Job Description
This role sits within our Data and Technology team.
In this role, you will own and extend our config-driven data platform (DMI), which standardises ingestion, transformation, and delivery of paid media data across 26+ ad platforms for multiple global clients. You will work closely with our team to build and maintain ELT pipelines from Cloud Function ingestion into BigQuery through to dbt-powered transformation ensuring the highest standard in data integrity and scalability.
This is an exciting role with excellent career opportunities within a high-profile team and scope to strategically shape the agency. We are looking for someone who can hit the ground running, contribute to a mature mono-repo data platform, and help drive best practices across the engineering team. Experience with digital media data is highly beneficial.
Responsibilities
- Own and extend the end-to-end data pipeline from Cloud Function ingestion through dbt transformation (staging → intermediate → marts) to analysis-ready tables in BigQuery.
- Develop and maintain dbt macros, Jinja templates, and platform YAML definitions that auto-generate models across 26+ ad platforms.
- Manage and improve GCP infrastructure (BigQuery, Cloud Run, Cloud Functions, Cloud Scheduler, Pub/Sub) provisioned via Terraform.
- Build and maintain the Python CLI tooling that orchestrates client onboarding, config compilation, and pipeline execution.
- Mentor the team of data engineers, driving best practices in DataOps, code review, testing, and documentation.
- Proactively review existing processes to identify opportunities to automate manual work, optimise data delivery, and re-design infrastructure for greater scalability.
- Collaborate with analysts, data scientists, and BI teams (PowerBI, Looker Studio, Tableau, etc.) to maximise the value delivered from data models.
- Contribute to CI/CD pipelines (Cloud Build), testing (pytest, dbt tests), and documentation (MkDocs, etc.).
Required
About You
- Strong experience with dbt - macros, Jinja templating, incremental models, seeds, testing, and packages.
- Proficient in Python 3.11+ building CLI tools, data processing, and automation.
- Proficient in SQL, ideally BigQuery dialect.
- Experience with Google Cloud Platform especially BigQuery, Cloud Run, Cloud Functions, Cloud Storage, Pub/Sub, and Cloud Scheduler
- Experience with Infrastructure as Code (Terraform) for provisioning and managing cloud resources.
- Solid understanding of data modelling techniques (star schema, dim/fact architecture, slowly changing dimensions).
- Comfortable with Git (GitHub, branching strategies, pull requests) and CI/CD (Cloud Build or similar).
- Ability to translate business needs into technical specifications.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Highly Desirable
- Experience with Docker and containerised workloads (Cloud Run Jobs).
- Familiarity with CLI frameworks (Click) and config-driven architectures (Pydantic, YAML-based configuration).
- Knowledge of the digital media / paid media industry — we process data from 26+ ad platforms (Google Ads, Meta, DV360, TikTok, etc.).
- Exposure to multi-cloud integrations (Azure Blob, AWS S3, SFTP).
- Mono-repo experience — managing multi-client configurations in a single codebase.
Nice To Have
- Experience with Databricks (and dbt-databricks).
- Familiarity with modern Python dev tooling — Poetry, ruff, mypy, pre-commit.
- Experience with docs-as-code (MkDocs or similar).
Qualities
- Ownership – an ability to manage multiple workstreams across clients with accuracy, and see things through from design to deployment.
- Curiosity – a natural inclination to explore new tools, dig into unfamiliar systems, and understand how things work end-to-end.
- Resourcefulness – an ability to unblock yourself, whether that means reading source code, querying logs, or finding creative workarounds when data or documentation is limited.
- Problem-solving – an ability to think through complex data issues methodically and design clean, maintainable solutions.
- Collaboration – a desire to work openly, share knowledge, and build a team culture where code reviews and pair programming are valued
