Job description

Job Purpose

The Senior Engineer will lead the development and deployment of AI-driven closed-loop injection process control to roll out our projects, focusing on plastic gear manufacturing and water pump component capability improvement. This role is accountable for establishing the end-to-end (E2E) injection process data application framework and educating the team to embed data-driven practices into daily work. Additionally, the role will upskill the team's technical competencies across modern AI/software tools, bridging the gap between manufacturing process knowledge and digital transformation.

Key Responsibilities

1. Injection Process AI & Closed-Loop Setup

• Lead the design, development, and deployment of AI-based closed-loop process control for injection molding machines.

• Drive the project rollout for plastic gear and water pump component application, ensuring measurable improvements in capability (Cp/Cpk) and defect reduction.

• Integrate real-time process signals, sensor data, and quality feedback to build self-optimizing process loops.

• Collaborate with tooling, quality, and production teams to validate AI models on production lines.

2. E2E Injection Process Data Application & JEB Enablement

• Architect and implement an end-to-end data pipeline for injection molding process data — from machine/sensor acquisition through storage, analysis, visualization, and decision support.

• Build dashboards and reporting tools to visualize process performance, OEE, capability trends, and AI model outputs.

• Educate and mentor the JEB team (process engineers, technicians, operators) on how to interpret and act on data in their daily work — shifting from instinct-driven to data-driven decision making.

• Create standard operating procedures (SOPs), training materials, and hands-on workshops for sustaining the data culture.

3. Team Capability Building (Software & AI Skills)

• Drive technical upskilling of the engineering team across the following software and AI tool stack:

  • Python – for data analysis, scripting, automation, and ML model development.

  • SQL – for querying manufacturing databases, process historians, and MES systems.

  • LLM / RAG (Large Language Models & Retrieval-Augmented Generation) – for building knowledge assistants, troubleshooting guides, and document intelligence tools.

  • Azure AI Studio – for developing, deploying, and managing AI models in the cloud.

  • Power BI – for creating interactive process dashboards and real-time visual analytics.

  • Manufacturing Process Knowledge – deep understanding of injection molding, material science, and process optimization.

• Lead at least 1–2 full-cycle AI project deployments into production, managing the end-to-end lifecycle from problem definition, data collection, model training, validation, deployment, and monitoring.

4. Cross-Functional Collaboration & Innovation

• Partner with IT, Data Engineering, and OT (Operational Technology) teams to ensure seamless data connectivity between shop floor systems and cloud/analytics platforms.

• Identify new opportunities for AI/ML application in manufacturing (e.g., predictive maintenance, defect classification, yield optimization).

• Stay current with emerging trends in AI for manufacturing and introduce relevant innovations to the organization.

• Document project outcomes, best practices, and lessons learned for organizational knowledge retention.

Required Qualifications & Skills

Education

• Bachelor's degree or higher in Mechanical Engineering, Manufacturing Engineering, Computer Science, Data Science, Electrical Engineering, or a related technical field.

Experience

• Hands-on experience with injection molding machines, process parameters, tooling, and material science (especially plastic gears and/or pump components).

• Proven track record of deploying at least 1–2 AI/ML projects into production environments in a manufacturing context.

• Experience with closed-loop process control systems is highly preferred.
