Lead Software Engineer - D365 & AI

Lead Software Engineer

We're looking for a visionary Lead Software Engineer to drive the evolution of our enterprise-wide strategic platform. This is more than a technical role—it's a leadership opportunity to shape architecture, inspire teams, and deliver transformative solutions using Microsoft Power Platform, Dynamics 365 (D365) and Azure.

As a key technical leader, you'll set the direction for scalable, resilient systems across a modern tech stack including Azure, JavaScript/TypeScript, and front-end frameworks. You'll foster collaboration across Agile squads, champion engineering excellence, and mentor the next generation of developers.

About You

• A proven track record of leading high-performing engineering teams with clarity and purpose
• Strategic thinking in defining architecture and development best practices
• Ownership of the full development lifecycle—from planning to delivery—with a focus on performance and reliability
• A collaborative mindset, working seamlessly with design, QA, product, and engineering leadership
• Passion for clean, maintainable, and well-tested code
• Experience implementing automation frameworks and conducting rigorous code reviews
• Confidence in leading technical discussions and aligning squads to strategic goals
• A commitment to continuous improvement, modernisation, and DevOps excellence
• A drive to simplify and accelerate delivery of resilient software

What Do I Need To Be Successful?

• 8+ years of software engineering experience, with a strong focus on enterprise applications
• Proven expertise in Power Platform and Dynamics 365 (D365), including model-driven apps, plugin development, and PCF.
• Demonstrated experience leading software engineering teams, including mentoring, code reviews, and technical direction.
• Deep knowledge of Azure PaaS components (Logic Apps, Functions) and integration practices.
• Proficiency in C#, JavaScript/TypeScript, Git, Visual Studio, and VS Code.
• Experience with Azure DevOps and CI/CD pipelines.
• Familiarity with AI tools such as AI Foundry, Azure Document Intelligence or Power Platform AI Builder.
• Bonus: Experience with React, TypeScript, and/or VueJS.

You'll also be confident in:

• Leading solution design and technical delivery
• Driving code quality and engineering best practices
• Troubleshooting and resolving complex production issues
• Creating and maintaining clear, comprehensive documentation
