Cmi Big Data Java Developer(Ref47594)

Description du poste
- About CMI
- Capital Markets IT (CMI) is the IT department within the bank focused on solutions related to Capital Markets. This includes Front Office (FO) booking platforms, Risk Management (RM) control and regulatory reporting systems, financial product and contract valuation systems, and much more. It is the department most directly exposed to the bank’s financial operations.
- About MASAI
- MASAI is an ambitious project critical to the Bank’s strategic pivot towards data-centric operations. In the past, separate systems maintained their data separately, modeling the same data in incompatible ways and depending on ad-hoc and sometimes brittle data sharing mechanisms, creating a complex web of interdependent systems and no centralized repository of data. MASAI was initially created to satisfy regulatory requirements set out by the Basel Committee as part of their FRTB capital rules, but quickly became the central focus in the Bank’s push towards a more data-centric approach. It is based on Big Data technology, which allows horizontally-scalable management of data at and beyond the petabyte scale.
- About the Position
- As a member of the MASAI project’s development team, you will develop robust processes to ingest huge amounts of data from disparate systems, and build processes that transform and use that data. The core technology used is Apache Spark on top of HDFS, and development is primarily in Java. The position is ideal for someone with a strong interest in data processing and data science: either a confirmed expert in Big Data technologies or a strong developer keen on gaining expertise in that domain.

At least 8 years of software development experience
- At least 5 years experience working with Java
- A strong understanding of recent Java language features, such as lambdas, streams, and futures
- Good knowledge of algorithms and data structures, with strong fundamentals in complexity analysis
