· Carry out feedstock assessment, biogas yield calculations, organic loading, hydraulic retention time, digester sizing, and mass/energy balances.

· Develop and review PFDs, P&IDs;, process calculations, equipment specifications, and process datasheets.

· Optimize digester configuration, mixing systems, feeding systems, gas handling, and downstream processes.

· Provide technical inputs for plant performance guarantees and commissioning requirements.

2. Engineering Management

· Lead multidisciplinary engineering activities covering process, mechanical, piping, electrical, instrumentation, and civil interfaces.

· Review engineering drawings, layouts, equipment specifications, and vendor documents.

· Coordinate with internal engineering teams, consultants, vendors, EPC partners, and customers.

· Ensure engineering deliverables are completed within project timelines and agreed technical requirements.

3. Technical & Commercial Proposals

· Lead preparation of technical proposals for CBG projects.

· Define technical scope, battery limits,



equipment requirements, exclusions, and assumptions.

· Work closely with the commercial team to develop accurate project costing and commercial offers.

· Review customer RFQs, tender documents, specifications, and technical requirements.

· Participate in technical discussions and negotiations with customers and EPC partners.

4. Project & Execution Support

· Provide engineering support during procurement, fabrication, construction, installation, commissioning, and operation.

· Resolve technical issues arising during project execution.

· Review site requirements and support project teams with engineering decisions.

· Participate in commissioning and performance evaluation of CBG plants.

· Analyze plant operating data and recommend process improvements where required.

5. Technology & Process Development

· Continuously evaluate improvements in anaerobic digestion and CBG technologies.

· Develop standardized engineering practices, design parameters, calculation methods, and technical documentation.

· Maintain project learnings and incorporate operational experience into future plant designs.

· Support development of solutions for multi-feedstock CBG plants.

Required Qualifications

· Bachelor's or Master's degree in Chemical Engineering, Biotechnology, Environmental Engineering, Mechanical Engineering, or a related discipline .

· Typically 8–15 years of relevant experience in biogas, CBG,



anaerobic digestion, waste-to-energy, process engineering, or related industries.

· Strong practical understanding of anaerobic digestion and CBG plant design.

· Experience with engineering documentation such as PFDs, P&IDs;, equipment datasheets, layouts, and process calculations.
