Job Summary
The “Business Systems Analyst” will be based in Libertyville, IL, reporting to Information Technology Manager.
In this role, you will be the primary local IT expert for our Manufacturing Execution System (MES) and its integrations. You’ll support a highly automated, regulated medical-device manufacturing site across the full solution lifecycle, from requirements and design through testing, validation, deployment, and production support. You will work closely with Manufacturing, Engineering, Automation, Quality, IT, and corporate teams to keep MES reliably connected to production equipment, material-handling systems, databases, and other manufacturing applications.
What a typical day looks like:
- Own MES technically and functionally as the primary local IT expert, through implementation and ongoing production support.
- Support the full MES solution: requirements, design, configuration, integration, testing, validation, deployment, troubleshooting, and continuous improvement.
- Turn complex manufacturing and business requirements into technical solutions that scale and are easy to support.
- Design, support, and troubleshoot integrations between MES, automated production equipment, ASRS and material-handling systems, databases, and other manufacturing applications, using tools such as REST APIs, OPC UA, RabbitMQ, Windows Services, and SQL Server.
- Write and troubleshoot SQL queries, stored procedures, data interfaces, and reports, including SSRS.
- Investigate production issues across multiple systems, find root causes, and coordinate fixes with the right teams to keep downtime to a minimum.
- Take part in system integration testing, validation, deployment, change control, and documentation in a regulated medical-device environment.
- Create and maintain technical documentation, interface specs, support procedures, troubleshooting guides, and knowledge-transfer materials.
- Find ways to improve system reliability, monitoring, supportability, automation, and manufacturing process efficiency.
- Give technical guidance and escalation support to the local IT support team on MES and manufacturing system issues.
What we’re looking to add to our team:
- Bachelor’s degree in Information Technology, Computer Science, Engineering, Information Systems, or a related field, or equivalent professional experience.
- Typically requires 6–8 years of experience supporting enterprise, manufacturing, MES, or integrated business systems.
- Strong experience with MES and manufacturing system integrations.
- Strong SQL Server and SQL skills, including troubleshooting queries, stored procedures, data flows, and application and database issues.
- Experience with integration technologies such as REST APIs, OPC UA, RabbitMQ or similar messaging tools, and Windows Services.
- 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 across IT, Engineering, Automation, Manufacturing Operations, Quality, vendors, and corporate teams.
- Experience in a regulated medical-device manufacturing environment is highly desirable, including system validation, change control, documentation, and compliance.
- Experience supporting systems connected to manufacturing automation, production equipment, material-handling systems, or ASRS is highly desirable.
- Experience with Apache NiFi or a similar data integration platform is preferred.
- Experience with SSRS or similar reporting tools is preferred.
What you'll receive for the great work you provide:
- Full range of medical, dental, and vision plans
- Life Insurance
- Short-term and Long-term Disability
