Senior Product Engineer, IMS

We're looking for an experienced Senior Product Engineer to own and evolve our core systems end-to-end. You'll join our engineering team and work closely with product, operations, and data stakeholders across the business. Your work will power high-scale systems used by both internal operators and external users, directly impacting large volumes of real-world activity.

What you'll do

• Build a customer-facing transit schedule system that handles hundreds of thousands of bus departures daily. The system serves hundreds of thousands of travellers and is used by hundreds of operators, including operations teams, revenue managers, and planners.
• Build a ticket booking backend that allocates bus seats to travellers. Design smart allocation strategies to maximise seat usage across stops, and handle complex reallocation scenarios such as vehicle swaps, bus merges, and reinforcements.
• Build a revenue management system that dynamically prices seats based on time to departure, demand, and remaining capacity. Support carrier-controlled pricing, A/B testing, and automated pricing algorithms.
• Own and evolve the data transformation layer that powers schedules, bookings, and revenue. Design robust models, incremental pipelines, and clear semantic definitions grounded in real operational data.
• Raise data quality through strong testing, contracts, freshness checks, and monitoring so issues are detected automatically, not by stakeholders.
• Partner with stakeholders across operations, planning, and revenue. Turn ambiguous problems into clear requirements, challenge assumptions, and align solutions with real-world constraints.

What you'll need

• Several years of experience building and operating backend services in Python, with ownership across the full lifecycle: design, implementation, deployment, monitoring, and maintenance.
• Demonstrated an ownership mindset with the ability to independently drive projects, manage competing priorities, and contribute effectively across multiple systems and initiatives.
• Strong understanding of distributed systems and data-intensive applications. Experience designing systems that handle large volumes of data and traffic, with practical knowledge of consistency models, state machines, asynchronous workflows, and event-driven architectures.
• Deep database expertise: transaction management, ACID guarantees, indexing strategies, query optimisation, locking, partitioning, and sharding. You understand how database design impacts system performance and reliability at scale.
• Experience building reliable distributed systems using patterns such as outbox, idempotency, retries, and eventual consistency.
• Product-minded engineer who contributes beyond implementation. You actively shape technical direction, influence product decisions, and help define the future evolution of the platform.

Nice to have

• Experience with cloud infrastructure, messaging systems, distributed databases, and high-availability architectures.

What they offer

• Make a global impact helping millions of people discover and book ground transportation worldwide.
• Take responsibility from day one and see the direct impact of your contributions.
• Work with modern, efficient solutions and a tech stack that evolves continuously.
• Partner with industry leaders including Booking.com, Google Maps, Amtrak, Deutsche Bahn, Renfe, and SNCF.
• Flexible and remote-friendly working options with relocation opportunities.
