Senior Optimization Developer (C++ & CPLEX) :: Remote

Position : Senior Optimization Developer (C++ & CPLEX)

Location : Remote but needs to be in Chicago 4 times a month - locals only but sell as remote

Duration : 6 months w/ possible extension

Interview : Video

Process:

• 45-60 minute video interview with Plamen + modelers on the team
• Potential 2nd round if they have multiple candidates they re picking between
• We are looking for someone with good experience with modeling
• IBM ILOG CPLEX is a MUST
• C++ -- hard requirement

Project Name: - Network Planning Schedule Design Optimizer

Then the stack. Every requirement is a filter, and they multiply: CPLEX model-building (he explicitly excluded model-support people), production C++, 4+ years applied OR, 3+ years large-scale mixed-integer and nonlinear work, OR education in practice if not on paper, transportation domain preferred. Then contract, not perm, at six months, with Chicago onsite. People who clear that intersection are employed and are not scanning job boards.
