About the Role

The Senior Network Engineer will join the Connectivity Engineering team within Nubank’s Foundation Business Unit, responsible for the core connectivity platforms that support our regulated environments and customer‑facing products in Mexico and across Latin America. Connectivity Engineering designs, builds and operates the network backbone that keeps Nubank’s products securely available to customers around the world and enables our expansion into new countries and partners.

In this role, you will have end‑to‑end ownership across architecture, delivery and operations for regulatory connectivity, product connectivity and third‑party integrations, supporting both on‑premises and cloud environments in a highly available and regulated context. You will help shape our connectivity roadmap, lead critical initiatives, and support the growth of other engineers while remaining hands‑on in production.

You will also play a key role in our multi‑year journey to evolve from traditionally managed networking toward an automation‑, observability‑ and governance‑first connectivity stack, including responsible use of AI to improve reliability and operations.

What You Will Do

You will:

• Design and implement scalable, resilient network solutions aligned with business and regulatory requirements.
• Own High‑Level and Low‑Level Designs (HLD/LLD) for connectivity initiatives across data centers, WAN, cloud edge and partners.
• Build and evolve data center and WAN connectivity platforms (including VXLAN/EVPN fabrics), ensuring reliability, performance and observability at scale.
• Support production environments with incident troubleshooting, change execution and root cause analysis, including participation in a weekly on‑call rotation.
• Manage and improve network observability and monitoring, analyze performance and implement optimizations for speed, reliability and efficiency.
• Conduct network risk assessments and audits, helping ensure compliance with Nubank’s security policies and regulatory requirements.
• Drive automation and observability initiatives, helping us move from manual processes to automation‑ and observability‑driven operations over time.
• Collaborate with Cloud, Security, Infrastructure and Product teams, vendors and partners, improving documentation, standards and operational practices, and mentoring less senior engineers.

• Experience with security tools (IDS/IPS, SIEM) and integrating network telemetry into security monitoring.
• Exposure to AI/ML applications in networking (e.g., anomaly detection, traffic analysis, predictive capacity planning), and interest in helping identify realistic, high‑impact use cases for these capabilities in our environment.

How You Operate

You will fit well if you:
