MORELA

Application Developer

AI Applications & Power BI | Holborn, London

Morela is proud to be supporting a London-based AI analytics business in the search for an Application Developer. This is a permanent role based at the client’s office in Holborn, Central London, four days a week (Monday to Thursday), with a salary of £75,000 plus benefits. Candidates must have the right to work in the UK.

About the Client

Our client runs an AI customer growth platform that helps some of the UK’s best-known consumer brands get far more value from their first-party customer data. Their clients include household-name retailers and financial services businesses with customer bases running into the millions.

The platform shows where growth in a customer base is coming from, where it is going, where it is leaking and which behaviours drive it, then projects that forward. Boards get a forward-looking view of their customers instead of a historic one, and can test interventions against it. It has grown into a management system for customer value growth, sitting in the gap between high-level strategy consultancies and marketing-led CRM firms.

The business is founder-funded and has built its platform with a deliberately lean, senior team. It is now investing in the people and practices to scale, including a move to forward-deployed implementation teams from next year. It is a genuine chance to join early and shape how the business grows.

The Role

This is a priority hire. The client is moving its product from Power BI dashboards to AI-enabled web applications, and this role sits right at the centre of that shift.

You will keep existing Power BI deployments running smoothly for current clients while building the new application layer that replaces them, then help migrate those clients across. Alongside the build work, you will work directly with client technical and security teams to get the platform deployed in their environments.

Responsibilities

• Maintain and enhance existing Power BI reports and models, including DAX, for current clients during the migration.
• Design and build the new web application presentation layer for the platform.
• Use modern AI tooling and integrate with the agents the business is building into its product.
• Plan and deliver client migrations from Power BI to the new applications.
• Work with client IT and security teams on infrastructure requirements, security reviews and DPIA sign-off to deploy the platform in their environment.
• Get client data flowing into the platform so insight can be presented back to them.
• Work closely with the data scientists and engineers to turn models and data into applications clients use every day.

Essential Requirements

• Strong hands-on Power BI experience, including DAX and data modelling.
• Commercial experience building web applications (front end and back end).
• Practical experience with current AI and LLM tooling, and an interest in agent-based applications.
• Comfortable in client-facing technical conversations, including with IT and security stakeholders.
• Able to balance supporting live clients with building new product.

Desirable Experience

• Experience migrating clients or users from BI tools to bespoke applications.
• Experience deploying software into client-hosted or enterprise cloud environments.
• Knowledge of data security, privacy and DPIA processes.
• Experience in a forward-deployed, consultancy or solutions engineering role.
• Experience with customer, marketing or CRM data.

Working Environment

You will be based in Holborn four days a week, Monday to Thursday, as part of a small, senior team with direct access to leadership. Clients are currently supported mainly remotely, with on-site visits when needed, and the business plans to move to forward-deployed implementation teams from next year. It is a hands-on role where your work is visible and shapes the product.
