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

This includes every stage of an ELT process, both at the pipeline level and the underlying infrastructure as well as working with engineering teams on how to best leverage our data..

As a senior member of the Data Engineering team, you will contribute to platform architecture, data product thinking, and engineering best practices, helping build a world-class scalable Data Platform that enables both analytics and future AI capabilities.

We want you to wonder about centralized vs decentralized provisioning of data tools, the trade-off between complex governance systems vs ease-of-use and data democratization, how to create simple processes to manage all the phases of the Data lifecycle and how to have some fun while doing it.

Your main responsibilities will include:

• Designing and evolving the architecture of our data infrastructure

• Maintaining the existing data platform

• Ensuring the reliability of our data ingestion pipelines

• Propagating learnings in the Data Engineering team to other parts of Teya

• Guaranteeing proper data governance following best practices, while not adding 100 steps of bureaucracy

• Improving data reliability, quality, and observability across key datasets, while ensuring data pipelines are simple to set up.

• Building, maintaining, and improving data models for large and complex datasets, while ensuring they have a simple lifecycle

• 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

• Strong SQL expertise, particularly in complex analytical and warehouse queries

• Proficiency in Python and/or Java

• Experience with Data Warehouses, such as Snowflake or Apache Iceberg

• Practical knowledge deploying and operating containerised workloads using Docker and Kubernetes

• Knowledge of streaming tooling (Kafka, Kafka Connect, Flink,…)

• 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
