Staff augmentation · India

Hire Java Developers in India. Vetted talent. Clear timelines. Your tools and IP.

Staff pre-vetted java developers in India. Shortlists in 2-3 weeks, transparent engagement models and commercials, and engineers who embed in your team, not a separate delivery track.

Speed, vetting, and engagement from day one

Whether you need one senior hire or a small squad, we run staffing for founders and engineering leaders, not a job board for candidates. You get speed, vetting transparency, flexible engagement models, and commercials before interviews, not after.

Placement speed
2–3 weeks

Role intake, sourcing, and technical screen to a shortlist you can interview. Typical start within 2–4 weeks once you select a profile.

Vetting process
4-step screen

Stack and experience match, communication check, live technical with a senior reviewer, and reference verification before profiles reach you.

Engagement models
Flexible

Dedicated augmentation, contract staffing, or contract-to-hire. Engineers work in your repos, tools, and time zones with IP assigned to you.

Pricing range
Custom bands

Transparent monthly or hourly bands by seniority and stack. We quote before interviews so finance and engineering align on budget.

Technical depth

Deep-Dive Tech Stack

JVM backends hinge on how Spring services, Kafka flows, persistence, and containers interact. We match on the patterns you run so tuning, migrations, and event-driven design stay coherent from local dev through production on-call.

  • Spring Boot

    REST APIs, OAuth2 security, actuator health checks, and profile-driven config for environment parity. Under load they catch N+1 fetch storms, mis-sized thread pools, and actuator endpoints exposed without auth before customers do.

  • Kafka

    Producer acks, consumer group behavior, idempotent producers, and dead-letter topics with replay tooling. Offset lag, partition skew, and exactly-once semantics for billing events are debugged with intent, not broker configs copied from a tutorial.

  • PostgreSQL / MySQL

    JPA and Hibernate with explicit fetch plans and Flyway or Liquibase migrations reviewed for lock duration. Connection pools match RDS limits; indexes follow EXPLAIN evidence instead of Spring defaults that fail under traffic spikes.

  • Maven / Gradle

    Multi-module builds, BOM dependency pinning, and reproducible CI artifacts with SBOM output. Slow integration modules are isolated from fast unit-test loops so developers get signal without waiting on the full graph every commit.

  • JUnit & Testcontainers

    Integration tests against real Kafka and Postgres in CI. Mocks that pass while production fails are replaced with ephemeral dependencies that catch schema drift before merge.

  • Micrometer & tracing

    Metrics export to Prometheus, timers on critical paths, and trace propagation across sync and async boundaries. Dashboards tie to SLOs on user journeys, not vanity heap graphs.

  • Docker & JVM tuning

    Container-aware heap settings, layered JAR images, and GC choice matched to latency budgets. OOMKilled pods from heap limits that ignore cgroup boundaries get fixed at the root, not with bigger boxes alone.

  • Redis & caching

    Session stores, distributed locks, and cache-aside patterns with TTL and invalidation on write. Stampede and hot-key issues get tuned from metrics before Black Friday traffic, not after checkout latency spikes in production.

  • Hibernate & JPA tuning

    Fetch plans, batch inserts, and second-level cache where appropriate, with N+1 queries caught in review and integration tests. Lazy-loading surprises in async endpoints get fixed at the mapping layer, not with blanket eager fetch everywhere.

Java staffing questions we answer upfront

How do you handle time-zone crossovers?

We align 3–4 hours of overlap with US or EU core teams for standups, PR reviews, and incident calls. Async updates go to Slack or your tracker with written context so decisions don't stall overnight.

Do your engineers work in monoliths or microservices?

Both. We staff against what you run today: modular monoliths, service meshes, or a hybrid mid-migration. We don't force a rewrite to justify the engagement.

What is your code review process?

Every PR gets peer review from a senior engineer on our side before it hits your repo. We check test coverage, API contract breaks, and migration safety. Your tech lead stays the final approver.

Can engineers join our existing sprint cadence?

Yes. They use your Jira, Linear, or GitHub Projects from day one. We don't add a parallel process layer.

Who owns the IP and commits?

You do. All work lands in your repositories under your CLA or employment terms. We don't retain code or reuse your business logic across clients.
