About Us:

RATP Dev is a subsidiary of the RATP Group, a global leader in high-capacity urban rail and the world’s third largest public transport operator.

We build, deliver and commit to the best of public transport - every day, everywhere, for everybody- making it the natural choice for cities and passengers.

We are currently seeking an experienced Senior Data Engineer to join TransitLinX (a John Holland and RATP Dev Joint Venture) based in Melbourne on the Suburban Rail Loop project. 

About the Role:

The Senior Data Engineer plays a key role in delivering a strategic Enterprise Data Platform as a core pillar of TransitLinX’s digital transformation. Supporting both the Construction and future Operations phases of the project, you will be instrumental in operating and evolving our newly built Data Lake, supporting business data consumers, and establishing Data Governance foundations.

Reporting to the Enterprise Systems & Innovation Manager, this role offers a strong growth opportunity for a hands-on technical professional who wants to contribute to building a Data Lake from the ground up within a structured, international, and high-impact environment. In this role, you will:

• Design, develop, and maintain data ingestion and transformation pipelines on AWS and Snowflake
• Implement and operate staging, clean, and datamart data layers
• Ensure data quality, reliability, and traceability through validation, monitoring, and controls
• Provide day-to-day operational support and maintenance of the Data Platform
• Act as a technical point of contact for Data Lake users across BI, reporting, analytics, and project teams
• Analyse business requirements and deliver robust, scalable data solutions
• Publish and maintain curated datasets, views, and data models to support multiple business domains
• Contribute to the Data Architecture vision and its ongoing evolution
• Integrate the Data Lake with broader enterprise systems (asset management, maintenance, ticketing, and external platforms)
• Review and challenge technical solutions proposed by system integrators and vendors
• Contribute to the progressive implementation of Data Governance foundations, including data quality standards, security principles, and documentation lineage
• Work closely with TransitLinX partners and RATP Dev HQ in France to align with corporate standards and best practices

About You:

You are an autonomous, structured, and delivery-focused data professional with a strong architecture mindset. You have the ability to take a step back to assess solutions, while remaining comfortable interacting with both technical and non-technical stakeholders. You are driven by the opportunity to build, structure, and evolve a platform over time within a growing team. You will bring:

• 6–7 years’ experience in Data Engineering or a similar mid-to-senior technical role
• Strong hands-on technical expertise with Python, SQL, and Snowflake
• Solid experience designing and operating AWS-based Data platforms (incorporating tools like Amazon MWAA/Apache Airflow and dbt Core)
• Deep understanding of Data Lake architectures, ELT/ETL orchestration, governance, and enterprise data platforms
• The ability to work on broader architecture and systems integration topics, rather than just data pipelines
• Fluency in English
• Knowledge of Asset Management systems (e.g., Maximo, maintenance, lifecycle management) (desirable)
• Experience working within the transport, infrastructure, or industrial sectors (desirable)
• Familiarity with construction and/or operations data (desirable)
