• Work across MES data models, including master data, bills of materials, routing and material tracking.
• Support integrations between manufacturing equipment, MES and enterprise systems using OPC, MQTT, REST and ERP connectors.

Architecture and technical oversight

• Define and enforce coding standards, architectural principles and design patterns across all delivery teams.
• Review and validate architecture proposals from Senior Leads.
• Own final code approval before changes reach production.
• Establish estimation methods and review estimates provided by technical leads.
• Improve component reuse and reduce technical debt across the programme.
• Support Senior Leads with complex technical decisions and competing requirements.
• Mentor technical leads and develop their architectural thinking.
• Onboard new team members onto technical standards, processes and ways of working.

• Strong understanding of MES data modelling, including master data, bills of materials, routing and material tracking.
• Experience defining coding standards, conducting code reviews and enforcing quality gates.
• Working proficiency in frontend development using the CM GUI framework or an equivalent.
• Working knowledge of IoT and integration architecture, including OPC, MQTT, REST and ERP connectors.
• Experience overseeing or coordinating technical work across multiple teams.
• Fluent written and spoken English.
