We combine strategic thinking, customer‑centric service design, and agile engineering practices to accelerate innovation in a tech‑driven world.

• Why Join Our Digital & Data Community
• Join our Digital & Data team working alongside product, design and a wide range of other experts and cross‑disciplinary teams to bring ideas to life through innovative software solutions.
• Grow a flexible and unique career within a trust‑based, inclusive environment that values excellence, innovation, and curiosity.

You have the option to progress with us on a technical career track.

• Hybrid working – we expect you to be in the office or on client site a minimum of 2 days per week.
• Work on a broad variety of projects and tech stacks for clients across seven sectors – no project is ever the same.
• Join other experts within our supportive and collaborative tech community through knowledge‑sharing and peer‑level support, coaching and mentoring.
• Deepen your expertise through our culture of learning and growth – you’ll have budget to take courses (technical and non‑technical training) and gain certifications.
• What You Can Expect
• Work to agile best practices and cross‑functionally with multiple teams and stakeholders.

You’ll be using your technical skills to problem‑solve with our clients, as well as working on internal projects.

• Live in‑person whiteboarding sessions to problem‑solve as a team, alongside asynchronous communication on Teams.
• Hybrid working with the team on client site or in our office a minimum of two days per week.

However, the actual time you spend and where you spend it will vary by role or assignment, including up to 5 days per week on a client site.

• An environment that deeply cares about its values.
• We’re hands‑on with emerging technologies – exploring what works, what scales, and what’s next.
• Experimenting with Generative AI frameworks and tools such as Lang Chain, Llama Index, Hugging Face, and APIs from Open AI and Anthropic.
• Building retrieval‑augmented generation (RAG) prototypes with vector stores and knowledge graphs.
• Developing and testing agentic architectures through our own Genie Platform – enabling AI agents that reason, retrieve, and act across systems.
• Exploring LLMOps, evaluation tools, and model observability platforms like Tru Lens and Lang Smith.
• Deploying solutions on modern cloud and Dev Ops environments (AWS, Azure, GCP) – but always choosing the right tools for the problem at hand.
• Constantly learning, testing, and sharing findings across our internal AI community.

Qualifications
