Senior Java Engineer (FAP-BC-AS-2019-102-LD)

  • Geneva, Switzerland
  • Contract

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 Java developer with a passion for delivering complex and compelling information systems? Are you at ease with server-side technologies, particularly within the Java ecosystem, with hands-on experience in the modernisation of software systems? Have you guided organisations in the transition from monolith-based architectures to microservices? Then join an agile team of talented software developers and contribute to application software development for CERN's Corporate Information Systems. CERN, take part!

You will join the Business Computing Group (BC), where 70+ talented international colleagues are responsible for delivering information systems for all of CERN’s business functions.

The product management driven group is working for clients across the whole Organization (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.

As a Senior Java Engineer, you will join a self-organised agile product team and you will be responsible for evolving, re-engineering and maintaining the back end of 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, develop, and test new features and software components.
  • 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.
