Summary Generated by Built In

At Solve Intelligence, we’re building the AI-powered infrastructure for the global Intellectual Property landscape. We need a visionary Full-Stack Engineer (Front-End Leaning) to define how humans interact with the next generation of AI.

🏗️ The Role: Full-Stack Engineer

You’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.

What you’ll own:

  • The 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.

  • Product Evolution: Rapidly prototype and ship features based on direct customer feedback from the world’s top law firms.

  • End-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.

  • WYSIWYG Innovation: Own the integration and customization of advanced document editors (TinyMCE/CKEditor) to handle the heavy-duty drafting requirements of patent attorneys.

  • Engineering Culture: As a founding hire, you will help set the bar for code quality, speed, and design excellence across the entire stack.

💡 About Solve Intelligence

We’re the fastest-growing startup transforming the IP industry.

  • Traction: 20-30% MoM revenue growth; selling to 600+ global IP teams (DLA Piper, tech boutiques, and global enterprises).

  • Proven Value: Users report 50-90% efficiency gains using our AI platform.

  • Backing: 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.

👋 Your Team

You’ll work directly with a founding team of AI PhDs and systems experts:

  • Sanj (CRO): PhD in AI (Gatsby Unit, UCL), ex-Huawei R&D, former lead at Magic Carpet AI (acquired).

  • Chris (CEO): PhD in AI (UCL), published researcher, ex-Dyson and Alan Turing Institute.

  • Angus (CTO): MEng Computer Science, ex-Qualcomm and Coremont (Brevan Howard)

🚀 Who You Are

We are a high-performance culture of "hackers" and builders.

  • Obsessed with Speed: You believe that shipping today is better than perfection next month. You iterate in days, not weeks.

  • Human-Centric: You understand that world-class AI is useless without a clean, intuitive interface that people actually enjoy using.

  • Extreme Ownership: You take pride in every pixel and every API call, ensuring a "five nines" level of reliability and polish.

  • Driven & Humble: You are willing to go the extra mile (including the occasional late night or weekend) to ensure our users are blown away.

🛠️ What You Bring

Must-Haves:

  • Experience: Professional experience building and scaling complex web applications.

  • TypeScript/React Expert: Deep mastery of modern front-end frameworks and state management.

  • Full-Stack Fluency: Comfortable navigating back-end systems and full-stack frameworks to get the job done.

  • Product Intuition: A track record of turning vague user needs into concrete, beautiful UI.

Preferred & Nice-to-Haves:

  • Python Mastery: Experience with our back-end language of choice.

  • Editor Expertise: Experience working with WYSIWYG APIs (TinyMCE, CKEditor, Prosemirror).

  • Design Skills: Proficiency in Figma and a "good eye" for modern aesthetics.

  • Database Knowledge: Comfort with Postgres and data modeling.

🎁 What We Offer

  • Competitive Salary + Significant Equity: We want you to have true ownership in the success of the company.

  • Founding Impact: You will have a direct hand in every product and architectural decision we make.

  • Support: Full visa sponsorship and private medical insurance.

  • The Environment: Free meals and a seat at the table with an incredibly smart, ambitious team.
