Product Designer

About the Role OpenRouter is the largest marketplace of LLMs, providing a unified API to access and orchestrate models across providers. As the platform grows, so does the complexity of how developers discover, evaluate, and integrate models into real applications. We're hiring a Product Designer to help shape both the product and how it's presented. This role spans core product surfaces (user dashboards, documentation, model pages, rankings, policy & guardrails, chatroom) and external-facing surfaces (landing pages, email templates, and other marketing touchpoints). You'll help define how OpenRouter works and how it communicates. This is a hands-on role for someone who ships. You'll operate in an AI-first workflow, using modern tools to move quickly from idea prototype production-quality output. You should be comfortable working in the space between design and development-building, iterating, and refining in close collaboration with engineers. What You'll Work On • Core product surfaces (dashboards, model pages, usage + analytics) • Model discovery, comparison, and evaluation experiences • Developer workflows (API onboarding, docs, playgrounds, integrations) • Marketing and brand surfaces (landing pages, email templates, growth experiments) • New product directions (tooling, marketplaces) • Rapid prototypes to explore and validate ideas Key Responsibilities Product & UX • Design clear, intuitive interfaces for complex systems (LLMs, APIs, routing, pricing, latency) • Turn ambiguous ideas into concrete product direction and shipped experiences • Own work end-to-end: concept prototype production Marketing & Brand • Design and build high-quality landing pages and growth surfaces • Create scalable templates (email, content, campaigns) • Help evolve OpenRouter's visual identity as the product expands AI-First Execution • Use AI tools to accelerate design, prototyping, and iteration • Move fluidly between design tools, code-adjacent environments, and production surfaces • Prototype ideas quickly and validate through real usage Systems & Consistency • Contribute to and evolve the design system • Create reusable patterns for technical and data-heavy interfaces • Maintain consistency across product and marketing surfaces Collaboration • Work closely with engineers in a fast, low-process environment • Review and understand PRs, frontend changes, and implementation details as needed • Contribute to product and growth strategy, not just execution • Communicate through prototypes and shipped work rather than long specs What We're Looking For Core Requirements • 3-8+ years of product design experience • Strong portfolio of shipped work • Experience with complex or technical products (developer tools, SaaS, data-heavy apps) Design Engineering Fluency • Comfortable reading and understanding frontend code, PRs, and engineering workflows • Able to collaborate directly with engineers on implementation details • Able to use code-based or AI-assisted tools to prototype and iterate • Ability to write code is a plus, but not required AI-Forward Builder • Comfortable using AI tools as a core part of your workflow • Able to move quickly from idea to implementation using modern tooling • Interested in how AI changes how products are designed and built Product Thinking • Strong ability to simplify complex systems • Good judgment on scope, prioritization, and tradeoffs • Comfortable working with ambiguity Craft & Execution • High bar for visual design, interaction design, and clarity • Ability to produce production-ready work with minimal iteration • Attention to detail across both product and marketing surfaces Nice to Have • Experience with AI/ML products or developer platforms • Experience designing data visualization or analytics interfaces • Experience designing high-performing marketing sites or growth surfaces • Ability to write or meaningfully modify frontend code (e.g. React, HTML/CSS) Please mention the word **FLEXIBILITY** and tag RMTY3Ljk5LjIwNy4yMjM= when applying to show you read the job post completely (#RMTY3Ljk5LjIwNy4yMjM=).
