Network Operations Center Engineer

Centroid Solutions is seeking highly skilled and proactive NOC Engineers to join it's IT InfraOps/NOC team. Successful candidates will be responsible for ensuring the stability, performance, and security of the company’s IT infrastructure. This role involves hands-on technical expertise, continuous monitoring, incident response, and collaboration with internal teams and external vendors.

This is a highly hands-on role, requiring a strong engineering mindset. The ideal candidate is expected to actively build, deploy, administer, manage, and troubleshoot a wide range of systems. This is not a coordination or oversight position - success in this role depends on direct technical involvement rather than delegating tasks to external parties.

Candidates with a 5+ years of experience will be considered, with seniority determined based on expertise and depth of technical knowledge.

Before You Apply

This role may not be suitable for you if:

• You need a fixed working schedule (e.g. 9-6) - our work requires adaptability, occasional long hours, and a level of commitment that goes beyond a standard job description. This environment suits people who are willing to put in the extra effort when it’s needed

• You struggle with direct feedback - growth here depends on being open to criticism, adjusting quickly, and maintaining a high level of professionalism even when conversations become challenging

• High-pressure situations overwhelm you - things move fast, expectations are high, and the pace is demanding. We rely on people who remain composed, solution-oriented, resilient under stress, and able to think on their feet

• You are focused on immediate rewards - we operate with a long-term mindset. Sustainable success matters more than quick and easy wins

• Our core values don’t align with yours - a genuine commitment to continuous improvement, perseverance in difficult moments, and uncompromising integrity are non-negotiable in our culture.

If any of the above describe you, it’s likely that another company will better align with your working style and expectations. We believe in mutual fit and encourage you to pursue opportunities that match your strengths and preferences more closely.
