About this role

Java / Spring engineers we place.

Java is what you reach for when the system has to run for ten years, scale to millions of requests per second, and pass an audit twice a year. Our Java engineers know that domain and ship for it — with Spring Boot for new services, JVM tuning when it matters, and the boring discipline that keeps enterprise systems alive.

Skills & expertise

What our java / spring engineers cover.

  • 01

    Spring & Spring Boot

    Spring 6, Spring Boot 3, Spring Security, Spring Cloud. Reactive (WebFlux) where it pays off, blocking where it does not.

  • 02

    Modern Java

    Java 21 LTS — records, sealed types, virtual threads, pattern matching. We use the language; we do not write Java like it is 2008.

  • 03

    Microservices & messaging

    Kafka, RabbitMQ, ActiveMQ, gRPC inter-service. Saga pattern, outbox pattern, idempotent consumers.

  • 04

    Persistence

    JPA / Hibernate done right (no N+1 surprises), JOOQ for type-safe SQL, MyBatis where it fits. Schema migrations with Flyway / Liquibase.

  • 05

    JVM tuning & observability

    GC profiling (G1, ZGC, Shenandoah), heap analysis, async profiler. Micrometer + Prometheus, OpenTelemetry tracing.

  • 06

    Build, test, ship

    Maven / Gradle, JUnit 5, Testcontainers for integration tests against real databases. CI on Jenkins, GitHub Actions, GitLab.

Hiring models

Three ways to engage a java / spring engineer.

  • Most popular

    Dedicated developer

    A senior engineer working 40 hours a week as part of your team. Daily standups, your tools, your timezone overlap.

    • Full-time on your engagement
    • Direct Slack / standup integration
    • Monthly billing on time-and-materials
    • Replacement guarantee in first two weeks
    Hire dedicated

  • Part-time / hourly

    Specialist depth on demand for short-cycle work — audits, spikes, code review, migration plans. Minimum 20 hours per month.

    • 20–80 hours per month
    • Hourly logging with weekly summary
    • Same vetting as dedicated engineers
    • Stop or scale up at any month boundary
    Hire part-time

  • Fixed-scope project

    Bounded engagement with a defined deliverable, milestone billing, and a clear exit. Best when scope is stable and timeline matters.

    • Fixed-scope SOW with milestones
    • Milestone-based billing
    • Includes hypercare on launch
    • Ideal for MVPs and audits
    Scope a project

What sets us apart

Why hire from Diglogic.

  • Audit-ready code

    Java engineers who have shipped through SOC 2 / PCI-DSS / HIPAA audits. They know what an auditor will ask.

  • Distributed systems literacy

    Idempotency, eventual consistency, retries, backpressure — design for failure, not just for the happy path.

  • JVM performance

    Heap dumps and GC profiles are read tools, not sacred mysteries. We tune what matters.

  • You meet who you hire

    No swaps.

  • Time-zone fit

    4+ hours overlap.

  • Replacement guarantee

    Two-week trial period.

Hiring process

Brief to first commit.

  1. 01

    Tell us the role

    Share the spec — required experience, stack, time-zone overlap, deadline. Ten minutes on a call or a written brief.

  2. 02

    CVs in 48 hours

    We send 2–4 pre-vetted CVs from engineers who actually fit, not just match keywords.

  3. 03

    You interview

    You run your own technical interview with the candidate. We facilitate; we do not edit.

  4. 04

    Onboard within 5 days

    Once you pick, the engineer is in your tools in five business days. Two-week trial period included.

FAQ

What teams ask before they hire.

Spring Boot or Quarkus / Micronaut for new services?
Spring Boot is the default for ecosystem maturity. Quarkus or Micronaut for native-image / cold-start-sensitive workloads — we make the call deliberately.
Can your engineers work in Kotlin instead of Java?
Yes. Many of our Java engineers ship Kotlin services interchangeably.
How do you handle migrations from older Java (8 / 11)?
Phased — first to LTS 17, then 21, with dependency upgrades and JVM tuning at each step. We do this without halting feature work.
