• Integrate third-party APIs and SDKs with authentication, validation, and error handling.
• Develop workflow orchestration, context management, and short- and long-term memory components.
• Implement secure automation with sandboxing, approvals, verification, and rollback.
• Create logs, traces, tests, and evaluation harnesses for reliable production deployment.
• Optimize latency, memory use, model selection, and runtime performance for PC hardware.
• Translate product scenarios into clear technical requirements.

Required Qualifications

• BS/MS in Computer Science, Computer Engineering, or a related field.
• 5+ years of professional software engineering experience.
• Strong C# and .NET development skills.
