  • Practical knowledge of observability tooling (CloudWatch, Grafana, Prometheus)
  • Comfortable writing SQL for analytical workloads (e.g., Athena)
  • Experience with ElasticSearch/OpenSearch (nice to have)
  • Familiarity with GitHub Actions (nice to have)
  • Interest in and active use of AI-based tooling to support efficient engineering practices
  • A technically strong, product-focused mindset that balances engineering quality with product priorities

Some of our exciting technical challenges:

  • Scaling infrastructure globally to provide a low-latency experience to our users
  • Enabling real-time design collaboration between our users
  • Developing social-graphs to help users enrich their stories

  • Core Platform: Cloud-hosted infrastructure running 30+ micro-services on AWS using Kubernetes (EKS) and gRPC for interservice communication
  • Serverless stack with over 250 Lambda functions for event processing
  • Terraform-managed infrastructure
  • DynamoDB application database
