  • Collaborate with engineers, data scientists, and product managers to deliver new features and ML-driven experiences
  • Improve performance, reliability, observability, and cost-efficiency of backend systems
  • Contribute to architectural decisions and technical direction of AI and backend platforms

What we're looking for

  • Proven experience building backend services at scale
  • Proficiency in C# / .NET
  • Familiarity with cloud infrastructure and observability tools (e.g. Kubernetes, Grafana, etc.)
  • Understanding of API design, distributed systems, and system reliability
  • Strong understanding of software development best practices, a quality-first mentality and approach
  • You might also have

  • Experience in ad tech, programmatic advertising, or real-time bidding systems
  • Background with infrastructure-as-code (e.g., Terraform)
  • Familiarity with networking, caching, or real-time data pipelines
  • Exposure to ML infrastructure or LLM inference deployment
  • Familiarity with Unity or similar 3D engines
  • Familiarity with languages like Python, Golang
