Job description

This is a senior network engineering post in a complex, multi-domain environment where the services on top are mission-critical and the change window is never generous. It is more than incident work: the role contributes to how the service evolves, implements change with the risk understood, and owns the standard operating procedures other engineers follow.

A distinctive part of the job is exercises — designing, configuring and maintaining the routing infrastructure for exercise scenarios and operations, which is where the theory meets a deadline.

What you would be doing

• Provide advanced level three support across complex enterprise network environments.
• Lead the technical resolution of high-impact, high-severity incidents.
• Analyse recurring issues in depth and put sustainable corrective actions in place.
• Help shape and deliver network improvements and new build work, from the drawing board to the change window.
• Ensure technical correctness and minimal service impact during changes and deployments, in line with the change process.
• Perform remote routine maintenance on routing and switching elements across sites.
• Coordinate centralisation, standardisation and best practice for routing and switching.
• Create and maintain the standard operating procedures.
• Design, configure and maintain routing infrastructure for exercise scenarios and operations.
• Coordinate on-site surveys, validation and acceptance testing into the routing infrastructure.
• Keep the technical documentation accurate and share what you learn with the team.

What you would bring

• A bachelor's degree in a related discipline with two years of related experience — or, exceptionally, at least eight years of extensive and progressive expertise in the duties of the post.
• At least eight years in complex network engineering roles.
• Design, implementation and support of scalable enterprise networks using BGP, MPLS, IPv6, OSPF, IS-IS, IP multicast and SD-WAN.
• An active CCNP certification (Enterprise or Service Provider) — this one is required, not preferred.
• Deep BGP knowledge: route reflectors, confederations, communities, path manipulation and filtering.

The work is full time on site in Bydgoszcz.
