Job Description

About the API Integration Developer Role at Robert Half

Join Robert Half's esteemed client in Torrance, California, as a Senior IBM ACE Integration Developer. This pivotal long-term contract position offers the chance to architect sophisticated integration solutions using IBM App Connect Enterprise (ACE) and WebSphere MQ. As an API Integration Developer, you'll bridge complex enterprise systems, ensuring seamless data flow across multi-tier applications. Ideal for seasoned professionals passionate about middleware, cloud deployments, and event-driven architectures, this role demands expertise in high-stakes environments where reliability and performance are paramount. With Southern California's innovative tech landscape, you'll contribute to mission-critical projects that drive business success.

Why This Role Stands Out

In today's digital economy, API integration developers are the unsung heroes enabling digital transformation. Robert Half specializes in placing top talent in such specialized roles, offering unparalleled exposure to IBM's ecosystem including Cloud Pak for Integration (CP4I). Expect hands-on involvement from design to deployment, with opportunities to optimize APIs for security and speed in production settings.

Key Responsibilities

Your day-to-day will immerse you in cutting-edge integration challenges:

  • Design and develop robust integration solutions leveraging IBM App Connect Enterprise and WebSphere MQ to fulfill diverse business requirements.
  • Deliver expert technical support and troubleshooting for IBM ACE applications across test and production landscapes.
  • Partner with cross-functional teams, business stakeholders, and external vendors to elicit precise requirements and orchestrate flawless integrations.
  • Craft, test, and deploy innovative components while enhancing legacy systems for peak efficiency.
  • Engineer enterprise-grade messaging infrastructures and scalable multi-tier applications using IBM ACE and WebSphere MQ.
  • Fortify secure endpoints and fine-tune API and messaging flow performance to meet stringent SLAs.
  • Harness middleware development tools and champion CI/CD pipelines with Jenkins, Maven, GitHub, and SonarQube for accelerated delivery.
  • Master event-based paradigms, including publish-subscribe models and synchronous/asynchronous communications.
  • Orchestrate deployments and management in cloud-native platforms like OpenShift and Kubernetes.
  • Pioneer implementations with IBM Cloud Pak for Integration (CP4I) and emerging technologies.

Required Qualifications

To excel, bring these credentials:

  • Deep expertise in IBM App Connect Enterprise (ACE) and WebSphere MQ for enterprise integration.
  • Proven hands-on development in EAI (Enterprise Application Integration) projects.
  • Strong command of CI/CD tooling: Jenkins, Maven, GitHub, SonarQube.
  • Practical experience with container orchestration via OpenShift and Kubernetes.
  • Familiarity with IBM Cloud Pak for Integration (CP4I).
  • Skills in securing endpoints, performance optimization, and event-driven architectures (pub-sub, sync/async).
  • Track record supporting production and test environments with minimal downtime.
  • Excellent collaboration skills for stakeholder and vendor interactions.

Candidates should thrive in dynamic settings, with 5+ years in IBM middleware development preferred.
