Automate recurring processes, develop real-time decision-support reporting, lead budgeting and three-year financial modeling, manage cash flow and liquidity, and partner cross-functionally to deliver actionable insights to leadership.

Design and maintain low-latency, high-throughput feature pipelines (batch, streaming, point-in-time), optimize large-scale deep learning training pipelines, integrate embeddings/LLMs for real-time serving, and establish monitoring, testing, and CI/CD standards. Partner with modeling, data science, and infrastructure teams to improve serving latency, training throughput, reliability, and scalability of ad-serving systems.

Design, build, and own backend services and APIs in .NET Core on AWS to power ContextGPT integrations. Drive partner and data-center integrations, resolve scaling challenges, improve performance and reliability, and take end-to-end ownership from design through production operations while collaborating with internal teams and external partners.

Lead architecture and long-term direction of a multi-petabyte data platform powering AI-driven advertising. Drive cross-team initiatives across data engineering, ML, and product; improve scalability, reliability, cost-efficiency, and operational excellence; mentor senior engineers and influence platform strategy and modernization.

Lead research-to-product work on LLM and embedding-driven AdTech features: generate product ideas, prototype with LLMs and embeddings, advance context/persona/embedding models, and take validated concepts end-to-end into production while partnering across research, engineering, product, and marketing.

Drive applied research and development of deep learning and LLM-based solutions for recommendation systems and real-time bidding. Prototype, train, fine-tune, and deploy production-grade ML models, optimize scalability and performance, and collaborate with engineering, product, and platform teams to deliver large-scale AdTech ML systems.

As a Senior Software Engineer, you'll lead the design and reliability of data systems that link ad visibility to customer purchases, focusing on big data engineering and backend service optimization using C#, ClickHouse, and SQL.
