Job Description

Job Title: Principal Software Engineer
Location: West Los Angeles, CA
Key Requirements:
  • .NET/C#: Strong, recent hands-on development experience (within the last 12 months). Must still be actively coding.
  • Regulated Industry: Extended tenure in highly regulated environments, preferably financial services, payments, or healthcare.
  • Backend Development: Heavy or exclusive backend experience; not seeking primarily frontend/full-stack developers.
  • High-Volume Systems: Proven experience building scalable, high-throughput transaction processing platforms. Must understand performance optimization and distributed architecture.
  • Azure Cloud: Strong hands-on Azure experience, including AKS, Service Bus, Azure DevOps, and App Services. AWS-only backgrounds are not sufficient.
  • Messaging/Distributed Systems: Kafka, Service Bus, MQ, multithreading, and queuing mechanisms are critical.
  • Test Automation: Experience building automation frameworks and integrating testing into CI/CD pipelines, beyond basic unit testing.
  • Monitoring: Datadog or equivalent observability tools, alerting, troubleshooting, and incident response.
  • AI: Practical experience implementing AI tools or automation within the development lifecycle; must explain what they personally built or automated.
  • Leadership: 8+ years of software engineering experience, including 2+ years in a technical lead capacity. Must demonstrate Principal-level technical depth while remaining hands-on.

Hiring Manager Feedback:
  • Previous candidates have demonstrated general .NET/C# experience but lacked the required transaction throughput, performance engineering, Azure depth, and senior-level architecture expertise.
  • Supplier Focus: Prioritize hands-on Principal-level .NET engineers with long-term regulated-industry experience, high-volume backend architecture, Azure, and distributed systems expertise. Thoroughly validate technical depth and recent coding experience before submitting.
