About the role

We are looking for a Technical Program Manager (TPM) at the Senior Staff level to serve as a horizontal technology leader across our Core Infrastructure and Platform teams. At Nubank, a TPM is an Outcome Owner—an engineer at heart with the programmatic capability to lead complex, cross-functional initiatives from inception to production. You are fully accountable for the efficiency, scaling, and modernization of our foundational platforms.

Your mission is to lead horizontal infrastructure transformations at a massive scale. You will optimize database and network utilization, steer regionalization strategies, and guide our architectural evolution—whether that means refactoring monoliths into microservices or right-sizing macro-services. Crucially, you will be at the forefront of integrating AI into our core foundational platforms and ML infrastructure to maximize engineering leverage.

• Own Infrastructure Evolution: Lead programmatic execution for large-scale architectural shifts, including microservices refactoring, service optimization, and complex regionalization strategies.
• Maximize Efficiency & Scale: Drive initiatives to drastically increase hardware, database, and network utilization across our global infrastructure footprint.
• Steer AI/ML Platform Transformations: Own the program roadmap for embedding cutting‑edge AI capabilities and advanced ML infrastructure directly into our foundational core platforms.
• Collaborate Horizontally: Roll up your sleeves to map out and manage deep technical dependencies across disparate infrastructure, data engineering, and platform squads.
• Define North-Star Architecture: Partner with senior engineering stakeholders to determine what our destination, long‑term technical architecture looks like, converting that vision into actionable engineering phases.

Core Qualifications (What We’re Looking For)

• The "Engineer‑First" Background: A proven foundational background as an Infrastructure, Site Reliability (SRE), or Core Backend Engineer earlier in your career before moving into technical program leadership. Please note: This is not a project coordinator role. We require deep technical expertise in these areas to effectively guide the engineering organization.
• Hands‑on Technical Leadership: A strong track record of driving initiatives not just through tracking, but through active technical contribution. You possess the hands‑on technical leadership and ability to unblock teams using your own technical expertise when complex engineering bottlenecks arise.
• Ownership & Entrepreneurial Mindset: A distinct ownership mentality with an entrepreneurial, "raise the bar" attitude. You don't just manage a roadmap; you treat the infrastructure as your own product, constantly pushing for higher standards of engineering excellence, efficiency, and scale.
• High‑Scale Infrastructure Depth: Extensive experience managing massive cloud‑native systems, focusing heavily on core networking, distributed databases, and high‑utilization environments.
• AI Transformation Experience: A highly valued track record of leading or heavily contributing to AI/ML transformation initiatives at scale.
• Architectural Mastery: Proven ability to navigate complex architectural patterns (monoliths, microservices, nano‑services) and successfully execute horizontal multi‑year infrastructure roadmaps.
• Execution Mindset: Strong business acumen, executive communication skills, and a natural ability to step in and aggressively unblock engineering teams in an agile, fast‑moving environment.

• Top Tier Medical Insurance
• Top Tier Dental and Vision Insurance
• 401(k) matching
• 20 days time off, 14 company holidays, and great culture that emphasizes work life balance.
• Life Insurance and AD&D
• Nucleo - Our learning platform of courses
• NuLanguage - Our language learning program
• NuCare - Our mental health and wellness assistance program
• Extended maternity and paternity leaves
• Saving Plans - Health Saving Account and Flexible Spending Account
• Twice a week in the office + quarterly trips to Sao Paulo (Brazil) to build relationships with coworkers.
