Journey Planning Developer

We enable people to move easily and safely around our world. Zipabout is designing the future of transport where each journey is personalised. We partner with transport leaders, government and event organisations to provide a better, safer personalised journey experience for all.

Multi-modal routing and real-time transport data are at the heart of everything we do, and we use a wide range of open-source and proprietary systems to power our unique real-time messaging platform for transport operators. We are looking for a talented individual to join our leading‑edge team of engineers and developers, focusing on the customisation and extension of our core multi-modal routing platform (Open Trip Planner ).

• Work closely with the tech director and senior developers to extend and customise our OTP-based multi-modal routing platform.
• Liaise with the product team to identify and specify existing and future functionality for the core routing platform, and coordinate with the OTP community to align development with the wider project roadmap.
• Develop unit and integration tests and help create complex systems to validate and improve data and routing quality.
• Contribute to clear documentation of new processes and improvements to existing documentation.

• Prior experience working with Open Trip Planner  (OTP) or a similar open/closed‑source multi-modal routing engine.
• Familiarity with data standards such as GTFS, SIRI, NeTEx, Trans Xchange, etc.
• Solid knowledge of Java; experience with Scala is also useful.
• Experience with source control (Git preferred), continuous integration, and unit/integration testing and issue management software (Jira ideally).
• Bash scripting and basic Unix deployment and configuration experience.

• Experience with ETL / stream processing.
• Familiarity with both relational and No
  
  SQL databases (e.g. MySQL or DynamoDB).
• Commercial experience with Amazon Web Services (Lambda, API Gateway, Kinesis, DynamoDB, S3, EC2, ECS, etc.).
• Familiarity with RESTful API design concepts.
