• Conduct thorough code reviews — including validation of testing results — and ensure large change sets are broken into reviewable units
• Collaborate across teams to implement and roll out solutions in both production and development environments.
• Proactively identify and resolve technical issues before they impact downstream systems

• Excellent collaboration and communication skills, with experience partnering across development teams on critical roll outs.
• Knowledge of financial instruments or a strong motivation to learn financial markets and concepts.

Nice to have :

• Experience with Git, Gerrit, Bitbucket, Gradle, and/or Ivy.

• Experience developing web applications using Spring Boot
• Experience with SWIFT MT/MX messaging standards.
• Hands-on experience with AWS, including data lake architectures (using Parquet file formats), Athena, and EC2, for building and operating datadriven, production-grade applications.
