The Vision

Circuit Creative is a newly formed agency that is part of the Gilbert & Rose holdings group; we are the engine room for their property brands along with working with external clients. We are looking for a passionate Lead Full Stack Developer to work with us on taking the business to the next level. You won’t just be maintaining websites; you will be building a proprietary ecosystem.

From developing bespoke client portals and integrating phone systems for deep behavioural analytics to pioneering AI-driven automation that allows our business to operate 24/7, you will be the architect of our digital future.

The Role

As the Lead Developer, you will head the development for our core brands:

  • Gilbert & Rose: Building a bespoke “all-in-one” client portal, internal dashboards & intranets.
  • Niche Homes: Developing scalable systems to take a luxury real estate brand to a national audience.
  • Circuit Creative: Leading web development for external clients and internal group projects.

Key Responsibilities

  • Ecosystem Development: Work with us to build bespoke React/Node.js framework.
  • API & Integration: Build and manage complex integrations between our CRM, Webex telephony, and bespoke front-end applications.
  • Data & Analytics: Develop internal dashboards and “league tables” to track performance and buyer behaviour.
  • AI & Automation: Architect and implement AI agents and automated workflows to create an autonomous, 24-hour business cycle.
  • Product Leadership: Work closely with the marketing and senior leadership teams to translate business goals into technical roadmaps.

Technical Requirements

Essential:

  • Front-end: Strong knowledge of React and Next.js
  • Back-end: Strong experience with Node.js or PHP (to manage/migrate existing systems).
  • Databases: Proficiency in SQL (MySQL/PostgreSQL) and experience with NoSQL (MongoDB) for flexible data handling.
  • API Architecture: Extensive experience working with RESTful APIs and Webhooks (GraphQL a bonus).
  • Responsive Design: A “mobile-first” mindset for high-end user experiences.

Desirable:

  • Telephony/Webex: Experience with Webex SDKs or VoIP integrations.
  • AI/ML: Familiarity with OpenAI API, LangChain, or building autonomous AI agents.
  • DevOps: Experience with AWS/Azure and CI/CD pipelines.

About You

Entrepreneurial: You don’t just want a “ticket” to work on; you want to build a product that changes an industry.

Strategic: You can see the big picture and understand how a technical decision today impacts the ability to scale further tomorrow.

Ambitious: You are looking for a role where you can grow into the Head of Technology for a multi-brand group.
