  • Cloud Development (Azure): Working knowledge of Microsoft Azure services, including application hosting, data services, and cloud-native solution design
  • Data Engineering Fundamentals: Experience working with relational databases such as Azure SQL, including query optimization and data modeling concepts
  • DevOps & CI/CD: Understanding of source control, build/release pipelines, and automated deployment practices
  • System Integration: Experience integrating applications with external systems, including OT/IoT or enterprise platforms
  • Collaboration & Communication: Ability to work effectively within cross-functional teams and communicate technical concepts clearly to both technical and business stakeholders

Preferred Skills
  • Education/Experience: Bachelor's degree in Computer Science, Engineering, or related field, or relevant industry experience.
  • Experience in manufacturing environments or industrial systems.
  • Familiarity with MES/MESA frameworks, ERP systems, or shop floor data systems
  • Experience working with large-scale, high-frequency data processing systems
