ABOUT THE ROLE

The Global Offices Network team enables secure, reliable, and scalable connectivity for Nubank offices worldwide. As Tech Lead, Global Offices Network, you will provide hands-on technical leadership for the end-to-end direction of office networks—from architecture and carrier connectivity to implementation, monitoring, incident response, lifecycle management, and continuous improvement.

You will lead complex technical decisions and delivery across multiple locations, coordinate internal and external partners, and raise the engineering standard through clear ownership, documentation, automation, and knowledge sharing. You will also work directly with AI solutions and agent-orchestration tools to improve infrastructure operations with greater agility and scalability.

YOU'LL BE RESPONSIBLE FOR

- Lead the global networking team in implementing and sustainably supporting infrastructure across multi-site offices.

- Provide technical direction and mentorship to engineers at different levels, supporting their technical and professional growth.

- Define and evolve standards and reference architectures for office LAN, WLAN, WAN, internet edge, firewalls, NAC, segmentation, and observability.

- Lead end-to-end network delivery for new offices, expansions, relocations, and major infrastructure changes, from design through launch and operational handover.

- Own technical designs covering IP addressing, VLANs, routing, wireless, carrier connectivity, resiliency, firewall zones, and enterprise-service access.

- Operate and improve Aruba, Cisco, Palo Alto, SD-WAN, NAC, VPN, and related network platforms.

- Lead complex incidents and escalations, including troubleshooting, root-cause analysis, postmortems, and reliability improvements.

- Maintain monitoring, alerting, capacity planning, lifecycle management, runbooks, rollback plans, and operational handovers for global office infrastructure.

- Drive vulnerability remediation, security-control implementation, audit evidence, and clear RACI definitions across infrastructure operations.

- Coordinate technical work with vendors, carriers, data-center teams, security teams, facilities partners, and other cross-functional stakeholders.

- Run team rituals and coordinate initiatives from ideation through final launch in partnership with peers.

- Promote automation, accurate documentation, knowledge sharing, and AI-enabled practices that reduce operational silos and improve service quality.

WE ARE LOOKING FOR A PERSON WHO HAS

- Experience designing, implementing, and operating enterprise or office networks across multiple sites.

- Hands-on knowledge of LAN, WLAN, WAN, routing, switching, VLANs, IP addressing, DNS/DHCP, and network resiliency.

- Experience designing and operating enterprise firewalls, segmentation, access policies, certificates, firmware, VPNs, and secure network controls.

- Experience with wireless design, RF analysis, access-point planning, authentication, and troubleshooting.

- Experience leading infrastructure projects involving multiple teams, locations, vendors, and physical dependencies.

- Experience with monitoring, alerting, incident response, troubleshooting, post-incident reviews, and reliability improvement.

- Understanding of vulnerability management, audit requirements, security controls, and ownership models such as RACI.

- Experience providing technical direction while remaining comfortable with hands-on implementation and troubleshooting.

- Experience communicating technical decisions, managing stakeholders, documenting systems, and collaborating asynchronously across teams.

- Experience using AI agent-orchestration tools or solutions, such as Claude Code, Cursor, or Gemini, to improve engineering productivity or infrastructure operations.

IT WOULD BE GREAT IF YOU ALSO HAVE

- Experience with Aruba technologies, such as Aruba Central or Aruba ClearPass; Cisco switching; Palo Alto; Fortinet SD-WAN; or IPsec.

- Experience with application delivery controllers, such as F5 BIG-IP or similar platforms.

- Experience with DDI management platforms, such as Infoblox.

- Experience with Prometheus, Grafana, centralized logging, infrastructure as code, or network automation practices.

- Experience delivering new-office, relocation, data-center interconnection, carrier-management, or large-scale workplace-network programs.

- Experience working across international locations and adapting designs to local carrier, building, power, regulatory, and facilities constraints.

- Relevant networking or security certifications, or equivalent practical experience.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
