You’ll play a key role in building and scaling modern, intelligent web applications that support data-driven workflows across the organization.

Your work will directly impact how teams interact with information by delivering secure, high performance products that are intuitive and reliable including AI-assisted features for document analysis and automation.

In this role, you will:

• Design, build, test and deploy full-stack web applications using modern React-based frameworks such as Next.js.
• Develop scalable frontend experiences using Tailwind CSS and component-driven UI systems.
• Build backend services and APIs using Node.js and TypeScript to support application and integration workflows.
• Design, query and optimise relational databases (PostgreSQL), including schema design, migrations and performance considerations.
• Implement secure authentication, authorisation and role-based access controls.
• Integrate external systems and services via REST APIs, webhooks and event-driven workflows.
• Implement AI-powered features using Large Language Models (LLMs) for email parsing, document analysis and structured data extraction.
• Manage application data fetching, caching and state consistency across client and server layers.
• Participate in code reviews, testing and deployment pipelines to ensure quality, security and reliability.
• Monitor application performance, troubleshoot issues and contribute to continuous improvements.
• Maintain technical documentation, architectural decisions and development standards.

Your Background

We’re looking for someone who thrives in building end-to-end digital products, a problem solver who is comfortable working across frontend, backend and cloud-based systems.

You enjoy turning complex requirements into well-designed, maintainable solutions and take pride in delivering systems that scale.

You’ll bring:

• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• 4 - 6 years of experience in full-stack web development.
• Strong experience with React and modern frameworks such as Next.js.
• Proficiency in TypeScript and modern JavaScript development practices.
• Hands-on experience building backend logic using Node.js.
• Solid experience working with relational databases such as PostgreSQL, including data modelling and optimisation.
• Experience implementing authentication, authorisation and secure data access patterns.
• Familiarity with modern data-fetching and state-management approaches (e.g., React Query or equivalents).
• Experience with schema-based validation and structured data modelling.
• Exposure to cloud-based deployment platforms and CI/CD workflows.
• Practical experience integrating or consuming AI/LLM APIs will be highly regarded.

What’s on offer

• The opportunity to work on modern, business-critical platforms with real-world impact.
• A collaborative, technically strong engineering environment that values clean architecture and thoughtful execution.
• Exposure to cutting-edge web frameworks, AI-enabled workflows and cloud-native platforms.
• The ability to influence technical direction, tooling and engineering standards as platforms evolve.
• Flexible working arrangements and a culture that values ownership, accountability and continuous learning.
• Long term growth opportunities across multiple products and technology domains.
