This flexible approach gives team members the best of both worlds: plenty of focus time along with in-person collaboration that helps foster trust, innovation, and a strong team culture.\nAbout Superhuman\nSuperhuman is the AI productivity platform on a mission to unlock the superhuman potential in everyone. The Superhuman suite of apps and agents brings AI wherever people work, integrating with over 1 million applications and websites. The company’s products include Grammarly’s writing assistance, Superhuman Docs’s collaborative workspaces, Mail’s inbox management, and Go, the proactive AI assistant that understands context and delivers help automatically. Founded in 2009, Superhuman empowers over 40 million people, 50,000 organizations, and 3,000 educational institutions worldwide to eliminate busywork and focus on what matters. Learn more at superhuman.com and about our values here.\nThe Opportunity\nSuperhuman is building the AI productivity platform that works everywhere people do - and the front end is where it all comes together. Our Front-End engineers own the interfaces that put AI capabilities directly into users' hands: the Chrome extension and desktop app for Go (our proactive AI assistant), the editor and collaboration surfaces in Superhuman Docs, the inbox experience in Superhuman Mail, and the admin controls that let enterprises deploy it all at scale.\nThis isn't typical front-end work. You'll build interfaces that stream and render AI-generated content in real time, design interaction patterns for inline agent suggestions that appear while users are writing, and create the tools that let anyone build and customize their own AI agents - no code required. The craft challenges are deep: orchestrating state across browser extensions, native desktop apps, and web surfaces; making agentic workflows feel instant and fluid; and shipping a consistent experience across a product suite that reaches millions of users.\nSuperhuman's engineers have the freedom to innovate and uncover breakthroughs - and, in turn, influence our product roadmap. The complexity of our technical challenges is growing rapidly as we scale AI-powered features across every surface. You can hear more from our team on our technical blog.\nAs a Front-End Software Engineer, you will:\nBuild the interfaces for AI-powered products used by millions - including real-time chat experiences, inline agent suggestions, document editors, and agent builder tools.\n\nDesign and implement rich, responsive UI in React and TypeScript to build refined and elegant user interfaces.\n\nWork across the Superhuman product suite - Go, Mail, Docs, Grammarly, or enterprise..\n\nTarget high availability for consumer and enterprise customers.\n\nTackle hard interaction design problems: streaming content, complex state management, and multi-surface interactions.\n\nCollaborate widely with Product, Design, and ML/AI teams to translate AI capabilities into intuitive user experiences..\n\nContribute to an engineering culture with a strong emphasis on documentation, testing, and user experience.\n\nMentor and grow junior engineers on the team.\n\nQualifications\n7 years of experience in front-end development, with expert-level knowledge of TypeScript (and/or JavaScript), HTML, and CSS, extensive experience with ReactJS (or similar UI frameworks) and modern web client development and testing tools.\n\nExcellent software engineering fundamentals, including knowledge of algorithms and data structures.\n\nComfort working with AI-powered features - whether that's building UI for LLM-generated content, streaming responses, or agentic workflows. Prior experience integrating AI/ML into product surfaces is a plus.\n\nFluency with AI coding tools (Copilot, Cursor, Claude Code, etc.) and a point of view on how they change the way teams build software.\n\nExperience with browser extensions, cross-platform web clients, or shipping front-end code across multiple surfaces (web, desktop, mobile) is a plus.\n\nDeep understanding of continuous integration and delivery methods.\n\nStrong product instincts - you care about the end-user experience and strive to ensure high quality.\n\nAbility to work independently with minimal guidance, proactively manage priorities across multiple projects, and collaborate effectively with cross-functional teams.\n\nWe invite you to share your knowledge, experience, and goals with us to help us find the best team match for you. Tell us your superpower!\nCompensation and Benefits\nSuperhuman offers all team members competitive pay along with a benefits package encompassing the following and more:\nExcellent health care (including a wide range of medical, dental, vision, mental health, and fertility benefits)\n\nDisability and life insurance options\n\n401(k) and RRSP matching\n\nPaid parental leave\n\n20 days of paid time off per year, 12 days of paid holidays per year, two floating holidays per year, and flexible sick time\n\nGenerous stipends (including those for caregiving, pet care, wellness, your home office, and more)\n\nAnnual professional development budget and opportunities\n\nSuperhuman takes a market-based approach to compensation, which means base pay may vary depending on your location.
