Hire senior Java developers through Probegin — Spring Boot engineers for the systems that carry real load in banking, logistics and enterprise. Profiles within days, start within two weeks.
Well-bounded microservices and modular monoliths with Spring Boot 3, observability and sane service contracts.
Concurrency, caching and JVM tuning for systems where throughput is a requirement, not a nice-to-have.
Kafka, message brokers, SSO and the integration patterns Dutch enterprise estates run on.
Java 8-era estates brought to current LTS versions and containerized without stopping the release train.
Java remains the enterprise workhorse for load-bearing systems. For lighter services around a Java core, teams often add Node.js or Python at the edges.
The JVM systems where throughput and correctness are non-negotiable.
Kafka-based integration landscapes across enterprise domains.
LTS upgrades and containerization without stopping the release train.
Senior-heavy — our Java bench skews to engineers with banking, telecom and logistics backgrounds, matching the enterprises we've served for years.
Building AI into this stack? Meet our Implementeringsspecialist profile.
One specialist, embedded in your team, your standups and your tools — the classic direct model. Most placements run this way for a year or longer.
Two or three days a week for maintenance-grade or advisory work — you keep senior capability without paying for idle hours.
For outcome-scoped delivery, the specialist joins one of our implementation pods — priced on the result, not the hours.
What moves the rate: seniority, ecosystem scarcity (an architect-level profile prices differently than a generalist), and how long the engagement runs. For context, Dutch IT detachering averages about €65–150 per hour (ITRC, 2026); the direct nearshore model usually undercuts comparable local seniority meaningfully, since no layered agencies take margin. Exact all-in rates come with your shortlist in the intro call.
A 30-minute intake: the role, the stack, the team it lands in, the timeline it has to hit.
Two to three vetted Java developers from our 400K+ European network — within days.
Det er dig, der står for samtalerne og træffer beslutningen. Der er ingen pres, og vi har ingen bænk, vi skal tømme.
Kontrakter og indkøring er klaret. En prøveperiode på 60 dage, så risikoen ligger hos os.
Your Java developers work from our network across the Netherlands, Ukraine, Hungary, Romania, Poland and Bulgaria — all CET ±1, all fluent English (C1), all contracted and payrolled by Probegin so compliance stays our problem, not yours.
Yes — the bench skews to engineers who've worked in banking, telecom and logistics environments, the same profile our Dutch enterprise clients have drawn on for years.
Stepwise LTS upgrades, containerization and Spring Boot migrations are standard engagements — executed without freezing your roadmap.
Extensively; Kafka-based integration is one of the most common requirements in our Java placements.
Profiles within days, start within two weeks, 60-day trial as standard.
Spring Boot 3 is the bench default; Quarkus experience exists for teams chasing startup time and memory footprint in Kubernetes-dense estates.
The first 60 days are the proof: if the match isn't right, you say so and the placement ends without long-term obligation — or we replace the profile from the network. Most trials convert; the ones that don't cost you a conversation, not a contract.
Yes — that's the normal growth path. Many clients start with a single specialist and expand to two or five as the roadmap demands, keeping one contract and one point of contact at Probegin. Scaling down is equally simple, with reasonable notice instead of penalty clauses.
Probegin does. You get one Dutch counterparty and one invoice; employment, payroll and cross-border compliance for the specialist are our responsibility. That structure also keeps you clear of freelance-classification risk under Dutch rules.
Tell us the role today, meet your matches this week, have them on the team in two.
