Duties & Roles
Systems design
- Follows standard approaches and established design patterns to create new designs for simple systems or system components.
- Identifies and resolves minor design issues.
- Identifies alternative design options and seeks guidance when deviating from established design patterns.
Network design
- Specifies the technical configurations and components required for a small network or a network segment in a more complex infrastructure.
- Follows organizational architectures and standards. Systems integration and build
- Defines the software modules needed for an integration build and produces a build definition for each generation of the software.
- Accepts completed software modules, ensuring that they meet defined criteria.
- Produces software builds from software source code for loading onto target hardware.
- Configures the hardware and software environment as required by the system being integrated.
- Produces integration test specifications, conducts tests and records and reports on outcomes.
- Diagnoses faults and records and reports on the results of tests.
- Produces system integration reports. Network support
- Maintains the network support process and checks that all requests for support are dealt with according to agreed procedures.
- Ensures network configurations are applied to meet operational requirements in line with agreed procedures.
- Uses network management software and tools to investigate and diagnose network problems, collect performance statistics and create reports.
Additional duties for this post:
Be responsible for implementing, and maintaining network routing infrastructure. Their duties typically include:
- Network Design & Implementation – Plan, configure, and deploy routing protocols (e.g., OSPF, BGP, IS-IS).
- LA/WAN Optimization – Optimize routing tables and traffic flow for performance and redundancy.
- Troubleshooting & Support – Diagnose and resolve routing issues, including latency, congestion, and failures.
- Security & Compliance – Implement route filtering, prefix lists, and security policies to prevent unauthorized access.
- Capacity Planning – Monitor network usage and plan for scalability and growth.
- Documentation & Reporting – Maintain network diagrams, change logs, and incident reports.
- Collaboration – Work with other teams (e.g., security, data centre, cloud) to ensure seamless connectivity.
- Software & Firmware Management – Upgrade and patch routers to maintain security and stability.
- Testing & Lab Work – Conduct network simulations and testing before deploying changes.
- On-Call Support – Be available on a rotating basis for after-hours network incidents and escalations.
Enterprise Security Operations Center Rotation – Take assigned shifts in the ESOC to monitor and manage network operations in real-time.
