About Siemens Processing Systems Engineering

Siemens Process Systems Engineering Limited (SPSE) is a software development company delivering leading Advanced Process Modelling software (the gPROMS platform) and related model-based engineering and services to the process industries.

We work with all the major process industry sectors including chemicals and petrochemicals, oil and gas, pharmaceutical, life sciences, food, power and many more. Not sure what a process industry is?  It is an industry that is concerned with the processing of bulk resources or materials and turning them into other products. Think about how your toothpaste or pain relief medication is made.  It also involves managing resources like power, wastewater and carbon capture.

Our customers comprise many of the largest companies in the world. Some of them you will have heard of, others you may have heard of or used their brands.

SPSE’s software products and services help our customers improve their processes and product designs, enhance their operations, and be more efficient and effective during the R&D phase. For example, our software is being used in the design and development of Fuel Cell technology, the next big thing in electric vehicles.

The role

We are now looking for a highly motivated C++ Software Developer, with particular focus on advanced numerical and symbolic computation applied to the solution and optimization of large systems of nonlinear equations. You will be part of an international, friendly and supportive development team, designing and implementing new functionality and influencing the future architecture of a state-of-art mathematical modelling environment.
