Senior​/Software Engineer - LLM Inference Systems Source

Company:

Qualcomm Technologies, Inc.

Job Area:

Engineering Group, Engineering Group  Machine Learning Engineering General

Summary:

We are looking for experienced software engineers to help build and advance the software ecosystem for large-scale LLM inference on Qualcomm  this role, you will work at the intersection of open-source LLM serving systems, distributed systems, cloud-native infrastructure, and AI accelerator software. You will contribute to open-source projects such as llm-d and related LLM inference engines, while developing the integrations and capabilities required to run these systems efficiently and reliably on Qualcomm AI accelerators.

Depending on your background and interests, you may focus more heavily on either distributed LLM serving and orchestration or inference runtime and accelerator integration, while collaborating across both areas.

This is an opportunity to work directly with leading open-source communities and help shape the next generation of scalable, production-grade LLM inference infrastructure.

Minimum Qualifications:

• Bachelor's degree in Computer Science, Engineering, Information Systems, or related field and 4+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.

ORMaster's degree in Computer Science, Engineering, Information Systems, or related field and 3+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.

ORPhD in Computer Science, Engineering, Information Systems, or related field and 2+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.

Responsibilities Contribute features, improvements, bug fixes, and architectural enhancements to open-source LLM inference projects, including llm-d and other open-source LLM inference and serving projects.

Develop and improve support for Qualcomm AI accelerators in open-source LLM serving frameworks.

Work with upstream maintainers and open-source communities to design, review, and upstream Qualcomm-related functionality.

Develop and enhance inference engine integrations for Qualcomm platforms, including device abstraction, accelerator runtime integration, memory management, distributed execution, compilation, and performance optimization.

Develop and improve llm-d integration and deployment capabilities for Qualcomm platforms, including reference architectures, deployment blueprints, configuration, and operational tooling.

Design and implement distributed LLM inference capabilities such as:

Prefill/decode disaggregationKV-cache management and transfer

Distributed communication and high-performance data movement

Request routing and load balancing

Tensor, pipeline, expert, and other forms of model parallelism

Multi-node and scale-out inference

Autoscaling and resource management

Failure detection, recovery, and service resiliency

Integrate LLM inference software with Kubernetes and cloud-native infrastructure, including scheduling, autoscaling, networking, observability, and lifecycle management.

Profile, benchmark, and optimize end-to-end inference performance, including time to first token (TTFT), inter-token latency (ITL), throughput, memory utilization, and scalability.

Diagnose complex issues spanning model-serving frameworks, distributed runtimes, operating systems, networking, accelerator runtimes, and hardware.

Collaborate closely with hardware, firmware, compiler, runtime, Kubernetes, and product teams to define requirements and deliver end-to-end solutions.

Develop technical documentation, examples, reference deployments, and best practices to help customers and developers deploy LLM workloads on Qualcomm platforms.

Participate in architecture discussions and help influence the technical direction of Qualcomm's open-source LLM inference software strategy.

Qualifications Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field, or equivalent practical experience.

Strong software engineering and debugging skills.

Experience developing production-quality software in one or more of Python, C++, Go, or Rust.

Strong understanding of at least one of the following areas:

Machine learning or LLM inference systems

Distributed systemsAI accelerator or GPU software

Cloud-native/Kubernetes infrastructure ML compiler or runtime systems

Experience working with complex software systems and debugging problems across multiple layers of the stack.
