Join to apply for the Senior Frontend Engineer role at Bitfly

Do you love crafting elegant, high-performance user interfaces that bring complex data to life? Does the idea of working on a public-facing platform used by thousands of blockchain enthusiasts excite you?

Join us at bitfly as a Frontend Engineer and help build the next generation of beaconcha.in – our popular open-source Ethereum blockchain explorer. You’ll work in a tight-knit, expert team on meaningful features and user experiences that make blockchain data accessible to everyone. From validator dashboards to transaction deep dives – your application will be seen and used by people all over the world.

No blockchain experience? No problem – curiosity and a passion for frontend engineering are what we care about most.

About The Company

Bitfly is a well-funded scale-up based in Vienna, Austria (with a fully remote option). We’re the creators of beaconcha.in, one of the most trusted and performant blockchain explorers for Ethereum and more. We process massive volumes of data from both the execution and consensus layers, including full archive and beacon node indexing, and surface this information in real-time for users across the world.

Our mission: make blockchain data visible, useful, and trustworthy.

We’re a small, international team that values clear communication, ownership, and curiosity. We believe in building robust systems and beautiful user experiences. You’ll join a company where your ideas matter, your work is seen, and where shipping great products is more important than strict processes or long meetings.

What You’ll Do

As a Frontend Developer at bitfly, you’ll be a core contributor to the frontend of beaconcha.in. You’ll own features end-to-end, from concept to release, and have a direct influence on how blockchain data is experienced by users.

Your day-to-day might include:

• Designing and implementing new features in Vue.js and Nuxt.js for our open-source explorer.
• Working closely with designers and backend engineers to create smooth, intuitive user journeys.
• Translating complex blockchain data into clean, performant, and visually engaging interfaces.
• Iterating quickly based on feedback, and helping shape our product roadmap through your insights and ideas.
• Championing frontend best practices – Take ownership, innovate, and directly influence product development.
  
  

This is a hands-on, product-facing role with plenty of autonomy and space to grow.

What We’re Looking For

We’re searching for a frontend engineer who cares deeply about UX, code quality, and continuous improvement. Ideally, you bring:

• 5+ years of experience building production-grade frontend applications.
• Deep knowledge of Vue.js and Nuxt.js.
• A strong eye for visual and interaction design – you don’t need to be a designer, but you care about aesthetics and usability.
• Familiarity with component-based architecture, state management, and modern JS tooling.
• A proactive, user-focused mindset and strong self-organization.
• Great communication skills in English – written and spoken.
  
  

Bonus Points If You…

• Are curious about blockchain, cryptography, or distributed systems and want to grow your knowledge.
• Have experience visualizing complex data (graphs, charts, dashboards, etc.).
