About the Role

We’re looking for a strong core Java/Kotlin developer interested in bringing best practices to further the development of our Web3j library and tools.

As a developer on the Web3 Labs Engineering team, you will be responsible for all things needed to help progress the Web3j library, related tools, and documentation. It’s a hands-on role looking for developers who take pride in their work. You will work collaboratively with the rest of the team and community.

  • Experience with Git (Github, Bitbucket, or similar) - 3+ years

  • Experience with Gradle, Maven, Intellij and other related technologies - 2+ years

  • Proven interest in blockchain technology

  • Proven interest with using or working on Web3 libraries (ethers.js, truffle, web3js, web3j, ..)

  • Ability to work with an agile and remote team

Bonus
  • Hands-on experience with peer-to-peer and distributed systems

  • Hands-on experience with Solidity

  • Hands-on experience with Geth, Besu, or equivalent

  • Knowledge of the inner working of EVM or other blockchains

Why us?

At Web3 Labs, we pride ourselves on having an awesome culture. Don’t just take our word for it, here’s what our staff say:

“We have exposure to books and conferences. It's a cherished culture because blockchain is an area that continues to develop and so we need to keep up with all current developments.”

“It’s an easy going environment - easy to explore solutions independently and easy to speak out and share views. I have autonomy and receive constructive feedback in a positive atmosphere.”

“My job is extremely interesting. I’m surrounded by talented developers who focus on developing clean code and providing good solutions - it’s a true professional culture.”

We want to provide the optimal environment for our staff to work at their very best and understand that we also need to support their own personal needs. That’s why we provide flexibility on working days or hours to fit in with family commitments. We know that life has been pretty challenging for everyone lately and now our company works completely remotely. When life returns ‘normal’ we will meet up in person from time to time and continue to have our amazing team events when possible.

We want our staff to grow their own profile through the company too. We are supportive of OSS work and love it when our staff present at conferences and meetups like Devcon and ConsesSys’ Quorum Webinars. Of course, we sponsor our staff to attend and share their expertise at these events.

As we said above, since COVID-19 we've become a fully remote team. We’re happy to work with people based anywhere in a timezone that overlaps significantly with the UK (Europe, Africa).
