About the role We are looking for a Lead Data Center Engineer to be the technical anchor for Nubank’s physical infrastructure and data center operations, ensuring reliability, scalability, and standardization across our global colocation footprint. The Data Center Eng team owns the physical layer of our infrastructure – from power, cooling, fire protection, security systems to structured cabling and operations – in data centers and technical rooms that host Nubank’s platforms. As a key lead you will be a main point of contact for solving complex infrastructure inquiries, connecting multiple projects and stakeholders, and guiding the standardization of contracts, technical requirements, equipment, and documentation across all our data centers. As a Lead Data Center Engineer, You'll be Responsible For Leading the technical direction of Nubank’s physical infrastructure and data center operations, acting as the main technical reference for the team on all infrastructure-related questions (power, cooling, space, cabling, safety, standards). Owning standardization across all data centers in terms of contracts, technical and operational requirements, equipment, and processes, ensuring a consistent, high-maturity setup in every site. Designing and maintaining robust, senior-level documentation (standards, procedures, runbooks, capacity, topology), making sure it is clear, up to date, and usable by different stakeholders across Nubank. Acting as the primary interface between Nubank teams and external data center providers, translating business needs into infrastructure requirements, work orders, change requests, and negotiations with vendors. Coordinating the design and deployment of infrastructure in third‑party data centers (space, racks, cages, power, cooling, cabling), ensuring compliance with Nubank’s safety, redundancy, and performance requirements – always focused on managing our space in colocation sites, not building our own data centers from scratch. Ensuring alignment between physical infrastructure and IT operations, including service installation, cabling changes, capacity planning, and estimating provider hours needed to deploy or modify environments. Supporting the manager in leading the team technically, helping to decompose work, review solutions, mentor engineers, and be the first escalation point for complex technical decisions so the manager can focus on strategy and broader topics. Interconnecting projects and maintaining standards across multiple data centers, making sure that, over time, all sites converge to the same level of standardization and quality in terms of infrastructure, contracts, and documentation. Driving continuous improvements in availability, resilience, and efficiency of our physical infrastructure (power systems, generators, UPS, cooling, fire protection, structured cabling, and more), in close collaboration with providers and internal stakeholders. Contributing to training and knowledge sharing within the team, helping to design and follow up on technical training, and creating clarity on expectations and standards for the broader group.
