Job description

Senior Java Developer
Location: New Jersey | Type: Contract (C2C or W2)

Integration Architects places senior engineers on contract engagements with our client companies. We are building a roster of Java talent we can match to client projects as they come up.

You will design and build scalable backend services for our enterprise clients.

What you will do

  • Design and develop microservices and REST APIs
  • Own features end to end, from design through production
  • Optimize performance, scalability, and reliability
  • Integrate with databases, message queues, and third-party systems
  • Mentor on code quality, testing, and architecture

What you bring

  • 12+ years building production Java systems
  • Strong Spring / Spring Boot and microservices experience
  • Solid SQL and relational database design
  • Cloud deployment experience (AWS, Azure, or Google Cloud Platform)
  • Strong testing discipline (JUnit, integration testing) and CI/CD familiarity

How we work

  • You are placed on contract engagements with our clients, not parked in one fixed role
  • We market your profile. When a client need matches, we move fast, and you move fast with us
  • You respond quickly, communicate clearly, and can stand in front of a client without hand-holding
  • Low-drama, self-directed, gets it done. If you need a lot of managing, this is not your spot
