Job description

Location:Edinburgh (Hybrid: 3 days in-office, 2 remote)

Mission:Design and deliver world-class product experiences that harness the power of LLMs and redefine how legal teams work. You’ll build core features, influence architectural decisions, and collaborate closely with cross-functional teammates to ship fast, iterate, and make an impact.

Key Responsibilities:

• Own end-to-end product features across frontend and backend

• Collaborate with design, product, and legal engineering to deliver polished, AI-native workflows

• Help architect and evolve our codebase for performance, scale, and developer experience

• Contribute to shaping engineering practices, tooling, and team culture

Experience & Qualifications:

• 4+ years of experience building high-impact web products

• Strong knowledge of core technologies like React, Next.js, Tailwind, TypeScript; backend experience (e.g. Python, Node.js, AWS) is a bonus

• Deep product instincts—you care about clean UI, intuitive UX, and building for user outcomes

• Practical understanding of security, scalability, and technical debt in fast-moving environments

• Interest in AI/LLMs and building AI-native user experiences

What We Offer:

• A high-trust environment with meaningful ownership over what you build

• Real-world product challenges—security, performance, usability—at the heart of legal workflows

• A tight-knit team of engineers, designers, legal minds, and builders

• Competitive salary, meaningful equity, and the opportunity to shape an early product and team

Who You Are:You might have built at an early-stage startup or scaled features at a high-growth company. You’re fluent in full-stack thinking, but even more fluent in user empathy. You’re excited by the pace and ambiguity of a company still forming its best practices—and you love helping define them.

Bonus:Experience working on internal legal tools, legal ops software, or compliance platforms. Curiosity around prompt engineering, user intent modeling, or AI reasoning is also a plus.
