QA Engineer (Go, blockchain, distributed system)
Swarm is a system of peer-to-peer networked nodes for a decentralized storage and communication service.
Swarm could shape the future towards a self-sovereign global society and permissionless open markets. On Swarm, applications run autonomously yet securely in a planetary-scale deployment and execution environment.
Bee is a Swarm client implemented in Go. It’s the basic building block for the Swarm Network. Bee provides low level constructs for file storage, feeds, key-value stores and untraceable communication, through solid, well-tested code delivered in an agile manner.
Key technologies are Go, libp2p, protobuf, leveldb, and go-ethereum, as well as various cryptographic libraries.
Your role: This role expects the candidate to function as a large node operator, conducting testing and immersing themselves in the responsibilities of node operators. This requires experience in a comparable QA position, as well as an interest in DevOps-related areas. However, we consider motivation and initiative-taking to be the most crucial qualities that the ideal candidate should possess.
The responsibilities of the role: Writing and executing end-to-end test scenarios on testnet and mainnet in order to assure performance and reliability. Submit detailed bug reports and issues to our developers' team. Give the green light to the developers' team to proceed with a release. Be an active part in shaping the way our products are built by analyzing how functionality, user experience and performance could be improved.
This role is an excellent opportunity, as in the future we expect the QA team to grow and therefore this role could open the possibility of becoming the QA team lead.

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.
