About the Role
As a Senior Operations Research Scientist, you will lead the design, development, and deployment of mission-critical optimization models, simulation tools, and decision-support solutions to aid key operational decisions across the airline. You will combine deep technical expertise with strong stakeholder engagement to solve complex operational challenges, influence strategic decisions, and deliver measurable business impact.
Responsibilities
- Lead the architecture and delivery of advanced operations research solutions across crew planning, aircraft scheduling, network resilience, and ground operations.
- Design and implement high-performance optimization algorithms and production-grade solutions using Python, C++, and commercial optimization solvers.
- Integrate optimization, simulation, and reinforcement learning techniques to solve complex multi-stage decision problems.
- Partner with senior stakeholders to translate business challenges into mathematical models with clear operational and commercial outcomes.
- Lead delivery across the full data science and optimization lifecycle, from opportunity identification through to deployment and continuous improvement.
- Collaborate with data and technology teams to ensure data quality and availability for optimization solutions.
- Mentor colleagues in operations research techniques, conduct technical reviews, and help establish best practices across the organization.
- Represent easyJet through industry events, academic partnerships, and engagement with the wider optimization community.
Requirements
- Expert knowledge of operations research, mathematical programming, simulation methodologies, stochastic processes, and decision theory.
- Advanced programming skills in Python and C++, or similar high-performance languages.
- Strong experience using optimization software such as Gurobi, CPLEX, or Xpress.
- Proven track record of delivering operations research and optimization solutions within operational environments.
- Experience solving large-scale routing, scheduling, or resource allocation problems within aviation, transport, logistics, supply chain, or other complex network-based environments.
- Strong understanding of algorithm design, computational complexity, and performance optimization techniques, including heuristics and metaheuristics.
- Excellent communication and influencing skills with the ability to explain sophisticated mathematical concepts to a range of audiences.
- Demonstrated leadership capability and experience working across cross-functional teams.
- Significant relevant industry experience within operations research and optimization, with evidence of technical leadership progression.
- Cloud-based optimization platforms and distributed computing (desirable).
- Machine learning and hybrid optimization approaches (desirable).
- Simulation, reinforcement learning, and advanced heuristic methods (desirable).
- Commercial airline operations, crew planning systems, or aircraft scheduling (desirable).
- Aviation regulations and operational constraints (desirable).
