Two ways to hire a Java developer

Both are full-time, and you pay nothing until an engineer starts.

Subscription

$6,400-$9,600 a month per engineer, all-in

The engineer works only on your product, at least 160 hours a month, on our contract. We handle payroll, contracts, compliance and PTO and stay in the engagement after the hire. No placement fee, lifetime replacement, and a paid first week you can end with one day's notice. First shortlist within 47 hours after you confirm the role.

Permanent hire

12% of annual salary, $2,000 minimum

The engineer joins your own payroll, directly or through your employer of record, and you keep your own interview process. The fee is paid on the start date. First vetted candidates within 5 workdays of the search starting, and one free replacement within 60 days.

Subscription termsPermanent hire termsTeam cost calculator

How we check the level

In the full search, engineers take a timed video interview with questions written from your role brief and complete a scored written assessment. AI and a human expert review the results, and a talent manager signs off the shortlist.

How vetting works

What you see before your own interview

Each engineer on your shortlist comes with the recorded technical interview and its transcript, the scored assessment and the monthly rate, so you meet fewer people: on subscription, clients interviewed a median of 2 of our engineers per hire.

What the profile shows

What to ask a senior Java developer

Use these in your own technical round. Each one has a sign of a strong answer and a red flag.

Your Spring Boot 3 service calls a slow partner API from many threads. Would you switch to virtual threads, and what could go wrong?

A strong answerKnows that virtual threads (Java 21, spring.threads.virtual.enabled since Spring Boot 3.2) help code that blocks on I/O and do nothing for CPU-heavy work. Mentions pinning when a thread blocks inside synchronized on Java 21-23 (JDK 24 removed it with JEP 491), and that the connection pool or the partner's rate limit becomes the new ceiling.

Red flagSays virtual threads make everything faster, or plans to raise the thread count without asking what the database or the partner API can take.

A JPA endpoint that lists orders with their items got slow after launch. How do you find the cause?

A strong answerCounts the SQL first (SQL logging, Hibernate statistics or an APM trace) and suspects N+1 queries. Fixes them with a fetch join, an @EntityGraph, batch fetching or a DTO projection, and knows that a fetch join on a collection, combined with paging, makes Hibernate paginate in memory.

Red flagSwitches every relation to EAGER or adds a cache before measuring how many queries one request makes.

Two instances of your service read the same Kafka topic. How do you make sure a payment event is applied only once?

A strong answerExplains that a consumer group splits partitions between instances and that delivery is at least once, so duplicates appear after retries and rebalances. Makes the handler idempotent, for example with a unique event ID checked in the same database transaction, and knows Kafka transactions do not cover writes to an outside database.

Red flagAnswers that Kafka guarantees exactly once, so the problem cannot happen, or keeps the list of processed events in one instance's memory.

What did you have to change when you moved a service from Spring Boot 2 to 3?

A strong answerNames concrete work: the Java 17 baseline, javax to jakarta imports, Spring Security 6 configuration through a SecurityFilterChain bean, Micrometer Tracing in place of Sleuth, Hibernate 6 query changes. Describes how the change was tested and rolled out.

Red flagCan only say the version number in the build file went up.

Questions about hiring Java developers

How much does a senior Java developer cost through Wild.Codes?

On subscription, a senior engineer costs $6,400 to $9,600 a month, all-in, and the typical rate shown on this page is $7,840. There is no placement fee. A permanent hire costs 12% of annual salary, with a $2,000 minimum, paid on the start date.

Can I try a Java developer before committing?

On subscription the first week is a paid trial: you can end the engagement with one day's notice, no questions asked, and after that the notice period is 15 days. With a permanent hire you run your own interviews and take-home tasks, and one free replacement is available within 60 days of the start.

Can I still run my own technical interview?

Yes. The recorded interview and the scored written assessment come first, so your own round goes to fewer engineers: on subscription, clients interviewed a median of 2 of our engineers per hire. The questions in the section above are a reasonable base for that round with a senior Java candidate.

Which Java engineers do I see first?

When you describe the role, you first see pre-selected Java engineers from our ready pool who are free today, each with a monthly rate. If none of them fits, confirm the role and the full search starts: engineers record a timed video interview for your role, and a talent manager signs off the shortlist.
