🎨 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 - Brand-new function, real mandate — enterprise and team customers are one of our biggest growth levers, and most of the infrastructure behind them hasn't been built yet. You'll be the first engineer on it. - Small team, massive surface area — senior engineers own whole systems, not slices. - Real scale, real stakes — OpenArt serves millions of creators, and enterprise deals will close (or not) on what you ship. - Founder-led engineering culture — both founders are technical and deeply involved in product and architecture. - AI-native product — you'll decide how cutting-edge models get packaged, governed, and sold to teams and enterprises. - High ownership, low process — we value judgment, clarity, and speed over bureaucracy. 🎯 About the Role We're hiring a senior engineer to build the product and infrastructure that lets OpenArt serve teams and enterprises, not just individual creators. That spans the full surface: workspaces and team management, roles and permissions, usage-based billing and procurement-friendly invoicing, audit logs, and the security posture — SSO, data controls, compliance groundwork — that larger customers expect before they'll sign. This is a full-stack role in the enterprise function. You'll move between customer-facing product (admin consoles, billing UI, workspace settings) and the backend and infrastructure underneath it (access control, usage metering, payment integrations, hardening our systems for enterprise-grade reliability and security). You'll work directly with the founders to figure out, in real time, what "enterprise-ready" needs to mean for an AI-native creative platform — and then build it. 🛠 What You'll Do - Design and build core enterprise primitives: organizations/workspaces, roles and permissions (RBAC), SSO/SAML, and audit logging. - Build usage-based billing, invoicing, and payment infrastructure that supports both self-serve and enterprise procurement (e.g. Stripe). - Harden platform security and reliability to the bar enterprise customers expect — access control, data isolation, and groundwork for compliance certifications (e.g. SOC 2). - Design scalable backend architectures and APIs that support multi-tenant, team-based usage patterns. - Build clean, polished frontend experiences (React/Next.js) for admin, billing, and workspace management. - Partner directly with founders, sales, and customers to turn deal-blocking requirements into shipped platform features. - Make pragmatic build-vs-buy calls on infrastructure (billing providers, auth providers, compliance tooling) and clearly communicate the trade-offs. - Define OpenArt's enterprise engineering practices as the function's first hire, and help shape the team that grows around it. ⚙ What We're Looking For Core Requirements - 5+ years of full-stack engineering experience shipping and owning production systems at scale. - Strong system design and data modeling skills — comfortable reasoning about APIs, permission models, multi-tenancy, and data isolation. - Hands-on experience with infrastructure and platform work: cloud architecture, observability, scaling, or reliability engineering. - 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 for B2B — you know what makes an admin console feel trustworthy to an IT buyer and a workspace feel effortless for a team. - Strong communication skills — you can sit in a customer security review or a sales call, then translate what you heard into clear technical trade-offs for non-technical teammates. Nice to Have - Experience with payments or billing systems (e.g. Stripe): subscriptions, usage-based billing, invoicing, disputes. - Experience with security or compliance work: SSO/SAML, RBAC, audit logging, SOC 2 / GDPR groundwork. - Experience selling to or building for enterprise customers, including procurement and security-review cycles. - Startup experience, or ownership of a large product surface from 0 to 1. 💰 Compensation - $500k+ total compensation including base salary, bonus, equity. - Equity — meaningful ownership in what you build. - High autonomy, high growth environment. 🌍 Work Setup - Bay Area preferred (hybrid available). - Visa sponsorship available. 🎯 What Success Looks Like in 3–6 Months - Workspaces, roles, and permissions are live in production and used by paying teams. - Enterprise billing — usage metering, invoicing, procurement-friendly payments — is shipped and stable. - At least one enterprise deal has closed on the strength of features you built (e.g. SSO, audit logs). - SOC 2 groundwork is underway, and you can walk a customer's security team through our posture with confidence. - You're setting the direction for enterprise engineering — pushing ideas, not waiting for specs. If you want to build the platform that turns a consumer AI product into an enterprise business — and own it from day one — we'd love to talk.
