Our client is seeking a skilled Senior Operational Research Scientist with deep expertise in optimization modeling and production-grade decision-support systems to join their growing team. You will play a key role in designing, deploying, and scaling advanced optimization solutions that solve complex business challenges while partnering with cross-functional stakeholders to drive measurable business outcomes. Your work will directly impact operational efficiency, strategic decision-making, and long-term business growth.

Key Responsibilities

• Design, develop, and optimize advanced Operations Research models using Linear Programming (LP), Mixed Integer Programming (MIP), heuristics, metaheuristics, decomposition techniques, and stochastic or robust optimization methods.
• Lead the architecture and implementation of scalable optimization pipelines, ensuring maintainability, performance, and seamless integration with enterprise applications.
• Collaborate with business stakeholders to translate operational challenges, constraints, and objectives into optimization models and measurable KPIs.
• Identify technical bottlenecks and organizational process improvements, recommending practical optimization strategies that maximize business value and ROI.
• Mentor junior Operations Research Scientists through technical reviews, coaching, and knowledge sharing while promoting engineering best practices.
• Drive technical roadmap planning, technology evaluation, and solution design, balancing long-term architecture with short-term business priorities.
• Establish model validation, monitoring, data governance, and quality assurance processes to ensure reliable, transparent, and production-ready optimization solutions.

Must-Have Qualifications

• MS or PhD in Operations Research, Applied Mathematics, Industrial Engineering, Computer Science, or a related quantitative field.
• 5+ years of professional experience designing, deploying, and maintaining Operations Research solutions in production environments.
• Deep expertise in optimization techniques including heuristics, metaheuristics, Benders Decomposition, Column Generation, Lagrangian Relaxation, and hybrid optimization approaches.
• Strong programming skills in Python or C++ with hands-on experience using optimization tools such as Gurobi, CPLEX, and Pyomo.
• Experience integrating optimization models with enterprise systems, APIs, distributed computing environments, and modern data engineering pipelines.
• Proven ability to deliver optimization solutions with measurable improvements in operational efficiency, service levels, revenue, or cost reduction.
• Excellent communication skills with the ability to explain assumptions, trade-offs, and technical concepts to both technical and non-technical stakeholders while leading cross-functional initiatives.

Preferred Qualifications

• Experience delivering optimization solutions across multiple industries and business domains.
• Background in building scalable, cloud-based optimization platforms and production ML/OR pipelines.
• Experience defining optimization strategy and influencing technical roadmaps within growing organizations.
• Passion for mentoring technical teams and fostering a collaborative engineering culture.
• Strong business acumen with a practical, ROI-focused approach to solving complex operational problems.
