Data Engineer (FAP-BC-HR-2022-204-LD)

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Job Description

Introduction

Are you an experienced and motivated data engineer with a passion for data modeling? Are you at ease with analysis, design and implementatoin of data pipelines and not afraid to optimise database queries, to dive into data integration processes or to configure and debug messaging/eventing systems? Then join an agile team of talented software developers and contribute to application software for CERN's Corporate Information Systems. CERN, take part!

You will join the Platforms Section of the BC Group (Business Computing) in the FAP Department (Finance and Administrative Processes), where 70+ talented international colleagues are responsible for delivering information systems for all of CERN’s business functions.

The Platforms section is responsible for the maintenance and development of the CERN FHR sector's reporting and data integration processes (e.g. finances, human resources, procurement...).

The product management driven group supports clients across the whole Organisation (HR, Finance, Planning, Safety, Security, Purchasing, Logistics, and Accelerator Operations). The type of products under the Group’s responsibility ranges from custom-made solutions for a few users to large and widely integrated systems with 15,000+ users. Hence, working for the BC Group provides numerous perspectives for being in touch with different technologies and business areas.

Functions

As a Data Engineer, you will join a self-organised agile product team and you will be responsible for maintaining, evolving, and re-engineering CERN’s administrative information systems, aligned with the group's strategy to modernise, replace, and consolidate legacy architectures and business-critical applications. More specifically, you will take on the following responsibilities:

• Design, implement and test data pipelines for data ingestion and data transformation across streaming and batch data flows
• Develop data models and architectures. Convert data into relevant datamarts.
• Participate in and lead cross-team technical initiatives and deliver proof of concepts demonstrating product feasibility.
• Maintain and improve group-wide high standards and guidelines of software engineering practices.
• Identify areas of improvement in the technology landscape of the group and recommend solutions.
• Mentor junior software developers.
• Provide user support including analysing user requirements, synthesizing, specifying and following-up on both software- and non-software related issues.

Qualifications

Master's degree or equivalent relevant experience in the field of computer science or a related field.

Experience:

• Demonstrated experience with SQL, PL/SQL and Oracle databases
• At ease with modern data warehouse design and architecture principles, patterns, and their application in the data integration ecosystems
• Demonstrated experience in the design and development of ETLs built on top industry standards (Pentaho Data Integration - PDI, Airflow and similar)
• Proven experience with event streaming platforms (Kafka)
• Experience with BI solutions and reporting tools such as Power BI
• Demonstrated experience with modern monitoring tools (Prometheus, Grafana)
• Proven experience of modern software development life cycle and DevOps processes (incl. build/test/deployment tool chain)
