BI Engineer

Pracovní nabídka

Do you enjoy making sense of data and building the data infrastructure that drives company-wide decision-making? Would you like to help build a new SaaS product from the ground up?

We’re looking for a BI Engineer to join the Phonexia Voice Guardian team. Voice Guardian is our new cloud-based platform for voice biometrics and fraud prevention in bank contact centers.

Your Role

As a BI Engineer, you will be responsible for:

• Designing, building, and managing the data solution for the Voice Guardian platform,

• collecting and processing product, billing, and performance data,

• preparing data for reporting and visualization, including dashboards for Product, Engineering, and Sales,

• integrating and exporting data to customers’ and partners’ systems,

• ensuring data quality, consistency, and auditability, especially for billing,

• gradually expanding the data solution to connect Product, Sales, Marketing, and Finance.

Skills You Will Need

To excel in this role, you should be proficient in:

• Experience designing data solutions, including dimensional modeling (Kimball, star/snowflake schema) or Data Vault. You understand when different approaches make sense

• Strong knowledge of databases, including relational and document databases and their trade-offs.

• Experience with data tools and orchestration, such as dbt, Airflow, Dagster, or similar.

• Python skills for data processing, automation, and integrations.

• Experience with cloud data services. We use AWS, so experience with S3, Athena, Glue, Redshift, or Aurora is a plus. Experience with another cloud platform is also welcome.

• A strong focus on data quality and accuracy — especially when it comes to billing, where every cent matters.

• Good English communication skills, including the ability to write documentation and communicate with international colleagues and customers.

Nice to have:

• Experience with streaming data and Kafka,

• experience building and maintaining ETL/ELT pipelines,

• knowledge of BI and data visualization tools such as Power BI, Tableau, Looker, Superset, or QuickSight,

• experience with lakehouse technologies and data formats, such as Parquet, Iceberg, or Delta Lake,

• experience with data observability or usage-based billing in SaaS,

• experience integrating CRM, marketing, or financial data,

• understanding of data privacy and security, including GDPR and multi-tenant environments.

What Makes This Role Unique?

You won’t be maintaining legacy reports. You’ll design the Voice Guardian data layer from the ground up and have a real say in how it is built.

You’ll work in a small, experienced team where your work has a visible impact on billing, platform performance, and the future of the product.
