• Partner with Cloud and SRE teams to improve system availability, observability, security, and operational reliability.
• Investigate and resolve complex production issues, identifying root causes and implementing structural improvements to prevent recurrence.
• Contribute to developer experience initiatives that reduce engineering friction and increase team productivity.
• Promote engineering best practices, clean and maintainable code, automated testing, and sustainable software development.
• Share technical knowledge, support other engineers, and contribute to raising the overall technical maturity of the engineering organization.

Requirements:

• Solid professional experience in backend software development using Python, with hands-on experience in frameworks such as Django and/or FastAPI.
• Proven experience building and evolving production-grade APIs and software systems.
• Strong understanding of System Design and the ability to evaluate architectural alternatives and make decisions based on technical trade-offs.
• Experience with distributed systems, service integrations, scalability, and reliability.
• Practical experience with performance analysis, troubleshooting, and the evolution of critical systems.
• Knowledge of relational databases, data modeling, query optimization, and sound persistence practices.
• Experience with automated testing, including unit, integration, and/or end-to-end testing.
• Strong understanding of architecture patterns, software development principles, and engineering best practices.
• Experience with Git and effective version-control and collaborative coding practices.
• Clear communication skills, with the ability to explain technical decisions and collaborate effectively across different teams and disciplines.
• Collaborative profile with the ability to influence technical decisions, work autonomously, and contribute to the growth of other engineers.
• Ability to translate business needs into sustainable technical solutions while balancing simplicity, quality, and continuous improvement.
• Experience with microservices architecture, messaging and asynchronous processing such as Kafka or RabbitMQ, and caching technologies such as Redis is a plus.
• Familiarity with Docker, CI/CD, cloud environments such as AWS, GCP, or Azure, Kubernetes, Terraform, and Infrastructure as Code is desirable.
• Experience with observability tools and practices, including logs, metrics, tracing, Datadog, Grafana, or similar platforms, is an advantage.
• Experience working with platform engineering, architecture, or Developer Experience teams is considered a differentiator.
