About the job

Requirements
  • At least 4 years of experience scaling distributed microservices and backend systems in production cloud environments.
  • Strong expertise in C# and .NET for high-throughput, low-latency application development.
  • Production experience with Kubernetes, relational schema design, SQL query performance tuning, and messaging infrastructure including Kafka and Azure Service Bus.
  • Hands-on integration of AI-assisted engineering tools, including Cursor, Claude Code, and sub-agents, into daily workflows.
Responsibilities
  • Architect and operate low-latency, event-driven microservices that handle live-event traffic bursts without downtime.
  • Bridge machine-learning models into production by building resilient deployment pipelines that handle model drift, context limits, and non-deterministic outputs.
  • Own end-to-end service delivery from initial RFC design through zero-downtime deployment and post-launch telemetry.
  • Optimize pub/sub event pipelines across Kafka and Azure Service Bus to decrease processing latency and increase data throughput.
  • Debug distributed performance bottlenecks and scale Kubernetes compute clusters handling concurrent, continuous media processing.
  • Collaborate with machine-learning engineers and data scientists to design systems that degrade gracefully during inference failures.
Desired Qualifications
  • Operational knowledge of production machine-learning and AI behavior, including inference performance, context limits, and non-determinism.
  • Azure cloud infrastructure experience, including networking, IAM, and cost/performance optimizations, or exposure to video/media processing pipelines.
