Senior Data Engineer

About the role
Senior Data Engineer | GCP, BigQuery & Data PlatformI’m recruiting for a growing AdTech company looking for a Senior Data Engineer to take real ownership of its analytical data platform. This is not a role where you inherit a perfectly organized warehouse and spend your time maintaining pipelines. You’ll help define the architecture across the entire data lifecycle — from source ingestion and durable storage through BigQuery, data marts and business intelligence — while acting as the senior technical authority for how the platform evolves.
What you’ll be doing:
- Own and evolve a production GCP / BigQuery data platform
- Design scalable data models, warehouses and governed data marts
- Build production pipelines using Python, Apache Beam, Dataflow, Airflow and Cloud Composer
- Solve hard data problems around retries, idempotency, schema evolution, backfills and late or duplicate events
- Define trusted metrics used across product, finance and leadership
- Improve reliability, governance, security and cost efficiency across the data platform
- Turn ambiguous business needs into a practical technical roadmap
- Help shape the architecture for the company’s future data organization
- What they’re looking for:
- Deep production experience with BigQuery and GCPStrong hands-on Python and advanced SQLProduction experience with Apache Beam / Dataflow
- Strong Airflow / Cloud Composer experience
- Experience designing or materially rearchitecting cloud data warehouses and data lakes
- Strong understanding of data modeling, reliability and governance
- A track record of independently owning complex data-platform initiatives
- Ability to work across technical and non-technical teams and drive decisions without needing a large platform organization around you
Experience in AdTech, programmatic advertising or retail media is highly valuable, but it is not a hard requirement. Strong engineers from other high-volume event environments will also be considered.
Experience with Superset, dbt/Dataform, Terraform, CI/CD and data governance is also a plus.
This is a great fit for someone who wants to be the person designing the data platform rather than simply consuming it — with real influence over architecture, standards and the roadmap.

Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
