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.

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!

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.

Are you a Golang developer that’s passionate about developer tooling? ActiveState is looking for developers to level up their end-user tooling team. This team is mainly responsible for “the State Tool”, a new command line tool we’re developing that allows you to quickly jump-start runtime environments for your projects. Backed by ActiveState’s new platform we’ll be able to provide developer tooling unlike any you’ve seen before.
If you know Python, Perl, or Tcl you've probably heard of ActiveState's language distros. Now we’re building an ambitious language distribution platform and set of tools so that coders can focus on coding and spend less time worrying about dependency hell, third party vulnerabilities, and inconsistent developer environments. We’re doing this for every language and platform on the planet (and beyond). We need your help to do it! Best of all you’ll be working on a product that you’ll use yourself daily.
This position is based out of our headquarters in beautiful Vancouver, BC. Remote work will be considered, but only for candidates in North America.
WHAT YOU’LL BE DOING
Your job is to help us build the tools that take the pain out of developing code in teams. Our lofty goal is to replace the venerable README file with a single command. You’ll work on command line clients, editor tooling, and more. While a primary amount of your job will be described as back-end work you must be comfortable with a little front-end work as well.
When not working on code, you’ll be meeting with your team to figure out priorities, features, technical issues, etc. You’re someone with good technical knowledge who also has an interest in the end-product you’ll be building.
Our day to day work practices are centered around GitHub, pull requests, code review, CI for testing, and agile development with Pivotal Tracker as our project management tool. We’re always looking to improve our practices and we expect you to help us to do so.
We’re a polyglot company and embrace using the best language for the given task at hand. You’ll regularly find Golang, Elm, Javascript, Python, Docker, Kubernetes, DCOS, CircleCI, and other modern tools. Quality is as important as speed. We’re building for the long run, so you’ll need to be proficient in writing tests and documentation too.
Our back ends and command line tools for interacting with our Platform are written in Go. While certain extended components of the platform that you might interact with from time to time are written in Elm and Python. We’re also aiming to get a foothold in TypeScript for future editor plugin work.
The team is scattered around the US and Canada, so we coordinate with each other and the rest of the company using Slack for chat, Highfive for video calls and screen sharing, Pivotal Tracker, and the Google Suite.
We like to use open source software whenever possible, and we also like to contribute back to the open source ecosystem. We embrace open sourcing both libraries and tools developed in-house as long as those are not mission-critical code.
