Job summary

Fidelity Investments seeks a Director of Engineering for WFM Operations Research to lead the development of a modern, in‑house Workforce Management optimization platform. You will own the constraint model, design the schedule engine with OR‑Tools/CP‑SAT, and deliver a scalable solver within the production WFM stack.

You will collaborate with architects and teams to ensure accurate, actionable schedules and measurable quality metrics while guiding a senior team through complex optimization

Qualifications

• Bachelor’s or 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.

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.
