Senior ML Engineer

Workana • Indianapolis, IN

4d • Hybrid

About The Position

Workana is the largest remote work platform for talent in Latin America. Our division focuses on matching exceptional professionals with leading and innovative companies around the globe. About the Client Our client is a U.S.-based organization operating in the life sciences and biotech domain, focusing on complex scientific data and machine learning systems. They are looking for a Senior Machine Learning Engineer with deep industry domain knowledge to join their technical initiatives. While the client prefers a hybrid schedule of 3 days a week in Indianapolis, Indiana (EDT/EST time zone), they are open to fully remote candidates across the East Coast of the U.S. who can travel to Indianapolis occasionally as needed. Role Overview As a Senior Machine Learning Engineer , you will lead the architecture, integration, and scaling of machine learning capabilities within ongoing, production-grade software systems. This role sits at the intersection of machine learning, software engineering, and platform architecture, where your primary focus will be turning models into robust, scalable, and observable production systems rather than pure exploratory research. You will work on an ongoing project, taking ownership of ML pipelines, model integration, and engineering quality. We are seeking a proactive professional with a great attitude who can drive technical execution, collaborate with domain experts, and deliver high-impact solutions. Selection Process The process consists of 3 stages: Initial interview with Workana's recruiting team. People interview with the client's team. Technical Interview with the client's team (rapid fire style). As Workana has multiple clients, if you pass the first round with Workana's recruiting team, you may also be considered for other relevant opportunities if the initial opportunity does not move forward.
