AI Agent Engineer — Creative Tools Platform

OpenArt; San Carlos (CA); Hybrid; USD 300,000 - 450,000; Full time

Job summary

OpenArt, an AI storytelling and visual creation platform, seeks engineers to build the agent layer behind its next generation of creative products, starting with Director — enabling longer-horizon planning and cross-model tool use at scale.

This product-and-systems role is hands-on, not pure research. You’ll work with founders, the agent team, and design to turn ambitious agent capabilities into reliable experiences that millions of creators can use daily.

Qualifications

• 2+ years of full-stack engineering experience shipping production software.
• Hands-on experience building LLM-powered agents with real users.
• Familiar with agent harness concepts: tool use, memory management, multi-step planning, or sub-agent orchestration.
• Solid data modeling and schema design skills for real product use cases.
• A strong AI-assisted coding practice — you use tools like Claude Code, Codex, or Cursor as a core part of how you build.
• Product sense — you think about what makes an agent experience trustworthy and delightful.
• Clear communication — you can explain agent behavior and trade-offs to non-engineers.

Responsibilities

• Build and extend the agent harness powering OpenArt's conversational and autonomous creative workflows: tool use, context/memory management, multi-step planning, and sub-agent orchestration.
• Build and maintain MCP servers and CLI‑based agent tooling that connect our agents to internal services, external model vendors, and creative asset pipelines.
• Author reusable Agent Skills and structured workflows that let agents reliably handle complex, multi-step creative tasks.
• Contribute to evaluation frameworks and observability so the team knows when an agent is working well, and can catch regressions before users do.
• Ship polished, production frontend experiences (React/Next.js) for agent‑driven products, end to end.
• Make pragmatic trade‑offs between speed, correctness, and scalability — and communicate them clearly.
• Partner closely with product, design, and GTM to translate user needs into technical solutions.
• Track the fast‑moving agent ecosystem (MCP, Agent Skills, orchestration frameworks) and bring the best of it into OpenArt's stack.
