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.âšWhat 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:
âšHerdius 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.âšâš
Cool things you will work on:
Implementation and design of Herdiusâ 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! âšWe 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 youâre simply proud of.

Job Description
We created Jodel to let you instantly connect, share, and engage with the community around you. We built thriving local communities across Europe and continue to expand globally. With over 1 million users creating more than 6 million posts per day, we have one of the industry's highest retention rates. We've attracted great investors such as Christophe Maire, Adam dâAngelo, and the Floodgate Fund, and even been the subject of several academic papers.
We're growing our Engineering team around a culture of sustainability and empowerment. We're dealing with dynamics such as being local, signup-lean and many more, which give us new problems to solve -- weâre literally breaking new ground in the Social Network space. Data-driven by default, with a bias for quality and code sustainability, and fostering a solid DevOps and Automated Testing culture, Jodel's Engineering team is the place to be!
Attitude we're looking for
* Youâre naturally motivated and proud of doing great work;
* Numbers and data are the best way to drive your decisions;
* You have a strong personality, sense of ownership and responsibility;
* You put people and human interactions above processes and rules;
* You understand the value of "measure twice - cut once" and you work by this mantra;
* You own your successes and your failures, and constantly seek to improve;
* You keep your mind on the product we're building, and are permanently aware of how each small action influences its success.
What we value
* Your studies were in Computer Science, Mathematics or Engineering;
* You're a problem solver, and youâre eager to experiment and learn new things;
* You write code optimizing for clarity and readability;
* You value testing very highly;
* You write software aiming at reducing the cost of change;
* You enjoy pair programming and code reviews, and see your job as a collaborative effort rather than solitary work;
* Engineering work is mostly about compromises and so you're always open to discuss different approaches to problems;
* You're happy to collaborate with your community and industry, either in open source projects or presenting at meetups and conferences;
Skills we're looking for
* You have experience with either Node.js or Golang, but you're definitely interested in doing more Golang as part of your job;
* You want to work in Distributed Systems;
* You have experience with MongoDB and Redis, beyond "I have played with it in the past";
* You have a bias to automate things when possible;
* Youâre ready to embrace a DevOps culture, because an Engineerâs work doesnât end after we âgit pushâ;
* You're ready to work with Linux, Cloud providers, Docker, Kubernetes
What do we offer?
* An Empowered Team -- Engineering owns tech debt and tech improvement decisions; we collaborate tightly with our product team but we're all very mindful not to step on each other's toes. We own technical decisions, take responsibility and are accountable for them..
* Preventive culture, rather than reactive -- While some of us participate in on call duties, we have a very low amount of actual production emergencies. A lot of energy goes into fixing root causes and we are very proud of not having anyone in firefighting mode.
* Career building is part of the deal -- you don't join to just write tests and contribute to the product - you also join to improve your career. We pay special attention to your personal development and make sure you're focusing on the skills that matter the most to you.
* Lean processes -- we try hard to cut meetings and processes to a minimum, to ensure that youâre being productive. And we encourage all interactions to be direct and open, not forcing you to go through any intermediaries to get your work done.
* United in diversity -- with people from all over the world, from Tunisia to France, from India to the Poland, we are multicultural by default and proud to be so. We all come from different walks of life and cultural backgrounds, and we continue to push for diversity in our team!
* We're building a team, not just making money -- we solve hard problems together but we also relax and have fun. From team cooking to going on company trips, from office parties to go-karting, we'll make sure you have a good work-life balance.
* The future will be amazing -- the list of non-trivial challenges we'll be dealing with includes developer APIs, security issues, scaling access to a lot of data (among other things we can't tell you about :-) ); all of this with location and anonymity as their own dimensions in Jodel.
* No one else is doing what we're doing -- it's that simple. We're pioneering local communication and since communication is a basic human need, our work is super exciting. On top of that, we are one of the few large scale European Social Networks. Thereâs not that many and we're very proud to be "Made in Europe".

Golang Engineer Lightmeter Berlin, Germany $40,000 to $50,000 a year
December 2020
1 Applicants This Week
More Than 6 Months Old
This job posting is no longer available
Job Description
Please note: this position is full time and in Berlin (you need to already be in Berlin too). We don't use agencies.
Most messaging networks are created to serve their creators. Email is designed to serve humankind. For over 50 years inspired technicians have architected email to provide the greatest good to the greatest number. Their openness and design principles made email the world's #1 communication channel and identity provider with 4.2 billion users (2x Facebook). Email is a critical foundation stone of the Web.
