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.
Golang Developer ActiveState Vancouver, BC, Canada / Remote $40,000 to $100,000 a year
June 2019
1 Applicants This Week
More Than 6 Months Old
This job posting is no longer available
Job Description
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.
WHAT’S IN IT FOR YOU
Working for a stable and growing company that offers the environment and personal growth potential of a start-up.
The chance to work with a smart, passionate team of people.
The chance to work on a project that will change the work lives of developers around the world, including your own!
Competitive salary, bonus, and stock option plan.
Comprehensive benefits package and health/wellness credit program.
REQUIREMENTSÂ
Experience with Go.
The ability to quickly pick up new languages and technologies.
Experience with relational database (mysql, postgres, ..).
Basic knowledge of JavaScript and front end development.
Experience with all 3 major platforms (Linux, macOS, Windows).
The ability to write clean, well-tested code with clear documentation.
Excellent written and spoken skills, both technical and non-technical..
A willingness to engage in the process of defining our work through conversations with product management, other engineering teams, and the rest of the company.
The ability to help others on the team become better at their jobs through mentoring, thoughtful code reviews, and generally being a team player.
ASSETS
If you have experience with any of the following please make sure to highlight it in your cover letter:
TypeScript experience.
Javascript tooling such as Webpack and frameworks such as React and Redux.
Elm experience, especially large Single Page Apps.
Microservices and message queues.
Good working knowledge of Docker.
Experience building both web based and desktop based software.
Docker, Mesos, DCOS, Kubernetes.
Functional programming languages.
Experience Creating parsers, compilers or code intelligence systems
Deep understanding Process management on Windows or Unix environments
Work with reactive, event based systems
Low level architecture (sockets, primitive data types like in C) and the ability to interface and interact with low level libraries (e.g. debuggers).
We're looking for a Mid to Senior developer/DevOps (who knows Go preferably but not mandatory, it can be learned on the job).
Join us at Apperto (apperto.co), where we connect small to medium communities (less than 500k inhabitants) using cutting edge technologies. Many features, multiple communities, a single app.
We are a small company that just got funded and we want to expand our engineering team. Currently we have 9 people working full time but only 2 in engineering, so we want you to be the third!
You'll be working side by side with founders and first employees, learning all about our system, planning and executing improvements. On the backend we have microservices (all of them written in Go) running on Kubernetes and communicated using gRPC. On the frontend we have a mobile app written in Flutter that communicates with the backend using gRPC.
