• Integrate with data products to support reliable, scalable, and efficient data flow.
• Ensure solution quality through testing, observability, performance optimization, and sound technical design.
• Contribute to architecture decisions and continuously improve engineering productivity through automation, modern tools, and emerging AI/ML practices.

What You Will Need:

• Strong backend engineering experience with proficiency in Java and building enterprise-grade APIs and services.
• Experience developing in Azure cloud environments, with familiarity across key Azure services.
• Solid understanding of microservices architecture, REST APIs, and distributed systems.
• At least 1 year of hands-on experience with AI/ML technologies, including LLMs, AI APIs, or ML-enabled features.
• Experience integrating AI capabilities into applications, such as automation, decisioning, or natural language interfaces.
• Demonstrated ability to use AI-assisted development tools to improve engineering productivity.
• Experience working with data pipelines, data products, or data-driven architectures.
• Strong problem-solving skills, with the ability to work effectively in complex enterprise environments.
• Excellent communication and collaboration skills across technical and non-technical stakeholders, with experience working in Agile/Scrum teams.

Additional Desirable Experience

• Advanced experience with AI/ML frameworks, LLM orchestration, or agent-based architectures.
• Experience building AI-driven applications, such as conversational systems, automation workflows, or decision intelligence solutions.
• Familiarity with Azure AI services, data platforms, or MLOps practices.
• Experience with containerization and orchestration tools, including Docker and Kubernetes.
• Exposure to telecom, billing, collections, or financial systems.
• Demonstrated commitment to self-driven AI learning through courses, personal projects, or open-source contributions.

What You Will Bring:

• Bachelor’s degree in Computer Science, Engineering, or a related field.
• Fully bilingual: must speak, read, and write in both Spanish and English.
• The role is based in Mexico City. No relocation is offered. This position is hybrid; you may be expected to go into the office 2 days per week.
