Role Summary
The Senior Full-Stack Developer will play a pivotal part in the design, development, and deployment of the organization’s mission-critical SaaS product suite. Embedded within a cross-functional team of Full-Stack engineers, this role requires a technically proficient engineer capable of working across the full software development lifecycle, utilizing modern cloud-native architectures.
The successful candidate will leverage the latest Microsoft technologies, specifically .NET 8+ and Azure PaaS infrastructure, while delivering responsive user interfaces using Angular v18+. Beyond implementation, this role demands a senior level of engagement, requiring active collaboration with both the Technical Lead and Product Owner to translate business needs into scalable technical solutions.
Who we want to work with
We are looking for more than just a skilled developer for this role - we are looking for someone who will act as a true leader within the team. The nature of our work requires individuals who can navigate ambiguity, make sound technical decisions, and take ownership from idea through to delivery and beyond. This role is not about waiting for perfectly defined requirements or relying on constant direction; it’s about actively shaping solutions, contributing to the direction of the platform, and driving meaningful outcomes. By combining strong communication, healthy scepticism, and product awareness, you will help ensure we build the right things in the right way -
balancing speed, quality, and long-term value. Ultimately, we want someone who doesn’t just deliver code, but who elevates the team, influences decisions, and plays a key role in building a scalable, globally aligned platform.
