Job Description


We’re a blockchain startup, but we are helmed by early adopters and industry veterans that are building a very groundbreaking product suite that provides the user experience improvements needed to make blockchain technology truly mass adoptable. For example, we have a working prototype of a cryptocurrency wallet which provides interoperability between chains and human friendly addresses to make crypto transfers as easy as sending and receiving email, even between different types of tokens such as Bitcoin and Ethereum. Our demo of this prototype won Runner Up in the Startup Battlefield Europe competition hosted by TechCrunch in May, and more recently in August we’ve already put out a public code release of our IOV-core client.

Our development strides can be attributed to our efforts at recruiting top talent into blockchain coding, and it helps that our team is also expertly guided by talented veterans such as the original system architect and first technical employee of Lisk (which in its time was the most successful ICO in 2016 and second most successful ICO in history after Ethereum, before going on to reach a multi-billion dollar market cap in Q1 2017 as a top 20 project in the industry).

IOV was founded because we believe in the potential of blockchain tech to improve life for not only business operators, but everyone - in every industry, and every economy. We believe that potential won’t be realized, however, without solving the cross-chain transaction and user friendliness barriers that we’re building IOV’s products to solve. Our suite’s key components include the Blockchain Communication Protocol, the Blockchain Name Service, an SDK for developers, and the “universal wallet” we’re building for mainstream consumer usage.

We’re seeking a smart, self-motivated person to join our team as our first Front-end Engineer.

You’ll be working closely with your teammates to design and create prototypes and intuitive interfaces to improve the blockchain user experience. These are major industry challenges that we’re targeting and we’re passionate about the work, especially as an opportunity to do something innovative.

As our first front-end developer, the team will often look to you for advice and direction: you’ll be helping to shape our best practices and to choose frameworks and tools. You’ll also be responsible for moving your projects forward, communicating your progress and milestones to others, and clearly documenting your work.

Key Responsibilities:

  • The development of new highly responsive, web-based user interfaces
  • Working and collaborating with the rest of the engineering team
  • Implementing designs provided by the product and UI teams
  • Learning and understanding user interactions
  • Developing a flexible and well-structured front-end architecture, along with the APIs to support it


You love beautiful design, and working with others to transform concepts into real-world interfaces that are a joy for people to use. You love keeping up-to-date with the latest best practices and tools, and are constantly tweaking and improving the way you work.

You’re excited to solve engineering challenges in the most pragmatic way possible, and most importantly, you keep the end user in mind and love getting feedback from customers to help improve our products.

You can’t wait to join a team that loves their work as much as you do, and which affords opportunities for working on challenging and interesting projects that enable you to continuously learn, improve, and ship your work. Resonating with our philosophy that code is about communication, you are glad to explain your thought process clearly to your colleagues. As an excellent writer, you can therefore also communicate well in text, whether you’re drafting up a bug report, editing a wiki page, or chatting in Slack: our team is fully remote and stays in touch primarily via Slack, and weekly check-ins.

Key Qualifications:

  • B.S Degree in Computer Science or equivalent work experience
  • 4+ years of experience with JavaScript and REACT
  • Experience with HTML / CSS
  • Experience with REST API's
  • Knowledge of Gitflow
  • Team player

** IOV is an equal opportunity employer, supporting inclusiveness in all aspects of life, including Religion, Sex, Gender Identity, Sexuality, Age, Disability, Ethnicity and Race. **

Contractors must live in Europe with valid working visa. We embrace remote work, but maintaining the same time zone and ability to meet up face to face on a regular basis are essential for building a solid team at this early stage. (In the future, we hope to be able to integrate developers from more regions).
