The Role

As an IT Second-Line Engineer, you’ll be a key escalation point for the Service Desk, resolving technical issues across desktops, servers, networks, and cloud platforms. You’ll communicate and work with clients to resolve issues, foster a documentation-first mindset, learn and collaborate with senior technical staff, troubleshoot alongside and mentor first-line engineers, and contribute to the smooth running of IT operations. This role suits someone who’s hands-on, curious, keeps commitments, and is committed to delivering excellent service while dedicated to personal development.

We’re searching for someone who enjoys solving problems, learning new technologies, and helping others succeed. You take ownership of your work, communicate clearly, and thrive in a fast-paced environment. You manage your time effectively, work with a sense of initiative, and focus on delivering high-quality outcomes efficiently. You’re proactive about improving processes and documentation, and you understand how top-notch IT support can make a real difference to a business.

Today, we provide market-leading solutions in cybersecurity, IT outsourcing, and business continuity—underpinned by a strong focus on IT Risk Management.


What is Spector’s Vision?

Whether it’s helping a client’s staff member with a simple issue or resolving a high-impact incident for an executive, we take ownership and see it through to the best outcome. This clarity of purpose drives our high client retention and attracts like-minded customers to our business.
