About Us:

THE EXTRAORDINARY STORY OF 809 CONNECTED BUSINESSES

Digital and Innovation in Westminster City Council is a world of extraordinary stories, where creative and enterprising people put local residents and businesses first.

Today, Westminster is the most connected borough in London. But, when David joined us in the mid-2010s, small businesses were still struggling to get connected to fibre. Without gigabit-capable broadband, some companies even resorted to biking memory sticks around the city, simply to share files with clients.

Although still in a junior role, David took the initiative and successfully made the business case for £2.8 million of European funding to support connectivity for small businesses across Westminster. Feedback from businesses has been overwhelmingly positive as the project has enhanced their communications with clients. The new connectivity allows them to make video calls and work remotely. As the pandemic hit and many more people needed to work from home, it became clear just how vital this investment had been.

Fast-forward a few years. Westminster is leading the way for connectivity, as a result of the project businesses are thriving, and David is heading up a service of his own responsible for delivery of the Smart City strategy.

The Role:

As a Lead Software Engineer, you can make your own powerful contribution to people across Westminster. Joining the council’s newly established AI Innovation Hub, you’ll act as the senior technical authority for AI agents — owning the most complex agent builds, setting the patterns the rest of the organisation follows, and running the Agent Ops operating model that keeps the council’s agent estate safe.

Your day-to-day will be varied and dynamic, including everything from designing resident-facing assistants and internal staff productivity agents, to responding to incidents and ensuring governance processes are followed. Acting as a mentor to less technical agent builders, you’ll raise the technical floor across the organisation, building community, sharing knowledge and supporting council teams to harness AI to deliver better outcomes for residents. 

Please refer to the Job Description for more information.

About You:

An established professional with demonstrable experience designing and delivering AI agents or AI-enabled automation in a production setting, you’ll bring hands-on experience of Microsoft Copilot Studio and the Power Platform. You may have worked in a complex or regulated organisation in the past, and will be confident monitoring and evaluating AI agents, controlling cost, responding to incidents and applying an AgentOps-style lifecycle. You’ll also have a strong understanding of the following:

• Agentic patterns.
• Prompt design, scripting and programming for integration and automation.
• AI safety, Responsible AI, prompt-injection defences, data governance and privacy.
• APIs, JSON/XML, OAuth, Microsoft Graph, custom connectors, and Dataverse data modelling. 

As a leader, you’ll be motivating and supportive, setting a high-bar that inspires others to learn, grow and develop their own skillsets. On a personal level, you’ll have the ability to communicate technical concepts to non-technical audiences, strong problem-solving and analytical skills and a commitment to user-centred design and inclusive service delivery. This is a fantastic opportunity to join an innovative, supportive team, and to supercharge your career in the process.
