IT Security Technician jobs in England

At Khaos Control, we develop ERP software that helps businesses run their operations every day. Our customers rely on our software to keep their businesses moving, and when they need support, they expect knowledgeable people who care about solving problems and making things happen.

We're building more than a support team. We're building a support function that customers trust, employees are proud to be part of, and the rest of the business looks to as an example of excellence.

We believe exceptional support comes from people who combine technical expertise with curiosity, ownership, great communication and a genuine desire to improve the experience for everyone around them.

Role Purpose

As a Technical Support Engineer, you will investigate and resolve complex customer issues across the Khaos Control platform. The majority of your work will focus on our Windows-based, on-premise ERP solution, alongside supporting our growing SaaS platform.

This is an application support role rather than a traditional IT support position. You'll be comfortable troubleshooting across application, Windows operating system and database layers to identify the root cause of issues, while ensuring every customer receives an outstanding experience.

Beyond resolving tickets, you'll help improve our products, processes, documentation and ways of working. We expect every engineer to leave the team stronger than they found it.

Key Responsibilities

Customer Excellence

• Take ownership of customer issues from initial investigation through to resolution.
• Build confidence by communicating clearly, professionally and proactively.
• Keep customers informed without needing to be chased for updates.
• Explain technical concepts in a way that customers understand.
• Manage customer expectations positively and professionally.
• Handle challenging situations calmly while maintaining trust and confidence.
• Develop long-term relationships with customers through consistently excellent service.

Technical Excellence

• Investigate and resolve complex ERP software issues.
• Diagnose issues across Windows Server environments, application services and supporting infrastructure.
• Troubleshoot software installation, configuration and upgrades within customer environments.
• Investigate SQL databases to identify data issues and root causes.
• Understand how Windows services, permissions, networking and configuration affect application behaviour.
• Work closely with Development to investigate software defects and product improvements.
• Identify and resolve underlying causes rather than simply treating symptoms.
• Produce clear technical investigations that enable rapid and effective resolution.

Continuous Improvement

We expect every engineer to improve the business, not simply support it.

This includes:

• identifying recurring customer pain points
• recommending improvements to products and internal processes
• helping reduce repeat incidents
• improving internal tooling and ways of working
• embracing AI and emerging technologies to improve efficiency and customer outcomes
• contributing ideas that raise the standard of the entire Support function

We value people who challenge the status quo constructively and help drive positive change.

Documentation & Knowledge

We believe documentation is part of engineering, not an afterthought.

You will:

• continuously improve our internal knowledge base
• create documentation that is clear, accurate and easy to follow
• ensure existing documentation remains current and relevant
• share knowledge openly with colleagues
• use AI tools to accelerate documentation while remaining accountable for its quality and accuracy

Team Contribution

• Support and mentor less experienced colleagues.
• Share technical knowledge freely.
• Participate in ticket reviews and technical discussions.
