About the position

We are looking for a Senior Full Stack Developer/Software Engineer who can bring modern machine learning and optimization models into production while working as part of a highly multi-disciplinary team of data scientists, software development engineers, strategic partners, product managers, and subject domain experts. The Senior Engineer will take models developed by the data scientists and integrate them with the rest of the company's platform. This could involve building APIs around the model so that it can be served and consumed, developing user interfaces to visualize and interact with model results, and implementing monitoring capabilities to verify that solutions continue to provide accurate inferences. This position will partner with Data Scientists and Data Engineers to operationalize machine learning and optimization models that deliver new insights to the business. Responsibilities include but are not limited to building data APIs and data delivery services that support critical operational and analytical applications for Delta's internal business operations, customers, and partners. The Senior Engineer will take responsibility for ensuring that model code, data pipelines, APIs, and user interfaces are developed and deployed successfully into production. Troubleshooting issues that arise and supporting production applications will also be part of the role. The engineer will continuously integrate code into Delta's on-premise and AWS cloud environments, transforming data science prototypes into “production-ready” software products. It is essential to ensure a good data flow between database and backend systems, optimize solutions for performance and scalability, and ensure that the Delta methodology, standards, and procedures are implemented. The engineer will also ensure that solutions meet the customers' business goals and that customer satisfaction with the project and conclusion is high. Coordination of activities with internal and external technology service providers, consulting within project team members, other Delta teams, and outside vendors or consultants to ensure product integrity, and coaching and mentoring other developers on the team are also key responsibilities.
