**Job Description: Experience Design Strategist (AI-Enabled Change)**
**About the Role**
As a Experience Design Strategist embedded in People & Communities (P&C) change initiatives, you design how people build the knowledge, skills, and confidence needed to adopt new ways of working. You recognize that learning is not a discrete event in a change journey - it is woven through every phase, from early awareness to sustained behavior change.
In this role, you specifically leverage AI-enabled learning technologies to personalize the learning journey directly in the flow of work. By analyzing complex workflows you will identify opportunities for AI augmentation and enablement interventions that appear right when the user needs them, ensuring that employees are not only prepared for change but are empowered to interact effectively with AI tools to enhance their performance.
**What You'll Do**
**Experience Design for Change**
+ Design experience frameworks and journeys that are sequenced to the phases and emotional arc of a change initiative, integrating AI-driven adaptive learning paths that adjust to individual users needs.
+ Develop audience-segmented strategies that account for varying roles, prior knowledge, and readiness levels, utilizing AI tools to deliver just-in-time content.
+ Translate change management goals into AI-augmented learning/enablement interventions that address knowledge and skill gaps, including simulations and interactive AI coaching modules.
+ Design for the full learning ecosystem, ensuring AI-enabled performance support is available within the flow of work to reinforce training.
**Integrated Experience Design**
+ Prioritize Performance in the Flow of Work: Shift away from traditional classroom or eLearning-centric models by embedding performance support, AI-augmented guidance, and actionable insights directly into the tools and platforms employees use daily.
+ Facilitate Social Ecosystems: Design and curate social-based environments-such as peer-to-peer coaching networks, communities of practice, and collaborative sense-making forums-to reinforce desired mindsets and behaviors through shared experience.
+ Drive Organizational Readiness: Develop strategies that treat readiness as a dynamic state, utilizing data to identify friction points and deploying targeted interventions that support employees exactly where and when they need it.
**Behavioral & Transfer Strategy**
+ Analyze workflows to identify where AI augmentation can reduce friction; design interventions that teach employees how to effectively prompt, interact with, and collaborate alongside AI tools.
+ Apply knowledge application principles to ensure that AI-augmented tools are perceived as performance enhancers rather than technical hurdles.
+ Work with managers to design their role in reinforcing AI-human collaboration, modeling desired behaviors for using AI in daily decision-making.
**Evaluation & Measurement Design**
+ Build multi-level evaluation frameworks that measure the impact of AI-augmented learning interventions on behavior change and organizational productivity.
+ Use AI-powered analytics to identify leading indicators of adoption, such as engagement with AI tools, confidence shifts, and real-time performance improvements.
+ Create feedback loops that allow learning design to be adjusted during rollout based on real-time data from AI-enabled platforms.
**Collaboration & Stakeholder Engagement**
+ Partner with subject matter experts to identify where AI can solve specific adoption barriers.
+ Facilitate co-design sessions to ensure that AI-augmented workflows are grounded in actual user needs and constraints.
+ Communicate the strategic value of AI-enabled learning to senior leadership, articulating how these technologies accelerate adoption and business impact.
**What You Bring**
**Experience**
+ 4-7 years of experience in learning design, instructional strategy, or change enablement, with a strong focus on digital transformation.
+ Proven experience designing interventions that incorporate AI-enabled tools, chatbots, or adaptive learning platforms.
+ Experience analyzing workflows to identify and implement AI augmentation opportunities.
**Skills & Mindset**
+ Strong learning architect who thinks in sequences and ecosystems, with the ability to integrate AI tools into learning frameworks.
+ Expertise in performance consulting, with a focus on designing solutions that integrate into the existing work environment rather than pulling employees away from it.
+ Proven ability to facilitate social-based environments that foster peer-to-peer knowledge exchange and cultural alignment.
+ Deep understanding of AI literacy-able to teach others how to interact with AI models and interpret AI-generated outputs.
+ Comfortable with both qualitative insights and quantitative data, specifically regarding how AI adoption metrics correlate to business outcomes.
+ Clear communicator who can translate AI technology for non-technical stakeholders and explain its role in a broader change strategy.
**Preferred**
+ Experience with AI-driven performance consulting methods.
+ Familiarity with the ethical considerations and change management challenges associated with AI implementation in the workplace.
+ Experience designing manager enablement programs that focus on leading teams through AI-driven process transformations.
+ **Proven ability to build or configure AI agents to support lower-complexity learning design tasks (e.g., generating content outlines, FAQs, or basic templates), enabling non-L&D or non-change management teams to self-serve and scale learning support.**
**How Success Is Measured**
+ Strategies that successfully integrate AI technologies to improve engagement and speed-to-competency.
+ Evidence that employees are successfully adopting AI-augmented workflows as part of the broader change initiative.
+ Evaluation frameworks that effectively use AI-driven data to provide actionable insights to sponsors and change leads.
**What This Role Is Not**
This is not a content developer, eLearning producer, or training coordinator role. While you may conduct some of these tasks and/or collaborate with those practitioners, your distinct contribution is the strategic design of how AI-enabled learning supports behavior change and how that progress is measured. You design the architecture; you and others build within it
**Why Cisco?**
