What does a Java developer do?
A Java developer builds and maintains backend services, enterprise applications, and data-processing systems using Java and the JVM ecosystem. Strong Java developers are fluent in modern Java (records, sealed classes, pattern matching), use Spring Boot or Jakarta EE deliberately, understand the JVM's memory and GC behaviour, and design for correctness under concurrency.
Why Java is a strong choice for modern engineering teams
- •Default stack for enterprise backends, banking, telco, and large-scale Java microservices.
- •Spring Boot is the most productive Java framework for APIs, batch jobs, and event-driven systems.
- •Excellent tooling: IntelliJ IDEA, Maven/Gradle, JUnit, Testcontainers.
- •Mature concurrency and observability story for services at scale.
- •Long-term maintainability: Java is stable, backwards-compatible, and supported for decades.
Skills to look for when you hire Java developers
Modern Java (17+)
Comfortable with records, sealed types, pattern matching, streams, Optional.
Spring Boot / Spring ecosystem
Spring Boot, Spring Data, Spring Security, and the dependency-injection model.
Concurrency & the JVM
Threads, executors, CompletableFuture, virtual threads; knows how to read a heap dump or GC log.
Databases
JPA/Hibernate, SQL, indexing, and understanding of N+1 and transaction boundaries.
Microservices & messaging
REST, gRPC, Kafka or RabbitMQ; knows when to split a monolith and when not to.
Build & CI
Maven or Gradle, GitHub Actions or Jenkins, Dockerised builds.
Testing
JUnit 5, Mockito, Testcontainers for real DB/queue integration tests.
Cloud & deployment
AWS/GCP/Azure, Kubernetes basics, observability with Micrometer + Prometheus/Grafana.

- Explain the difference between @Transactional propagation levels and when each is appropriate.
- How do you tune JVM GC for a latency-sensitive service?
- How do you handle database migrations in a live Spring Boot app?
- Explain idempotency in an event-driven Java consumer.
- How do you test a service that talks to Postgres and Kafka?
- When would you pick gRPC over REST in a Java microservice?
- Describe a production incident you diagnosed on the JVM.
- How do you handle secrets and config in a Spring Boot deployment?
Frequently asked questions
How fast can I hire a Java developer through SquadXP?▾
You'll get the first pre-vetted candidate CV within 24 hours of the intake call. Most clients finalise a Java hire within 48 hours and onboard within the same week.
What if the first hire doesn't work out?▾
You have a 7-day replacement window, no questions asked. We'll start sending replacements the moment you flag it — no invoices, no friction.
Can I hire Java developers across US, UK and EU timezones?▾
Yes. Our network spans multiple regions, so we can match any timezone overlap requirement — from full US hours to split UK/EU coverage.
Is this contract, full-time, or project-based?▾
All three. We support short-term projects, long-term contracts, and contract-to-hire. Most clients start with a 3-month engagement and extend.
Do you handle payroll, compliance, and NDAs?▾
Yes. SquadXP handles contracts, NDAs, payroll, tax compliance, and invoicing. You get a single monthly invoice and don't have to manage any local entity.
How do you protect IP and sensitive data?▾
Standard NDAs are in place before any candidate sees your brief. We follow NDA, HIPAA-aligned, and ISO 27001 processes. All engineers work on dedicated, encrypted machines.
Can SquadXP build a full Java team, not just one hire?▾
Yes. If you need a team (Java engineers + supporting roles like DevOps or QA), we source as a unit, including a team lead, and onboard them together.
Do you provide Spring Boot and microservices experience specifically?▾
Yes. Most of our Java bench works in Spring Boot daily, with several engineers specialising in microservices, Kafka, and Kubernetes deployments.
Can you supply senior Java architects?▾
Yes. We have senior and staff-level Java engineers with 10+ years of enterprise experience, available for architecture, design review, and team leadership.
How much does it cost to hire a Java developer?▾
US senior engineers run $120–$180/hr; UK £90–£140/hr; EU €95–€140/hr; India $50–$80/hr for senior. Junior and mid scale down proportionally.
