Are you looking for a new challenge, do you love back-end development? When you hear the words Blockchain, Open-Source, Typescript, and Node.js, do you get all warm and fuzzy?

If you answered all of the above questions with YES, then you are in the right place.

The ARK Team is expanding its development department and wants you! If you are a back-end developer and want to be part of something unique and fresh, or maybe looking for a challenging and creative position, then this might just be the job for you.

We are looking for pure back-end developers who are not scared when they hear terms such as Byzantine Fault Tolerance, Finite-state machine, Schnorr signature, Elliptic-curve cryptography, Merkle tree, Bloom filters, WebSockets, Hash-Time Lock Contracts, etc… in short, to have an understanding of cryptography, distributed P2P networks and blockchain protocols.

We don’t discriminate in any way, shape or form. All we are looking for is someone prepared to work hard while respecting others, must beself-motivated, have knowledge of some of the terms above, enjoy working as a blockchain developer and above all else, willingness to learn and grow in the above-mentioned technology scope.

If you like to work on open source projects, love back-end development and want to be a part of a team that puts actual development before everything and doesn’t make promises they can’t keep, then being an ARK developer might be the job you were looking for.

We are looking for a long term, full-time collaboration and not seasonal or part-time workers.

What programming languages, tools, and other skills do I need to possess?

We are pursuing the Object-Oriented Approach (following SOLID design principles).

“Some skills are marked as optional (*), which means that we expect you to be proactive, think analytically and be willing to learn new technologies and developmental approaches/practices.”

Required Skills:

Language: TypeScript

TypeScript Engine: NodeJS

NodeJS Database: PostgreSQL via TypeORM

PostgreSQL via TypeORM Cryptography: ECDSA & Schnorr*; basic understanding of how to work with raw binary data, general data serialization/deserialization of objects

ECDSA & Schnorr*; basic understanding of how to work with raw binary data, general data serialization/deserialization of objects Networking: basic understanding of P2P networking and its protocols; our implementation uses SocketCluster* (WebSockets) library

basic understanding of P2P networking and its protocols; our implementation uses SocketCluster* (WebSockets) library Tools: Git, Docker*

Git, Docker* Testing: Jest*, CI, functional, integration, unit, … high coverage is expected for all new and existing code while keeping the tests descriptive and self-explanatory so that they can serve as documentation for new devs

Jest*, CI, functional, integration, unit, … high coverage is expected for all new and existing code while keeping the tests descriptive and self-explanatory so that they can serve as documentation for new devs SysAdmin: basic knowledge of server-based deployments* (Linux servers, NodeJS application installation) and console (CLI) part.

You will also need to be able to follow modern development standards and best practices. For example, coding standards (dependent on language), versioning standards, commit standards and test suites (if it isn’t tested it’s broken, right?).

You will also, need to be self-challenging and keep up with development from other developers in our team who are working on blockchain components.
