radio.net is an established startup with millions of users worldwide. For 10 years we have been the most successful radio app and website and now on the way to become the best podcast player. For this we need developers who want to find our product and our goals cool and want to move things in a great team.
You'll get a steep learning curve in our backend team with 4 senior developers. We work with agile methods and modern, automated release processes and a good work-life balance.
The day-to-day tasks mainly include designing new features, developing in Go, and integrating with our deployment pipeline with gilab and AWS CloudFormation. Your loyal fans are the front-end teams who are looking forward to any new or improved API endpoint.
We work according to the principle "you build it you run it". As we host on AWS, basically automating everything with CloudFormation and testing our releases very well, fortunately rarely gives a real problem and thus quiet nights.
You already have at least 2 years experience in software development with Java or Go and you are ready to develop yourself and your skills steadily. You've learned and sometimes used common best practices, design patterns and testing approaches.
Does that sound like a suitable challenge for you? Apply now via email to jobs@radio.net or directly via Stackoverflow and we will make a phone call in the next step.
About Herdius:
Herdius is a Berlin based Blockchain Company. We are working on building homomorphic distributed private key generation which then is turned into value bearing products in different sectors. Currently we are very close to open beta-testing for the Herdius-Crypto-Wallet.
What we focus on on the blockchain field specifically is interoperability and trading. When connecting different chains on the key level, users can eliminate communication channels, bridges and complex systems. In other words, users can do cross-exchange and chain token swaps very conveniently and profitably for the user due to the cross-exchange arbitrage opportunities. The broader vision is one day to replace API auth keys with public-private key cryptography in order to provide layered access to user data.
All this makes for a crypto eco system and hedge fund that pays interest on all cryptocurrencies (that right now are unfortunately somewhat unusable and just laying around on wallets).
About the role:

Herdius is seeking for a Gopher Guru - an experienced Senior Golang Backend-Developer - to join our team of smart and visionary individuals. Experience in Blockchain is not necessary but a big plus.
We do not look at this role as another standard job but rather as great opportunity to build something really meaningful und amazing. Become a member of our great collective of top nodge engineers and people - altogether working to create cutting edge tech for the masses.
Besides the Herdius HQ in Berlin our Dev-Team is working mostly remote on different time-zones - so this vacancy surely also is location agnostic.
We would expect you to contribute at least 20hrs per week for part-time but joining full time is possible, too.


Cool things you will work on:
Skills & requirements
Your education or professional experience at the end of the day does not matter to us. It all comes down to us being convinced by your skills and drive! 
We mainly look for people who are passionate about projects they work on and have the drive to see a project through. Our code is mostly done in Golang with some Solidity for connectivity with Ethereum.
How to apply:
Send anything that reflects on your knowledge and experience in the field. Besides a CV/LinkedIn-profile you can send links of your GitHub/Stack Overflow/Portfolio/ or something awesome you've built that you’re simply proud of.
