We are seeking a senior-tier Neuron Integration Specialist to own, secure, and modernize our enterprise application middleware framework. In this role, you will eliminate data silos by designing robust message-broker architectures, primarily using Neuron ESB alongside Microsoft Azure Integration services. Your mission is to build highly reliable, asynchronous messaging topologies that seamlessly bridge modern cloud services with complex on-premises legacy ecosystems.

Architecture, configuration, programmatic tuning, and day-to-day management of complex service integrations and asynchronous messaging channels leveraging the Neuron ESB middleware ecosystem.

• Integration Layer Analysis:
  Analyze architectural communication bottlenecks across distributed systems to design reliable enterprise integration flows and publish-subscribe messaging patterns.
• Transformation Architecture:
  Create data translation components, XML/JSON structural mappings, and message routing maps across disparate business domains.
• Service Endpoint Delivery:
  Program, test, and expose secure SOAP web service targets and decoupled RESTful endpoint interfaces on the service bus layer.
• Middleware Parameter Tuning:
  Configure, optimize, and manage runtime processing parameters, thread limits, message durability, and retry queues inside the Neuron ESB environment.
• Diagnostic Diagnostics Execution:
  Analyze integration transaction records, trace failing event chains, and resolve message blockage faults within production middleware infrastructure.

• Minimum of 5+ years of hands-on experience in enterprise integration, middleware engineering, ESB development or service-oriented architecture.
• Strong experience designing and implementing integration flows across distributed enterprise systems, including publish-subscribe messaging, service routing and event-driven communication patterns.
• Hands‑on experience with Neuron ESB, including runtime configuration, service bus management, message routing, retry handling, durability settings and middleware performance tuning.
• Good knowledge of SOAP web services, RESTful APIs, service endpoint configuration, interface exposure and secure service communication.
• Experience creating and maintaining XML/JSON transformations, structural mappings, data translation logic and message routing maps across different business domains.
• Strong troubleshooting experience in production middleware environments, including transaction tracing, message blockage analysis, failed event chain investigation and integration fault resolution.
• Good understanding of middleware performance parameters such as thread limits, retry queues, message durability, timeout handling and transaction processing behaviour.
• Ability to analyse architectural communication bottlenecks and propose reliable, scalable and maintainable enterprise integration solutions.
• Experience working with enterprise logging, monitoring, diagnostic tools and operational support processes for integration platforms.
• Ability to document integration flows, interface specifications, service mappings, operational runbooks and troubleshooting procedures.
• Ability to work independently as well as part of a distributed project team, collaborating with data engineers, software developers, architects, analysts and business stakeholders.
