• Design, troubleshoot, and improve backend application components in C# to support integrations, fixes, and enhancements.
• Investigate and resolve production issues across databases, applications, integrations, and huge distributed datasets, focusing on root-cause analysis and permanent fixes.
• Support and maintain ERP integrations and APIs, including REST-based services and service layers.
• Monitor system health across Windows Server and SQL Server, proactively addressing performance, stability, and security issues.
• Manage database-related operational tasks including backups, restores, upgrades, patching, and capacity planning for huge distributed datasets.
• Work closely with Engineering, Finance, and Operations teams to prioritise issues and ensure reliable system operation.
• Provide second and third-line support, producing clear documentation for incidents, fixes, and repeatable support processes.
• Assist with finance-critical data accuracy requirements, including reconciliations, postings, journals, and inventory updates.
• Contribute to automation and continuous improvement initiatives across support tooling, monitoring, and processes.

What you'll need:

• Proficiency using AI assisted development tools to support coding, debugging, testing and technical problem solving.
• Strong SQL Server expertise: writing and optimising complex queries, stored procedures, views, indexing strategies, and performance tuning across huge distributed datasets.

• Proven troubleshooting skills in live environments, including logs, databases, integrations, and huge distributed datasets.
• Ability to manage multiple issues and stakeholders with strong prioritisation and time management skills.
• Clear communicator who can collaborate effectively with technical and non-technical teams.
• Analytical mindset with a focus on continuous improvement, automation, and long-term solutions over quick fixes.
