Principal UX Researcher, AI & Developer Platforms

Job Overview:
Arm is shaping the software foundations that bring intelligence from cloud to edge. As part of the AI & Developer Platforms team, you will lead high-impact UX research focused on how developers build, optimize and deploy AI-enabled software across Arm's ecosystem.
This role sits at the intersection of developer experience, AI platforms and hardware-aware software. You will study the surfaces developers use every day, including tools, GUIs, CLIs, APIs, documentation, runtimes, workflows and agent-mediated experiences. The goal is to help Arm define what developer experience should mean while developers establish direction. They coordinate automation, evaluate confidence, debug failures, and balance tradeoffs across performance, deployment, and ecosystem constraints.
This is an individual contributor role for a principal level researcher who can shape ambiguous problem spaces, influence product direction and bring external developer, customer and partner insight into strategic decisions.
Responsibilities:

• Shape strategic UX research across AI & Developer Platforms, ensuring well-defined priorities, high-quality delivery, and measurable product impact.
• Contribute to defining the future of AI-native developer experience as it reshapes how developers work across tools, GUIs, CLIs, APIs, documentation, runtimes and agent-mediated workflows.
• Identify high-value research questions and build pragmatic research approaches that inform product, platform and ecosystem decisions.
• Bring external developer, customer and partner insight into Arm's decision-making.
• Translate research findings into practical design principles, product implications and recommendations that improve developer confidence, adoption, efficiency and developer success.
• Represent developer needs in planning, roadmap and leadership forums, especially where hardware targets, runtimes, deployment environments, performance tradeoffs and ecosystem complexity shape the experience.
• Raise the quality of research practice by sharing methods, mentoring peers and helping teams make better evidence-based decisions.

Required Skills and Experience :

• Proven experience leading complex UX research initiatives in product, platform, developer tooling, AI or technical ecosystem environments.
• Strong command of qualitative and quantitative research methods, with the judgement to choose approaches that fit the ambiguity, risk and decision at hand.
• Experience crafting research strategy and influencing product direction without relying on formal authority.
• Ability to influence senior team members through clear insight, sound judgment and business-relevant recommendations.
• Fluency in developer tools, AI platforms, enterprise software or related ecosystems.
• Strong systems thinking, with the ability to connect developer needs, workflows, platforms, automation and ecosystem constraints.
• Excellent written and verbal communication skills for leadership, customer or partner-facing discussions.

"Nice To Have" Skills and Experience :

• Master's degree in Human-Computer Interaction, Cognitive Psychology, UX Design, Engineering Design or a related field, or equivalent practical background.
• Background researching or defining AI-native user experiences, including how people set intent, supervise progress, evaluate confidence, recover from errors and collaborate with agentic systems.
• Familiarity with developer platforms, AI frameworks, runtimes, APIs, performance tooling, enterprise software or technical ecosystems.
• Track record of using external research, market signals, partner input or community engagement to shape product strategy.
• Ability to represent research externally through customer engagements, partner studies, industry forums, publications or conference talks.
• Hands-on use of AI to improve the speed, quality or scale of user research, including research planning, analysis, synthesis, insight generation, repository management or participant workflow support.

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.
