Data Engineer - Technical Intelligence

Who are we?

IOG, is a technology company focused on Blockchain research and development. We are renowned for our scientific approach to blockchain development, emphasizing peer-reviewed research and formal methods to ensure security, scalability, and sustainability. Our projects include decentralized finance (DeFi), governance, and identity management, aiming to advance the capabilities and adoption of blockchain technology globally.

We invest in the unknown, applying our curiosity and desire for positive change to everything we do. By fueling creativity, innovation, and progress within our teams, our products and services are designed for people to be fearless, to be changemakers.

What the role involves:

As a Data Engineer, you are part of the Technical Intelligence (TechInt) team. The team’s main function is to recon the blockchain industry and feed the company with new trends and projects. The TechInt team has automatized the recon process by utilizing a data lake and machine learning. The team currently harvests data from a variety of different sources. This data gets fed into different systems that then show this data as a report.

You are responsible for maintaining and setting up data solutions and services. A key part would be to aid in the maturation of the data ingestion pipeline and processes. Moreover, you would be expected to create a state-of-the-art data warehouse which would be cloud-native. In your daily job, you do a mix of data engineering, and cloud infrastructure management.

• Develop and maintain automated data ingestion (API or crawling) pipelines from source code repositories, social media, and on-chain analytics.
• Simplify existing data pipelines - re-architecting where necessary.
• Research existing datasets to figure out their relevance - and remove irrelevant data pipelines and sources.
• Design a data warehouse that can be queried by analysts and APIs, and that will serve as a data backend for a reporting web application.
• Collaborate with data scientists to operationalize ML models and deploy them into production environments.
• Work closely with leadership to understand and define requirements, ensuring alignment with the department’s strategy and roadmap.
• Collaborate with a Data Scientist and an Intelligence Engineer to implement technical solutions that meet project goals.
• Ensure systems are functional, available, and carefully monitored for continuous performance and reliability.

Requirements

Who you are:

• Minimum 3–4 years of hands-on recent experience with AWS cloud services :
• Knowledge of Infrastructure as code (such as Terraform, AWS CloudFormation, Python AWS CDK).
• Knowledge of cloud services management in AWS (such as S3, Redshift, Lambda, Batch, Glue, Athena etc.).
• Hands-on experience with Docker for containerizing data applications.
• Knowledge of relational databases and writing highly optimized SQL, including data transformations, complex joins, and performance tuning.
• Strong proficiency in Python programming, including PySpark for data transformation.
• Ability to communicate well both verbally and in writing, with both technical and non-technical partners. Professional English.

It would be beneficial if you have the following:

• BSc/MSc in a Computer Science field, or equivalent practical experience.
• Knowledge of big data processing platforms (such Databricks) and data manipulation libraries in Python (such as Pandas, Polars).
• Knowledge of docker container orchestration (such as Kubernetes, ECS).
• Knowledge of Continuous Integration and Continuous Delivery (CI/CD) pipelines (such as GitHub Actions, Travis, Jenkins).
• Knowledge of blockchain on-chain data representation.

Are you an IOGer?

Do you find yourself questioning the status quo? Do you tinker with ideas and long to turn those ideas into solutions? Are you able to spark thoughtful debates, bringing out the inquisitiveness in others? Does the promise of continuously growing excite you? Then get ready to reimagine everything you thought wasn’t possible because that’s what it means to be an IOGer - we don’t set limits, we break them.

Benefits

• Remote work

• Laptop reimbursement
• New starter package to buy hardware essentials (headphones, monitor, etc)
• Learning Development opportunities
• Competitive PTO
