What Nubank asks for
From Nubank's Senior Software Engineer ad, checked 2 Nov 2026.
Digital product development
At least 6 years of experience building digital products, with a focus on creating backend applications and a willingness to assist with frontend or mobile tasks as needed.
Distributed systems and cloud
Experience with large scale distributed systems and cloud technologies, including work with microservices and infrastructure as code.
Functional or object-oriented coding
Deep understanding of functional or object-oriented programming. The role primarily uses Clojure, which the team will teach, but requires a strong foundation in one of these paradigms.
Agile and continuous delivery
Hands-on experience using agile methods and working within continuous integration and deployment pipelines to ship code.
Technical design and collaboration
Translating business needs into technical designs, collaborating with product and design teams, and participating in code reviews and on-call rotations.
The ad asks for at least 6 years of experience developing digital products. Based in Toronto.
How the example answers the ad
Three of the five requirements above, each matched to a line in the example.
Distributed systems and cloud
“Led the migration of legacy monolithic banking services to a serverless microservices architecture on AWS.”
Transitioning bank services to serverless microservices on AWS shows the large scale cloud technologies and microservices architecture mentioned in the distributed systems and cloud requirement.
Functional or object-oriented coding
“Mentored four junior engineers on functional programming principles using Scala to improve codebase maintainability.”
Teaching functional programming principles to four engineers using Scala provides evidence of the deep understanding of functional paradigms required for this role.
Technical design and collaboration
“Participated in 24/7 on-call rotations, maintaining system stability during high volatility market events.”
Taking part in 24/7 on-call rotations addresses that specific component of the technical design and collaboration requirement.
