About the Role

We are looking for a Senior Backend (Full Stack) Software Engineer with 10+ years of professional development experience to play a key role in shaping and evolving our core backend platform.

In this role, you will take ownership of the architecture, design, and delivery of scalable, production-grade backend systems built on .NET Core and .NET Framework, supported by high-performance SQL Server data solutions. You will influence technical standards, ensure long-term system reliability, and mentor engineers while remaining hands-on in complex problem-solving.

While the primary focus is backend engineering, you will work closely with frontend engineers building Vue.js applications and contribute to end-to-end solution design. Over time, this role offers a clear pathway toward broader full-stack ownership, with strong influence across the entire application lifecycle. This is an opportunity for a strategic technical leader who enjoys balancing architectural oversight with hands-on execution and meaningful mentorship.

• Design, optimise, and maintain SQL Server databases, schemas, and data access layers

• Guide integration patterns between backend services and Vue.js front-end applications

• Drive improvements in code quality, testing, and CI/CD practices

• Lead and participate in code reviews and architectural discussions

• Mentor and support intermediate and junior engineers

• Identify technical risks early and propose effective mitigation strategies

• Collaborate across distributed teams to influence technical direction and standards

• Communicate progress, dependencies, and risks clearly to both technical and non-technical stakeholders

What You Bring

• 10+ years of professional software development experience

• Deep expertise in C# and .NET Core, with strong experience building RESTful Web APIs

• Proven experience designing and maintaining distributed, enterprise-grade systems

• Advanced Microsoft SQL Server knowledge, including:

  • Schema and data model design

  • Indexing and performance tuning

  • Query optimisation

• Experience implementing and optimising CI/CD pipelines (Azure DevOps or similar)

• Strong understanding of clean architecture, SOLID principles, and design patterns

• Demonstrated experience mentoring engineers and conducting technical reviews

• Excellent communication skills and the ability to explain complex architectural decisions clearly

Education & Experience

• Bachelor’s degree in Computer Science, Software Engineering, or a related field
  or equivalent practical, hands-on experience

• Proven track record of leading backend initiatives and delivering complex systems end-to-end

Why Join Us?

• Work on complex, real-world systems with long-term impact

• Influence architecture and technical direction at a senior level

• Clear growth toward broader full-stack ownership

• Collaborative, engineering-led culture that values quality and maintainability

• Competitive salary and benefits aligned with senior experience
