Principal Software Engineer

Role: Principal Software Engineer

Job Description

We are looking for an experienced Principal Embedded Software Engineer to join our team designing, developing, integrating and validating firmware for the latest Arm-based SoC platforms.

Our team works across a broad range of SoC firmware technologies, with particular emphasis on memory subsystems, coherent interconnects, high-speed and low-speed I/O, platform initialization and system bring-up. We are especially interested in engineers with expertise in these areas, including experience working across simulation, emulation, FPGA and silicon environments.

The role combines technical leadership and ownership of complex engineering deliverables with hands-on, low-level software development, integration, testing and debugging. You will work closely with hardware architects, silicon designers and software engineers to solve challenging system-level problems and drive technical decisions.

If you are passionate about developing innovative technologies and enjoy working at the intersection of hardware and software, we would like to hear from you.

Required Skills and Experience

Extensive experience in embedded systems and low-level firmware development, supported by a broad understanding of SoC architecture and platform software, is essential.

We are particularly interested in candidates with deep expertise in one or more of the following areas:

• SoC memory subsystems, including LPDDR or HBM, with experience in memory controller and PHY integration, initialization, training, bring-up and debugging.
• Platform firmware development, particularly UEFI firmware using EDK II, including hardware discovery, configuration and boot services.
• Trusted Firmware-A (TF-A), including secure boot, platform initialization and low-level firmware interactions.
• SoC interconnects and I/O subsystems, including coherent interconnects, PCIe, Ethernet and associated hardware initialization and bring-up.

In addition to the above specialisms, the successful candidate will demonstrate:

• Extensive familiarity with Arm system architecture, operating system fundamentals (preferably Linux), bootloaders and device drivers.
• Excellent C programming skills, with demonstrated ability to develop substantial new functionality and diagnose complex hardware/software interactions. Familiarity with Arm assembly language is desirable.
• Strong technical leadership skills, including the ability to make architectural and implementation decisions, resolve complex technical problems and guide other engineers.
• Experience collaborating across hardware and software teams to integrate, debug and validate complex SoC platforms.
• Excellent interpersonal and communication skills, including strong written and spoken English.

Nice to Have Skills and Experience

• Experience leading teams of software engineers, including technical mentoring or line management.
• Familiarity with open-source development practices and upstream contribution processes.
• Experience with software development lifecycle methodologies, including Agile.

In Return:

You will have the opportunity to learn about the latest Arm architecture features, working closely with highly skilled engineering teams on ground-breaking technology. You will be empowered to continually identify and roll out improvements to our ways of working.

Use of AI in Your Application

At Arm, we embrace the benefits AI can bring, including in recruitment. You may use AI to support your preparation, such as improving the clarity of written responses, practicing interview questions, or learning more about our industry. However, your application and interview responses must reflect your own thinking, experience, and abilities. We want to understand your authentic perspective, creativity, and approach to problem solving. As such, you may not use AI to complete assigned tasks as part of any assessments. If you plan to use AI-supported or assistive technologies as part of a reasonable adjustment, please contact [email protected] so we can support you.

Recruitment Adjustments and Accommodations

At Arm, we want to build extraordinary teams. If you need an adjustment or an accommodation during the recruitment process, please email [email protected]. To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation or adjustment requests will be treated with confidentiality, and information concerning these requests will only be disclosed as necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud, or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.

Hybrid Working

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.
