Summary

Our client is a Southern California product engineering company building streaming software for media organizations. Its platform supports live and on-demand content across web, mobile, and connected TV. They are seeking a Senior / Principal .NET Backend Software Engineer to build and improve the services behind their streaming products.

This is a hands-on role focused on C#/.NET, distributed systems, and AWS. You will develop APIs, event-driven services, and content ingestion workflows while improving the reliability and performance of a large backend platform. Principal-level candidates should also have experience leading the architecture of a substantial backend domain.
Responsibilities
  • Design and build C#/.NET REST APIs, background workers, asynchronous workflows, and service-to-service integrations.
  • Improve microservice architecture, including service boundaries, messaging, retries, circuit breakers, and idempotency.
  • Build and operate services on AWS, selecting containers, serverless, or other compute options based on workload requirements.
  • Support content ingestion, processing, packaging, and delivery workflows for live and on-demand media.
  • Improve observability through metrics, logs, distributed tracing, alerting, and service level objectives.
  • Build security into services using authentication, role-based access, secrets management, and secure communication.
  • Guide technical decisions and help resolve complex production issues across services.
Required Experience
  • Advanced, hands-on C#/.NET experience building and operating production backend platforms, including APIs, background processing, and asynchronous workflows.
  • Experience with microservices at meaningful scale, including independently deployed services, event-driven design, queues, failure handling, and production observability.
  • Strong AWS experience building and operating production systems using services such as ECS/Fargate, EKS, Lambda, API Gateway, SQS, SNS, EventBridge, RDS/Aurora, DynamoDB, S3, CloudFront, IAM, or CloudWatch.
  • Sound judgment about serverless and container-based architecture, including performance, concurrency, runtime limits, operational needs, and cost.
  • Experience with a relational database such as SQL Server or PostgreSQL, a NoSQL database, and a cache such as Redis.
  • Hands-on experience with OAuth 2.0 or OIDC, JWT, role-based access control, secrets management, Docker, and CI/CD.
  • Experience managing AWS infrastructure through Terraform, CloudFormation, or similar tools.
Strongly Preferred
  • Production experience with Kafka or a comparable event streaming platform.
  • Kubernetes experience in addition to strong AWS platform experience.
  • Experience with high-throughput systems, media workflows, job orchestration, or multi-tenant SaaS.
  • A record of improving the cost, reliability, or performance of an existing AWS platform.
  • For Principal-level candidates, experience setting architecture for a substantial backend domain.
Nice to Have
  • Snowflake or analytics pipeline experience.
  • Familiarity with streaming, transcoding, or CDN technology.
  • Go experience.

The Offer:
  • $140,000-$160,000 base salary
  • Bonus incentives based on individual and company performance
  • Full benefits
  • Stock options
  • 401(k) match
