You will join a cross-functional product engineering team working on the evolution and modernisation of a core SaaS platform. The focus is on building scalable, cloud-native services while improving reliability, performance, and long-term maintainability.

• Developing and scaling cloud-native solutions on Microsoft Azure
• Working with large, data-heavy systems using SQL
• Improving and refactoring existing systems to support future platform growth
• Writing high-quality, well‑tested, production‑ready code
• Collaborating closely with Product and Engineering peers on delivery and prioritisation
• Supporting a platform used at scale, with a strong focus on performance and reliability

• 7+ years of professional software engineering experience
• Strong, hands‑on experience with the modern .NET stack
• Proven experience building and operating systems on Microsoft Azure
• Solid experience working with SQL in large-scale production environments
• Experience working on complex, long‑lived systems rather than greenfield only
• Strong problem‑solving and analytical skills
• Pragmatic mindset with a focus on delivering value, not over‑engineering
• Comfortable working in Agile, product‑led teams
• Strong communication skills, able to explain technical decisions and trade‑offs clearly