Lightmeter is reinventing email infrastructure to overcome threats from centralised tech oligharchs like Microsoft and Google. An epic platform war is behind fought behind the scenes to wrestle control over digital comms and incorporate it into closed service platforms, where the customer is a product to be sold to the highest bidder.
We are 3 years of research and 1 year of development in to building Lightmeter Control Center - the all-in-one mailops management system repeatedly featured in Heise and ZDnet. It's fully Open Source (on GitLab) -- feel free to check the unit and user acceptance test code coverage : ) . Our engineering team has a background in embedded and fintech, with a focus on performance and feedback.
A mix of public and private funding fuels our work, and we've been recognised by the European Commission as part of 'Next Generation Internet'. We have hundreds of active users, a few of whom we interview each week, including banks, public universities, Internet Service Providers, and marketing agencies.
Our mission is to strengthen the foundations of digital society by making mailtech easy and convenient.
Thatâs a brief intro to what youâll be working on. But first, you need to know if youâll even like working with us. Letâs talk about life at Lightmeter and then weâll go into detail about what weâre looking for.
Who youâll be working with
One luxuary of being an early-stage team is that you get to work directly with everyone. That said, you'll be reporting to Sam, our CEO. He gets easily excited about engineering patterns and workflows, and likes bright colours and house music with vocals.
You'd work along-side Lead Developer Leandro, who calls himself a Software Craftsman, and who others call a philosopher. Leandro has deeply held unfashionable beliefs like "all code should be fast and light", and cares more about design patterns than what language he's coding in. He love the outdoors and pines for the mountains.
Suela is our Product Manager and x-ray seer of quality and value. She has a nack of turning our telescopes around, pointing out better perspectives, opportunities, and efficiencies. She's an Open Source fangirl, community organiser of the OpenLabs Hackerspace, and secretly learning Python so she can make bots to replace herself. Just kidding!
How Youâll Work at Lightmeter
We work hard to make working here a great experience, and have a team of truly exceptional people â the kind youâll be excited to work with. You'll get to design and create new components and services, working on features like those on our roadmap (https://lightmeter.io/roadmap).
Hereâs how we operate
No Crazy Hours
You'll very rarely work more than 40 hours per week, unless you really want to. Ocassionally things can heat up, but noones going to force you to work more than is comfortable. When you do work overtime you balance it out with time off afterwards. We work hard and smart, planning carefully, but weâre in this for the long haul: sustainability trumps anything short term.
Face time and alone time
Most of us have worked fully remote before and miss the benefits of face time, so we like to work together a lot of the time. However focused time alone, in cafes or home-office is nice too, so we aim for a good mix. So long as you can reach the people you need, when you need them, and vice versa, your preferences for office vs remote work shouldn't be an issue.
Take Vacation
A small team means it's easy to coordinate time off to relax and recharge. Notice you'll be away a week in advance is usually enough.
Up Your Game
Weâre serious about helping you improve your craft. Everyone wins when you get better and your job, and enjoy the process. Think conferences, online courses and subscriptions, dedicated time away from work to learn something new.
Compensation and Legal
We can't currently offer you a salary to compete with Amazon or Microsoft. What we can offer you is the same salary that we are paying ourselves: âŹ50,000 / year.
Weâre an early-stage startup, funded, pre-revenue, and growing. We are owned and managed by our Founders. Making sustainable, profitable products with a committment to openness is hard; we're demonstrating how it's done. If you care deeply about digital freedom, empowerment, and collaboration, you'll probably fit right in!
What we're looking for
Lightmeter has ambitious goals and our team is growing to meet them. You're the Software Engineer we're looking for if you're collaborative, mission-motivated, creative, disciplined, and productive. (So far, so good?)
You love solving complex problems â both internally and for your users â and know what it means to build a mature, evolving product. You are more focused on the outcome than on the output of your work, and prefer to deliver something useful sooner, rather than something perfect later. You welcome feedback, and are curious about users' challenges and how to address them. You demand a lot from your colleagues and expect the same in return, taking personal pride in collective achievement.
Requirements (these are real, actual requirements)
You must live in Berlin most of the time, so we can meet up and work together sometimes
You must have at least five years working in the software industry, of which at least four are as a software engineer.
You must have experience working in cross-functional teams. And we really mean that cross-functional part â in other words working directly with designers, quality assurance, product managers, or other related roles.
