Application Support Specialist

Are you an experienced Application Support Engineer with strong Linux and Python skills looking for your next opportunity with a leading technology business?

A well-established and highly regarded data platform company near Aylesbury/Milton Keynes Buckinghamshire is looking for a technically capable and proactive Application Support Engineer to join their team — offering a fantastic hybrid role where your Linux expertise and Python knowledge will be put to great use in a dynamic and data-driven environment.

The Role

As Application Support Engineer, you'll play a key role in ensuring the stability, performance, and reliability of a sophisticated data platform. You'll be the go-to technical expert for application support issues, working closely with development, infrastructure, and operations teams to diagnose and resolve problems quickly and effectively. This is a hands-on role that requires strong Linux experience and solid Python skills — someone who is equally comfortable investigating a complex technical issue as they are scripting a solution to prevent it from happening again.

Key Responsibilities

• Providing application support for a leading data platform, taking ownership of incidents, problems, and service requests through to resolution
• Diagnosing and troubleshooting complex technical issues across Linux-based environments, identifying root causes and implementing effective fixes
• Writing, maintaining, and optimising Python scripts to automate processes, improve system performance, and support operational efficiency
• Monitoring platform health and performance, proactively identifying and addressing potential issues before they impact the business
• Working closely with development and infrastructure teams to manage releases, deployments, and configuration changes
• Producing clear and accurate technical documentation including runbooks, incident reports, and knowledge base articles
• Liaising with internal stakeholders and third-party vendors to manage and resolve technical issues effectively
• Contributing to the continuous improvement of support processes, tools, and practices

What We're Looking For

• Proven experience in an application support, systems support, or similar technical role
• Strong, hands-on Linux experience — essential; comfortable working in the command line, managing processes, and troubleshooting system-level issues
• Solid Python scripting skills — able to write, read, and maintain scripts to support automation and problem resolution
• Experience supporting data platforms, data pipelines, or similar data-focused technical environments is highly desirable
• Familiarity with monitoring and alerting tools such as Grafana, Prometheus, Nagios, or similar
• Experience with SQL and database troubleshooting is advantageous
• A methodical, analytical approach to problem solving with strong attention to detail
• Excellent communication skills with the ability to explain technical issues clearly to both technical and non-technical stakeholders
• Based within commuting distance of Aylesbury or Milton Keynes for hybrid working requirements

What's on Offer

• Hybrid working arrangement offering a great balance between office and home working
• The opportunity to join a leading, well-regarded data platform business at an exciting stage of growth
• A technically challenging and varied role with genuine scope to develop your skills and progress your career
• Great benefits
• A collaborative and supportive team environment where your technical expertise will be truly valued
