Job summary

Afternow is seeking a senior Webflow Systems Lead to own the technical architecture of a multi-site marketing system for a B2B client. You will create a reusable system with a governed component library, relational CMS, and AI agent integration, enabling the client’s marketing team to operate independently.

You’ll collaborate with UI designers, client developers, and another Webflow developer, guiding the team and ensuring performance, accessibility, and security across three sites.

Qualifications

• 5+ years of web development, including 3+ years of professional Webflow work at system level (component libraries, complex CMS)
• Has architected a component-based Webflow system and a relational content model for a large site
• Has handed a system to a non-technical marketing team that now runs it without developers
• Real MCP experience, and has shipped an LLM integration or agent workflow to production, with prompts, instructions and guardrails
• Experience with Algolia or comparable search, ideally multi-index or federated
• Live work we can look under the hood of, including significant custom code, integrations or AI

Responsibilities

• Architect the foundation: components with properties, variants and slots, variables and design tokens, naming, and clear custom-code boundaries across three sites, with performance and accessibility built in
• Work with designers from the start: review Figma components and variables for platform feasibility before they become rebuilds
• Model the CMS: a relational structure connecting products, ecosystems, connectors, use cases, personas and resources, tested across all three sites
• Make the system agent-ready: set up Webflow's MCP server, write agent instructions and reusable skills, and define what agents may and may not change
• Define the connection to the client's products: the client's developers write the integrations; you set the requirements and review the result for performance and security
• Build code components and search: React components for tools such as product finders and assessments, and the cross-site Algolia search layer
• Set up governance and handoff: what marketers and agents can change, how changes are reviewed and published, and documentation so the client's team can run the system
• Guide the team: review other developer's work and keep quality consistent across sites
