Software Engineer, Agent

Job Description: RoleOpenArt is hiring a Software Engineer to build the agent layer for their creative products. This is a product-and-systems role focused on extending an agent harness, building MCP servers and CLI tooling, and shipping production frontend experiences that make agent-driven creative workflows feel effortless.

Key Responsibilities: Build and extend the agent harness powering conversational and autonomous creative workflows: tool use, context/memory management, multi-step planning, and sub-agent orchestration. Develop and maintain MCP servers and CLI-based tooling that connect agents to internal services, external model vendors, and creative asset pipelines. Author reusable Agent Skills and structured workflows to handle complex multi-step creative tasks (scene planning, storyboarding, asset generation, revision loops).Contribute to evaluation frameworks and observability to detect regressions and measure agent performance. Ship polished production frontend experiences (React/Next.js) end to end for agent-driven products. Make pragmatic trade-offs between speed, correctness, and scalability and communicate trade-offs clearly. Partner with product, design, and GTM teams to translate user needs into technical solutions.

Requirements: 2+ years of full-stack engineering experience shipping production software. Hands-on experience building LLM-powered agents or agent applications that reached real users (beyond prototypes).Working familiarity with agent harness concepts: tool use, context/memory management, multi-step planning, or sub-agent orchestration. Solid data modeling and schema design skills for real product use cases. Strong AI-assisted coding practice using tools like Claude Code, Codex, or Cursor. Product sense for creating trustworthy and delightful agent experiences. Clear communication skills for explaining agent behavior and technical trade-offs to non-engineers.

Nice to Have: Experience authoring reusable Agent Skills or structured agent workflows. Practical experience building MCP servers or CLI tooling for agents. Exposure to agent orchestration frameworks (Claude Agent SDK, LangGraph) or LLM evaluation/observability tooling. Hands-on experience with image/video generation models. Startup / 0-to-1 product experience. Compensation & Work Setup
