Software Development Engineer II, Ads Demand Tech, Forecasting and Guidance

• Design and implement scalable APIs and microservices that serve real-time forecasting and recommendation results to advertising customers, with a near-term focus on scaling throughput for agentic workloads
• Build and maintain backend data pipelines on EMR, Spark, and S3 that process petabyte-scale datasets, generate search indexes, and keep daily data fresh and accurate
• Collaborate with applied scientists and product teams to translate time-series forecasting models and supply-demand algorithms into production-ready, well-tested systems
• Apply AI-driven approaches to accelerate platform upgrades, reduce tech debt, and lower mean time to resolution for operational issues
• Mentor engineers on your team through code reviews and design discussions, contribute to technical roadmaps, and document systems so they can be maintained and extended by others

Your time splits between proactive, roadmap-driven feature work and hands-on operational responsibilities. In a typical week you might spend mornings writing and reviewing code — building a new forecasting endpoint or tuning a Spark indexing job — then shift to monitoring deployment pipelines, investigating a data-quality anomaly, or reviewing dashboards for latency and forecast accuracy. You will regularly join design reviews and cross-team syncs with product, UX, and science partners.

The role operates with significant autonomy: you own your features end to end, but you are never working in isolation — peer reviews, on-call collaboration, and mentoring newer engineers are woven into the rhythm of the week.
