We are looking for smart, dedicated and If you If you know Linux inside out, and if you are a software development expert, then we need to talk. We are looking for smart, dedicated and experienced Software Engineers to join Codenotary. You will become part of our experienced team developing modular command line applications using the latest technologies. On a daily basis you will work with Docker, Kubernetes, and others.

Codenotary is the leading company for trusted software supply chain. We bring trust and integrity into the DevOps process by providing end-to-end cryptographically verifiable tracking and provenance for all artifacts, actions, and dependencies.
Our solution can be used on-premise or in the cloud, is always easy to use and can process millions of transactions a second with cryptographic verification of no-tampering. The core engine of Codenotary Cloud® is immudb, the open source standard for immutable databases.

Responsibilities

  • improve capabilities of our CLI tools for creating and tracking artifacts, with special focus on Kubernetes, vulnerability scanning and runtime detection
  • modularize CLI tool architecture so it is plugin based and selected features can be easily enabled/disabled, or even developed by third parties (open source)
  • improve APIs and a way how CLI tools communicate with backend
  • performance and stability improvement. CLI tools are used in CI pipelines and they need to be reliable and fast.

Qualifications

  • Good knowledge of English (spoken/written)
  • Master’s degree in Computer Science or EE
  • 10+ years of professional experience in developing software products
  • Expert level programming skills in one or more of the following languages: Go, C, C++, Java, Python
  • At least one year of experience developing in Go
  • Experience in working with databases or key-value Stores (e. g. Redis, MongoDB, Dgraph)
  • Experience developing API driven architectures (e.g. REST, gRPC)
  • Outstanding knowledge of Linux and Kubernetes
  • Experience developing CLI tools
  • Great team skills

Please note that the technical skills will be tested in 30 minutes of coding tasks with shared screen.

Use Case - Tamper-resistant Clinical Trials

Goal:

Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).

Implementation:

immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance

Goal:

Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.

Implementation:

While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace

Goal:

No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


Implementation:

immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data

Goal:

IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.

Implementation:

immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence

Goal:

CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.

Implementation:

As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
