About the Role
Nubank is scaling rapidly across Latin America, and our Mexico division is central to empowering millions of people with intuitive, transparent, and accessible financial services. To support our sustained customer growth and expand our product ecosystem reliably, we need senior technical leaders who can translate high-level business vision into resilient, scalable distributed architectures.
In this role, you will serve as a strategic technical anchor across the Mexico division, collaborating closely with engineering leadership and cross-functional teams spanning Growth, Operations, and Core Value Proposition. You will bridge local market dynamics with Nubank's global platform ecosystem, steering architectural decisions that directly impact how prospects seamlessly transition into engaged Nubank customers.
Operating with a country-wide horizontal perspective, you will guide technical roadmaps across multiple business units and squads, untangle complex domain boundaries, and elevate engineering standards across chapters. By pairing architectural vision with pragmatic delivery, you will ensure our systems remain resilient, extensible, and prepared for exponential scale.
Responsibilities
Define and execute the long-term architectural vision for the Mexico division using Domain-Driven Design (DDD) principles to decouple complex systems and eliminate single points of failure.
Steer technical strategy across squads in Growth, Operations, and Core Value Prop, ensuring local business flows integrate seamlessly with Nubank’s global platform foundation.
Mentor and develop senior engineering talent across chapters, cultivating technical excellence, architectural rigor, and operational best practices.
Partner with engineering directors and executive leadership to translate commercial objectives into scalable system designs and actionable execution roadmaps.
Drive cross-team technical consensus on mission-critical initiatives, advocating for sound trade-offs between delivery velocity and platform extensibility.
Champion operational resilience and observability across customer acquisition funnels, proactively identifying bottlenecks to optimize conversion latency and system reliability.
Required Qualifications
Demonstrated track record of technical leadership as a Staff-level engineer (or equivalent scope) guiding distributed systems architecture across multi-team engineering organizations.
Deep practical expertise applying Domain-Driven Design (DDD) to design, decouple, and scale event-driven microservices.
Proven ability to influence cross-functional technical roadmaps across globally distributed platform and product teams without direct hierarchical authority.
Experience architecting mission-critical, high-throughput systems where fault tolerance, reliability, and low-latency performance are essential.
Professional working proficiency in English, with demonstrated success communicating complex architectural concepts to both technical and executive audiences.
Nice to Have
Professional working proficiency in Spanish or prior engineering experience building digital products tailored for the Latin American market (specifically Mexico).
Background designing high-conversion growth, onboarding, or acquisition engines within large-scale consumer technology or high-growth fintech environments.
Hands-on experience with modern cloud-native ecosystems, functional programming paradigms (e.g., Clojure, Scala), or distributed event streaming architectures (e.g., Apache Kafka).
Track record of building and scaling systems at top-tier global technology companies.
Location & Work Model
