What we do

Bloomberg's Connectivity & Integration (BCI) group provides a platform for customers to integrate Bloomberg products with their own highly complex and time sensitive software systems. With ever growing demands for more capabilities in data transformation and analytics, we are building our next generation Integration Platform offering through an architecture that uses a combination of open source, third party, and in-house technologies to meet these demands.

Our team owns and develops the critical Transformation Engine that sits at the heart of the Integration Platform product. The Transformation Engine provides customers and Bloomberg Implementation Specialists with a visual programming language as part of a no-code toolkit to extract, transform, enrich and process data in transit between Bloomberg and third-party systems.

From a technical perspective we regularly work across a breadth of domains:

• Service-oriented architecture
• Highly available, fault tolerant and self-healing distributed systems
• Language design and compilation
• User interface & experience development

Our infrastructure for the Transformation Engine currently exists in two main flavors. We have our legacy product which is developed predominantly in .NET Framework. We are actively in the process of retiring this and moving users to our next generation architecture.

Our next generation architecture is developed in .NET Core and Java targeting Linux environments. It is built as a component of our larger Integration Platform, and is in active development with production deployments.

We also develop services to support and manage the Transformation Engine in Python, Java, Typescript and React.

As we continue to decouple the legacy and next-gen systems, we are actively assessing and migrating shared code from .NET Framework to .NET — and we are looking for someone with deep C# expertise to lead that effort.

What you'll do

You'll own our C# and .NET strategy and contribute across everything the team builds. Your responsibilities will include:

• Be our subject matter expert on C# — architecture, stability, performance and scaling
• Lead the team's technical strategy around .NET best practices and development lifecycle
• Design and implement feature and performance enhancements for our products
• Contribute across the team's full technology stack — .NET, Java, Python, Typescript and React
• Participate in the team’s on-call rotations for incident response and business-hours support for users building their transforms

Current and upcoming projects include:

• Implementing the next generation of our Transform code-generation, compilation, and execution framework
• Enhancing the Transform authoring experience with new toolkit features, including AI-powered program generation and explanation
• Improving resilience in the leader-election and job-submission distributed systems of our workflow engine

How we work

We are an autonomous and collaborative team of 8 engineers with a high degree of influence over our project roadmap. You will benefit from working closely with other experienced engineers and product counterparts. We work in two-week sprints and plan our projects with six sprint product increments.

Bloomberg has an active C# Guild — a company-wide community focused on C# best practices and development. As our C# expert, you’ll have the opportunity to dedicate part of your working hours to guild efforts, influencing C# practices at Bloomberg-wide scale, and bringing those practices back to our team.

Apply if you are interested in the domain and have:

• 4+ years experience in software development with deep expertise in C# and the .NET ecosystem
• Strong understanding of C# internals — threading, async/await patterns, performance profiling and diagnostics
• Experience working with distributed systems and service-oriented systems/architectures

Additional nice-to-haves:

• Hands-on experience migrating codebases from .NET Framework to .NET Core
• Experience establishing engineering best practices and mentoring teams in modern C# development
• Experience with functional programming (our legacy product compiles to F#)
• Experience with front-end development using WPF and/or React
