Senior Backend Developer - London
Coda is a technology company with a mission to build the best mobile games for each individual user with help of latest design trends and technology available for personalized experiences. Experimentation, creativity, and data are at the core of what we do.
We are a well-funded seed stage company founded by mobile industry veterans who have worked together for the past 6 years and exited their previous company. The company is based in London, and we have team members in Berlin and Istanbul.
About our team
We are a group of entrepreneurs who came together to build great games. After having exited the previous company that we built together and sold, our key goal is to make an impact in an area we are all passionate about and have fun.
We started and built the biggest mobile ad network in the Middle East and Southern Europe region and sold it to AdColony, one of the biggest, the inventors of rewarded video ads in mobile games. Our expertise is in the commercialization of games at scale, enabled by complex technology platforms.
Our goal is to bring together the best talent that is fit to go after our mission, regardless of background and location. We believe in opportunity equality and in the ability of diverse thinking teams to make a world-changing impact. We are looking to join up with other risk takers to form the foundation of our team.
We are looking for experienced backend engineers to build the Coda platform from scratch. You will be one of the pioneer engineers who contribute to all parts and elements of the data platform we are building, from infrastructure to architecture to development.
You will work in a team consisting of experienced backend, data and machine learning engineers, directly reporting to CTO, for designing and building an integrated platform with numerous components and services, the primary intention being recording, querying and processing data. Agility, speed, robustness, security and availability are the core properties of the system we are aiming for. Although there are particular technologies we would like you to be experienced with, the main acceptance criteria for this role are system thinking ability, perfect problem solving skills and desire for constant positive contribution to Coda’s success.
Why join Coda?
*You’ll get to benefit from being part of a transparent and early stage team where you can get exposure to various aspects of a company whilst deploying your own expertise with a clear product vision and the funding to survive the chasm * You will work on some of the hardest technical and operational challenges in the industry - explore and break your own limits and help us break our own * Yes it’s mission impossible and yes we know our ambitions are slightly over the top but we bring experience and resources of a proven team that has achieved a wild dream before and is hungry for more * You will work with a diverse team that has learning, having fun and achieving long term goals as top priorities

We are looking for a Golang developer who helps us develop an MVP for a nice Infrastructure as Code project. The MVP consists of a command-line application and a REST API for managing AWS cloud infrastructure in Golang. The project is running only for a few weeks, so you’ll have the opportunity to contribute a cool project right from the start!
We are developing the prototype of an innovative product for managing cloud infrastructure. It is all about running web applications in the AWS cloud in an easy-to-use, reliable, and automated way. Our users should be able to create and maintain the resources that they need without any external help. Behind the curtains, there is a framework that manages those resources in the AWS cloud with Terraform. This concept aligns with the Infrastructure-as-Code principle, which aims at providing documented and managed-like-source-code infrastructure definitions. We set a strong focus on economic factors, in that it should be viable to run both small and large applications and to scale those applications with high load and amount of users. The platform should be highly available and self-repairing – nobody should be on-call and responsible for fixing server deployments in the middle of the night. We have already validated a solution for creating and managing such an infrastructure, and we are in the process of bringing it to life.
The Task at Hand
The platform’s user interface is a command-line application which talks to the REST API, which we also develop. We want to implement these tools in Golang, and engineering has just started. We have a strong focus on software quality: in the end, we want to have a well-designed, robust software architecture with clear responsibilities and interfaces. The product should be automatically testable and maintainable for an extended period. An important factor will be integrating several data sources to deliver the right information to the user at the right time. The challenge lies in the heterogeneity and complexity of the data sources (for example, Terraform and AWS). It is also important to us that the product is intuitively usable: it should transform hosting infrastructure from a bothersome task to something fun. To achieve this, we want to gather user feedback and act on it iteratively.
You should have considerable experience with Golang and see yourself on an intermediate-to-senior level. In particular, you should engage with topics such as software architecture, testing on unit/integration/end-to-end level, and picking the right frameworks and libraries. You are also excited about clear software architecture and clean, well-maintainable code. We really care about this! ;) If you’ve got experience with infrastructure tools such as Terraform, Docker, Kubernetes, or cloud platforms such as AWS or Azure – that’s a plus, but we don’t expect you to know everything. And you won’t have to dive deep into all those topics (depending on your personal preferences, of course). There are more bonus points if you know how to integrate 3rd party CLI apps in a stable and reliable way.
You’re living in Berlin, Potsdam, or somewhere nearby, and you have one to two days per week to spare. The project is sponsored by a company for digital products in Münster (Zweitag). However, there is no need to travel there because you work together with a team member who lives in Berlin. The current project is projected to take six months. If it all works out fine, we can see you being invited to work with us for longer. 🙂

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.🔗 Link
