Trustory is a decentralized social network to validate claims that people make.
THE PROBLEM
The internet is a place where anyone can tell their stories and be heard. Yet, in being open and permissionless, the internet sacrifices trust. If you really want the truth, you have to read credible sources, cross-reference them, and remove the bias. See the problem?
OUR SOLUTION
We’re building a decentralized application on top of the internet that doesn’t sacrifice trust or convenience, to get the truth. Using game-theoretic incentives, it’s possible to create a social network that validates the truthfulness of information.
WHAT WE VALUE
We value ethical, curious, and passionate people.
We don't care about your grades. We don't care about your pedigree. We care about your intellectual tenacity. We care about how you think not what you think.

How would you steam live audio traffic across multiple services into a machine learning model? What is the memory consumption of a service streaming data with maximum network utilization? How would you handle images send to a GraphQL endpoint?
At Corti, we have proven a life saving technology that augments emergency medical dispatchers with machine learning. We envision a near future where all emergency dispatchers around the globe are augmented by our intelligence. We are proud to say that the engineers at Corti are saving lives. A life saving engineer is dedicated, seeks for real purpose and is proud to the extent of obsession. We don't need the ninjas and wizards, we need people who own every aspect of their work at any time.
To get there, we need to solve problems that go way beyond picking the right text editor. The engineering team at Corti owns the entire stack, from live audio capture, real time traffic processing and classification using machine learning models to the hardware on the dispatcher desk, the servers in the basement and the right cloud strategy.
We pick our team members carefully so we can maintain our culture of excellence. We look for complementing skills and characters and care less about your degree, certifications and experience. You can't hide behind your screen as we are a team that believes in collaboration across all the departments at Corti.
You can solve problems and you can proof it to us. You are better at estimating memory usage than remembering the exact implementation of quicksort. A new problem stimulates your creativity rather than your hippocampus. Working cross domain is a bonus for you and you are eager to widen your horizon.
While we have a core set of tools, programming languages and concepts we work with, we will definitely going to ask you to learn something new. Never worked with machine learning? This will change. Writing a parser for a network protocol? It will happen. Transitioning a customer to the cloud? The sky isn't the limit for us.
We are looking for someone experienced in Golang to support our backend team. You would be mostly working on the REST and GraphQL API and the integration with the models from the machine learning team.

Swarm is a system of peer-to-peer networked nodes for a decentralized storage and communication service.
Swarm could shape the future towards a self-sovereign global society and permissionless open markets. On Swarm, applications run autonomously yet securely in a planetary-scale deployment and execution environment.
Bee is a Swarm client implemented in Go. It’s the basic building block for the Swarm Network. Bee provides low level constructs for file storage, feeds, key-value stores and untraceable communication, through solid, well-tested code delivered in an agile manner.
Key technologies are Go, libp2p, protobuf, leveldb, and go-ethereum, as well as various cryptographic libraries.
Your role: This role expects the candidate to function as a large node operator, conducting testing and immersing themselves in the responsibilities of node operators. This requires experience in a comparable QA position, as well as an interest in DevOps-related areas. However, we consider motivation and initiative-taking to be the most crucial qualities that the ideal candidate should possess.
The responsibilities of the role: Writing and executing end-to-end test scenarios on testnet and mainnet in order to assure performance and reliability. Submit detailed bug reports and issues to our developers' team. Give the green light to the developers' team to proceed with a release. Be an active part in shaping the way our products are built by analyzing how functionality, user experience and performance could be improved.
This role is an excellent opportunity, as in the future we expect the QA team to grow and therefore this role could open the possibility of becoming the QA team lead.
Your profile: * You have at least 3 years of hands-on experience in a similar position. * Solid understanding of distributed systems * Experience in executing manual and automated tests interacting with the API. * Be able to set up different environments to perform automated testing on them. * You are familiar with the blockchain ecosystem. * Experience in managing panels and dashboards for monitoring, * Familiarity with Ethereum is a must. * You can express yourself fluently in English, both verbally and in writing. * You manage your own time effectively and respect time constraints. * You like to take initiative. * You are available around CET timezone.
