Routing Engineer (C++/Java/Rust) 80% - 100%

You will be the architect of our map's intelligence, building the brain that powers our next-generation navigation experience.

We aren't just finding the shortest path; we're creating a deeply personalised, multi-modal, and predictive routing engine from the ground up.

This is a unique opportunity to solve complex algorithmic challenges and build a system that learns from every journey, powered by cutting-edge research and high-performance code.

What you'll be doing

• Designing and building a highly customisable engine, with the choice to extend an existing open-source project (like OTP, Graphhopper, Valhalla) or build our own to meet unique product needs.
• Designing clean, scalable routing APIs and collaborating with backend and mobile engineers to ensure they are robust and easy to use.
• Contributing across the stack by applying your engineering skills to our backend services or geospatial data processing pipelines.
• Creating the foundation for our AI-powered personalisation, where edge weights (speed, cost, preference) are dynamically adjusted for each user.
• Implementing complex multi-modal routing logic that can seamlessly combine walking, public transport, and ride-sharing into a single, optimised journey.
• Over time solving for modern transport challenges, such as building Electric Vehicle (EV) routing that intelligently incorporates charging stops, battery levels, and station availability.
• Developing and optimising core routing algorithms like A\, Contraction Hierarchies (CH), or other speed-up techniques for continental-scale networks.

Building the testing and verification harness that keeps routing correct such as golden-route regression suites, invariant checks (e. g. triangle inequality, symmetry where expected), and benchmarks that catch performance regressions as the graph and algorithms evolve.

Requirements

• A portfolio or Git Hub profile showcasing strong projects in algorithms, data structures, or systems programming.
• Deep proficiency in a high-performance language, specifically C , Java or Rust.
• Proven experience implementing and working with graph algorithms, particularly for routing (e. g., Dijkstra, A\, CH, Isochrones).
• Familiarity with the challenges of routing on real-world data like Open Street Map (OSM).
• Experience in API design and a solid understanding of how to build scalable, low-latency web services.
• A \"T-shaped\" or \"tree-shaped\" mentality, with a genuine interest in contributing to different parts of the product.
• 3 years experience in a professional environment with a demonstrable record of shipping production software
• A rigorous approach to correctness and testing, with experience verifying algorithmic output where the \"right answer\" is non-trivial (e. g. regression testing, property-based testing, or validating against a reference implementation).

What you can expect

• A collaborative and supportive team with short decision-making paths.
• Exciting and meaningful projects using modern technologies.
• The opportunity to contribute your ideas and take ownership of your work.
• Competitive compensation and opportunities for professional growth.
• A culture that values learning, knowledge sharing, and continuous improvement. Grow with a young, ambitious company that values innovation, initiative, and ownership.

If you have any questions, please do not hesitate to contact Ms Manuela Unger, Head of Human Resources.
