Make an Impact at RSM UK. RSM has established the AI Lab – a strategic team driving the responsible adoption of AI across the firm. The Senior AI Software Engineer is a core technical role within the AI Lab. This person helps design and build the foundation that AI solutions are built on — bringing engineering depth, an eye for systems thinking, and a commitment to quality that raises the bar for the whole team.

You’ll make an impact by:

• Contributing to system design and feasibility assessments for new AI initiatives, helping evaluate technical approaches, surface risks, and shape solution direction ahead of development.
• Helping maintain and evolve development and coding standards across the Lab, ensuring AI work produced by the firm is consistent, clean, and built to last.
• Implementing enterprise integration patterns that connect AI solutions to RSM's wider technology ecosystem in a secure and scalable way.
• Building and maintaining automation frameworks that improve the speed and reliability of development, testing, and deployment.
• Applying appropriate architectural patterns and scalability models when designing solutions, with an awareness of how choices made today affect maintainability tomorrow.
• Participating in technical reviews, offering constructive input on designs and code produced by peers and contributing to a culture of engineering rigour.
• Designing and developing AI solutions end‑to‑end across the Lab's core platforms — Copilot Studio, Azure AI Foundry, Intellixcore, and more — from initial design through to production delivery.
• Producing clear technical documentation, architectural diagrams, and reusable assets that help the wider team build confidently and consistently.
• Supporting junior engineers and graduates with day‑to‑day technical guidance, code review, and practical problem‑solving.

What we are looking for:

The ideal candidate is a capable, hands‑on engineer with a growing interest in how AI systems are designed and structured at scale — someone who takes quality seriously and brings considered thinking to every build. Key attributes include:

• Solid experience designing and delivering AI or data‑driven solutions in a professional context, with involvement in architectural or system‑level decisions.
• Working knowledge of enterprise AI platforms — ideally Copilot Studio, Azure AI Foundry, or Intellixcore — or equivalent cloud and AI tooling, with the ability to get up to speed quickly.
• A good grounding in software engineering principles including system design, API and integration patterns, and security fundamentals.
• Solid programming skills, with practical experience in Python and SQL used in AI and data engineering contexts; comfortable working across both code‑first and low‑code platforms.
• Comfortable working within governance or compliance‑aware environments, understanding the importance of building responsibly without losing momentum.
• Ability to produce technical documentation and diagrams that are accessible to both engineering colleagues and non‑technical audiences.
• Strong communication and collaboration skills, with the confidence to raise technical concerns, contribute to design discussions, and support teammates effectively.

What we can offer you:

We recognise that our people are our most important assets. That’s why we offer a flexible reward and benefits package that will help you have fulfilling experience, both in and out of work.

• Hybrid and Flexible working
• 26 Days Holiday (with the option of purchasing additional days)
