Parallel
About us Parallel is a web infrastructure company. Our products are used by leading businesses in sales, marketing, insurance, and coding to build best-in-class AI agents with flexible and powerful programmatic access to the web. We've raised $230 million from Kleiner Perkins, Sequoia, Index Ventures, Spark Capital, Khosla Ventures, First Round, and Terrain to build the web for AIs. We're currently valued at $2 billion and we're forming a world-class team of engineers, designers, marketers, sellers, researchers, and operational experts to achieve our mission. About you You're an expert at modern front-end frameworks, maintainable UI architecture, and building UIs that feel intuitive, fast, and beautiful. You have strong production experience with TypeScript, modern CSS, Vercel, and Sanity (or similar headless CMS platforms). You understand responsive design, web performance, and accessibility. You can read API documentation, work effectively with backend teams, and have good instincts for what makes a developer tool feel intuitive versus frustrating. Experience with data visualization or technical documentation sites is a plus. The role Parallel is growing rapidly and in need of an experienced front end development lead—someone to take our web properties from their early iterations to a higher bar of excellence as we expand to serve more customers. You'll design, build, and refine the web experiences that showcase what our powerful APIs are capable of. You'll focus on three key properties: Parallel.ai — our marketing website Platform.parallel.ai — our developer playground and dashboard Docs.parallel.ai — our technical documentation Responsibilities Lead web deployment and hosting operations across our web properties Work with product and marketing teams to develop compelling web experiences that showcase Parallel's core messaging and product features Collaborate with dev rel and forward-deployed engineers on demos and cookbooks that help developers understand technical concepts like structured web search, confidence scoring, and multi-hop agentic research Own the technical foundation and architecture decisions for our web presence as we scale Life at Parallel Our team works fully in-person , between our Palo Alto HQ and San Francisco office. We’re a flat, talent-dense organization dedicated to solving technical and creative problems. We seek like-minded individuals who share our passion for applying science, creativity, and consistency to big and complex problems with equally big outcomes. These are our values: Own customer impact: It’s on us to ensure real-world outcomes for our customers. Obsess over craft: Perfect every detail because quality compounds. Accelerate change : Ship fast, adapt faster, and move frontier ideas into production. Create win-wins : Creatively turn trade-offs into upside. Make high-conviction bets : Try and fail. But succeed an unfair amount.
