About the Role

We're looking to speak to frontend heavy, senior fullstack engineers, as we've launched the industry’s first legal AI Agent and have seen phenomenal growth in both revenue and usage in the last 18 months. [Employer hidden] Copilot is a new product which is delivering much needed automation in Real Estate transactions across the country and internationally, with a view to transforming the way property is transacted. We have a successful existing product which helps real estate professionals extract key information & create reports from legal documents. We’re evolving this product to add further value to our user base. 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.

  • 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.
  • Security is everyone’s responsibility at [Employer hidden]. We ask all team members to follow our security policies, complete regular awareness training, and handle sensitive data with care in line with ISO 27001 standards.
  • Spot something unusual? Reporting risks or incidents quickly helps us maintain the strong culture of security and compliance we all depend on.
