• Collaborate directly with founders, engineering leads, product managers, and marketing to drive design strategy and execution from 0-to-1.

• Leverage modern AI tools for rapid concept exploration and production-ready asset creation, embodying an AI-native operating style.

📝 Enhancement Note: This role is positioned as a "Founding Product Designer," indicating a significant opportunity to shape the design direction and brand identity of a nascent company and its core open-source project (vLLM). The emphasis on "0-to-1" and "full-stack design" suggests a broad scope of responsibility beyond typical product design, encompassing brand, marketing collateral, and internal tooling. The target audience for this role is someone who can operate with a high degree of autonomy and has a strong technical curiosity, particularly within the AI and developer tool space.

📈 Primary Responsibilities

• Design and ship high-impact visual assets for model launches, technical content, and ecosystem announcements within the first 30 days.

• Develop initial UI/UX designs for Inferact's production tooling and developer dashboards, expanding the design footprint across the core website and interactive developer pages within 60 days.

• Lead the core design efforts for Inferact's enterprise product, refining UI/UX for developer tools, optimizing developer workflows, and establishing a unified design system from brand assets to product components within 90 days.

• Define and evolve the visual language and brand identity for both the Inferact company and the vLLM open-source project.

• Create compelling visual narratives for technical blog posts, partner announcements, and community engagement initiatives.

• Design and iterate on user interfaces for developer tools, dashboards, and internal platforms, ensuring ease of use and efficiency.

• Collaborate with engineering teams to ensure design feasibility and successful implementation of design systems and product interfaces.

• Conduct user research and usability testing to inform design decisions and validate product experiences.

• Maintain a high bar for aesthetic quality, typography, layout, and overall visual systems across all touchpoints.

📝 Enhancement Note: The 30-60-90 day milestones clearly outline an aggressive onboarding and impact expectation for this founding role. The responsibilities span from immediate marketing and content design to long-term product interface and design system ownership, requiring a versatile designer capable of strategic vision and tactical execution.
