Anywhere in Europe Setup: WFH/Remote

At Dash0, we're not just building another observability tool; we're on a mission to bring observability closer to the developers; make it a part of their everyday work. We believe that getting deep insights should be easy and accessible. Our customers praise our simpler solution that empowers developers, and we're scaling fast. We’re looking for Product Engineers to join our groundbreaking teams, like our Agent0 team, responsible for our Agenting AI Platform for Observability, or our Intelligent Edge team, allowing our customers to reduce their observability spend, among others.

And that's where you come in!

The Challenge You'll Tackle:
  • Translate complexity into simplicity. Our users face billions of signals. Your challenge is to architect and build a highly performant, intuitive, and data‑rich user interface using React and Type Script that makes exploring this data feel effortless and insightful, not overwhelming.

  • Build a scalable and resilient frontend architecture. As we add more powerful features, you will co‑own the component design, state management, and overall structure of the frontend. How do we build for speed and ensure our UI remains fast and performant, even with huge datasets? You'll be at the heart of these critical decisions.

  • Champion the user experience. You will work closely with product, design, and backend engineers to define not just how the product looks, but how it feels. You'll be the advocate for the user, ensuring every interaction is purposeful. This is where we need you to be a Product Engineer, not just a software developer!

What Success Looks Like (and How You'll Get There):
  • Within 1 week, you'll have shipped your first piece of production code.

  • Within 3 months, you'll have shipped significant, user‑facing features, directly improving how our customers visualize their data and diagnose issues.

  • Within 6 months, you'll be a go‑to expert for our frontend architecture, mentoring other engineers, and driving best practices with Tailwind CSS and our testing frameworks. You'll be working alongside some very talented engineers who are eager to collaborate and learn with you.

  • Within 12 months, you'll have played a pivotal role in shaping the next generation of the Dash0 UI, helping us build a product that is powerful and a joy to use.

We're looking for someone who:
  • Has extensive experience building complex, data‑intensive applications with React and Type Script and good knowledge of charting libraries (e.g., Recharts, D3).

  • Is deeply familiar with modern frontend practices, including component‑based architecture and state management.

  • Expertly leverages AI and agentic coding tools to accelerate development, applying deep technical judgment to verify, refine, and own the final output.

  • Loves crafting beautiful, high‑performance user interfaces and has a keen eye for detail.

  • Is passionate about observability and making developers' lives easier.

  • Thrives in a fast‑paced startup environment where you can make a huge impact.

  • Has experience with testing frameworks and writing well‑tested code.

  • Is familiar with consuming RESTful APIs and collaborating with backend teams.

  • Has a working knowledge of server‑side development.

Must Haves
  • Ability to apply technical judgment to verify and refine AI output.

  • Experience leveraging AI / agentic coding tools.

  • Strong ownership mindset (Product Engineer vs pure frontend dev).

  • Comfortable in fast‑paced startup environments.

  • Experience…
