Senior Software Engineer, DevOps

Caliza • New York, NY

3d • Remote

About The Position

Caliza is hiring a Senior Software Engineer, DevOps to own and evolve the infrastructure used to run, ship, and monitor its financial software. The role reports to the security and infrastructure lead, with a focus on DevOps, and combines infrastructure work with production software engineering. The engineer will contribute directly to application services and infrastructure code, following the team's standards for review and testing.

The position is remote and requires at least four hours of overlap with US Eastern time, as well as professional English. During the first six months, the engineer will learn Caliza's infrastructure and deployment pipelines, help build an agentic development environment, improve monitoring and alerting, strengthen and test disaster recovery and backups, and simplify production of compliance evidence.

Caliza handles real-time payments across payment rails and countries, so reliability, security, and safe delivery are central to the work. The company uses AI tools in day-to-day development and expects engineers to understand, test, and take responsibility for changes they ship. Because it handles financial data, Caliza has rules governing which code, configuration, and data may be used with which tools. Benefits vary by country and may include health coverage, paid time off and holidays, a home office or equipment allowance, a professional development budget, and in-person team offsites. Candidates outside the US may be employed through an employer of record or engaged as contractors, with terms structured according to local law and market practice.
