Senior Data Engineer (3 Month Contract)

Trailmix Games
London
GBP 50,000 - 75,000
Job description

Senior Data Engineer (3-Month Contract)

Trailmix is an award-winning studio based in the heart of London, backed by mobile giants Supercell. We are actively growing the talented team behind our hit game Love & Pies, and setting up new titles with equally high ambition. If you want to shape the foundation of data in our games — both live and in development — this could be the perfect role for you.

About the role:

This is a 3-month contract position reporting to the Engineering Lead. You will work alongside one other Data Engineer and collaborate closely with our Data Analytics, Product, Marketing, and Game teams.

This role spans both live game support and the setup of data infrastructure for new games. You'll ensure we have robust pipelines and quality data for decision-making, and help scale systems to support complex event economies, growth loops, and game telemetry.

We’re looking for someone who can quickly contribute value by bringing practical solutions and modern best practices in data engineering — ideally with experience in gaming or similarly high-volume consumer applications.

Responsibilities:
  • Design, develop, and maintain scalable, low-latency data pipelines to support gameplay, monetization, UA, and LiveOps.
  • Work across both new and live games to ensure reliable ingestion and transformation of game telemetry, event data, and third-party signals (e.g., marketing APIs).
  • Ensure data integrity, completeness, and consistency via automated monitoring and validation tooling.
  • Optimize and extend our cloud data warehouse (Google BigQuery) for performance and cost.
  • Develop ETL/ELT jobs and data models to enable fast analytics and experimentation.
  • Partner with analysts and product managers to define data tracking specifications and ensure implementation alignment.
  • Contribute to infrastructure automation, CI/CD pipelines, and observability for data systems.
  • Stay up to date on industry best practices for scalable and secure data systems in mobile gaming.

Requirements:
  • Strong experience with Python and SQL for data engineering and transformation.
  • Deep understanding of cloud-based data architecture, particularly with GCP (BigQuery, Cloud Functions, Pub/Sub, etc.) or AWS equivalents.
  • Hands-on experience with orchestration tools such as Airflow or DBT.
  • 3+ years in data engineering, preferably including at least one role supporting a live or F2P game.
  • Experience with analytics and marketing APIs (e.g. Appsflyer, Applovin, IronSource).
  • Familiarity with event-based systems and near real-time data streaming a plus.
  • Strong communication skills — able to explain technical decisions to non-technical stakeholders.

Bonus:
  • Exposure to modern analytics tools (Looker, Metabase, Mode, Tableau) and event tracking standards (Snowplow, Segment).
  • Experience supporting game economy telemetry, player segmentation, and A/B testing.
  • Interest in game development and/or mobile gaming industry trends.

Why Trailmix?

As a member of our team, you’ll work in an environment where collaboration and creative energy drive everything we do. We believe that working closely with colleagues from across departments is essential to crafting the best experiences for our players. Our office is a place where ideas come together, and we work side by side to turn them into reality.

Our London Studio Location

Our hybrid work model combines the flexibility of remote work with the creative energy of being together in person.

We work from our Kings Cross studio together three days a week — Monday, Thursday, and Friday, because we believe great games (and great teams) are built through genuine collaboration.

These days are focused, energised, and designed for impact:

  • We solve problems faster
  • We share ideas in the moment
  • We drive decisions that move us forward

This rhythm helps us deliver our best work not just for each other, but for our players. It’s how we build momentum, grow together, and stay ahead in a fast-moving industry.

Our Inclusive Culture

Trailmix was founded to make a positive impact on our players, our community, and our colleagues. We are committed to creating an inclusive culture, and our priority is fostering an environment where people can flourish. We think it’s vital that players see themselves represented in games, and Love & Pies, we showcase the beautiful diversity of life. Love & Pies represents the people we are and the people we love, and we’re always looking to add more people who want to design games for everyone.
