Hire Java engineers

The stack most likely to be running something that cannot be switched off, which makes the screen as much about operational judgement as language.

What they are hired to build

The work, before the CV.

A role written against the work gets a better shortlist than a role written against a stack. These are what Java engineers are usually brought in to do.

Roles we recruit: Java backend engineer · Senior Java / Spring Boot engineer · Backend lead or principal engineer.

  • Spring Boot services and microservice estates
  • Systems with hard throughput or latency requirements
  • Banking, insurance and other long-lived regulated platforms
  • Modernising a monolith without a full rewrite

The technical screen

What the conversation actually covers.

Every candidate has a real technical conversation with an engineer who has done the job, and you get written evidence per competency. In Java, that conversation covers the following.

Usually assessed alongside: Spring Boot, JPA / Hibernate, PostgreSQL or Oracle, Kafka.

  • Concurrency: threads, pools, and what they have actually debugged
  • JVM behaviour under load — memory, GC pauses, and how they diagnosed one
  • Spring's dependency injection and transaction boundaries
  • Persistence and the N+1 problems that follow careless JPA
