About 

Our client is building software that helps the construction industry make better financial and delivery decisions at scale. Their platform is complex, data-heavy, and mission-critical - and they are looking for a Principal Full Stack Engineer who enjoys solving hard problems properly.

This is not a feature-factory role. This is ownership, influence, and technical leadership.

You will shape architecture, raise engineering standards, and help steer the evolution of a growing SaaS platform used globally.

What you will own

• End-to-end responsibility for major parts of a complex SaaS product
• Full stack development across front end, back end, and data layers
• Architectural decisions for scalable, cloud-native systems
• Collaboration with Product to shape roadmaps, scope features, and define trade-offs
• Partnership with DevOps to design deployments, reliability, and observability
• Turning ambiguity into working, maintainable solutions
• Leading root-cause analysis, not just fixing symptoms
• Proactive system monitoring and performance optimisation
• Designing software that is fast, reliable, and genuinely pleasant to use
• Acting as a technical role model inside a high-performance global team

What makes you right for this role

• 7+ years building commercial SaaS products
• 7+ years working with cloud-native, containerised systems
• 5+ years with a major cloud provider (AWS preferred)
• Strong experience with microservices and distributed systems
• Deep understanding of object-oriented design and data structures
• Expert SQL skills - schema design, query optimisation, and performance tuning
• Solid knowledge of modern design patterns and SOLID principles
• Comfortable prototyping across multiple technical domains
• Strong Agile mindset with real delivery experience
• Quality is non-negotiable: unit, integration, and end-to-end testing are part of how you think
• You debug methodically, not emotionally
• You work naturally with UX and product teams
• You communicate clearly, even when the topic is complex
• You can turn specifications into production-ready systems

Our core stack

• C#
• .NET 8
• SQL Server
• Vue.js
• TypeScript
• AWS
• Docker
• Kubernetes

You'll stand out even more if you have

• Auth0 experience
• NoSQL exposure
• Background in construction, project controls, or cost management
• Professional certifications in technology, Agile, product, or project management

Why this role

• You will work on software that actually matters to its users.
• You will influence how systems are built, not just what buttons they have.
• You will be trusted as a Principal engineer, not managed like a senior developer.
