Job summary

OpenArt AI in the Bay Area is seeking a Senior Software Engineer to build the enterprise platform for teams and customers. You will own admin consoles and the backend—from RBAC and SSO to usage metering and procurement-friendly payments.

Collaborate with the founders to define enterprise-ready capabilities, implement multi-tenant architectures, and push features that advance security, SOC 2 readiness, and scalable collaboration for enterprise clients.

Qualifications

• 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

Responsibilities

• 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
