Buckman is a privately held, global specialty chemical company with headquarters in Memphis, TN, USA, committed to safeguarding the environment, maintaining safety in the workplace, and promoting sustainable development. Buckman works proactively and collaboratively with its worldwide customers in pulp and paper, leather, and water treatment to deliver exceptional service and innovative specialty chemical solutions to help boost productivity, reduce risk, improve product quality, and provide a measurable return on investment.  Buckman is in the middle of a digital transformation of its businesses and focused on building the capabilities and tools in support of this.


Buckman is seeking an experienced Chemical process modelling engineer to be part of the development of the Modelling COE at our Chennai facility. Reporting to the Digital Innovation Manager, the Modelling engineer will be responsible for developing mathematical models of chemical processes for real-time parameter estimation and process optimization. The Modelling Engineer will also be responsible for developing physics-based models of assets commonly used in chemical processing in order to simulate various process operational scenarios.  

You will work closely with Buckman stakeholders to derive deep industry knowledge across paper, water, leather, and performance chemical industries.  You will help develop the modelling center of excellence strategy for the company including creation of the project portfolio, partnering with external providers, and augmenting capabilities with internal hires.  A large part of the job is communicating and developing relationship with key stakeholders and subject matter experts to tee up proofs of concept projects. You will not have a large internal team to rely on, at least initially, so individual expertise, breadth of modelling and simulation competency, and ability to partner with external companies will be essential for success. 

You will be working closely with a multi-disciplinary team consisting of subject matter experts, R&D, sales, and Digital associates, and marketers, in the development, and deployment of Process modelling solutions.  If you like working for an entrepreneurial company with a sustainability mission and digital ambitions at the core of its strategy, Buckman is the place for you.
