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.
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.

We have multiple openings for senior software engineers in our brand new London office. These are in a range of teams including fraud, platform, payments, shield, onboarding, and crypto-security. With over 40 engineers based in our Cape Town office, you’ll be joining a group of highly motivated experienced developers who you’ll work collaboratively with across our currency exchange, fraud, payments and compliance pods.
As a small company operating on a global scale, you’ll immediately see how your contributions directly impact both our internal users and client experience. We make decisions based on facts, not fiction. Many of the problems we’re solving result in genuinely trail blazing solutions which can’t be found on StackOverflow; so we’re looking for an experienced engineer that thrives on working in a complex domain.
We use Go, microservices architecture (gRPC) and AWS, but if you come from a Java, Python or other relevant language we’ll help you get up to speed with our comprehensive engineering onboarding program.
We succeed as a team. Our teams are split into pods, each of which focuses on a specific aspect of our product. Any engineer is able to deploy to production, and we deploy multiple times each day. Your pod will include a product owner, back end engineers, Android and iOS developers, and web developers who each bring a unique perspective to the problem you’re all solving.

We provide great benefits and the autonomy to conceive and execute your own projects. Best of all you get to work with a diverse team of talented, ambitious and friendly people on something that will truly revolutionise the world.
As a “Newnaut” we’ll fly you to Cape Town to meet the wider team, and go through our comprehensive onboarding program. We expect you to have a passion for blockchain and cryptocurrencies but we understand that this is a new industry so we’ll help you learn about how the blockchain works and understand all aspects of our business.

Distributed Systems Engineer - to help us build a public, decentralised, blockchain-backed legal agreements network
London
£40,000 - £80,000 plus options (ESOP).
Relocation package available for the right candidate. This role could also be based in our Edinburgh office.
Candidates currently based outside of London or Edinburgh must indicate their preferred location and willingness to relocate in their cover letter.
We are looking for kind, talented software engineers to help us make smart iterations on our legal agreements network as we deploy successive test networks.
Monax were pioneers of permissioned blockchains and smart contracts and we are building our Agreements Network to allow new and more efficient forms of legal transacting.
Exploiting the benefits of various decentralised, distributed, and masterless technologies - chiefly Hyperledger Burrow, which Monax built from scratch and still maintains based on the Tendermint consensus engine.
You will have the chance to work on a system that has distributed consensus and validation in a low trust environment at its heart and offers very interesting challenges, these could be:
Working with our CTO on our Node Distribution Team you can expect to quickly own significant parts of our stack, and make decisions that will affect the company’s future viability in a fast-moving space (public permissioned consensus networks). You would also work closely with our Product Team who are responsible for building the foundational smart contracts, the business process modelling engine that drives the Agreements Network and also our particular front end (the network is open to extension by any of our co-founders however).
Your role will give you the chance to work across all teams in the business and it will also give you the opportunity to leave your mark in a growing industry, where you need to evaluate existing best practices and apply them to new technological paradigms and new programming languages. Navigating between the hype, the detractors and the zealots we believe there is real value in our approach and we intend to prove it.
You will join a business building a genuinely novel system, that in part intends to create an entirely new market by enabling legal products that challenge existing legal services.
This role would suit a talented software engineer, with solid technical skills in and a minimum of 3-4 years of software development experience. We are also open to engineers who can bring significantly more experience to the role. If you are a good match for Monax, we are willing to create a role that suits you.
Who do we need? Someone who has:
It is crucial that you are able to take part in forceful yet respectful technical discussions with colleagues and that you are able to change your mind about something if required, and also are able to change other’s minds.
Real things you might work on:
What can Monax offer you?
Extremely marketable blockchain and cryptocurrency skills.
The chance to make blockchain systems live up to their hype by making them highly operable, our network will be operated peer-to-peer by many parties and this needs to be as painless as possible.
Experience in blending distributed, decentralised, and centralised systems. To spend time working on something foundational at the level of a network architecture.
The chance to spend time thinking ‘around the software’; about law, economics, and game theory.
You will have a high level of autonomy. The business has just enough hierarchy, consensus and individual project responsibility (c.f. design-by-committee) favoured over diktats.
Flexible working - the successful candidate will be based in our London or Edinburgh work space primarily, but there is scope for flexible working and choosing your own hours and place of work when established.
Relocation assistance is available for the right candidate.
Who will you be working with?
Around fifteen people in our passionate cross functional team, including time with:
