Hire Java developers for enterprise and regulated systems

Pre-vetted Java developers who join your team and work to your client’s standards. Nearshore on UK hours, or onshore and security-cleared where the work needs it. Daily or hourly rates, no minimum term.

What a Java developer does

A Java developer builds and maintains back-end software in Java, the language behind much of the software in banking, insurance, government and large enterprises.

‍

On a delivery team, a Java developer typically:

  • builds back-end services and APIs with Spring Boot
  • designs microservices, and the messaging between them with tools such as Kafka
  • integrates with databases, legacy systems and third-party platforms
  • writes tests and works with automated build and deployment pipelines
  • upgrades older Java codebases and breaks monoliths into services

‍

Java developers usually work on larger, longer-lived systems, often for regulated clients. If you need back-end developers across several languages, see our back-end developers.

When to bring in Java developers

Java developers make the difference when an enterprise system needs more hands, or when the work has to meet a regulated client’s standards.

You’ve won a programme with Java work and nobody is free
The start date is set, and your engineers are committed elsewhere.
Client implementations keep pulling engineers off your platform
Each new client needs integration work, and the roadmap slips.
You’re breaking up a monolith
Moving to services needs people who’ve done it without stopping the business.
A Java upgrade can’t wait any longer
Older versions lose support, and nobody has the time to do the upgrade properly.
A regulated client needs integration work done to their standards
Their systems, audits and security rules set the pace.

Java developer profiles

Java work varies with the system and the client. These are some of the profiles we supply:

‍

  • Java back-end developer. Builds services and APIs in Spring Boot, and owns the data model behind them.
  • Java integration engineer. Connects systems with APIs and messaging such as Kafka, including legacy platforms.
  • Java modernisation specialist. Upgrades older Java codebases and moves monoliths to services, a step at a time.
  • Java tech lead. Sets architecture and standards, reviews code and leads a small group of developers.

‍

If you need a different mix, tell us what the work involves and we’ll match profiles to it.

How teams use Java developers

One Java developer or a whole team, for as long as the work runs. You can start part-time, for example three days a week moving to five, and scale down with two weeks notice.

Where our Java developers work from

Most work nearshore in Central and Eastern Europe on UK hours. Where a client needs people on site, in the UK or with security clearance, developers can work onshore. For US work, developers in LATAM work US hours.

FAQs
Java developers
How much does it cost to hire a Java developer through Brightbox?

Java developers are on daily or hourly rates, which depend on seniority and where they work from. Ask and we’ll send a rate card, usually within hours.

How quickly can a Java developer start?

Usually within days, rather than the months a permanent hire takes.

Do your Java developers work with Spring Boot, microservices and Kafka?

Yes. Tell us your stack and we’ll match developers with experience in it, including Spring Boot, microservices, Kafka and your cloud platform.

Can your Java developers work on regulated or public sector projects?

Yes. Where a client requires people who are onshore, on site or security-cleared, we supply UK-based associates who meet those requirements. Tell us the requirements at the start, so we match the right people. See our security-cleared government associates.

Can they help modernise an older Java codebase?

Yes. They can upgrade older Java versions and frameworks, and move parts of a monolith to services a step at a time, inside your team and your release process.

Java developer or back-end developer: which do I need?

If your systems run on Java, a Java developer brings depth in the language and its ecosystem. If you work across several languages, a back-end developer may suit you better.

Can a Java developer work remotely?

Yes. Most work remotely, nearshore in Central and Eastern Europe on UK hours, so they’re online when your team is. Where a client needs people on site, developers can work onshore.

Can we hire Java developers for just a few months?

Yes. There’s no minimum term, and you can scale down with two weeks notice. Engagements shorter than about six weeks rarely work, because onboarding takes too much of the time.

Who owns the code?

You do. Everything they build is yours.

How do you handle IR35?

We’ve worked both inside and outside IR35, and we work with a partner to help with status determinations when needed.
