Shape a product that keeps our digital world awake

We’re on a mission to make downtime invisible. Thousands of DevOps and IT teams - from scale-ups to enterprises - use our incident-management platform 24/7 to react faster and communicate outages clearly.

As our first dedicated product designer, you’ll own the end-to-end user experience across web and mobile, turning complex, high-stakes workflows into delightfully simple interactions.

Responsibilities

• Evolve and govern ilert’s cross-platform design system (Web + Mobile)
• Balance clarity and density in data-rich dashboards and timeline views

• Validate releases with A/B tests and continuous user feedback loops
• Champion accessibility (WCAG 2.1 AA) and performance best practices

• Portfolio that proves user-centric thinking, visual craft and shipped impact
• Mastery of Figma (auto-layout, variants, tokens) and basic motion/animation
• Hands-on with design systems, component libraries and responsive layouts
• Fluency in English (our working language); German is a bonus
• Solid grasp of HTML/CSS limits and possibilities - enough to speak dev

Bonus points

• Ran quantitative research (surveys, funnel analytics) or A/B experiments
• Experience with real-time data products

Benefits

• Product-centric: 100 % focused on solving a mission-critical pain felt by every always-on business
