Opportunities from Flex

The role focuses on backend engineering for financial products, including card processing and issuing, core ledgering of financial transactions, platform and service development, service and data-model architecture, scalability, security, observability, mentoring and on-call support. The current Flex posting lists annual compensation of $55,000–$100,000. Its Lever header labels the vacancy Remote / Brazil, while the role text separately says it is open to candidates from Canada, the United States and Colombia; applicants should confirm geographic eligibility on the live posting before applying.

Flex asks for proficiency in Node.js and TypeScript, understanding of highly available, scalable, low-latency asynchronous systems, experience evaluating architecture trade-offs, exposure to modular monoliths and microservices, experience with a cloud provider such as Google Cloud, AWS or Azure, and four or more years of relevant industry experience shipping products at scale. The source's location signals are internally inconsistent: the ATS header says Brazil, but the body names Canada, the United States and Colombia as candidate locations.
