Job Summary

This is a remote position.

If you care about solving tough distributed systems problems making a visible impact on global tech products and working on bleeding-edge sync and streaming infrastructureit doesnt get much cooler than our client. Were seeking a pragmatic performance-driven Distributed Systems Engineer to architect and scale the backbone of our next-generation data infrastructure. This is a critical technical leadership role for high-impact engineers who have mastered building optimizing and operating large-scale multi-cloud backend platforms. You will join a peer group of world-class engineers who have redefined reliability and throughput at transformative Canadian tech companies.

What Youll Do
  • Design and implement robust data-sync pipelines real-time streaming layers and high-throughput backend services for modern infrastructure at petabyte scale.
  • Lead architecture of multi-region and multi-cloud sync caching and event collection systems pushing platform boundaries for performance resiliency and compliance.
  • Drive adoption of cloud-agnostic architectures (AWS GCP Azure) to power global products with strict data residency and disaster recovery requirements.
  • Optimize low-latency APIs and backend services for observability scalability security and cost-efficiency.
  • Spearhead migration of monolithic systems to distributed microservices-based deployments (Kubernetes Docker).
  • Partner with product compliance and data teams to deliver highly available infrastructure supporting hundreds of millions of daily transactions.
  • Influence the technical roadmap for cutting-edge data streaming CDC and caching solutions (Kafka Flink Debezium Redis DynamoDB)
  • Champion infrastructure-as-code advanced monitoring and automation using modern tools (Terraform Grafana Prometheus Datadog Jaeger).
  • Lead incident response postmortem analysis and end-to-end reliability engineering.
