Job Specifications

THE BIG PICTURE:

Bernadette is the experience arm of the VCCP Partnership. We invent, make and iterate products and services for our clients across all areas of their digital eco-system.

We are 70 strong and are full service within our own right. We have specialists across UX, Design and Motion, Technology, Engineering, Content and Comms, Project Management, Data, Strategy and Ops. All dedicated to creating customer experiences worth talking about. Check out what we do here.

The VCCP Partnership as a whole is an integrated communications agency set up in 2002 by Charles (V), Rooney (C), Adrian (C) and Ian (P), who founded the agency on the principles of simplicity, collaboration, un-preciousness and integration around ideas rather than channels. Their founding client was BT Cellnet, now more commonly known as O2 and the most awarded brand in IPA effectiveness history.

Across the Partnership, we work with a broad spectrum of clients such as O2, CompareTheMarket, easyJet, Paddy Power, Dominos and Cadbury.

OUR CULTURE:

Bernadette has a unique culture, and we are looking for people who will make a positive contribution to this, therefore the candidate must have the following attributes:

A collaborative nature
An entrepreneurial spirit
Take pride in their work
Have an honest approach
Be un-precious and be able to recognise that a good idea can come from anywhere
Take responsibility

OUR PURPOSE:

At Bernadette, we’re on a mission to bridge the gap between ‘digital strategy’ and the execution of ‘digital experiences’ to make breakthrough products & services. That includes opening new categories and formats, delivering groundbreaking customer interactions, or generating long-term customer advocacy - across the whole digital ecosystem. We’re here to make a difference.

We make breakthrough digital products and services which set new standards for everyone to follow, are indispensable and you can’t imagine life without them. We also deliver digital communication assets and activations for integrated campaigns for all of our VCCP clients.

WHAT WE’RE LOOKING FOR

This role focuses on building the server-side logic and integration layers for complex digital products. You will develop robust C# codebases that power traditional web applications as well as new AI-driven workflows and RAG (Retrieval-Augmented Generation) implementations.

Key Responsibilities

Develop and maintain high-performance services using C# and ASP.NET Core.
Implement asynchronous patterns and background processing using Hangfire.
Integrate AI model APIs into existing backend architectures.
Address and mitigate security challenges across the full application stack.

Required Skills and Experience

Deep expertise in C#, ASP.NET Core, and dependency injection.
Strong understanding of async/await patterns.
Familiarity with build tooling and pipelines.
Experience with EFCore or similar.
Proficiency with Git/GitHub and working in agile teams.

Beneficial

Experience with performance and load testing for high-traffic applications.
Practical knowledge of Azure DevOps pipelines and containerization (Docker).
Experience writing and maintaining E2E tests using Playwright.
