The Role

BTG Pactual is seeking an Infrastructure Specialist to join its Technology team in London. Joining an established international team of professionals, the Infrastructure Specialist will be based in London, whilst operating in a global environment, maintaining regular communication with offices worldwide. The role is hands-on in nature and demands a strong technical grounding across corporate server infrastructure, VMware, Dell server hardware, and Pure storage, complemented by the ability to manage competing priorities, meet deadlines, and resolve complex issues effectively. A core component of the position is ownership of the firm's disaster recovery capability — from the design and implementation of DR solutions, including Zerto replication and failover, through to active participation in DR testing, the development and upkeep of runbooks, and the ongoing refinement of recovery procedures to ensure RTO and RPO targets are consistently met. The successful candidate will also bring demonstrable experience applying AI-powered tools to drive efficiency, whether in building automation scripts, developing infrastructure-as-code templates, or streamlining day-to-day operational workflows.

This is a temp to perm opportunity for an initial period of 12 months, on a Fixed-Term Contract (FTC) basis. Due to ongoing growth within our Technology Team, the intent will be for this position to transition into a permanent role upon the successful completion of the initial 12 month period, subject to performance and business requirements. This is currently a hybrid role requiring a minimum of three days per week in the London office. The successful candidate must have the flexibility to increase office attendance to four or five days per week when business needs, project demands, or critical incidents require on-site presence. As the company continues to evolve, office attendance expectations may be adjusted over time to align with business needs.
