• Develop and improve internal tools for process design and equipment sizing.
• Design and execute experiments, including building and operating bench-scale and pilot-scale systems for proof-of-concept, design verification, and validation.
• Lead pilot system design, setup, commissioning, and troubleshooting activities.
• Conduct technical risk assessments (e.g., HAZOP), including identification of failure modes, mitigations, and control strategies.
• Develop control philosophy and functional narratives in collaboration with PLC programmers to ensure robust system automation.
• Coordinate engineering inputs required for GA drawings, 2D layouts, and 3D models.
• Ensure technical deliverables are accurate, consistent, and aligned with validated performance data.
• Work closely with Engineering and Manufacturing teams to translate R&D outputs into standardized, repeatable, and manufacturable design packages.
• Establish commissioning and acceptance protocols, troubleshooting playbooks, and field readiness standards.
• Support on-site commissioning and pilot studies as required.
• Capture field learnings and translate them into design improvements, tool enhancements, and updated engineering standards.
• Collaborate with commercial teams to incorporate feedback from operating projects into design improvements.
• Execute NPI plans, including scope definition, milestones, and resource planning.
• Support proposal and regional manufacturing teams in conducting costing exercise, drafting budgetary and technical proposal for solution packages offering
