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.
Interview Requirement Use Case Presentation:
Every candidate must present 3 real-world middleware integration use cases they personally designed or delivered, ideally in a utility or other regulated-industry setting. For each use case, candidates should address:
Business problem and context what systems needed to connect and why.
Technical approach and platform used architecture, tools, and integration pattern.
Integration complexity systems connected, data volume, latency/throughput requirements.
Outcome and business impact measurable result.
Compliance/security considerations addressed, if applicable (e.g., NERC CIP, data protection, access control).
