Software Engineer (Buenos Aires)

Job description

nn

We're looking for a Software Engineer to help maintain, modernize and scale our core production systems. The idóneo candidate thrives in "prod down" scenarios, cares deeply about stability and performance, and is comfortable both refactoring legacy code and building new systems from scratch. You'll join a high-leverage team whose mission is to support high availability, improve observability, reduce technical debt, and enable future growth.

Key Responsibilities:

- Own the health, stability and performance of mission-critical services: respond to incidents, perform root-cause analysis, implement corrective actions and prevent recurrence.

- Diagnose latency, throughput or availability issues in production and design scalable solutions to mitigate risk.

- Refactor or rewrite key processes and subsystems: you'll evaluate existing architecture, propose improvements, and execute on writing code from the ground up where needed.

- Work across the full lifecycle: from design and implementation through CI/CD pipelines, deployment, monitoring and maintenance.

- Collaborate with cross-functional teams (product, operations, QA, DevOps) to define requirements, ensure appropriate SLAs/-SLOs, and deliver robust API and service features.

- Develop and maintain internal tooling, automation and dashboards that improve engineering productivity, operational visibility and run-book execution.

- Champion best practices around code quality, testing (automated and manual), observability/tracing/logging, security, and fault-tolerance.





- Maintain and evolve our infrastructure: containerization (Kubernetes), cloud environment (Azure), relational data stores (SQL) and service communication protocols (HTTP/REST, SOAP, XML-RPC).
