Job description

Via is on a mission to create public transportation systems that provide far greater access to jobs, healthcare, and education. Our platform serves as the technology backbone for modern transit networks, transforming antiquated and siloed public transportation systems into smart, data-driven, and efficient digital networks. With hundreds of agency partners around the world, Via is recognized as the leading transportation technology and service provider globally.
As an Algorithm Researcher at Via, you'll join our R&D team in London as part of the core Algo group, which is responsible for developing and maintaining Via’s proprietary algorithms that run in production on our live servers. The role sits at the intersection of algorithm development, data science, and software engineering. You'll work on complex algorithmic problems, explore and evaluate different approaches, and turn your solutions into reliable production systems that support Via’s transportation networks around the world. If you enjoy combining analytical thinking, algorithms, data, and hands‑on development, this position might be just for you!

What You'll Do:

• Design, develop, and improve Via’s core algorithms and business logic, solving complex real-world problems.
• Explore and evaluate algorithmic approaches using data, experimentation, and analytical methods.
• Develop and maintain mission-critical services that bring algorithmic solutions into production.
• Work with large datasets to analyze system behavior and improve the performance of our algorithms.
• Take ownership of complex technical problems, from initial research and exploration through to production.
• Work in close collaboration with algorithm developers, researchers, data scientists, and software engineers.

Who You Are:

• M.Sc. or Ph.D. in Computer Science / Mathematics / Statistics / Operations Research / similar quantitative field.
• 3+ years of relevant industry experience in algorithm development, data science, research, or software engineering with a strong algorithmic focus.
• Strong knowledge of algorithms, data structures, and analytical problem-solving.
• Strong Python skills and experience developing production-quality code.
• Experience working with data and applying data science, optimization, or analytical techniques to solve complex problems.
• Experience taking algorithms, models, or prototypes and turning them into production systems.
