• Evaluate and integrate new data technologies and tools to enhance the capabilities and efficiency of the data platform.

What you’ll bring to the table• Experience: At least 7 years of experience in data engineering, with a strong emphasis on developing data platforms, data modeling, and managing data assets.

• Data Platform Expertise: In-depth, hands-on experience with technologies for data ingestion, job orchestration, data warehousing, and reporting.

• ETL/ELT: Proven ability to design, implement, and manage robust ETL/ELT pipelines using various tools (e.g., Spark, dbt).

Bonus Points

• Experience in the financial services or FinTech industry, specifically with cross-border payments.

• End-to-end experience building data platforms, connecting all components from ingestion to reporting, using industry-standard tools. These include: Fivetran (ingestion), Databricks (lakehouse), Astronomer/Apache Airflow (orchestration), and Metaplane/Datadog (observability).

• Proficiency in data modeling tools and techniques (e.g. dbt).

• Familiarity with modern data lake formats such as Delta Lake and Iceberg.

• Experience with real-time data processing and streaming technologies (e.g. Flink, Epsio).

AI Literacy & Tools As Zepz continues to build AI into how we work, we expect everyone to engage with it as a core part of their role. For this position we are looking for:

• A genuine curiosity about AI and how it can be applied in your area of work — from accelerating analysis and insight generation, to improving how we design and deliver processes and communications.
• Practical experience using AI tools in a professional context — whether to connect information, draft content, build frameworks, or create insights from data. We want people who actively use AI to increase productivity, not those who are waiting to be told to.
• Strong AI literacy — an understanding of what AI assistants can and cannot do, how to prompt effectively, and how to critically evaluate AI-generated output before using it.
• Awareness of the ethical considerations and responsible use of AI in the workplace, particularly in the context of sensitive data, customer experience, and compliance.
• Prior experience using Claude (Anthropic) is a nice-to-have but not essential — what matters most is that you are genuinely engaged with AI as a tool, comfortable experimenting, and eager to share what works with your wider team
