About you

We're looking for a self-motivated, customer-focused Senior Engineer who is passionate about building secure, reliable and scalable platforms that support critical digital services. You thrive in collaborative environments, enjoy mentoring others, and lead through influence rather than authority.

• Experience working with cloud platforms and modern CI/CD practices
  
• Proven ability to deliver reliable, high-quality software in production environments
  
• Experience contributing to incident response and production support in high-availability systems
  
• Strong problem-solving and systems thinking
  
• Highly collaborative, comfortable with pairing, reviews and cross-team work
  
• Takes ownership of outcomes, balancing delivery with reliability, security and operational stability
  
• Able to self-manage and contribute as a de-facto technical leader

Desirable

• Experience with authentication, identity or other highly dependent platforms
• Strong backend engineering practices (e.g. API design, data modelling, concurrency, performance)
  
• Familiarity with microservices, APIs and containerisation
  
• Exposure to monitoring, observability and security practices
  
• Strong communication skills and ability to explain technical concepts clearly
  
• Growth mindset and continuous improvement focus
