How they approach a codebase they did not write
Most enterprise Java work is changing existing systems, not starting new ones.
BACKEND
Hire Java Developersfrom India, for your team.
Java engineers for services that need to be correct, observable and maintainable years after the people who wrote them have moved on.
WHAT THEY DOWhat our Java engineers
What our Java engineers
are responsible for.
Written as the work, not as a keyword list. If your role needs something outside this, tell us and we will say whether we can staff it.
- Build services in Spring Boot with clear module boundaries
- Work safely inside large existing codebases
- Handle transactions, concurrency and consistency correctly
- Modernize legacy systems without stopping the business
- Tune JVM and query performance based on measurement
EVALUATING CANDIDATESWhat to probe for
What to probe for
in a Java interview.
This is useful whether or not you hire through us. A better-run interview gets you a better engineer either way.
Their handling of transaction boundaries
The most common source of subtle data bugs in this stack.
What they would do first in a modernization project
Looks for someone who de-risks incrementally rather than proposing a rewrite.
THE TRAP
Years of Java experience can mean a decade of the same year repeated. Probe for what they have changed their mind about.
HOW WE SCREEN
Evidence, not keywords.
We assess Java engineers on reasoning within an existing system — a change with consequences — rather than a greenfield exercise that rewards the wrong instincts.

WHY TRUST A NEW FIRMWe are new.
We are new.
So we carry the risk, not you.
Hexalabs is early. We would rather say that than imply a history we do not have — you would find out anyway, and it would cost us the engagement. Instead, here is what we commit to in writing so trying us costs you very little.
A two weeks paid pilot
Start with a two-week paid pilot on real work from your backlog. At the end you decide whether to continue, with no further obligation and no notice period to serve. You will have seen the code, the communication and the pace before committing to anything longer.
Free replacement in the first 30 days
If an engineer is not working out in the first 30 days, we replace them at our cost, including the handover. You do not pay twice for the same seat, and you do not run the hiring process again.
Two weeks notice, always
Engagements run on two weeks notice. If it is not working, you are not trapped in it. We would rather you left early than stayed unhappy and told people about it.
You interview everyone
You interview every engineer before they join, and nobody is placed without your yes. Our screening notes come with each profile so you can see what we assessed and judge it yourself.
These terms go into your contract, not just onto this page. Ask us for them in writing before you commit to anything.
NEXT STEPTell us the role.
Tell us the role.
We will come back with profiles.
Two fields to start. The more you tell us about the work, the closer the first set of profiles will be.
A LITTLE MORE CLARITYGood questions.
Good questions.
Clear answers.
Still deciding? A short conversation is usually faster than another round of research.

Either. A single engineer joins your existing team under staff augmentation, working your process and your sprint. If you need the surrounding roles too — design, QA, DevOps — a dedicated team is usually the better shape, and we will say so rather than selling you more people than the work needs.
An overlap window with your working day is agreed before anyone starts, and it is written into the engagement rather than left to goodwill. Tell us the hours you need covered and we will tell you honestly whether we can staff them.
IP assignment is set out in the contract before work begins. Confirm the specific terms with us in writing — this is exactly the kind of thing that should never be assumed.
