A better internet, where privacy is the default, is possible. Building this better internet might seem daunting or even unthinkable, but at Proton, this is what we do every day.

Proton was founded in 2014 by a group of scientists who met at the European Organization for Nuclear Research (CERN). Our first product, Proton Mail, is now the world’s largest encrypted email service. Subsequent Proton products, such as Proton VPN, Proton Calendar, and Proton Drive, give our users full control over how and with whom their data is shared.

Today, Proton makes privacy universally accessible. Journalists from outlets like The Guardian and The New York Times, some of the world’s largest organizations, and people in more than 180 countries have signed up for over 100 million accounts. Our diverse and dynamic team is made up of more than 400 members representing over 40 different nationalities. While we are based in Geneva, Switzerland, we have offices in Zurich, Prague, London, Vilnius, Skopje, Taipei, and many more employees working remotely around the world.

Join one of Europe’s fastest-growing companies to help us solve challenging problems and build new products that will reach hundreds of millions of people. We want to create more than just one of the world’s most impactful tech companies; we want to create a new internet that serves the interests of all people. We need you, your voice, your ideas, and your ambition to make it happen.

• Champion AI-native design practices, actively using tools like Cursor, Claude Code, Figma AI, v0, and Uizard to prototype faster, explore more options, and ship better
• Drive measurable business impact by analyzing adoption and usage of delivered solutions, proposing iterative improvements based on user insights and product metrics

What You'll Bring to the Role

• 6+ years of Product Design experience on complex B2B SaaS products
• Proven track record of shipped features or products with measurable business impact
• Demonstrated leadership as a design authority (not necessarily as a manager)
• Experience representing design with Leadership, Sales, Customer Success, and Marketing stakeholders

Our Hiring Process

1. A 30/45-minute phone call with one of our recruiters to discuss your background, expectations, tell you more about Mirakl
2. A 1h30 job-related interview with the Product Director and the Head of Design to dive deeper into your expertise and explore how your skills could contribute to our projects
3. Two 45-minute interviews giving you the chance to meet your potential future colleagues at Mirakl while discussing key projects of your career 

✨ Portfolio Guidelines

• Consider your portfolio as a UX exercise. Think about your audience (recruiter, hiring manager), the time available (often a few minutes), and the context in which it will be reviewed (between meetings, sometimes on mobile). Make sure navigation is simple and fast, with a clear structure to move from one project to another and jump to the most important sections. Keep in mind that the portfolio often replaces a design exercise during the hiring process.
• Be concise and decision-oriented. For each project, make the content scannable in a few seconds: the problem, your role, constraints, key choices, and the outcome. Avoid long texts and generic process or workshop descriptions that could apply to any project. If you want to show your method, do it in a dedicated section.
• Put visuals at the center. Use high-quality screenshots and highlight the result of your work. Show the expected level of craft, and briefly explain what the reader should focus on.
• Treat the portfolio as a personal branding exercise. It is a personal project that should reflect your personality while staying professional. The interface should feel spacious, leave room for visuals, and reflect current standards (typography, hierarchy, spacing, clarity).
• Select a small number of highly relevant projects. It is better to show 2 to 4 strong case studies tailored to the role than many average projects. Choose the ones where your impact and leadership are the most visible.
• Clarify your contribution and your level of leadership. As a Lead, we want to understand how you framed the problem, aligned stakeholders, made decisions, prioritized, and improved the practice (guidelines, design system, rituals, quality).
• Show impact, not only screens. Add results when possible (conversion, adoption, time saved, quality, reduced support). If you do not have metrics, explain which signals you used (feedback, testing, analytics, learnings) and what you changed as a result.
