Senior Datacenter Network Build and Migration Engineer Contract engagement | Pune, Chennai, Bengaluru, Mumbai | On-site

We're recruiting for a global payments fintech expanding its APAC datacenter footprint and consolidating legacy environments into a target architecture.

The estate carries live transaction traffic for banks, merchants and financial institutions. Every build and every migration runs through strict change control, and unplanned service impact isn't an option.

You'll work inside their Network Services team, turn HLD and LLD material into workable implementation plans, and support production cutovers with minimal supervision. If you're after a design or oversight position, this isn't it.

The work spans build, migration and relocation activity across Cisco and Arista: preparing runbooks, methods of procedure, rollback and validation plans; configuring and troubleshooting switching,



routing and fabric components; and documenting to a standard the operations team can still use after the project closes.
