Senior Middleware Architect / Engineer
Utility & Regulated Industry Integration Program
Engagement Overview
Our client is hiring 8–10 senior middleware engineers to staff a large, regulated utility client''s enterprise integration program, spanning grid operations technology (OT), smart meter/AMI data, outage management, billing, and enterprise IT (ERP/CRM). This is a mission-critical integration workstream operating under NERC CIP and related utility regulatory requirements. Engagement is structured 60% onsite (US) and 40% offshore (India), onshore-led with offshore-leveraged delivery. Client identity is confidential for external-facing postings; refer to it as "a Fortune 500 regulated utility client."
Key Responsibilities
• Design, build, and maintain middleware integration layers connecting OT systems (SCADA, smart meter/AMI, outage management) with enterprise IT (billing, CRM, SAP/ERP, data warehouse).
• Implement and operate enterprise integration platforms — MuleSoft, IBM webMethods/IIB, TIBCO, Dell Boomi, or Azure Integration Services (platform per candidate specialization).
• Build and maintain REST/SOAP APIs, event-driven architectures, and message queues (Kafka, IBM MQ, RabbitMQ) for real-time and batch data exchange.
• Ensure integration security, reliability, and compliance with NERC CIP and other utility regulatory standards.
• Modernize and troubleshoot legacy-to-modern integrations, including mainframe and SAP PI/PO connections.
• Partner with grid operations, billing, customer service, and data teams to translate business requirements into integration architecture.
• Produce architecture and data-flow documentation sufficient for audit and regulatory review.
Required Qualifications
• 12+ years of middleware/integration engineering experience, with demonstrable delivery in utilities or another regulated industry (financial services, healthcare, energy).
• Hands-on expertise in at least one major enterprise integration platform: MuleSoft, IBM webMethods, TIBCO, Boomi, or Azure Logic Apps/Integration Services.
• Direct experience integrating OT/SCADA or IoT/AMI systems with enterprise IT — non-negotiable for this utility environment.
• Strong API design (REST/SOAP) and event-streaming/message-queue experience (Kafka, RabbitMQ, IBM MQ).
• Working knowledge of regulatory/compliance frameworks relevant to utilities (NERC CIP) or equivalent regulated-industry standards.
• Bachelor’s degree in computer science, Engineering, or related field, or equivalent hands-on experience.
Preferred Qualifications
• SAP PI/PO or SAP Integration Suite experience.
• Cloud integration experience on Azure or AWS.
• Prior direct employment or delivery experience at a utility, energy, or critical-infrastructure company.
