Join Arm’s Chandler Characterization team to validate and characterize next-generation Arm SoCs and help customers bring products to market.
As a Senior Post-Silicon DDR Characterization Engineer , you will focus on DDR/LPDDR memory subsystems, characterizing silicon across process, voltage, temperature, and frequency conditions. You will collaborate across engineering teams to analyze results, debug issues, and improve silicon performance.
Responsibilities:
• Develop and enable system-level stress workloads on Linux and Bare-Metal SW environments!
• Collaborate with post-silicon validation team to leverage test content to characterize silicon at the system level.
• Debug and resolve system issues and bugs
• Develop test plans and implement tests for characterizing silicon at the system level
Required Skills and Experience :
We are looking for experience in pre- or post-silicon validation and characterization, with an understanding of silicon power, performance, and PVT behavior.
• Experience with DDR/LPDDR architectures, including training, calibration, timing, and PHY operation
• Software skills including C/C++, Arm assembly, Python, or scripting languages
• Experience with voltage/frequency margining and silicon operating limits
• Experience debugging silicon and system issues using scopes, logic analyzers, debuggers, or similar tools
• Ability to analyze data, solve complex problems, and communicate technical findings
“Nice To Have” Skills and Experience :
Experience with DDR/LPDDR PHY characterization, memory-controller interactions, and LPDDR4/4X, LPDDR5/5X, DDR4, DDR5, or related technologies is helpful.
• Experience characterizing memory performance, stability, operating margins, and failure behavior
• Experience developing Python automation for characterization and data analysis
• Experience with low-level C, firmware, hardware control, or silicon debug
• Experience with Arm-based SoCs, CPUs, or memory subsystems
• Understanding of system-level testing and correlation with manufacturing test
You will succeed in this role by collaborating effectively, continuing to learn, and applying strong analytical and interpersonal skills to sophisticated silicon challenges!

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 accommodations@arm.com 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 accommodations@arm.com . 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.
