We need a visionary Full-Stack Engineer (Front-End Leaning) to define how humans interact with the next generation of AI.\nThe Role: Full-Stack Engineer\nYou’ll be joining the leanest, most talent-dense engineering team in London. Chat is a starting point, but it’s not the destination. You aren't just building dashboards; you are inventing the UI/UX paradigms for AI-assisted legal work - interfaces that didn't exist 18 months ago.\nWhat you’ll own:\nThe Interface of AI: Lead the design and development of our user interface, moving beyond simple chat to create intuitive, high-performance tools for complex IP workflows.\n\nProduct Evolution: Rapidly prototype and ship features based on direct customer feedback from the world’s top law firms.\n\nEnd-to-End Delivery: While front-end is your forte, you’ll dive into the back-end to ensure features are seamless, robust, and deployed at pace.\n\nWYSIWYG Innovation: Own the integration and customization of advanced document editors (TinyMCE/CKEditor) to handle the heavy-duty drafting requirements of patent attorneys.\n\nEngineering Culture: As an early hire, you will help set the bar for code quality, speed, and design excellence across the entire stack.\n\nAbout Solve Intelligence\nWe’re the fastest-growing startup transforming the IP industry.\nTraction: 20-30% MoM revenue growth; selling to 700+ global IP teams (DLA Piper, tech boutiques, and global enterprises).\n\nProven Value: Users report 50-90% efficiency gains using our AI platform.\n\nBacking: Recently featured in Sifted following our $40M Series B announcement, bringing our total funding to $55M from elite investors including Y Combinator, 20VC, Visionaries and others.\n\nYour Team\nYou’ll work directly with a founding team of AI PhDs and systems experts:\nSanj (CRO): PhD in AI (Gatsby Unit, UCL), ex-Huawei R&D, former lead at Magic Carpet AI (acquired).\n\nChris (CEO): PhD in AI (UCL), published researcher, ex-Dyson and Alan Turing Institute.\n\nAngus (CTO): MEng Computer Science, ex-Qualcomm and Coremont (Brevan Howard)\n\nWho You Are\nWe are a high-performance culture of \"hackers\" and builders.\nObsessed with Speed: You believe that shipping today is better than perfection next month. You iterate in days, not weeks.\n\nHuman-Centric: You understand that world-class AI is useless without a clean, intuitive interface that people actually enjoy using.\n\nExtreme Ownership: You take pride in every pixel and every API call, ensuring a \"five nines\" level of reliability and polish.\n\nDriven & Humble: You are willing to go the extra mile (including the occasional late night or weekend) to ensure our users are blown away.\n\nWhat You Bring\nMust-Haves:\nExperience: Professional experience building and scaling complex web applications.\n\nTypeScript/React Expert: Deep mastery of modern front-end frameworks and state management.\n\nFull-Stack Fluency: Comfortable navigating back-end systems and full-stack frameworks to get the job done.\n\nProduct Intuition: A track record of turning vague user needs into concrete, beautiful UI.\n\nPreferred & Nice-to-Haves:\nPython Mastery: Experience with our back-end language of choice.\n\nEditor Expertise: Experience working with WYSIWYG APIs (TinyMCE, CKEditor, Prosemirror).\n\nDesign Skills: Proficiency in Figma and a \"good eye\" for modern aesthetics.\n\nDatabase Knowledge: Comfort with Postgres and data modeling.\n\nWhat We Offer\nCompetitive Salary + Significant Equity: We want you to have true ownership in the success of the company.\n\nFounding Impact: You will have a direct hand in every product and architectural decision we make.\n\nSupport: Full visa sponsorship and private medical insurance.\n\nThe Environment: Free meals and a seat at the table with an incredibly smart, ambitious team.\n\nReady to build the face of the future of AI?
