*Are you looking for a career in a leading blockchain technology company? *

Web3 Labs works with both small and large companies, helping them to succeed with their blockchain deployments. The companies we’ve worked with have been able to simplify their business processes by harnessing the new trust and transparency models that blockchain technology provides. Our clients include Microsoft, J.P. Morgan, Vodafone, ConsenSys and R3.

We also author an open source blockchain library Web3j, which has been downloaded nearly 1 million times, and our Epirus Blockchain Explorer is widely used by enterprises for reporting and supporting their blockchain deployments.

Web3 Labs are recognised for the first class services we provide and we were proud to be a runner up in Microsoft’s Partner of the Year Awards, 2020.

Life at Web3 Labs

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).
