Collaborate with engineering, product management, and business stakeholders to identify opportunities, solve challenges, and drive data-informed decisions.
Monitor and evaluate deep learning and machine learning systems to ensure performance, reliability, and effectiveness in production environments.

A degree in a technical or quantitative field is preferred. Candidates with relevant professional experience and degrees in other disciplines will also be considered.
At least five years of professional experience in data science and/or machine learning within a collaborative work environment.
At least two years of professional experience developing data science and machine learning models in a programmatic advertising environment.
Strong foundation in statistical analysis, deep learning, and machine learning techniques.
Hands-on experience with TensorFlow or PyTorch to prototype models for high-volume, distributed systems.
Experience monitoring and measuring statistical model performance using tools such as Prometheus and Grafana, including building dashboards and alerts to identify performance issues and ensure models function effectively.
Strong organizational, communication, and attention-to-detail skills.
Ability to work efficiently and independently with minimal oversight.
Openness to feedback and constructive criticism, with a commitment to continuous learning and professional development.
Strong work ethic and a demonstrated commitment to delivering high-quality work

At TripleLift, we believe great work starts with great people. We foster a culture built on collaboration, curiosity, and a shared commitment to making each other better.
