Staff Software Engineer - DSP & AI Optimisation

We seek a passionate, experienced embedded software engineer to design, improve, and present DSP and AI workloads on the latest Arm-based platforms. At Arm, you will get to contribute to forward-thinking projects that advance tomorrow’s technology. This role presents a remarkable opportunity to work alongside a team of talented engineers to develop and apply next-generation solutions for our future challenging projects!

The successful candidate will work closely with hardware architects and software teams. They will bring up development platforms, port operating systems, and optimize compute-intensive workloads. They will also demonstrate the performance potential of Arm solutions. This role combines low-level embedded software development, processor architecture knowledge, performance optimization, and system-level integration., * Platform bring-up: Enable and configure embedded platforms, including bare-metal environments, RTOS, Zephyr, and embedded Linux.

• Performance optimization: Transfer and improve DSP, audio, vision, and AI workloads through the use of Arm architectural features like MVE, NEON, SVE2, and SME.
• Compute libraries: Develop and optimize mathematical and signal-processing kernels, including FFTs, filters, image processing, and ML preprocessing.
• System integration: Integrate sensors, memory subsystems, DMA, accelerators, and software components into complete processing pipelines.
• Benchmarking and profiling: Analyze CPU utilization, memory bandwidth, cache behavior, latency, and power consumption using hardware performance counters and profiling tools.
• Technical demonstrations: Develop representative applications showcasing the capabilities of Arm processors and accelerators.
• Collaboration: Work with processor architects, software teams, and silicon partners to identify performance bottlenecks and recommend architectural improvements., At Arm, we value our employees and strive to build an inclusive and collaborative environment. In return for your dedication and expertise, you will participate in ambitious projects alongside world-class engineers. You will receive support for professional development and have access to a range of benefits to improve your career and personal life. Join us and be a part of a company that is crafting the future of technology!, Arm’s approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team’s needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.

• Strong proficiency in C/C++ and low-level embedded programming.
• Solid understanding of processor architectures, memory hierarchies, caches, DMA, and interrupt handling.
• Familiarity in handling embedded operating systems like RTOS, Zephyr, or Linux.
• Practical experience in performance profiling and code optimization.
• Familiarity with DSP algorithms, fixed-point arithmetic, and SIMD/vector processing.
• Experience with embedded development tools, compilers, debuggers, and hardware evaluation boards.
• Strong problem-solving abilities and capacity to collaborate effectively within a group.
• Strong communication skills to effectively convey technical concepts.

Desired Skills and Experience

• Arm Cortex-M and Cortex-A architectures.
• MVE (Helium), NEON, SVE2, or assembly-level optimization.
