Senior/Staff Software Engineer, Agent
AI summary of the role
Senior/Staff engineer to lead agentic architecture for OpenArt's AI creative platform, owning the agent harness (tool use, memory, orchestration, evals) behind products like Director.
What you’ll do
- Own end-to-end architecture of the agent harness for conversational and autonomous creative workflows
- Design multi-step planning, tool use, and sub-agent orchestration across model vendors with clear failure modes
- Build MCP servers, CLI tooling, and reusable Agent Skills
- Create evaluation and observability stack (evals, tracing, quality gates)
What you’ll bring
- 7+ years full-stack engineering with production systems at scale
- 2+ years building LLM-powered agents in production
- Deep hands-on agent architecture: tool use, context/memory, multi-step planning, orchestration
- Experience designing evaluation frameworks and observability for agentic systems

🎨 About OpenArt OpenArt is an AI storytelling and visual creation platform used by millions of creators worldwide. We're building the next generation of creative tools powered by cutting-edge AI — enabling anyone to create videos, visuals, characters, and stories with unprecedented speed and imagination. We believe the future of creativity is AI-native, and we're shaping that future. 🚀 Why Join OpenArt - Ground floor of a new category — help define what "agent" means for creative work, the way Director redefined what "directing" means for video. You'll set the architecture everything else is built on. - Own the whole agent layer — not a service, not a slice. Harness, orchestration, memory, evals, tooling: the entire system is yours to design and lead. - Real scale, real stakes — your agents run for millions of creators, and every improvement in reliability, latency, or quality shows up in the product within days. - Founder-led engineering culture — both founders are technical and deeply involved in product and architecture. - AI-native product — you'll decide how frontier models get orchestrated, constrained, and exposed as experiences that feel effortless rather than technical. - High ownership, low process — we value judgment, clarity, and speed over bureaucracy. 🎯 About the Role We're hiring a senior or staff engineer to lead the agentic architecture behind OpenAr [... source excerpt omitted ...] ke this further: longer-horizon planning, tool use across multiple model vendors, memory across sessions, sub-agent orchestration, and the harness that keeps all of it reliable in production. This isn't a research role — it's a product-and-systems leadership role. You'll define the architecture of the agent harness (tool use, context engineering, multi-step planning, orchestration, evaluation), set the engineering standards the team builds against, and stay hands-on: building the MCP servers and CLI tooling around it, and shipping the frontend experiences on top of it.
