Opera Sweden is looking for a frontend developer for our new mobile Crypto team.

We are the first major browser to integrate a native crypto wallet. As a front-end developer on our cryptocurrency team, you will be on the cutting edge of building web3 and making cryptocurrency the standard of the modern internet.

You will be part of a small, focused and supportive team of developers, QAs and business developers. We use Lean principles for day-to-day work and the best technical practices while striving to make the blockchain available to everyone. While we work hard, we also understand the importance of work-life balance and offer flexible working hours.

Role and responsibilities

Although this is a front-end position, you need to have a strong interest in (and ideally experience with) blockchain, Ethereum and/or Bitcoin. In this role you will implement and maintain features for our crypto wallet.


  • Work with the team to develop new features
  • Build pixel-perfect front-ends from design and interaction mockups
  • Take part in overall design, architecture and tech stack discussions

  • Web development skills, including:
    • Design of overall architecture of web applications
    • Building reusable code and libraries for future use
    • Optimization of applications for speed and scalability
    • Good understanding of git
  • Fluency in English, both written and spoken
  • Engineering knowledge: your code should be well-structured and comprehensible by other humans, not just computers

An ideal candidate has:

  • Deep understanding of crypto, blockchain or web3 technologies
  • Strong knowledge of web technologies
  • Experience developing features for a mass-market consumer product

What we offer:

  • An opportunity to experience the thrill and challenges of working at an international internet company with a huge global user base
