🎯 What you’ll own & the role:

Senior Software Engineer on the C&E team.

The C&E team 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 you’ll take technical ownership of backend systems that power our C&E initiatives, including:

• 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.

• Collaborate closely with Product, Data, and other Engineering teams to turn customer insight into reliable platform capabilities.

Problems you'll help solve:

• How do we scale customer data processing as usage grows across regions and products?

• How do we ensure personalization logic stays flexible without becoming brittle?

• How do we reduce bugs and operational noise while increasing delivery speed?

• How do we enable other teams to build on top of the CDP without tight coupling?
  

🧰Stack:

• AWS

• Infrastructure as Code: Terraform, Helm

• Container orchestration: Kubernetes, Docker

• Monitoring: Grafana, ELK stack

• Backend: Python Django, FastAPI, Celery

• Frontend: React, TypeScript (mono-repos, module federation)

• Databases: PostgreSQL, Redis, RabbitMQ, Kafka

• CI/CD: GitLab CI, ArgoCD.

🦄 You might be a great fit if:

• You’ve designed and owned backend systems used by multiple teams or products.

• You’ve worked in a SaaS or product-led environment at meaningful scale.

• You’re comfortable making architectural decisions and explaining trade-offs.

• You enjoy improving existing systems as much as building new ones.

• You communicate clearly in English and collaborate well across disciplines.
