Staff Software Engineer at Nubank
Rio de Janeiro, Brazil
Summary
👤
Senior🎓
Top SchoolJade Costa is a Staff Software Engineer based in Rio de Janeiro with 11 years of experience building reliable, scalable systems across mobile, backend and SRE domains. Having progressed from hands-on Android and backend development to tech lead and reliability manager roles at companies like OLX, Globo.com, iFood and Nubank, Jade blends technical depth with people-first leadership and incident/observability strategy. At Nubank they led reliability efforts—shaping observability, alerting and incident tooling—and later returned to an individual contributor SRE-like role, demonstrating a pragmatic focus on operational excellence. Comfortable in many languages and frameworks, Jade ships production services, SDKs and analytics platforms and maintains an active GitHub and personal reading list that reflect continuous learning. What’s less obvious: they intentionally move between management and engineering roles to stay close to systems design while mentoring teams to own quality and autonomy.
