Your day at NTT DATA

As a Networking Managed Services Engineer (L2) at NTT DATA, you'll take on a developing engineering role where your main goal is to ensure our clients’ IT infrastructure and systems remain operational. You'll achieve this by proactively monitoring, identifying, investigating, and resolving technical incidents and problems. You’ll work closely with our clients and internal teams to ensure that services are restored swiftly, in line with our service level agreements (SLAs).

Your day will revolve around reviewing client requests and tickets, applying your technical expertise to resolve them efficiently and effectively. You’ll be the go-to person for second‑line support, handling incidents and requests of medium complexity. In addition to your daily tasks, you’ll have opportunities to contribute to exciting project work from time to time.

You’ll proactively monitor work queues, execute operational tasks, and update tickets with the actions you’ve taken. Identifying, analysing, and logging issues before they escalate will be a key part of your role. You’ll communicate with other teams and clients to provide support and ensure that changes are executed with clear risk identification and mitigation plans.

Collaborating with our automation teams, you'll work on optimizing efforts and automating routine tasks, while coaching our Service desk and L1 teams in both technical and behavioural skills.

You’ll also establish monitoring for client infrastructure, lead and manage initial client escalations for operational issues, contribute to change management, log change requests, execute approved maintenance activities, and audit incident and request tickets for quality. Your insights will drive trend analysis reports, identifying tasks suitable for automation to reduce tickets and optimize efforts. You might also support disaster recovery functions and other related tasks as needed.

• At least one relevant technical certification.
• Strong planning skills, with the ability to anticipate and adapt to changing circumstances.
