As an Application Support Engineer, you’ll join a collaborative, technically curious team supporting and improving critical applications in a Linux-based environment. This role is well suited to someone who already has foundational technical skills and wants to use them every day, deepen their capability, and build a long-term career in modern application support and observability. You’ll work across the full application lifecycle alongside developers, engineers, and stakeholders, contributing meaningfully from day one while continuing to grow your technical and professional skill set. In this role, you’ll be actively involved in the day-to-day health, performance, and improvement of applications, including: Providing Level 2/3 application and systems support in a Linux/Unix environment, with a strong focus on proactive monitoring and performance management.
