Job description

Hello. We’re Teya.

Teya was founded on a simple belief: local businesses deserve better.

They are the cafés, restaurants, salons, shops and entrepreneurs that bring character to our high streets, create jobs and keep communities moving. Yet for too long, financial services has made life harder for them - with clunky tools, poor support and complexity that gets in the way of running a business.

Teya exists to change that.

We’re building a financial platform for local businesses across Europe - one built around simple tools, thoughtful design and real human support. Our Members rely on us to help them run their business with confidence, and that responsibility shapes the way we work.

We move fast. We care about quality. We stay close to the detail. And we believe great performance and genuine hospitality should go hand in hand.

If you want to build meaningful products, solve real problems and make a genuine difference for local businesses, we’d love to hear from you

• Designing and optimising ETL/ELT pipelines to support scalable analytics and data products

• Collaborate with data analysts, analytics engineering and engineering teams to turn their data platform use cases into reliable production solutions

• Participate in the team's on-call rotation, investigate production incidents and contribute to improvements across Teya to prevent them from recurring.

• Participate in technical discussions and code reviews, contributing to maintainable designs and strong engineering standards

• Create and maintain clear technical documentation and operational runbooks

Your Story

• 5+ years experience in Data Engineering or Data Platform Engineering or Software Engineering working with Data

• Experience with ETL/ELT tooling (dbt, Airflow, Airbyte, dlt,..)

• Hands-on experience provisioning and managing cloud infrastructure with Terraform

• Experience with CI/CD pipelines, automated testing and Git-based development workflows

• Familiarity with observability practices, including logging, metrics, alerting and production troubleshooting.

• Strong grasp of software engineering principles and best practices

• Experience contributing to or leading data warehouse architecture or redesign initiatives

• Ability to collaborate effectively with technical and non-technical stakeholders

• Strong experience with data warehousing, dimensional modelling, and data architecture
