Senior Operations Research Scientist

About the Role

Join Just Eat Takeaway.com as a Senior Operations Research Scientist and be instrumental in creating an optimisation framework that efficiently allocates supply and demand within our logistics network. This role involves working with extensive geospatial and live data streams to develop decision-making automation suited for complex, real-time scenarios.

Your Responsibilities

• Create robust, high-performance optimisation models using various advanced techniques including mixed-integer programming, constraint programming, stochastic programming, and metaheuristics, deploying them at scale for operational decision-making.
• Design and implement large-scale scheduling, rostering, or shift-planning optimisation systems for live production environments.
• Develop and maintain optimisation models with a focus on scalability and long-term operational effectiveness.
• Apply software engineering best practices such as testing, CI/CD, and version control in your modelling and delivery process.
• Collaborate across teams, serving as a mentor to junior scientists and bridging gaps among data science, engineering, and business teams.

Qualifications and Skills

• Proven expertise in exact optimisation methods, especially mixed-integer programming and decomposition strategies, coupled with heuristic approaches for handling scaling challenges.
• Extensive experience in Python programming with strong object-oriented design, familiarity with algebraic modelling languages or solver APIs (like Pyomo, PuLP), and optimisation solvers (e.g., SCIP, Gurobi).
• Background in deploying optimisation models into production environments and maintaining them effectively over time.
• Knowledge of Docker containerization for reproducible and scalable computing environments.
• Prior work experience in logistics or last-mile delivery sectors is advantageous.

Personal Attributes

• Ability to manage complex operational restrictions, including contractual and geographical considerations over time.
• Innovative thinking to test hypotheses rigorously and propose business improvements.
• Strong communication skills to clearly explain complex optimisation concepts to both technical and non-technical stakeholders.
• Preference toward simple, scalable solutions in complex systems.
• Comfort working in agile, collaborative settings to ensure synergistic teamwork.
