Job Description:

Note: Fidelity will not provide immigration sponsorship for this position.

The Role

Fidelity is building a modern, in-house Workforce Management (WFM) platform. You will own and build a constraint-solver foundation for the Contact Center Workforce Management schedule optimization engine leveraging a CP-SAT/OR-Tools engine at enterprise scale and reliability. This role is deeply a hands‑on role, you will design, develop, and implement advance optimization models and algorithms to solve complex workforce planning and scheduling problems.

Key Responsibilities

• Research, design, and develop optimization models for contact center workforce planning, scheduling and resource allocation.
• Design and implement the schedule 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 solver as a service within the WFM platform that meets latency targets for real forecast group volumes
• Define 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 tests and validation of optimization algorithms to deliver performance, scalability, and accuracy
• Collaborate 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 results to engineering and business stakeholders.
• Partner with workforce‑planning and real‑time‑analyst stakeholders to validate that generated schedules are operationally usable.

Required Qualifications

• Bachelor’s of master’s degree in operations research, Mathematics, Computer Science, or a related field.
• 5+ years of experience in applying operations research techniques to real‑world problems
• Hands‑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 in Java, 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 and event‑driven architecture

Preferred Qualifications

• Prior experience building scheduling or optimization capability at a WFM SaaS provider or a large in‑house contact center operations team.
• Familiarity with other solver technologies (e.g., Gurobi, CPLEX, OptaPlanner).
• Experience in applying ML, AI, or Data Science

Fidelity’s Onsite Working Model
Fidelity 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.
