Full Stack Engineer (Front End heavy React TypeScript and/or Next.js)

We're looking to speak to Front End heavy, senior fullstack engineers, as our client has launched it's industry's first legal AI Agent and have seen phenomenal growth in both revenue and usage in the last 18 months.

With the recent release of many Large Language Models (LLMs), such as OpenAI's GPT-5 and o3, we've continued to adopt bleeding edge frontier models. This is an opportunity for someone who is passionate about learning how to utilise this in production use cases.

You'll own the end-to-end design and development of key features of our web application along with the underlying services that support it. You'll be joining a small, dynamic and fast-paced team with a focus on quality, usability and impact. You'll be involved in every stage of the development life cycle; from discovery and design, through implementation to deployment, maintenance and continuous improvement. You will be supported by a cross-functional, collaborative and growing team in delivering an impactful product, initially to lawyers and then to a wider set of B2B customers.

You'll get a chance to:

• Take ownership of key technology decisions and lay the groundwork for the company's ambitious growth plans
• Influence how we structure our Front End architecture to optimise for scale, speed of iteration and quality
• Shape product direction and influence beyond the technical implementation into how we go about solving real customer pain
• Collaborate with a cross functional team (an AI product manager, legal domain experts, AI engineers and software engineers) to ideate, experiment, prototype and ship your (and the teams ideas) into the hands of the customer
• Champion quality and reuse across the product and the codebase
• Collaborate with individuals across the business to ensure the features you develop have real business impact for customers and actually move key business metrics as we design and build a brand new product that doesn't yet exist in the market
• Participate in architecture and code reviews to continuously improve the quality, maintainability, security and scalability of our applications

You should apply if you:

• Have a strong background in Front End development - ideally React, TypeScript and/or Next.j
• Have experience with Backend development - ideally Python
• Experience working with LLM's and OpenAI's API in particular
• Have worked as a Product Engineer or worn a product hat in the past
• Care about solving the technically challenging problems we're tackling for our customers
• Value shipping early and often to get customer feedback and then iterating quickly to improve the product
• Have excellent verbal and written communication skills in English
• Have a proven track record of building user-facing products and have the ability to put yourself in the shoes of the customer
