented. They would rather rent, eg, a queuing service from AWS or GCP, and let the provider worry about implementing turnkey, scalable performance.
Even Citizens Bank, after having recently become independent of the Royal Bank of Scotland, is replacing their Java J2EE implementation with an AWS hosted, node.js microserviced, and React front ends. I have even heard that some of their services are from a "bank in a box" supplier.
I don't disagree with these changes except for the unfounded confidence in JavaScript -- the one language to rule them all. I would not want to run my own data center and infrastructure anymore, either. Assuming, that is, I had the very sizable budget for it.
