Your key responsibilities

• Develop and maintain core optimisation logic using C++ and AMPL.
• Integrate and optimise solver engines (Gurobi, AMPL Solver, Maroma).
• Build and enhance desktop UI workflows for scenario modelling and analysis.
• Implement APIs and integrations with external tools and data sources.
• Support batch execution, automation, and performance tuning.
• Contribute to source control, builds, and regression testing.
• Work on large-scale optimisation problems involving millions of decision variables and constraints.
• Contribute to performance improvements and solver efficiency.
