Making a difference isn’t just our purpose, it’s what motivates our people every day. For us, work is not about ticking a box. It’s about knowing that it matters. We make a meaningful difference every day by making it easier for our customers to focus on what matters in their lives. 

At McMillan Shakespeare, we’re modernising systems and redefining how financial services technology delivers value at scale.

We’re looking for a Senior Software Engineer who thrives on ownership, architectural influence, and lifting engineering standards. This is for someone already operating at a senior level who wants to shape the future of our platforms, not just maintain them.

You’ll have proven experience designing solutions, writing high-quality production code, troubleshooting complex technical issues and working across the full software development lifecycle. If you’re passionate about modern architecture, AI-driven solutions and improving BAU systems, this is a high-impact opportunity to make your mark.

Here’s how you will make a difference in this role… 

• Drive technical quality, scalability and security across applications and integrations
• Lead and uplift engineering standards through mentoring and code reviews
• Partner with Product, Architecture and Business stakeholders to shape solutions
• Champion modern engineering practices including CI/CD, observability and automation
• Contribute to event-driven, cloud-native systems
• Support production environments and lead incidents

• Strong hands-on experience designing, developing and deploying applications using Azure App Services, Azure Functions, Azure Logic Apps, Azure Service Bus,

• Experience with Agentic AI, AI agents and intelligent automation, including using AI to automate business processes, workflows, development tasks or other operational activities. Production experience is highly desirable.
