• A strong portfolio showcasing your ability to translate complex design concepts (Figma, Sketch, etc.) into high-quality, pixel-perfect code.

• Hands-on experience building, maintaining, or contributing to a component library or design system (e.g., using Storybook).

• Excellent communication and collaboration skills, with a proven ability to work effectively with designers and product managers to scope work and find scalable solutions.

• A pragmatic and product-oriented mindset, capable of balancing technical debt, design intent, and development velocity.

Preferred Skills

• Experience with UX prototyping and iterating in both high-fidelity (Figma) and code-based tools.

• A keen eye for motion design and experience implementing subtle microinteractions and animations.

• Familiarity with web accessibility (WCAG) and building inclusive interfaces.

• Experience working on large-scale, platform-level products used by multiple teams.

• Ability to triage and prioritize a backlog of small enhancements and bugs based on impact and effort.

Why Join Us?

• Bridge the gap between design and engineering on a high-visibility, high-impact platform team.

• Directly address and solve platform-wide customer pain points, improving the experience for millions of users.

• Shape the future of the Cloudflare UI by building its foundational patterns and exploring ambitious 'North Star' concepts.

• Join a collaborative, fast-moving team that values high-quality, scalable design and rapid iteration.

What Makes Cloudflare Special?

We're not just a highly ambitious, large-scale technology company. We're a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare's enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released.

Here's the deal - we don't store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.

As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

This role is part of Microsoft AI's Superintelligence Team. The MAIST is a startup-like team inside Microsoft AI, created to push the boundaries of AI toward Humanist Superintelligence , ultra-capable systems that remain controllable, safety-aligned, and anchored to human values.

We are looking for a design leader who is obsessed with how AI feels , not just how it looks. You'll own the end-to-end design quality of our model's personality, tone, and user-facing experiences across MM Labs, Playground, marketing surfaces, and model personality specification.

This is a player-coach role: you'll spend roughly 80% of your time doing hands-on IC work (model personality design, UX prototyping, interaction design) and 20% coaching and growing a small team of model and UX designers.

Your team includes model designers with linguistics backgrounds who shape how the model speaks, responds, and behaves , and UX designers who translate that into product surfaces. You set the creative bar for both disciplines.

The right person for this role has exceptional design taste and craft, a deep intuition for language and personality, and the drive to personally produce work that sets the standard for the team.

This is a small team where everyone builds. There is no room for armchair leadership , you will be in the work daily, reviewing SFT data quality alongside your model designers, critiquing interaction flows with your UX designers, and prototyping experiences yourself.

You will ship regularly, and your work will directly shape how millions of people experience our AI.

Responsibilities:

Own the creative vision for model experience: Define and evolve how our AI models look, feel, speak, and interact across all surfaces , establishing a coherent design language that spans personality, tone, visual design, and interaction patterns.

Do the work yourself: Personally produce high-quality IC output , whether that’s crafting model personality specifications, designing interaction prototypes, defining prompt taxonomies, or building evaluation frameworks for response quality.

Shape model personality and tone: Work directly with model researchers to define and refine the model’s character, voice, and communication style.

Translate abstract personality goals into concrete SFT data strategy, quality rubrics, and evaluation criteria.

Drive UX for key product surfaces: Own the experience design for MM Labs, Playground, marketing pages, and model specification tools.

Ensure every surface reflects world-class design craft and a deep understanding of how users interact with AI.

Coach and grow a small team: Manage 4-5 direct reports across model design and UX design.

Set direction, run rigorous critiques, unblock your team, and raise the quality bar , while keeping your own hands in the work.

Bridge linguistics and design: Serve as the connective tissue between model behavior (how the model responds) and product experience (how users perceive and interact with those responses).

Ensure linguistic quality and design craft reinforce each other.

Partner across research and engineering: Collaborate closely with model researchers, product managers, and engineers to influence model training priorities, evaluation rubrics, and user-facing capabilities from the earliest stages of development.

Build evaluation systems for design quality: Define what “good” looks like for model personality and UX.

Build rubrics, run evaluations, and create feedback loops that connect user experience insights back to model training.

Qualifications:

Bachelor’s Degree in Product Design, Human-Computer Interaction, Interaction Design, Communication Design, Linguistics, or related field AND 8+ years experience in product design, experience design, or a related creative discipline OR Master’s Degree in a related field AND 6+ years experience OR equivalent experience (e.g., demonstrated track record of shipping design work that shaped product identity and user experience)

2+ years of experience managing or mentoring designers, with a strong preference for player-coach roles where you remained deeply hands-on

A portfolio that demonstrates exceptional craft in interaction design, visual design, or content/personality design , with evidence of personal IC contribution, not just direction-setting

Experience designing for AI, LLM, or conversational systems , or a demonstrated deep understanding of how language, tone, and personality affect user trust and experience

Comfort working across disciplines: you can review SFT data quality with a linguist in the morning and critique a Figma prototype in the afternoon

Track record of shipping products end-to-end in ambiguous, fast-moving environments where you owned both the vision and the details
