Software Engineer, Agent
About The Position
OpenArt is seeking engineers to build the agent layer for its next-generation creative products, starting with Director, a tool that allows users to create cinematic videos by chatting with AI. The role involves building agent infrastructure for features like longer-horizon planning, multi-vendor tool use, cross-session memory, and ensuring production reliability. This is a product-and-systems role focused on building and extending the agent harness (tool use, context management, multi-step planning, evaluation), developing MCP servers and CLI tooling, and shipping frontend experiences that are user-friendly. The engineer will collaborate closely with founders, the agent team, and design to translate user needs into a scalable and reliable system.
Requirements
- 2+ years of full-stack engineering experience shipping production software.
- Hands-on experience building LLM-powered agents or applications that have reached real users — not just prototypes or demos.
- 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.
- A strong AI-assisted coding practice — you use tools like Claude Code, Codex, or Cursor as a core part of how you build, and have real opinions about what makes them work well.
- Product sense — you think about what makes an agent experience feel trustworthy and delightful, not just functional.
- Clear communication — you can explain agent behavior and technical trade-offs to teammates who aren't engineers.
Nice To Haves
- 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 similar) or LLM evaluation / observability tooling.
- Hands-on experience with image / video generation models.
- Startup experience, or having built something 0 to 1 (side projects count).
Responsibilities
- Build and extend the agent harness that powers 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 — scene planning, storyboarding, asset generation, revision loops.
- 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.
Benefits
- $300k+ total compensation including base salary, bonus, equity.
- Equity — meaningful ownership in what you build.
- High autonomy, high growth environment.
- Visa sponsorship available.
