Fidelity will not provide immigration sponsorship for this position.Job Description:The RoleFidelity is building a modern, in-house Workforce Management (WFM) platform.You will own and builda constraint-solver foundationfor the Contact Center Workforce Management schedule optimization engineleveraging a CP-SAT/OR-Tools engineatenterprise scale and reliability.This roleis deeply a hands-on role,you willdesign, develop, and implement advance optimization models and algorithms to solve complex workforce planning and scheduling problems. Key ResponsibilitiesResearch, design, and develop optimization models for contact center workforce planning, scheduling and resourceallocation.Design and implementtheschedule optimization engine using OR-Tools/CP-SAT Own the constraint model end to end: formalize business rule into a solvable, maintainable model.Build the production-grade solveras a service within the WFM platform that meets latency targets forrealforecast group volumesDefine and validate schedule quality metrics (coverage attainment, constraint violations, solve time, solution stability across re-solves) and instrument the service so quality can be monitored in production.Build and execute testsand validation of optimization algorithms to deliver performance, scalability, and accuracyCollaborate with architects and engineering teams to integrate optimization models into an enterprise-grade optimization engine of the workforce management platform.Effectively communicate and present findings, methodologies, and resultsto engineering and business stakeholders.Partner with workforce-planning and real-time-analyst stakeholders to validate that generated schedules are operationally usable.Required QualificationsBachelor’sofmaster’s degree in operations research, Mathematics, Computer Science, or a related field.5+ years of experience in applying operations research techniques to real-world problemsHands-on production experience with OR-Tools, CP-SAT, or a comparable constraint-programming / mixed-integer-programming solver.Strong foundation in linear programming, integer programming, or stochastic optimization.Proficiency inJava, Python, or C++.Experience with cloud platforms such as AWS, GCP, or Azure.Experience working with large datasets and solving large scale optimization problems.Direct experience modeling and solving workforce or resource scheduling problems. Working knowledge of WFM domain.Knowledge of distributed systems andevent-driven architecturePreferred QualificationsPrior experience building scheduling or optimization capability at a WFMSaaS provideror a large in-house contact center operations team.Familiarity with other solver technologies (e.g.,Gurobi, CPLEX,OptaPlanner).Experienceinapplying ML, AI, or Data ScienceFidelity’s Onsite Working ModelFidelity is transitioning to a full-time onsite working model through a phased rollout across regions and roles. Currently, some roles and locations require 100% onsite presence, while others require less. Onsite expectations are likely to evolve as the rollout continues. This transition does not apply to fully remote roles.Certifications:Category:Information TechnologyPlease be advised that Fidelity’s business is governed by the provisions of the Securities Exchange Act of 1934, the Investment Advisers Act of 1940, the Investment Company Act of 1940, ERISA, numerous state laws governing securities, investment and retirement-related financial activities and the rules and regulations of numerous self-regulatory organizations, including FINRA, among others.
