Job description

Experienced Machine Learning Framework/Runtime Software Engineer

Specific Skills and Experience Required
We’re looking for strong C++ software development experience, ideally gained while building machine learning inference engines, runtime systems, or backend integration frameworks. Experience working with a machine learning inference framework such as LiteRT, TensorFlow Lite, ONNX Runtime, or a similar technology is also important.

A good understanding of how AI models execute in practice is essential, including graph processing, operator execution, memory management, and backend integration. This role involves analysing, investigating, diagnosing, and resolving complex functional or performance issues across frameworks, runtimes, compilers, drivers, and hardware abstraction layers.

The work brings together engineers across runtime, compiler, driver, and hardware teams to design, develop, integrate, test, and optimise solutions within a large, modular codebase. Strong analytical and problem-solving skills, combined with an interest in machine learning systems, AI acceleration, and performance optimisation, will support success in the role.
Beneficial but Not Required
Experience across every area below is not expected. Relevant knowledge or experience could include:

• Developing delegates, execution providers, plugins, or other backend integration mechanisms
• GPU programming or machine learning acceleration technologies such as Vulkan, OpenCL, TOSA, or compute kernels
• Designing or implementing Ahead-of-Time or Just-in-Time compilation flows for AI workloads
• Transforming graphs or working with operator partitioning, scheduling, memory planning, or model optimisation
• Validating, benchmarking, profiling, or analysing AI model performance
• Developing compiler technologies, intermediate representations, or hardware abstraction layers
• Building automated tests and CI/CD workflows for large-scale software projects
• Applying AI-assisted development tools responsibly to improve engineering productivity and software quality

What You Will Learn and Develop
Interested in exploring how machine learning models move from high-level frameworks through the software stack to hardware acceleration?

This role provides opportunities to deepen expertise in machine learning runtime development and hardware-accelerated AI execution. The work spans the end-to-end AI software stack, from framework-level model execution and backend delegation through compiler flows to NGP acceleration.

Working collaboratively across Arm provides exposure to inference engines and runtimes, accelerator integration, operator partitioning and fallback mechanisms, AOT and JIT compilation, model validation and benchmarking, performance optimisation, and automated validation workflows.

There are also opportunities to build a broader understanding of how machine learning frameworks, software, compilers, and hardware come together to deliver efficient AI experiences on Arm technology.
Working at Arm
At Arm, we want our people to learn, contribute, and grow while working on technologies shaping the future of AI and computing.
