Senior Platform Data Engineer - Cardiff
Senior Data Platform Engineer – Hybrid (Cardiff)
At Terminal Velocity, part of the Rocket Science Group, every game is an ecosystem of interconnected systems beyond pure gameplay. Our platform and server teams design, build, and improve the back-end and publishing infrastructure necessary for global game distribution.
In search of a Senior Data Platform Engineer to collaborate on designing, building, and enhancing reliable data systems for both our partners and internal teams.
About the Role
As a Senior Data Platform Engineer, you will:
- Develop scalable, robust data solutions for games and related platforms, including:
- Telemetry pipelines
- Analytics platforms
- Data warehouse/lakehouse architectures
- Reporting foundations
- Backend integrations
- Contribute to every stage of the data engineering lifecycle, from schema design to observability and validation.
- Act as a technical bridge between stakeholders and customers, clarifying ambiguous requirements, breaking down complex projects, estimating timelines, and making pragmatic trade-offs.
- Apply expertise in data modelling, quality assurance, and observability to ensure trustworthy data for both technical and non-technical teams.
While games industry experience is useful, it’s not mandatory. Instead, we prioritise:
- Strong data engineering fundamentals
- Subject-matter expertise in areas like pipelines, modelling, and observability
- Expertise in decision-making under ambiguity
- Willingness to collaborate across disciplines, from backend to tooling
Here, data engineering is the core focus, but we value adaptability—ensuring that accepts (and thrives) in adjacent fields like backend services, SDK development, or new technologies as needed.
Key Responsibilities
- Design data pipelines that ingest, process, and retain game data efficiently.
- Build resilient data models that support monetisation, analytics, and operations.
- Align with stakeholders to translate business needs into scalable, maintainable data systems.
- Ensure data accuracy, consistency, and usability through testing, validation, and observability.
- Champion cost-effective infrastructure for cloud and hybrid environments.
- Diversify skills across technical areas (infrastructure, backend, tooling) when business needs dictate.
