Dear Hiring Manager,
I am excited to apply for the Technology Director position at Nubank. As a Brazilian technology leader with over 12 years of experience building scalable engineering organizations across fintech and enterprise software, I am passionate about using technology to simplify people’s lives and increase financial inclusion — a mission I admire deeply in Nubank's work across Brazil and Latin America.
In my most recent role as Head of Engineering at ItaTech Solutions, I led a global team of 85 engineers, product managers, and DevOps practitioners to deliver a cloud-native payments platform that processed over BRL 1.2 billion annually. I drove a migration from monolith to microservices on AWS and Kubernetes that reduced deployment lead time by 70% and lowered infra costs by 28% year-over-year. I implemented engineering KPIs and OKRs, introduced CI/CD pipelines with Jenkins and GitLab, and established robust SRE practices that improved platform uptime from 98.6% to 99.95%. My experience also includes leading machine learning pilots for fraud detection (reducing false positives by 18%) and rolling out GDPR- and LGPD-compliant data governance frameworks.
Beyond technical delivery, I focus on building high-performing, diverse teams. I introduced a mentorship and career-path program that increased internal promotions by 35% and cut attrition among senior ICs by half. I partner closely with product, design, and commercial stakeholders to align tech roadmaps with business priorities, and I have experience managing multi-million-BRL budgets while ensuring predictable delivery and strong ROI. I am fluent in Portuguese and English, and have worked with global partners such as Microsoft Azure, Google Cloud Platform, and HashiCorp tooling.
Nubank's commitment to removing complexity and making banking fair and accessible aligns directly with my values and career goals. I am excited by the opportunity to help scale platforms that serve millions of customers, to strengthen engineering excellence, and to accelerate product innovation while maintaining rigorous reliability and compliance standards. I believe my experience leading cloud transformations, optimizing cost-performance trade-offs, and building inclusive engineering cultures would allow me to contribute immediately to Nubank’s next phase of growth.
I would welcome the opportunity to discuss how my technical leadership, operational rigor, and customer-focused approach can support Nubank’s mission. Thank you for considering my application — I am very enthusiastic about the possibility of joining your team and contributing to transformative products for millions of users.
Sincerely,
Mariana Silva
