MES Systems Engineer

We are looking for a MES Systems Engineer / Manufacturing Execution System Systems Engineer to join a collaborative manufacturing environment in Torrance, California. This Long-term Contract position will focus on improving manufacturing system performance, supporting application enhancements, and helping teams use system tools effectively across production and engineering functions. The role works closely with partners in production, design engineering, quality, and supply chain to strengthen data accuracy, streamline processes, and support reliable day-to-day operations.

Responsibilities:

• Partner with cross-functional stakeholders to maintain accurate system records and ensure manufacturing data is configured correctly for operational use.

• Assist with application enhancements and tailored system functionality that align with production and engineering requirements.

• Support connections between manufacturing platforms and related business systems, including enterprise and product lifecycle tools.

• Create and organize user guidance and training materials to improve adoption among engineering and manufacturing teams.

• Investigate system issues, resolve technical problems efficiently, and minimize disruption to manufacturing activities.

• Coordinate software testing, validation, and rollout activities to confirm new functions perform as expected before release.

• Contribute to structured change and release control practices for the manufacturing application and its connected systems.

• Identify system gaps and recommend practical solutions that improve usability, reliability, and process efficiency.

• Provide additional support for manufacturing process development and other advanced manufacturing initiatives as needed.

Industry & Environment

• Manufacturing experience is required.
• Siemens Opcenter experience is required.
• Candidate should be comfortable working on a manufacturing floor and engaging directly with operations teams.

• Application support experience within manufacturing systems environments

What Will Make Someone Successful

• Previous experience supporting software systems on a manufacturing floor.
• Comfortable working in a dynamic environment where priorities shift daily.
• Self-starter who is not afraid to ask questions and gather information from stakeholders.
• Strong communication skills with both US and UK-based teams.
• Ability to adapt quickly to evolving processes and system requirements.

Biggest Challenges

• Supporting a relatively new Siemens Opcenter implementation.
• Helping users adjust to new system rules and processes.
• Maintaining and improving manufacturing data quality.
• Managing ongoing system changes while supporting day-to-day production needs.

What's in it for you?
