• Experience working on live production systems
• Some exposure to Azure or other cloud platforms
• Strong problem-solving ability and attention to detail
• Experience working in Agile teams
• Experience with microservices or distributed systems
• Exposure to CI/CD or DevOps practices
• Any frontend experience (not essential)

What’s on Offer

• £55,000 – £65,000 salary depending on experience
• Hybrid working (Newcastle based team)
• Opportunity to work on large-scale systems with real impact
• Supportive, collaborative engineering environment
• Clear progression and ownership opportunities
