We are seeking an experienced Agent Engineer to build and scale the agent and workflow layer behind a cloud-based creative platform. The ideal candidate has experience shipping production AI or backend systems, understands agent runtime behavior, and can design reliable model orchestration beyond basic prompt-based applications.

This role focuses on developing intelligent workflow systems that integrate multiple AI models, tools, and services across image, video, audio, text, and other creative workflows.

Key Responsibilities

• Build and maintain agent runtimes supporting planning, tool usage, memory, retrieval, context management, and workflow execution.
• Orchestrate multiple AI models and providers across various generation workflows.
• Design routing, retry mechanisms, fallbacks, latency optimization, cost controls, and failure recovery systems.
• Develop workflow memory systems that preserve project context, assets, templates, style preferences, and previous outputs.
• Implement evaluation frameworks, regression testing, benchmarking, human review workflows, and quality metrics.
• Improve production reliability through queue management, monitoring, cancellation handling, progress tracking, and graceful recovery mechanisms.
• Collaborate with cross-functional teams to deliver scalable and user-friendly AI workflow solutions.

Required Qualifications

• 3+ years of experience building and shipping AI, agent-based, backend, infrastructure, or production software systems.
• Strong proficiency in Python and/or TypeScript.
