ICONMA, LLC • United States, United States • Posted July 22, 2026
Position Overview
Our Client, an IT Services and Consultant company, is looking for a Senior Operations Research (OR) Scientist – Mathematical Optimization (MIP) for their Dallas, TX location. Responsibilities:
+ Works on the mathematical optimization model at the heart of a task assignment model adhering to some complex work rules
+ Formulate and maintain the MIP
+ Translate real business rules into formulation with planners
+ Drive the model through the FICO Xpress Java API, generate/inspect .lp files and solver logs.
+ Tune the solver; mip-gap, mip-abs-gap, threads, random seed, determinism; reason about branch-and-bound performance and runtime.
+ Keep the model solver-agnostic behind the LinearExpression / LinearConstraint / Sense / Sign abstraction so it stays testable and portable.
+ Validate & benchmark solutions
+ Analyze data stored in Azure ADLS to debug the model and find issues; mine input/output dataset...
