  • Analyze complex manufacturing and business requirements and translate them into scalable and supportable technical solutions.
  • Design, support, and troubleshoot integrations between MES, automated production equipment, ASRS/material-handling systems, databases, and other manufacturing applications.
  • Support and troubleshoot system integrations using technologies such as REST APIs, OPC UA, RabbitMQ, Windows Services, SQL Server, and other application or equipment interfaces.
  • Develop and troubleshoot SQL queries, stored procedures, data interfaces, and reporting solutions, including SSRS where applicable.
  • Investigate production issues across multiple systems, perform root-cause analysis, and coordinate resolution with the appropriate teams to minimize impact to manufacturing operations.
  • Participate in system integration testing, validation, deployment, change control, and documentation activities within a regulated medical-device manufacturing environment.
  • Work closely with Manufacturing, Engineering, Automation, Quality, IT Infrastructure, application teams, vendors, and other stakeholders.
  • Define and maintain technical documentation, system interfaces, support procedures, troubleshooting guides, and knowledge-transfer materials.
  • Identify opportunities to improve system reliability, monitoring, supportability, automation, and manufacturing-process efficiency.
  • Provide technical guidance and escalation support to the local IT support team for MES and manufacturing-system issues.

Qualifications

  • Bachelor's degree in Information Technology, Computer Science, Engineering, Information Systems, or a related field, or equivalent relevant professional experience.
  • Typically requires 6 to 8 years of related experience supporting enterprise, manufacturing, MES, or integrated business systems.
  • Strong experience with Manufacturing Execution Systems (MES) and manufacturing-system integrations.
  • Strong knowledge of SQL Server and SQL, including troubleshooting queries, stored procedures, data flows, and application/database issues.
  • Experience with integration technologies such as REST APIs, OPC UA, RabbitMQ or similar messaging technologies, and Windows Services.
  • Experience with Apache NiFi or similar data integration and data-flow automation platforms is preferred.
  • Experience supporting systems integrated with manufacturing automation, production equipment, material-handling systems, or ASRS is highly desirable.
  • Experience with SSRS or similar reporting technologies is preferred.
  • Experience working in a regulated medical-device manufacturing environment is highly desirable, including familiarity with system validation, change control, documentation, and compliance requirements.
  • Strong troubleshooting and root-cause-analysis skills across applications, databases, interfaces, infrastructure, and manufacturing equipment.
  • Ability to translate business and manufacturing requirements into clear technical requirements and solutions.
  • Strong communication and stakeholder-management skills, with the ability to work effectively across IT, Engineering, Automation, Manufacturing Operations, Quality, vendors, and corporate teams.
