Sr Software Engineer – Machine Learning

Senior ML Engineer About the Company Our client is a technology company building advanced infrastructure powered by data, machine learning, and AI systems to solve complex problems at scale. They are developing large-scale data pipelines, machine learning models, and agentic systems that enable automated workflows and intelligent decision-making. The team is focused on rapidly taking solutions from concept to production . They are looking for a Senior Software Engineer who wants to work close to the core of the technology stack, building and operating robust AI/ML systems. This position is open to candidates in: Colombia, Argentina, Brazil. What will you do in this role? You will be responsible for designing, building, and operating machine learning systems, large-scale data pipelines, and AI agents that power core product capabilities. This role involves working across the full lifecycle of ML systems — from data ingestion and distributed processing to model deployment and monitoring. Your main responsibilities will include: Designing and building distributed data pipelines to process large datasets. Developing and deploying machine learning models in production environments . Implementing agent-based AI systems that interact with external services and internal infrastructure. Designing scalable architectures for data processing and ML training pipelines . Establishing observability for pipelines, models, and agents (metrics, tracing, alerting). Evaluating modeling approaches and optimizing cost vs. performance trade-offs . Collaborating with product and customer teams to build solutions that drive business impact. Iterating quickly from prototype to production-ready systems . This role requires strong technical ownership and the ability to build reliable systems end-to-end. What should you bring? We are looking for engineers with strong experience in production machine learning systems, distributed data processing, and scalable infrastructure . Ideally you have: Strong experience with Spark and SQL in distributed data environments . Experience building and deploying machine learning systems in production . Experience working with large and complex datasets . Experience designing training, deployment, and monitoring pipelines for ML models . Experience working with cloud services across data, compute, and ML . Ability to design clear software architectures and well-documented systems . Strong technical communication and collaboration skills.
