Job Description

MORE THAN YOU EXPECTED

Grant Thornton UK LLP is part of a global network of independent audit, tax and advisory firms, made up of some 58,000 people in over 135 countries. We're a team of independent thinkers who put quality, inclusion and integrity first. All around the world we bring a different experience to our clients. A better experience. One that delivers the expertise they need in a way that goes beyond. Personal, proactive, and agile. That's Grant Thornton.

NEW GROUND WON'T BREAK ITSELF

Every day our teams help people in businesses and communities to do what is right and achieve their goals.

We're hiring Senior Engineers into our team, based in the North of England. You'll be a hands‑on individual contributor, enabling our client‑facing teams, building real solutions that create measurable value, concentrating your engineering effort on solving in our GenAI platform, or building around and outside it when needed.

We're happy to talk flexible working and consider reduced hours and job shares, we'll support you to balance your work and life.

A look into the role

As a Senior Engineer within our team:

• You'll work within a forward deployed engineering team or a delivery pod aligned to one of our service lines, alongside a product manager and under the technical direction of a Lead Engineer.
• The work spans the full stack of what engineering needs to do around a GenAI platform: solving problems natively, backend plumbing, API integrations, MCP server builds, and data connections.
• Working in our GenAI platform doesn't always mean writing code. Often it means applying engineering judgement to solve problems natively, designing the right architecture, the right integration, the right data flow, directly within the platform itself.
• Knowing which mode the problem calls for is part of the craft here.
• At Senior Engineer level, you'll own your delivery end‑to‑end. You translate business need into solutions and technical design, and work individually or as part of the team to solve those in the best way at pace.
• You're fluent across AI‑native engineering from building natively in the platform, using AI tooling to accelerate your own craft, and taking coalface experiments through to production‑grade operationalised solutions.
• At Senior Engineer level, that fluency is already there and you apply it independently.

Knowing you're right for us

Joining us as a Senior Engineer, the minimum criteria you'll need is:

• At Senior Engineer level you have a track record of owning delivery end‑to‑end in a team‑based model. You've shipped production software and can speak to the decisions you made.
• You have real depth in backend and integration engineering using Python or C# .Net, and genuine judgement about when to solve natively in the platform and when bespoke engineering is the right call.
• It would be great if you had some of the following skills, but don't worry if you don't tick every box, we'll help you develop along the way.
• Across both levels familiarity with Azure and Microsoft 365 is an advantage.
• Hands‑on experience with LLM integration patterns, MCP tooling, and AI‑enabled or agentic development environments is genuinely valued.
• AI and LLM experience - you're comfortable using GenAI tools such as Copilot, Claude or ChatGPT.

Knowing we're right for you

Embracing uniqueness, the culture at Grant Thornton thrives on the contributions of all our people, we never settle for what is easy, we look beyond to deliver the right thing, for everyone. Building an inclusive culture, where we value difference and respect our colleagues helps our people to perform at the best of their ability and realise their potential.

Our open and accessible culture means you'll interact with leaders who are interested in you and everything you bring to our firm. The things that set you apart, we value them. That's why we give you the freedom to bring your whole self to work and pursue your passions inside and outside of work.

Beyond the job

Life is more than work. The things you do, and the people you're with outside of work matter, that's why we're happy to look at flexible working options for all our roles, and we'll always do our best to keep your work and life in balance.

The impact you can make here will go far beyond your day job. From secondments, to fundraising for local charities, or investing in entrepreneurs in the developing world, you'll be giving back to society. It's that drive to do the right thing that runs through our every move, grounded in our firm's values - purposefully driven, actively curious and candid but kind.

We're looking for people who want to contribute, spark fresh ideas and go beyond expectations. People who want to be able to proudly do what's right, for the firm, our clients, our people and themselves. It's how it should be.
