Software Engineer

The Role

We're looking for a Software Engineer to join our Data Products team and help shape how critical Fixed Income data is built managed and delivered — to external clients and partners around the world. A key part of the role is evolving client-facing web UIs that make these data products easy to discover understand and use. You'll work on delivering high-quality data products that clients depend on for trading and analytics from backend to frontend as well as from ingestion to analytics and distribution. If you're curious about financial markets enjoy solving hard problems end-to-end (from UI to data) and want to own something that reaches beyond the firm's walls this role is for you. 

How You'll Help Take Us There

Web UI: 

• Own and evolve client-facing web frontends built with AngularJS and JSP; modern JavaScript or React experience is a plus. 
• Build and maintain backend data services required by those frontends including analytics caching and other integrations. 
• Partner with data platform information security QA and test automation engineers to deliver and maintain  intuitive secure and compliant workflows for internal and external data discovery and consumption. 

Data Engineering & Integration: 

• Design and build data pipelines for ingestion transformation and distribution using Java Python and SQL. 
• Implement asynchronous and concurrent patterns for high-throughput systems. 
• Work with streaming technologies — Kafka and JMS — for real-time and event-driven data delivery. 
• Primarily use Java to build these pipelines but also Python data libraries (Pandas Polars NumPy) for data wrangling and exploratory analysis where applicable. 

Data Products & Reference Data: 

• Contribute to instrument market data and general reference data pipelines— helping establish a trusted authoritative source for Fixed Income reference data delivered to clients. 
• Build and maintain data products that external clients and partners rely on — quality reliability and timeliness. 

Cloud & Infrastructure: 

• Build and maintain AWS-based data products using among other services: ECS / EKS Step Functions S3 Athena Aurora MSK and CloudFormation. 
• Follow security and observability best practices — IAM KMS encryption CloudWatch Grafana. Apply and maintain strict cost management best practices including optimizing data storage strategies (partitioning bucketing) for performance and cost. 

Software Engineering & CI/CD: 

• Contribute to automated build test and deploy pipelines using Jenkins Bitbucket and GitHub.
• Write clean modular well-tested code — unit and integration tests are part of the definition of done.
• Instrument systems with monitoring and alerting; own the reliability of what you ship.  

Collaboration & Innovation: 

• Partner closely with Development Product and Infrastructure teams — and stay mindful of the client experience your work supports.
• Leverage AI-assisted development tools (e.g. GitHub Copilot) to work smarter and move faster.
• Bring intellectual curiosity and a genuine interest in understanding the Fixed Income domain — we'll help you get there. 

What We’re Looking for  

• 4+ years of software engineering experience. 
• Proven experience building and maintaining production web UIs (AngularJS JSP or similar). Experience migrating UIs to a more modern JavaScript framework (React Vue or similar) is beneficial. 
• Strong Java skills; solid SQL; Python experience (especially for data analysis and scripting) is a plus. 
• Experience with Spring Boot or similar backend frameworks. 
• Experience with frontend testing practices and tools (unit / integration / end-to-end). 
• Experience with UI performance best practices including performance profiling and optimization. Experience working with event-driven or streaming systems (Kafka JMS or similar). 
• Hands-on experience with AWS (ECS / EKS Step Functions S3 Athena Aurora or equivalent cloud services). 
• Familiarity with CI/CD practices and tooling (Jenkins Bitbucket GitHub). 
• Comfortable working in Unix/Linux environments including scripting skills. 
• Confident using AI tools as part of your development workflow. 
• Strong communicator collaborative by default and eager to learn. 
• Interest in financial markets — Fixed Income experience not required but curiosity is.
