Location: London (Hybrid with travel to London expected circa 3x per week) Type: Full-time Compensation: Competitive salary equity Stage: Pre-seed, funded by a leading UK law firm About Us We’re building a next-generation platform redefining how early-stage companies manage legal processes. Backed by a top UK law firm, we’re on a mission to simplify legals through an Agentic AI-powered platform that blends automation, reasoning, and legal expertise. We’re currently operating in stealth while assembling a founding team that will set the standard for the future of legal technology. The Role We’re looking for a CTO/ Founding Engineer to join us as we design, build, and scale the first version of our platform, from product architecture to deployment. This is an opportunity to help define the technical culture, make core product decisions, and shape a company that’s backed by legal, financial, and strategic firepower from day one. You’ll be hands-on early, shipping code, building the agentic AI framework, and iterating with real users. Over time, you’ll build and lead a world-class engineering team. What You’ll Do Lead technical strategy and architecture for the platform from inception. Build and deploy the MVP, a modular AI-driven legal system. Integrate LLMs, legal logic engines, and data layers into a cohesive product experience. Define best practices for data security, scalability, and compliance. Collaborate with founders on product vision, UX, and roadmap prioritisation. Recruit and mentor early engineering hires as the company scales. Work closely with legal and AI partners to ensure performance, reliability, and innovation. Who You Are A strong full-stack or backend engineer with experience taking products from zero to one. Fluent in modern frameworks (e.g. TypeScript, Next.js, Python/FastAPI, Postgres, AWS/GCP). Deep interest in applied AI — ideally with hands-on experience integrating LLMs or agent frameworks (e.g. LangChain, OpenAI API, Anthropic, etc.). Pragmatic: you balance speed, quality, and maintainability. Curious and product-minded: you care as much about user experience as elegant code. Entrepreneurial: comfortable with ambiguity and early-stage chaos, eager to build from scratch. Interested in legal tech, fintech, or SaaS infrastructure or simply in solving complex, often unsexy problems that matter. Nice to Have Prior startup experience as a founding engineer or early technical lead. Experience building AI-first or automation-heavy products. Understanding of legal, compliance, or workflow automation systems. Experience building scalable architectures in multi-tenant SaaS. What You’ll Get Competitive Salary Founding-level equity and ownership in a funded company. Freedom to shape product, architecture, and team. Partnership with a seasoned founding team with deep legal, strategic, and commercial expertise. Opportunity to define the technology behind one of the UK’s most ambitious legal AI ventures. How to Apply If you’re an ambitious engineer who wants to build the future of legal tech from day zero, we’d love to hear from you.
