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:
Implementation and design of Herdius’ consensus algorithm and p2p order routing protocol.
Lots of work around trading and high volume data handling and transfer.
Design and implementation of a low-latency, high-availability, and performant algorithmic hedge fund and exchange order book.
Integration of the Herdius distributed private key generation protocol.
Constant performance testing and improvement of our architecture.
Working on new financial products that have not been seen in the crypto world, setting up the base-layer infrastructure of a trading system and hedge fund
Skills & requirements
Strong proficiency & experience working with Golang
3+ years of experience as a backend engineer, language agnostic but Go, React, NodeJS, Vue.JS, Scala, Angular, Rust preferred
Experience and passion working with distributed systems and networking
Strong interest in blockchains and related technologies
Passion for delivering quality, secure code with loads of testing
User authentication and authorization between multiple systems, servers, and environments
Interest in privacy and cryptography, trading and financial service
Understanding fundamental design principles behind various consensus algorithms
Understanding differences between dPOS, DAGs, Plasma, BFT, aBFT, etc.
Implementing automated testing platforms and unit tests
Proficient understanding of code versioning tools, such as Git
Interview Process
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.
How do you design and implement an API that communicates with thousands of cash registers in all stores of REWE, Penny and real,-? How do you automatically transfer money between different banks?

At Barzahlen we operate Germany's largest independent payment infrastructure. Customers can use different services in several supermarkets to e.g. pay their invoices and deposit or withdraw cash from their private bank accounts using smartphone apps.
In order to further develop our systems and to implement new projects we are looking for software engineers. It is important for us that the following applies to you:
You love coding! Software development is not just a job for you. You are coding on private projects as well and you are interested in the latest developments in the industry. You are fluent in at least one programming language.

You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, over to our internal services and the PostgreSQL database. It’s your aspiration to ensure an error free operation of all our production systems through a mixture of code reviews, unit + integration tests and monitoring.
High requirements merit appropriate compensation. We are competing with other companies for your time and knowledge. So why should you decide to join us?

We have experts in the IT as well as in all other departments with excellent connections to other companies throughout Berlin and Germany. You can learn a lot of new things and experience how to build a "FinTech-Startup" from the ground up and to establish it in the market.
After creating a solid base of operations in Germany over the last 4 years we plan to realize several large projects in the coming months which build upon our existing payment infrastructure.
We will be happy to tell you more about this in a personal chat :)
