Infrastructure Engineer (Initial 12 Month FTC)

BTG Pactual is seeking an Infrastructure Specialist to join its Technology team in London. The role is hands-on, demanding strong technical grounding across corporate server infrastructure, VMware, Dell server hardware, and Pure storage, and the ability to manage competing priorities, meet deadlines, and resolve complex issues. A core component of the position is ownership of the firm’s disaster recovery capability — design, implementation, testing, runbook development, and ongoing refinement of recovery procedures to meet RTO and RPO targets. The successful candidate will also apply AI-powered tools to develop automation scripts, infrastructure-as-code templates, and streamline operational workflows. This is a temp-to-perm opportunity for an initial 12-month fixed-term contract, with the potential to transition to a permanent role upon successful completion. The role is hybrid, requiring a minimum of three days per week in the London office and the flexibility to increase on-site attendance to four or five days when business needs or critical incidents arise.
