Description

You will help shape how financial risk is analysed. The team builds and runs the core platform for prime services risk and business intelligence.

• Proven work with message-driven systems such as Kafka, RabbitMQ or similar.
• A track record of leading technical initiatives, making architecture decisions and mentoring engineers, showing you multiply your team's impact.
• Solid CI/CD and Git experience with tools such as Jenkins or Tekton.
• Experience with containers and orchestration (Docker, Kubernetes, OpenShift) is essential.
• Excellent verbal and written communication, including explaining complex technical ideas to technical and non-technical audiences.
• Preferred: a track record of AI-driven development.
• Preferred: experience with Angular or React user interfaces.
• Preferred: experience in finance, or a strong interest in it, especially prime finance, counterparty risk or market risk.
• Preferred: an advanced degree (M.S. or Ph.D.) in computer science, engineering, mathematics or a related quantitative field.
• Preferred: hands-on experience with Apache Pinot or other OLAP datastores.
