Description & Requirements

The mission of Application Frameworks at Bloomberg is to deliver a seamless, industry-aligned, and fully supported application platform that enables a delightful Terminal experience.

The Bloomberg Terminal is powered by a reliable and performant JavaScript runtime known as R+. This framework is based on Chromium and Node.js and provides the foundation for application logic, system integration, and execution. R+ powers feature-rich applications across Bloomberg, including core Terminal experiences relied on every day by financial professionals worldwide.

The R+ App Engine team builds and evolves the runtime and infrastructure that make this possible. We design and own developer-facing JavaScript and TypeScript APIs implemented via native (C++) bindings. These APIs focus on runtime behavior, performance, and system integration rather than user interface development. Application developers rely on this infrastructure to create complex, high-performance software relied on by hundreds of thousands of users every day. Our platform efficiently runs hundreds of applications in multi-tenant processes on client machines. The work we do is foundational, highly visible, and critical to the stability and performance of the Bloomberg Terminal.

Another major focus of the R+ App Engine team is making Node.js a first-class citizen at Bloomberg. We are designing and implementing new runtime APIs that expose core Bloomberg technologies to JavaScript and TypeScript developers, enabling teams to build directly on foundational capabilities such as data access, messaging, and other platform services. This work shapes how a new generation of developer-facing APIs are defined, consumed, and evolved across the company.

What’s in it for you

You’ll work on software that runs on every Bloomberg Terminal and supports applications used daily by hundreds of thousands of professionals. This role offers the opportunity to own critical infrastructure, influence long-term technical and architectural direction, and help evolve a large-scale runtime platform while staying closely aligned with modern, industry-standard technologies.

Our team

The R+ App Engine team is responsible for Bloomberg’s application runtime and platform layers. Our work focuses on system-level services such as runtime orchestration and application lifecycle management, rather than UI frameworks or visual components. We build native infrastructure and expose it through carefully designed JavaScript and TypeScript APIs that integrate applications with the broader Bloomberg ecosystem.

We’ll trust you to:

+ Design, build, and maintain foundational runtime infrastructure that powers the Bloomberg Terminal

+ Develop high-quality JavaScript and TypeScript APIs backed by performant native implementations

+ Help define and drive architectural direction for widely used platform components

+ Devise innovative solutions to complex engineering and product problems in collaboration with engineers across Bloomberg

You’ll need to have:

+ 4+ years of professional software engineering experience

+ Strong production experience with JavaScript and/or TypeScript

+ Solid understanding of software design and development best practices

+ Experience working on complex systems or infrastructure with high reliability requirements

We’d love to see:

+ Experience working on runtimes, platforms, or developer infrastructure

+ Experience with C++, Rust, or other systems programming languages

+ Familiarity with Node.js, V8, or native language bindings

+ Interest in systems architecture and long-term platform evolution

+ Experience collaborating across teams on shared frameworks or services

+ Curiosity about modern application and runtime technologies
