Data Engineer
Build the data infrastructure that keeps an AI-driven marketing platform running at scale.
You are a data engineer who finds satisfaction in building things that work reliably at scale. You care about clean pipelines, solid data quality and infrastructure that performs when it matters. At Billy Grace, you will join a focused tech team building the data foundation of an AI-driven marketing platform. We already process over 10 million sessions a day and we are growing fast.
Your Impact
As a Data Engineer at Billy Grace, you keep the data flowing cleanly and reliably. You design and maintain the infrastructure that makes our AI product possible, and your work directly shapes the quality of the decisions our platform helps marketers make. In a small, close-knit tech team, your contributions are visible from day one.
What You'll Do
You will take ownership of the data pipelines at the heart of our platform. That means designing, improving and scaling them as the business grows, working hands-on with PySpark to strengthen and extend our codebase, and improving our distributed cluster setup inside Databricks so everything runs faster and more reliably.
You will build frameworks for data validation and quality checks, write unit tests for pipelines and work through a backlog of improvements and new pipeline additions. You will also contribute to the design and scaling of a database that is central to our core application, making sure it holds up as usage grows.
You will collaborate closely with data scientists and full-stack developers, pick up bugs and solve real problems. This is not a ticket-only function. You will have a genuine seat at the table when architectural decisions are made.
What We Offer
You’ll join a team that builds together, learns together and makes each other better. We’re working on something big with energy, curiosity and plenty of room for your ideas. Here’s what you can expect:
A salary based on your background and experience
A MacBook and a workspace in the heart of Amsterdam (hybrid).
25 vacation days + your birthday off.
Lots of trust, freedom and space for your ideas.
Access to OpenUp for mental health and wellbeing.

Daily lunch, great coffee and an open, warm culture.
Opportunities to learn, experiment and grow.

Why Billy Grace
Billy Grace is the first fully operational AI Digital Marketing Partner. Marketing has shifted from creative to data-driven over the past two decades, and our mission is to free marketers from the never-ending cycle of data management and repetitive tasks so they can focus on what actually matters: creativity, strategy and sustainable growth.
In practice, that means:
Meetings only when they move the work forward, most days are for building, not talking
No corporate theatre no vague roadmaps, buzzwords or politics
Lightweight process we skip heavy Scrum rituals in favour of direct collaboration
Fast decisions, real ownership if you own a feature, you ship it
If you’re done with planning poker, endless standups and process for process’ sake, you’ll feel at home here. Together, we build technology used daily by brands and agencies that want to move fast from Patagonia to XXL Nutrition, and from Draft Digital to Happy Horizon.
Do you yourself in this? We would love to hear from you.
For this role, we are currently not collaborating with external agencies.
