We're building the platform for creating consumer-facing AI voice agents.
Phone calls have long had a bad reputation. All of us have been stuck in long waiting queues, dealt with unhelpful support agents, or listened to endless hold music. Even though voice is the most natural way to communicate, it has never scaled for businesses.
We believe that every B2C company in the world - from energy providers, to telecoms, to insurances - will have AI voice agents that interact with their customers. The number of business-to-consumer conversations over the phone is going to explode in the coming years. As LLMs get better and better it will become an absolute no-brainer to use voice agents to provide consumers with a great experience.
The opportunity is massive and we know we can win.
This is a high-ownership role for a founding designer who cares about velocity and solving real customer problems. You won't just create mockups, you will own the entire design process end-to-end, speaking directly to customers and making core product and UX decisions. In short, you’ll have a significant impact on the direction of our high-growth, ambitious product.
You'll be our first full-time designer — with ownership over UX and UI across the entire product. This means you need to be comfortable designing for complex, AI-first workflows while maintaining the simplicity that makes our product accessible to non-technical users.
- Collaborate closely with customers to understand their needs and design solutions that solve their problems
- Own the design process end-to-end for new features
- Identify new AI product opportunities, design concepts, and build prototypes with our customers
- Create new intuitive interfaces that make sense in an AI-first world where traditional UI patterns don't apply
- Work side-by-side with engineers to ship high-quality features quickly
- Work experience designing UX and UI for software, ideally in early-stage startups working on B2B SaaS products
- You have great attention to detail and exceptional skills in product design (interaction design, visual design, and design systems)
- You don’t limit yourself to just static designs in Figma, but build interactive prototypes (with tools like v0, Lovable, Cursor, or Figma Make etc.)
- You love talking to customers to uncover real pain points and can independently drive the design processes from discovery through launch
- You thrive in fast-paced and ambiguous environments. You’re comfortable with uncertainty, learn quickly from mistakes, and focus on what matters.
- You care about shipping production-ready software, and have an eye for high-quality, well-crafted visual and interaction design, and a passion for UI details
- You have a strong interest in AI and LLMs, and you’re excited by the design challenges of voice interfaces.
- You align with our principles (https://principles.telli.com/)
- You take full ownership of projects
- You want to work in-person in Berlin
- You know what it takes to succeed in a fast-paced, high-ambiguity environment
- You know how to prioritize high-leverage work
- You want to work with a smart and driven team with (self-reported) low ego
- You want to help build a multi-billion dollar company from the ground up
- Strong portfolio showcasing your work on complex, user-centered products
- You prefer a remote-first environment
- You like to work on your own with minimum collaboration
- You have no prior experience working with software engineering teams
- You only want to work on visual design instead of the entire user experience
- You think AI is just hype and doesn't provide real value
- You want to work 9-5
- Above-market pay & equity
- Access to any (AI) tool that makes you more productive
