Senior Database Reliability Engineer (Mexico)

Sezzle is hiring a Senior Database Reliability Engineer based in Mexico, working fully remotely.

The role covers reliability, performance and scalability of the databases behind a payments platform processing millions of transactions, running MySQL, PostgreSQL and Elasticsearch on AWS with Kubernetes.

ABOUT SEZZLE

Sezzle is a NASDAQ-listed fintech company (ticker SEZL) with a mission to financially empower the next generation. Its payment platform provides interest-free installment plans to consumers, driving sales for thousands of eCommerce merchants.

The company reports gross annual revenue above 450 million dollars and net income over 133 million dollars, with roughly 400 employees and contractors. Sezzle also holds B Corp certification.

WHY SEZZLE APPEARS OFTEN ON THIS BOARD

Sezzle is one of the few US fintech companies that hires country by country rather than treating whole regions as an afterthought. Their board carries separate listings for Argentina, Brazil, Chile, Colombia, Mexico, Peru, Turkiye and India, each requiring local work authorisation.

They also publish salary ranges in USD on most listings, which is unusual outside North America and Western Europe, and makes it far easier to judge an offer against the market.

TECHNOLOGY STACK

• Backend: Golang, the primary language for critical services
• Frontend: TypeScript, React and React Native
• Databases: MySQL, PostgreSQL, Elasticsearch
• DevOps and Cloud: AWS, Kubernetes
• Version control and CI/CD: Git, GitLab
• Testing: developer-driven, focused on automated unit, integration and end-to-end tests

Sezzle focuses on open source and builds what it can before buying.

AI EXPERIENCE IS EXPECTED

Sezzle roles consistently ask candidates to demonstrate experience with Claude or equivalent large language model tools. AI-assisted development is treated as a standard part of the job rather than a bonus skill.

INTERVIEW PROCESS

Typically a recruiter screen, then an interview with engineers, then an offer.

ELIGIBILITY

You must hold eligible work authorisation for the country this role is posted in. Applications ask you to confirm this and to state your monthly gross salary expectation in USD. No relocation or visa sponsorship is offered.
