You'll work closely with developers to support complex, high-performance systems used for market data processing, regulatory reporting, and compliance analytics. This is a hands-on role that gives you the freedom to dig into issues - sometimes right down to the code.
Key Responsibilities
* Monitor and operate production systems supporting regulatory reporting and surveillance functions
* Investigate and resolve data-related alerts and system issues, including code-level debugging when necessary
* Collaborate with developers to troubleshoot complex issues and drive long-term improvements
* Provide L1/L2 support to users across the firm (typically 2-10 issues per day), escalating to L3 when required
* Assist in onboarding new teams and applications to the platform support model
* Continuously refine monitoring processes and documentation as the platform evolves
What We're Looking For
* Experience supporting and troubleshooting high-performance applications in a financial services environment
* Strong Linux skills and comfort working in command-line environments
* Understanding of market data and/or order data systems, including protocols like FIX or exchange-native formats
* Strong analytical and problem-solving mindset
* Ability to navigate or debug object-oriented code (Java and Python preferred)
* Familiarity with version control tools (Git or SVN)
* SQL proficiency - from writing queries to basic database operations
* Exposure to cloud infrastructure, ideally AWS
* Bonus: Experience with streaming/data tools such as Kafka, Spark, or Delta Lake
Technology Stack & Environment
You'll be working with:
* AWS, Kubernetes, Kafka, Argo
* Java 17, Python 3, HDF5
* Distributed systems processing large volumes of market and order data
* A globally distributed team covering Europe and North America
Why Join This Team?
* Work closely with developers and gain exposure to complex systems architecture
* Be empowered to investigate issues deeply and shape solutions
* Join a respectful, collaborative culture that values outcomes over process
* Use the right tools for the job - and keep learning as the tech evolves
