Job Description:

Our Customer Data Platform (CDP) sits at the core of how studios understand and connect with their customers. It ingests, processes, and activates large volumes of customer events across B2B and B2C products — powering personalization, segmentation, lifecycle messaging, and community-driven growth. As a Senior Backend Engineer on the CDP team, you’ll work on systems that directly shape how millions of end users experience our platform — not by adding surface-level features, but by improving the foundations that make personalization, scale, and reliability possible. This is a role for someone who enjoys ownership, technical depth, and long-term thinking.

Job Responsibility:

  • Take technical ownership of backend systems that power our CDP initiatives
  • Designing and evolving customer data pipelines that ingest events at scale and make them available in near real time
  • Building and maintaining robust data models and APIs that enable segmentation, targeting, and personalized experiences
  • Improving stability, scalability, and observability of high-throughput systems used across multiple product verticals
  • Refactoring and extending parts of our modular monolith, enabling teams to move faster without sacrificing clarity or ownership
  • Collaborating closely with Product, Data, and other Engineering teams to turn customer insight into reliable platform capabilities

Requirements:

  • Designed and owned backend systems used by multiple teams or products
  • Worked in a SaaS or product-led environment at meaningful scale
  • Comfortable making architectural decisions and explaining trade-offs
  • Enjoy improving existing systems as much as building new ones
  • Communicate clearly in English and collaborate well across disciplines
What we offer:
  • Hybrid work setup + work-from-anywhere weeks
  • Full health insurance with Alan
  • Fitness perks (DiR Gym, Yoga One)
  • Relocation support for Barcelona
  • Equity that actually matters as we scale
